20250119489
Embodiments of this application relate to the field of terminal technologies, and in particular, to a projection method, an electronic device, and a system.
In daily life or an office process, a user may need to use electronic devices of different forms. Work between a plurality of electronic devices is completed more conveniently and efficiently through collaboration.
For example, documents are stored in a mobile phone, so that the user can carry and view the documents. However, because the mobile phone is not configured with a mouse and a keyboard, editing efficiency is low when a document is directly edited through the mobile phone. In view of this, the mobile phone and a computer may establish a connection based on a multi-screen collaboration technology, and a document editing application on the mobile phone is projected to the computer for display, so that the user can edit the document through a keyboard and a mouse of the computer.
However, a receive end device can display, in a projection window, application projection content sent by a source end device, only after the application projection content is proportionally zoomed in or out based on a size of the projection window, causing a poor display effect.
To resolve the foregoing technical problems, this application provides a projection method, an electronic device, and a system. According to the technical solutions provided in this application, a first electronic device determines, based on an electronic device type supported by an application to be displayed through projection, an application running mode supported by the application. Then, projection is performed based on a first application running mode in the application running mode, to obtain a better projection display effect and meet a user requirement.
To achieve the foregoing technical objective, embodiments of this application provide the following technical solutions.
According to a first aspect, a projection method is provided. The method includes: A first electronic device determines a first application in response to a display request sent by a second electronic device. The first electronic device determines an application running mode supported by the first application, where the application running mode corresponds to one or more electronic device types. The first electronic device sends first projection data of the first application to the second electronic device based on a first application running mode in the application running mode, where the first projection data is used to cause the second electronic device to display the first application in the first application running mode.
In this way, the first electronic device can select, based on the application running mode supported by the first application, the appropriate first application running mode for projection, instead of performing proportional projection only based on a device type of the first electronic device. Therefore, the second electronic device displays the first application in the first application running mode, so that a better display effect can be provided for a user, and user experience can be improved.
In addition, the first application is run on the first electronic device. In view of this, a developer may not need to perform cross-device migration adaptation in an application development process, to reduce a development workload. In addition, the first application may be prevented from being run on the second electronic device, to reduce a risk of information leakage.
According to the first aspect, the application running mode supported by the first application includes one or more of the following: a computer application running mode, a tablet application running mode, a foldable mobile phone application running mode, and a normal mobile phone application running mode.
According to any one of the first aspect or the foregoing implementations of the first aspect, the first application has different interface layouts in different application running modes.
Optionally, in different application running modes, a home page of the first application has different interface layouts. For example, in the computer application running mode, the tablet application running mode, the foldable mobile phone application running mode, and the normal mobile phone application running mode, display elements in the home page of the first application decrease sequentially.
In this way, different application running modes may bring different projection display experience to the user.
According to any one of the first aspect or the foregoing implementations of the first aspect, that the first electronic device sends first projection data of the first application to the second electronic device based on a first application running mode in the application running mode includes: The first electronic device sends the first projection data of the first application to the second electronic device based on the first application running mode with a highest priority in the application running mode.
In this way, the first electronic device makes full use of an application ecosystem, and selects, based on the application running mode supported by the first application, a better application running mode from the application running mode to run the first application in a background. In this way, more display content is displayed on the second electronic device, and better display experience is provided for the user.
According to any one of the first aspect or the foregoing implementations of the first aspect, that the first electronic device sends first projection data of the first application to the second electronic device based on a first application running mode in the application running mode includes: The first electronic device determines a device type of the second electronic device. The first electronic device determines the first application running mode based on the device type of the second electronic device and a priority sequence in the application running mode. The first electronic device sends the first projection data of the first application to the second electronic device based on the first application running mode.
For example, the first electronic device selects an application running mode that corresponds to the device type of the second electronic device and that has a highest priority in the application running mode supported by the first application. For example, the first electronic device determines that the application running mode supported by the first application includes the computer application running mode, the tablet application running mode, and the foldable mobile phone application running mode, and determines that the device type of the second electronic device is a tablet. The first electronic device determines that an application running mode corresponding to the tablet is the tablet application running mode, and the application running mode supported by the first application includes the tablet application running mode. In this case, the first electronic device sends the first projection data of the first application to the second electronic device based on the tablet application running mode (namely, the first application running mode).
In this way, a projection window size of the second electronic device matches the device type of the second electronic device. This improves a projection display effect of the second electronic device, and further improves user experience.
According to any one of the first aspect or the foregoing implementations of the first aspect, the method further includes: in response to an operation of starting the first application on the first electronic device by the user, sending second projection data of the first application to the second electronic device based on a second application running mode corresponding to a device type of the first electronic device, where the second projection data is used to cause the second electronic device to display the first application in the second application running mode; and displaying, by the first electronic device, the first application in the second application running mode.
In this way, in a projection process, in response to the user operation, the first electronic device and the second electronic device can synchronously display the same projection application, to meet a use requirement of the user.
According to any one of the first aspect or the foregoing implementations of the first aspect, the method further includes: The first electronic device receives a first operation indication sent by the second electronic device, where the first operation indication is an indication sent by the second electronic device after the second electronic device detects an operation performed by the user on the first application in a projection window. In response to the first operation indication, the first electronic device sends the first projection data of the first application to the second electronic device based on the first application running mode, and displays the first application in a first window size, where the first window size corresponds to a screen size of the first electronic device, or the first window size is proportional to a second window size corresponding to the first application running mode.
In this way, in the projection process, the first electronic device and the second electronic device can display the same projection application based on the user operation. In additions, different from screen mirroring, display content of the projection application of the first electronic device may be different from display content of the projection application of the second electronic device. On the basis of ensuring that the first electronic device and the second electronic device synchronously display and refresh the projection application, a display effect is further improved, and user experience is improved.
According to any one of the first aspect or the foregoing implementations of the first aspect, the method further includes: The first electronic device displays prompt information in response to an operation of starting the first application on the first electronic device by the user, where the prompt information prompts the user to operate the first application on the second electronic device.

The first electronic device sends third projection data of the first application to the second electronic device based on the second operation indication, where the third projection data causes the second electronic device to display, in the first application running mode, the first application in the projection window whose size is adjusted.
In this way, the projection window is adjusted, so that projection of the second electronic device can better meet a use habit of the user, and user experience is further improved.

The second electronic device displays, in the first application running mode based on the third projection data, the first application in the projection window whose window size is adjusted.
According to any one of the second aspect or the foregoing implementations of the second aspect, when the first application running mode is not the computer application running mode, the method further includes: In response to an operation of adjusting a projection window size by the user, the second electronic device proportionally zooms in or out and displays the projection window and a projection interface of the first application in the projection window.

The following describes the technical solutions in embodiments of this application with reference to the accompanying drawings in embodiments of this application. In the descriptions of embodiments of this application, terms used in the following embodiments are merely intended to describe purposes of specific embodiments, but are not intended to limit this application. The terms “one”, “a”, and “this” of singular forms used in this specification and the appended claims of this application are intended to include expressions such as “one or more”, unless otherwise specified in the context clearly. It should be further understood that in the following embodiments of this application, “at least one” and “one or more” mean one, two, or more.
Reference to “an embodiment”, “some embodiments”, or the like described in this specification indicates that one or more embodiments of this application include a specific feature, structure, or characteristic described with reference to embodiments. Therefore, statements such as “in an embodiment”, “in some embodiments”, “in some other embodiments”, and “in other embodiments” that appear at different places in this specification do not necessarily mean referring to a same embodiment. Instead, the statements mean “one or more but not all of embodiments”, unless otherwise specifically emphasized in another manner. Terms “include”, “contain”, “have”, and variants of the terms all mean “include but are not limited to”, unless otherwise specifically emphasized in another manner. The term “connection” includes a direct connection and an indirect connection, unless otherwise indicated. “First” and “second” are merely intended for a purpose of description, and shall not be understood as an indication or implication of relative importance or implicit indication of a quantity of indicated technical features.
In embodiments of this application, the word “example”, “for example”, or the like is used to represent giving an example, an illustration, or a description. Any embodiment or design scheme described as “example” or “for example” in embodiments of this application should not be explained as being more preferred or having more advantages than another embodiment or design scheme. Exactly, use of the word “example”, “for example”, or the like is intended to present a relative concept in a specific manner.
In some scenarios, with development of terminal technologies, forms of electronic devices are increasingly diversified, for example, include a plurality of forms such as a mobile phone, a computer, and a large-screen device. Electronic devices of different forms have different features. For example, the mobile phone has good portability, and the computer has a good display effect. In daily life or an office process of a user, through cooperative work between a plurality of electronic devices, function use requirements of the user for different electronic devices are met.
For example, a projection connection is established between a first electronic device and a second electronic device. The second electronic device may receive, through the projection connection, projection data sent by the first electronic device, where the projection data is data of an application in the first electronic device. The second electronic device displays a corresponding application interface based on the projection data. In this way, the user may operate the first electronic device and the second electronic device through the second electronic device, to meet a use requirement of the user. The projection process includes, for example, push projection and screen mirroring. In a push projection process, display content of the second electronic device may not be synchronized with display content of the first electronic device. In a screen mirroring process, display content of the second electronic device is synchronized with display content of the first electronic device.
For another example, after establishing a connection to the first electronic device, the second electronic device may obtain application list information of the first electronic device. Then, the second electronic device may display a corresponding application icon in a projection window based on the application list information. In response to an operation performed by the user on the application icon, the second electronic device may request, from the first electronic device, to obtain application data corresponding to the application icon. Then, the second electronic device displays a corresponding application interface in the projection window based on the obtained application data.
It should be understood that the projection method in embodiments of this application may also be applied to screen sharing between devices. A same application is installed on both the first electronic device and the second electronic device. The same application may be understood as an application that is developed by a vendor for adaptation of electronic devices of different forms. After the first electronic device establishes the connection to the second electronic device, the first electronic device and the second electronic device may learn of the same application installed on each other, and present the same application on respective interfaces.
For example, video installed on a tablet computer and a mobile phone can be regarded as a same application. After the mobile phone is connected to the tablet computer, the mobile phone and the tablet computer each may obtain information about a list of applications installed on the peer device. E video icons displayed on the mobile phone and the tablet computer each may have a marker, and the marker indicates that the peer device is also installed with HUAWEI video.
In some embodiments, in response to an operation performed by the user on an icon of a same application, the second electronic device may request the first electronic device to send application data corresponding to the icon of the same application. Then, the second electronic device starts or runs the same application based on the obtained application data, where a window of the same application may be understood as a sharing window. The second electronic device may display a corresponding application interface in the sharing window.
For example, as shown in
Therefore, a multi-screen collaboration method for cross-device migration is proposed. For example, as shown in
However, in the foregoing multi-screen collaboration scenario of cross-device migration, a corresponding projection application needs to be installed on both a source end device (for example, the mobile phone 202) and a receive end device (for example, the computer 201), and an application developer needs to perform cross-device migration adaptation on the application. Consequently, development difficulty is high. In addition, because the application is run in a plurality of electronic devices, information received by the application needs to be transmitted between the plurality of electronic devices, and there is a risk of user privacy leakage.
Therefore, embodiments of this application provide a projection method. In a projection process, a source end device selects, according to a preset rule based on an electronic device form supported by an application, a projection mode with a high priority for projection. Therefore, a receive end device can obtain a better projection effect, and user experience is improved.

An operating system installed on the first electronic device 100 or the second electronic device 200 includes but is not limited to iOS®, Android®, Harmony®, Windows®, Linux®, or another operating system. A specific type of the first electronic device 100 or the second electronic device 200 and an operating system installed on the first electronic device 100 or the second electronic device 200 are not limited in this application.
In some embodiments, a wireless communication connection is established between the first electronic device 100 and the second electronic device 200. A wireless communication technology for establishing the wireless communication connection includes but is not limited to at least one of the following: Bluetooth (BT) (for example, conventional Bluetooth or Bluetooth low energy (BLE)), a wireless local area network (WLAN) (for example, a wireless fidelity (Wi-Fi) network), near field communication (NFC), Zigbee, frequency modulation (FM), infrared (IR), ultra-wideband (UWB), and the like.
Optionally, a communication connection may alternatively be established between a plurality of first electronic devices 100 or a plurality of second electronic devices 200 through a third-party device in a local area network.

In some embodiments, a projection connection is established between the first electronic device 100 and the second electronic device 200 in a plurality of manners such as Bluetooth, a Wi-Fi network, and NFC. The first electronic device 100 may be used as a source end device, and send application data to the second electronic device 200 through the projection connection. The second electronic device 200 may create a projection window, and display a corresponding application interface in the projection window based on the received application data.
Optionally, in the projection process, display content of the first electronic device 100 is the same as or different from display content in the projection window of the second electronic device 200.

Optionally, in the projection process, the second electronic device 200 receives interface display data sent by the first electronic device 100, and displays an application projection interface in the projection window based on the interface display data. Then, after detecting an operation performed by the user in the projection window, the second electronic device 200 may send operation information and coordinate information of the operation to the first electronic device 100. The operation information includes, for example, information about the operation like a tap or touch and hold operation. Then, the first electronic device 100 may determine the user operation based on the operation information and the coordinate information of the operation, and send corresponding interface display data to the second electronic device 200, so that the second electronic device 200 displays an interface that the user operation indicates to display.
For example, as shown in
Alternatively, in a projection process, the second electronic device 200 may obtain application list information of the first electronic device 100, and then the second electronic device 200 may display, in the projection window based on the application list information, an application icon of an application in the first electronic device 100. Then, after detecting an operation of tapping the application icon in the projection window by the user, the second electronic device 200 may determine the application that the operation is used to request to start, and send a display request to the first electronic device 100. The display request is used to request to display the application corresponding to the application icon operated by the user. Then, the first electronic device 100 may send corresponding projection data to the second electronic device 200 based on the display request, so that the second electronic device 200 displays an interface that the user operation indicates to display.
For example, as shown in
It should be noted that, in embodiments of this application, a projection scenario in each embodiment is described by using an example in which the first application is an application market. It may be understood that the first application may alternatively be another application. For example, the first application may be a system application like a desktop or a notepad, or may be a third-party application. This is not limited herein. Optionally, the first application is an application in the first electronic device 100, and the first application may not be installed on the second electronic device 200.
In addition, in the following example, the projection method provided in embodiments of this application is described by using an example in which the first electronic device 100 determines the first application in response to the user operation, and requests the second electronic device 200 to obtain the projection data of the first application. As described above, in the projection process, the second electronic device 200 may alternatively send the projection data to the first electronic device 100 after determining the first application in response to the display request sent by the first electronic device 100. This is not described by using examples one by one in embodiments of this application.
In some embodiments, different types of electronic devices (such as a mobile phone, a tablet, and a computer) have different color styles, screen sizes, interaction manners, system functions, and the like. In an application development process, a developer may configure a set of code and an installation package for a plurality of different types of electronic devices to share, so that an application supports the corresponding plurality of types of electronic devices. In this way, application ecosystems of different types of electronic devices are enriched, and application adaptability and development efficiency are improved.
Optionally, the application includes different application running modes, for example, a computer application running mode, a tablet application running mode, a foldable mobile phone application running mode, and a normal mobile phone application running mode. Different application running modes correspond to different types of electronic devices.
For example, in response to an operation of starting an application at the electronic device by the user, the electronic device may start and display an application interface in a corresponding application running mode based on a device type of the electronic device. For example, the first electronic device 100 is a mobile phone, and the first application is installed. In response to an operation of starting the first application on the first electronic device 100 by the user, the first electronic device 100 runs the first application in the normal mobile phone application running mode.
Optionally, the first application that is run in different application running modes has different interface layouts. It should be understood that, after the application is started, an interface layout may include distribution data of display elements of the application.
For example, as shown in
It can be learned that, in different application running modes, the home page of the first application has different interface layouts. For example, in the computer application running mode, the tablet application running mode, the foldable mobile phone application running mode, and the normal mobile phone application running mode, display elements in the home page of the first application decrease sequentially.
It should be noted that, in embodiments of this application, an example in which the application running mode includes the computer application running mode, the tablet application running mode, the foldable mobile phone application running mode, and the normal mobile phone application running mode is used to describe projection processes of the application in different application running modes. It may be understood that the application may further support another application running mode, to match another type of electronic device.
In some embodiments, in the projection process, after receiving the display request sent by the second electronic device 200, the first electronic device 100 may determine that the display request is used to request to display the first application, and determine the application running mode supported by the first application. Then, the first electronic device 100 determines, in a preset manner, an application running mode to be used by the first application in the projection process. The first electronic device 100 runs the first application in a background in the determined application running mode, and sends projection data of a window size corresponding to the corresponding application running mode to the second electronic device 200, so that the second electronic device 200 displays the first application through projection in the window size corresponding to the application running mode.
For example, as shown in the following Table 1, in different application running modes, window sizes in which the first electronic device 100 runs the first application in the background are different. For example, in the tablet application running mode, the first electronic device 100 runs the first application in the background in a default screen size of a tablet. In this way, after obtaining the projection data, the second electronic device 200 creates a projection window based on the default screen size of the tablet, to display the first application.
Optionally, the first electronic device 100 determines that a device type corresponding to the application running mode of the first application is the same as a device type of the first electronic device 100, and may run the first application in the background in a screen size of the first electronic device 100. For example, the first electronic device 100 is a mobile phone, and the first electronic device 100 determines that the application running mode in which the first application is run in the background is the normal mobile phone application running mode. In this case, the window size in which the first electronic device 100 runs the first application in the background is the screen size of the first electronic device 100.
For example, as shown in the following Table 2, window sizes, for example, window parameters, in which the first application is run in the background in different application running modes are listed. It should be understood that the parameters in the following Table 2 are merely examples for description, and do not constitute a limitation on the window size in which the first application is run in the background in embodiments of this application.
Optionally, as shown in Table 1, in different application running modes, window sizes in which the application is run are different. Different content may be displayed in different window sizes. For example, a larger window size indicates richer display content, and different window sizes may bring different display experience to the user. Therefore, a priority sequence of different application running modes may be determined based on window sizes. For example, a larger window size can bring better display experience to the user, and therefore a corresponding application running mode may have a higher priority. For example, the four application running modes shown in the foregoing Table 1 may be sequentially the computer application running mode, the tablet application running mode, the foldable mobile phone application running mode, and the normal mobile phone application running mode in descending order of priority.
Optionally, the foregoing preset manner includes, for example, that the first electronic device 100 determines that a to-be-used application running mode is an application running mode with a highest priority in the application running mode supported by the first application. In this way, the second electronic device 200 may bring optimal display experience to the user.
For example, in the scenario shown in
For example, as shown in
Optionally, an application display response sent by the first electronic device 100 to the second electronic device 200 carries the projection data and the window size, and the second electronic device 200 may determine the window size based on the application display response, to create the new projection window. Alternatively, the second electronic device 200 determines the window size based on the projection data, to create the new projection window.
For another example, as shown in
For another example, as shown in
For another example, as shown in
As shown in the content in
In some embodiments, the first application is run on the first electronic device 100. In view of this, the developer may not need to perform cross-device migration adaptation in the application development process, to reduce a development workload. In addition, the first application may be prevented from being run on the second electronic device 200, to reduce a risk of information leakage.
Optionally, the foregoing preset manner may further include, for example, that the first electronic device 100 determines a to-be-used application running mode based on a device type of the second electronic device 200 and the application running mode supported by the first application. For example, the first electronic device 100 selects an application running mode that corresponds to the device type of the second electronic device 200 and that has a highest priority in the application running mode supported by the first application. In this way, a projection window size of the second electronic device 200 matches the device type of the second electronic device. This improves a projection display effect of the second electronic device 200, and further improves user experience.
In a process of establishing the projection connection to the second electronic device 200, the first electronic device 100 may determine the device type of the second electronic device 200. Alternatively, the first electronic device 100 may determine the device type of the second electronic device 200 based on device type information carried in the received display request sent by the second electronic device 200. Alternatively, the first electronic device 100 sends a request to the second electronic device 200, where the request is used to request to obtain the device type of the second electronic device 200. Alternatively, the first electronic device 100 may determine the device type of the second electronic device 200 in another manner.
For example, the first electronic device 100 determines that the application running mode supported by the first application includes the computer application running mode, the tablet application running mode, the foldable mobile phone application running mode, and the normal mobile phone application running mode, and determines that the device type of the second electronic device 200 is a tablet. The first electronic device 100 determines that an application running mode corresponding to the tablet is the tablet application running mode, and the application running mode supported by the first application includes the tablet application running mode. In this case, as shown in Table 1, the first electronic device 100 runs the first application in the background in the default screen size of the tablet, and sends the corresponding projection data to the second electronic device 200, so that the second electronic device 200 creates the projection window based on the default screen size of the tablet, and displays the first application interface.
For another example, the first electronic device 100 determines that the application running mode supported by the first application includes the tablet application running mode, the foldable mobile phone application running mode, and the normal mobile phone application running mode, and determines that the device type of the second electronic device 200 is a computer. The first electronic device 100 determines that an application running mode corresponding to the computer is the computer application running mode, the application running mode supported by the first application does not include the computer application running mode, and a priority of the computer running mode is higher than a priority of the application running mode supported by the first application. In this case, the first electronic device 100 may determine that the to-be-used running mode is an application running mode with a highest priority in the application running mode supported by the first application, for example, the tablet application running mode. As shown in Table 1, the first electronic device 100 runs the first application in the background in the default screen size of the tablet, and sends the corresponding projection data to the second electronic device 200, so that the second electronic device 200 creates the projection window based on the default screen size of the tablet, and displays the first application interface.
In some embodiments, in the projection process, after detecting an operation performed by the user in the projection window, the second electronic device 200 may generate a corresponding input event, and send the input event to the first electronic device 100. In this case, the first electronic device 100 may send, to the second electronic device 200 based on the input event, application display content indicated by the user operation.
Optionally, the input event generated by the second electronic device 200 further includes coordinate information corresponding to the user operation. In this way, the first electronic device 100 may run a corresponding function of the application in the background based on the coordinate information, to generate the projection data. For example, the first electronic device 100 determines, based on the coordinate information, that the user performs an operation on the application icon of the first application, and may start the first application in the background, to generate the projection data corresponding to the first application.
For example, as shown in
Herein, x_pc and y_pc indicate coordinates on the computer, x_phone and y_phone indicate coordinates on the mobile phone, w_pc and h_pc indicate a width and a height of a window of the computer, and w_phone and h_phone indicate a width and a height of a window in which the first application is run in the background of the mobile phone.
Optionally, in the process of establishing the projection connection to the second electronic device 200, the first electronic device 100 may obtain a screen size of the peer device.
Optionally, in response to the user operation, the second electronic device 200 may determine the corresponding coordinate information according to the foregoing formula, and then send the coordinate information to the first electronic device 100. Alternatively, after detecting the user operation, the second electronic device 200 may directly send the coordinate information of the user operation to the first electronic device 100, and then the first electronic device 100 converts, according to the foregoing formula, the obtained coordinate information into coordinate information applicable to the first electronic device.
In some embodiments, the second electronic device 200 may detect a gesture operation of the user in the projection window. In this case, the second electronic device 200 may map the detected gesture operation to a corresponding operation of the first electronic device 100, so that the first electronic device 100 determines a meaning of the user operation. Alternatively, the second electronic device 200 sends the detected gesture operation to the first electronic device 100, and the first electronic device 100 maps the gesture operation to a corresponding operation of the first electronic device 100, to determine a meaning of the user operation.
Optionally, after detecting the gesture operation, the second electronic device 200 may send, to the first electronic device 100, an input event that includes a gesture operation event and coordinate information, to obtain corresponding application display data.
For example, as shown in the following Table 3, an example in which the first electronic device 100 is a mobile phone and the second electronic device 200 is a computer is used. The computer may support at least one of a touchscreen gesture input, a mouse input, and a touch panel input. After detecting an operation performed by the user in the projection window, the computer may map the operation to an input event corresponding to the mobile phone, and send the input event to the mobile phone, to display, in the projection window, an application interface indicated by the user operation.
For example, as shown in the following Table 3, when detecting that a touchscreen gesture of the user is a tap with one finger, the computer may map the user operation to a tap operation. Alternatively, the computer directly sends the detected user operation to the mobile phone, and then the mobile phone maps the user operation to an input event on the mobile phone. For example, the computer detects that a touchscreen gesture of the user is a tap with one finger, and sends the user operation to the mobile phone. The mobile phone maps the user operation to a tap operation.
In some embodiments, the second electronic device 200 may adjust the projection window size in response to an operation of adjusting the projection window size by the user, and display the projection content based on an adjusted projection window size.
Optionally, an application in different application running modes may support user-defined window size adjustment or proportional window size adjustment. The computer application running mode, the tablet application running mode, the foldable mobile phone application running mode, and the normal mobile phone application running mode are still used as examples. The first application that is run in the computer application running mode supports user-defined window size adjustment, and allows the user to separately adjust a width and a height of a window. The first application that is run in the tablet application running mode, the foldable mobile phone application running mode, or the normal mobile phone application running mode supports proportional window size adjustment, and only allows the user to adjust a width and a height of a window at the same time, and in the window size adjustment process, an aspect ratio of the window remains unchanged.
For example, after detecting the operation of adjusting the projection window size by the user, the second electronic device 200 determines that an application running mode of the first application displayed in the current projection window supports user-defined window size adjustment. In this case, the second electronic device 200 may allow the user to separately adjust the width and the height of the projection window, generate a window size adjustment event corresponding to the user operation, and send the window size adjustment event to the first electronic device 100. The first electronic device 100 may generate corresponding application projection data based on the window size adjustment event, to display a new application interface in the projection window whose window size is adjusted and that is of the second electronic device 200.
For example, in the scenario shown in
For another example, after detecting the operation of adjusting the projection window size by the user, the second electronic device 200 determines that an application running mode of the first application displayed in the current projection window supports proportional window size adjustment. In this case, the second electronic device 200 may proportionally zoom in or out the projection window and display content in the projection window in response to the user operation, so that the display content matches an adjusted projection window size. In the process of adjusting the projection window size, the first electronic device 100 does not need to respond to the operation of adjusting the projection window size by the user.
For example, in the scenario shown in
In this way, the projection window is adjusted, so that projection on the second electronic device 200 can better meet a use habit of the user, and user experience is further improved.
In some embodiments, in response to the operation of adjusting the projection window size on the second electronic device 200 by the user, the first electronic device 100 determines that an adjusted projection window size corresponds to a window size corresponding to another application running mode, and may switch the application running mode of the first application. In this way, in the projection process, the projection content better matches the projection window size, and the second electronic device 200 can obtain a better display effect of the first application.
For example, in the process in which the first electronic device 100 projects the first application to the second electronic device 200 in the computer application running mode, the second electronic device 200 detects an operation of adjusting the projection window size by the user, generates a corresponding window size adjustment event, and sends the corresponding window size adjustment event to the first electronic device 100. The first electronic device 100 determines, based on the window size adjustment event, that the user indicates to reduce the projection window, and determines that a reduced window size corresponds to a window size in which the first application is run in the background in the tablet application running mode. In this case, the first electronic device 100 may switch the application running mode of the first application from the computer application running mode to the tablet application running mode, and then run the first application in the background in the default screen size of the tablet corresponding to the tablet application running mode, and the first application is displayed on the second electronic device 200 through projection.
Subsequently, for example, the second electronic device 200 further detects an operation of adjusting the projection window size by the user, generates a corresponding window size adjustment event, and sends the corresponding window size adjustment event to the first electronic device 100. The first electronic device 100 determines, based on the window size adjustment event, that the user indicates to enlarge the projection window, and determines that an enlarged window size corresponds to a window size in which the first application is run in the background in the computer application running mode. In this case, the first electronic device 100 may switch the application running mode of the first application from the tablet application running mode back to the computer application running mode, and then run the first application in the background in the default window size of the computer application corresponding to the computer application running mode, and the first application is displayed on the second electronic device 200 through projection.
In some embodiments, after receiving the projection data sent by the first electronic device 100, the second electronic device 200 may create the new projection window, to display the first application interface in the new projection window based on the projection data. Alternatively, the second electronic device 200 may adjust, based on the projection data, the size of the projection window on which the user operation is detected, to display the first application interface. Optionally, the second electronic device 200 may display a preset quantity of projection windows.
For example, in the scenario shown in
Alternatively, as shown in
In this way, the second electronic device 200 may perform projection display based on a user operation, to meet a use requirement of the user.
Optionally, in the foregoing embodiments, the projection process is described by using an example in which the second electronic device 200 requests to obtain projection data of an application in the first electronic device 100 in response to an operation performed by the user on a projection desktop. It may be understood that the first electronic device 100 may alternatively determine a to-be-projected application based on an operation performed by the user on the first electronic device 100, to determine a corresponding application running mode, generate projection data, and implement application projection display on the second electronic device 200. For the process of determining the application running mode, refer to related content described in the foregoing embodiments. Details are not described herein again.
In a scenario, in a projection process, the first electronic device 100 and the second electronic device 200 may not need to support simultaneous display of a projection application. In this way, the first application in the first electronic device 100 is displayed on the second electronic device 200 through projection, and running of another application on the first electronic device 100 is not affected.
In some embodiments, in the projection process, the first electronic device 100 detects an operation of starting the first application on the first electronic device 100 by the user, and may prompt the user that the first application has been projected to the second electronic device 200 and the first application needs to be operated on the second electronic device 200. Subsequently, for example, after the second electronic device 200 stops projection of the first application in response to a user operation, the user may use the first application on the first electronic device 100.
For example, in the scenario shown in
In another scenario, in the projection process, the first electronic device 100 and the second electronic device 200 support display of a same projection application, and support synchronization of display content of the projection application.
In some embodiments, in a process in which the first electronic device 100 projects the first application to the second electronic device 200 for display, the second electronic device 200 creates a new projection window to display a first application interface, and the first electronic device 100 runs only the first application in the background, and does not display the interface of the first application. Then, the first electronic device 100 detects an operation of starting the first application on the first electronic device 100 by the user, and the first electronic device 100 may display, in response to the user operation, a first application interface on the first electronic device 100 in the process of projection of the first application.
In some embodiments, to ensure that an electronic device operated by a user refreshes and displays an application interface in real time in response to a user operation, the electronic device operated by the user is set as a primary device, and a window size in which the first electronic device 100 runs the first application in the background needs to be consistent with a requirement of the primary device. A peer electronic device of the primary device is set as a secondary device, and in response to a user operation, roles of the primary device and the secondary device may be freely switched.
The first electronic device 100 determines display of the secondary device based on display content of the primary device and a screen size of the secondary device in response to a user operation, so that the first electronic device 100 and the second electronic device 200 simultaneously display the first application that is being projected.
In some embodiments, the first application run in the computer application running mode, the foldable mobile phone application running mode, the tablet application running mode, or the normal mobile phone application running mode is still used as an example. A foldable mobile phone supports two use forms: a folded state and an unfolded state, and a corresponding foldable mobile phone application also supports to be displayed in the two use forms. Display content of the first application may be different in different use forms. As described above, in the computer application running mode user-defined window size adjustment is supported, and the user is allowed to adjust a width and a height of a window. Display content varies with different window sizes. Therefore, when the first application is run in the computer application running mode or the foldable mobile phone application running mode, display content of the first application on the first electronic device 100 may be different from that on the second electronic device 200.
Optionally, an example in which the first electronic device 100 is a mobile phone and the second electronic device 200 is a computer is used. As shown in the following Table 4, when the first application is run in the computer application running mode or the foldable mobile phone application running mode, a window size (corresponding to a size of a projection window of the second electronic device 200) in which the first electronic device 100 (for example, a mobile phone) runs the first application in the background and a window size in which the first electronic device 100 displays the first application when the second electronic device 200 (for example, a computer) is a primary device and a window size (corresponding to the size of the projection window of the second electronic device 200) in which the first electronic device 100 runs the first application in the background and a window size in which the first electronic device 100 displays the first application when the first electronic device 100 (or example, the mobile phone) is a primary device are described separately as examples.
For example, as shown in
Then, as shown in
For another example, as shown in
Then, as shown in
In this way, in the projection process, the first electronic device 100 and the second electronic device 200 can display the same projection application based on the user operation. In additions, different from screen mirroring, display content of a projection application of the first electronic device 100 may be different from display content of the projection application of the second electronic device 200. On the basis of ensuring that the first electronic device 100 and the second electronic device 200 synchronously display and refresh the projection application, a display effect is further improved, and user experience is improved.
In another implementation, the first application run in the tablet application running mode, the normal mobile phone application running mode, the computer application running mode, or the foldable mobile phone application running mode is still used as an example. In a display process of a normal mobile phone application and a tablet application, an application window size does not change. Therefore, when the first application is run in the tablet application running mode or the normal mobile phone application running mode, display content of the first application on the first electronic device 100 is the same as that on the second electronic device 200.
Optionally, an example in which the first electronic device 100 is a mobile phone and the second electronic device 200 is a computer is still used. As shown in the following Table 5, when the first application is run in the tablet application running mode or the normal mobile phone application running mode, a window size (corresponding to a size of a projection window of the second electronic device 200) in which the first electronic device 100 (for example, a mobile phone) runs the first application in the background and a window size in which the first electronic device 100 displays the first application when the second electronic device 200 (for example, a computer) is a primary device and a window size (corresponding to the size of the projection window of the second electronic device 200) in which the first electronic device 100 runs the first application in the background and a window size in which the first electronic device 100 displays the first application when the first electronic device 100 (or example, the mobile phone) is a primary device are described separately as examples.
For example, as shown in
Then, as shown in
For another example, as shown in
Then, as shown in
In this way, in a projection process, in response to the user operation, the first electronic device 100 and the second electronic device 200 can synchronously display the same projection application, to meet a use requirement of the user.
For example,
S1601: A second electronic device sends a display request to a first electronic device.
Optionally, the display request is a request sent by the second electronic device in response to an operation performed by a user on a projection window. The display request carries coordinate information and operation information that correspond to a user operation, the coordinate information indicates a location of the user operation in the projection window, and the operation information indicates the user operation like a tap and a double-tap.
For example, as shown in
S1602: The first electronic device determines the first application in response to the display request sent by the second electronic device.
In some embodiments, after receiving the display request, the first electronic device can determine, based on the coordinate information and the operation information that are carried in the display request, an application that the user indicates to perform projection.
For example, as shown in
S1603: The first electronic device determines an application running mode of the first application.
The application running mode corresponds to one or more electronic device types. Optionally, the application running mode supported by the first application includes one or more of the following: a computer application running mode, a tablet application running mode, a foldable mobile phone application running mode, and a normal mobile phone application running mode.
In some embodiments, after determining the first application, the first electronic device may determine, by using a configuration file of the first application or querying a second application, the application running mode supported by the first application. The second application is an application market.
In some embodiments, the first application has different interface layouts in different application running modes.
For example, as shown in
It can be learned that, in different application running modes, the home page of the first application has different interface layouts. For example, in the computer application running mode, the tablet application running mode, the foldable mobile phone application running mode, and the normal mobile phone application running mode, display elements in the home page of the first application decrease sequentially.
In this way, different application running modes may bring different projection display experience to the user.
S1604: The first electronic device sends first projection data to the second electronic device based on a first application running mode in the application running mode of the first application.
Optionally, as shown in Table 1, in different application running modes, corresponding projection window sizes are different. Different content may be displayed in different window sizes. For example, a larger window size indicates richer display content, and different window sizes may bring different display experience to the user. Therefore, a priority sequence of different application running modes may be determined based on window sizes. For example, a larger window size can bring better display experience to the user, and therefore a corresponding application running mode may have a higher priority.
In some embodiments, the first electronic device sends the first projection data of the first application to the second electronic device based on the first application running mode with a highest priority in the application running mode.
For example, after determining the application running mode supported by the first application, the first electronic device may determine the first application running mode with the highest priority in the application running mode. In this way, the first projection data is sent to the second electronic device based on the first application running mode, so that the second electronic device can provide better display experience for the user.
In this way, the first electronic device makes full use of an application ecosystem, and selects, based on the application running mode supported by the first application, a better application running mode from the application running mode to run the first application in a background. In this way, more display content is displayed on the second electronic device, and better display experience is provided for the user.
In some other embodiments, the first electronic device determines a device type of the second electronic device. Then, the first electronic device determines the first application running mode based on the device type of the second electronic device and a priority sequence in the application running mode, and sends the first projection data of the first application to the second electronic device based on the first application running mode.
For example, the first electronic device selects an application running mode that corresponds to the device type of the second electronic device and that has a highest priority in the application running mode supported by the first application. For example, the first electronic device determines that the application running mode supported by the first application includes the computer application running mode, the tablet application running mode, the foldable mobile phone application running mode, and the normal mobile phone application running mode, and determines that the device type of the second electronic device is a tablet. The first electronic device determines that an application running mode corresponding to the tablet is the tablet application running mode, and the application running mode supported by the first application includes the tablet application running mode. In this case, the first electronic device sends the first projection data of the first application to the second electronic device based on the tablet application running mode (namely, the first application running mode).
In this way, a projection window size of the second electronic device matches the device type of the second electronic device. This improves a projection display effect of the second electronic device, and further improves user experience.
S1605: The second electronic device displays the first application in the first application running mode based on the first projection data.
In some embodiments, after receiving the projection data, the second electronic device may determine a corresponding projection window size based on the projection data. Then, the second electronic device may display the first application in a projection window based on the determined projection window size.
In this way, the first electronic device can select, based on the application running mode supported by the first application, the appropriate first application running mode for projection, instead of performing proportional projection only based on a device type of the first electronic device. Therefore, the second electronic device displays the first application in the first application running mode, so that a better display effect can be provided for the user, and user experience can be improved.
In addition, the first application is run on the first electronic device. In view of this, a developer may not need to perform cross-device migration adaptation in an application development process, to reduce a development workload. In addition, the first application may be prevented from being run on the second electronic device, to reduce a risk of information leakage.
In some embodiments, in response to an operation of starting the first application on the first electronic device by the user, second projection data of the first application is sent to the second electronic device based on a second application running mode corresponding to the device type of the first electronic device; and the first electronic device displays the first application in the second application running mode. The second projection data is used to cause the second electronic device to display the first application in the second application running mode.
For example, as shown in
An application running mode in which the first electronic device runs the first application in the background corresponds to the first electronic device, for example, a mobile phone application running mode (namely, the second application running mode), and sends the second projection data to the second electronic device in the mobile phone application running mode, to implement projection display of the first application on the second electronic device.
Optionally, based on the foregoing scenario, the second electronic device sends a first operation indication to the first electronic device after detecting an operation performed by the user on the first application in the projection window. Correspondingly, the first electronic device receives the first operation indication sent by the second electronic device, sends, in response to the first operation indication, the first projection data of the first application to the second electronic device based on the first application running mode, and displays the first application in a first window size, where the first window size corresponds to the screen size of the first electronic device, or the first window size is proportional to a second window size corresponding to the first application running mode. Correspondingly, the second electronic device receives the first projection data sent by the first electronic device, and displays the first application in the projection window in the first application running mode based on the first projection data.
For example, as shown in
An application running mode in which the first electronic device runs the first application in the background corresponds to the second electronic device, for example, a tablet application running mode (namely, the first application running mode), and sends the first projection data to the second electronic device in the tablet application running mode, to implement projection display of the first application on the second electronic device. In addition, display content in the tablet application running mode is proportionally zoomed in or out on the first electronic device, to synchronously display the first application on the first electronic device.
In this way, in a projection process, in response to the user operation, the first electronic device and the second electronic device can synchronously display the same projection application, to meet a use requirement of the user.
In some other embodiments, the first electronic device displays prompt information in response to an operation of starting the first application on the first electronic device by the user, where the prompt information prompts the user to operate the first application on the second electronic device.
For example, in the scenario shown in
In some embodiments, when the first application running mode is the computer application running mode, the second electronic device sends a second operation indication to the first electronic device when the second electronic device detects an operation of adjusting a projection window size by the user. The first electronic device receives the second operation indication sent by the second electronic device, and sends third projection data of the first application to the second electronic device based on the second operation indication. Correspondingly, the second electronic device receives the third projection data, and displays, in the first application running mode based on the third projection data, the first application in the projection window whose window size is adjusted.
For example, in the scenario shown in
In this case, after detecting an operation of adjusting a size of the projection window 61 by the user, the second electronic device may generate a corresponding window size adjustment event, and send, to the first electronic device, a second operation indication carrying the window size adjustment event. As shown in
In this way, the second electronic device can display, based on the third projection data, a new first application interface in the projection window 61 whose window size is adjusted.
In some other embodiments, when the first application running mode is not the computer application running mode, in response to an operation of adjusting a projection window size by the user, the second electronic device proportionally zooms in or out and displays the projection window and a projection interface of the first application in the projection window.
For example, in the scenario shown in
In this case, after the second electronic device detects an operation of adjusting a size of the projection window 71 by the user, as shown in
In this way, the projection window is adjusted, so that projection of the second electronic device 200 can better meet a use habit of the user, and user experience is further improved.
Optionally, the first electronic device may further perform steps and functions performed by the first electronic device 100 or the mobile phone in the foregoing embodiments, and the second electronic device may further perform steps and functions performed by the second electronic device 200 or the computer in the foregoing embodiments, to implement the scenario configuration method provided in the foregoing embodiments.
