TECHNICAL FIELD

This application relates to the field of terminal technologies, and in particular, to a split-screen display method and apparatus.

BACKGROUND

Currently, when using an electronic device (for example, a mobile phone or a tablet computer), a user may switch frequently between two application programs.

When switching between applications, the user usually needs to exit from a current application and then enter another application from a home screen. This operation is very complicated and user experience is poor.

SUMMARY

Embodiments of this application provide a split-screen display method and apparatus. A problem in which a user needs to perform frequent operations for application switching can be resolved and user experience may be improved.

According to a first aspect, some embodiments of this application provide a split-screen display method, including: An electronic device displays a first interface of a first application in full screen at a first moment. The electronic device displays split-screen prompt information in the first interface of the first application when a first preset condition is satisfied, where the split-screen prompt information includes an application icon of the first application and an application icon of a second application: in the split-screen prompt information, the application icon of the first application is located on a left side, an upper side, or an upper left side of the application icon of the second application: a preset graphic and/or preset text are included in the split-screen prompt information: the preset graphic includes a vertical line or an ellipse: the preset text includes “enter split-screen mode” or “split screen”: the split-screen prompt information is for prompting split-screen display to be performed on the first application and the second application: the first application is an application running at foreground; and the second application is an application that is recommended by the electronic device and that is for split-screen display performed on the first application. The electronic device displays a split-screen interface in response to an operation by a user based on the split-screen prompt information, where the split-screen interface includes the first interface of the first application and a second interface of the second application.

DESCRIPTION OF EMBODIMENTS

Currently, when using an electronic device (for example, a mobile phone or a tablet computer), a user may simultaneously open a plurality of application programs and switch between two application programs. For example, the user may reply a short message service message in Messages application while writing a memo in Memo application. When switching between applications, the user usually needs to exit from a current application and then enter another application from a home screen. This operation is very complicated and user experience is poor.

To better meet a requirement of the user, a split-screen function may be provided to the user. In other words, a plurality of (for example, two) applications are simultaneously displayed on a screen, and two applications simultaneously run without affecting each other, thereby preventing the user from switching between the applications back and forth. In conventional technologies, the user needs to perform complex operations to trigger the electronic device to enter a split-screen mode. For example, when the electronic device displays an interface of application A in full screen, the user may touch and hold a task key to enter the split-screen mode (or slide up from a bottom of a mobile phone and stay to enter an interface of a background application widget, and then tap a split-screen icon to enter the split-screen mode), and then the user manually selects another application on which split-screen display needs to be performed. For example, by taping an icon of application B, application A and application B are finally displayed in different windows respectively.

Therefore, in conventional technologies, the user needs to select an application on which screen splitting is to be performed, and needs to perform complex operations to complete a split-screen operation to enable the electronic device to enter a split-screen mode. User experience is not good.

Embodiments of this application provide a split-screen display method and apparatus. When it is detected that switching is frequently performed between a current application (an application running at foreground) and another application, a split-screen prompt may be triggered. Split-screen display may be triggered in response to an operation performed by the user on the split-screen prompt. In this way, complicated operations performed manually by the user is avoided and user experience may be improved.

The split-screen display method provided in embodiments of this application may be applied to an electronic device. For example, the electronic device may be a mobile phone (including a foldable screen phone and a bar-type mobile phone), a tablet computer, a desktop (a desktop computer), a handheld computer, a notebook computer (a laptop computer), an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook, a personal digital assistant (personal digital assistant, PDA), an augmented reality (augmented reality, AR)\virtual reality (virtual reality, VR) device, or the like.

For ease of understanding, the split-screen display method provided in embodiments of this application is described below in detail with reference to the accompanying drawings.

As shown in FIG. 3, embodiments of this application provide a split-screen display method and an example in which an electronic device is a foldable screen phone is used for description. The method includes the following steps.

301. A service logic processing module subscribes for an application switching fence to a context awareness module.

After the service logic processing module subscribes the application switching fence to the context awareness module, and when the context awareness module detects that a user opens an application or switches between applications, the service logic processing module may be notified.

302. The context awareness module detects an operation that an application is switched by the user, and notifies the service logic processing module that application switching occurs.

When the user performs the application switching, the context awareness module may sense the operation that the application is switched by the user, trigger the application switching fence, and send an application switching fence triggering notification to the service logic processing module. The application switching fence triggering notification indicates that the application switching occurs.

For example, at a first moment, as shown in FIG. 4A(1), the mobile phone may display an interface 401 of Memo. Memo is an APP running at foreground at this time. At a second moment (later than the first moment), the user may switch to Messages application, as shown in FIG. 4A(2), and the mobile phone may display an interface 402 of Messages application (Information application). In this case, Messages application is an APP running at foreground. When detecting that the user opens/switches to Messages application, the context awareness module may send an application switching notification (the application switching fence triggering notification) to the service logic processing module. The application switching notification may carry application information of a current application (an application currently running at foreground, such Messages application). The application information includes a package name and a task identification (task identification, task ID). The package name indicates which application the information belongs to, such as Information application or Memo application. The task identification task ID indicates a current displayed interface. Optionally, the application switching notification may also carry time information to open the current application and the like. This is not limited in this application.

303. The service logic processing module determines whether applications between which switching is frequently performed exist.

Each time receiving the application switching notification from the context awareness module, the service logic processing module may read the application information of the current application (the package name and the task ID) from the application switching notification. The current application information is added to a recently used application list based on the application information of the current application. The recently used application list may be determined based on a sliding time window statistical algorithm. For example, the recently used application list may be shown in Table 1.

TABLE 1
Time                   Application identification (package name)
2021-11-10 at 11:00:00 Package name of application A (for example,
                       com.android.mms)
2021-11-10 at 11:05:00 Package name of application B (for example,
                       com.android.memo)
2021-11-10 at 11:20:00 Package name of application A
2021-11-10 at 11:25:00 Package name of application B
2021-11-10 at 11:36:00 Package name of application A

It can be learned from Table 1 that the user enters (opens) application A on 2021 Nov. 10 at 11:00:00, enters application B on 2021 Nov. 10 at 11:05:00, enters application A again on 2021 Nov. 10 at 11:20:00, enters application B again on 2021 Nov. 10 at 11:25:00, and enters application A again on 2021 Nov. 10 at 11:36:00.

A maximum quantity of application information included in the recently used application list may be N (N is a preset positive integer, for example, N=5). When a quantity of application information included in the recently used application list is N (for example, five), it is determined whether the applications on which switching is frequently performed exist in the recently used application list.

In a possible design, it may be counted whether occurring frequency of the application information of the current application (a latest application information added to the application list) and occurring frequency of another application information in the recently used application list are greater than or equal to a first preset threshold (for example, twice). If the occurring frequency of the application information of the current application (for example, application A) and occurring frequency of the application information of another application (for example, application B) are both greater than or equal to the first preset threshold, it is considered that switching is frequently performed between the current application (for example, application A) and the another application (for example, application B).

For example, it is assumed that in five recently used applications, frequency of switching between the current application and the another application back and forth is more than twice. For example, a switching order is application A to application B to application A to application B to application A. It is considered that the switching is frequently performed between the current application (for example, application A) and the another application (for example, application B).

In some embodiments, the service logic processing module may only add application information that is displayed in full screen in last M minutes (for example, five minutes) to the recently used application list. Optionally, duration of full-screen display of an application in the recently used application list may be T seconds (for example, 60 seconds). Application information of an application opened via a floating window (via a small window) may not be added to the recently used application list, and therefore, may not participate in the determining of applications between which switching is frequently performed. Optionally, the application information of Setting application and Home Screen application may also not be added to the recently used application list, and therefore may not participate in the determining of applications between which switching is frequently performed.

In addition, the application information of Home Screen application and Setting application may not be added to the recently used application list, and therefore, may not participate in the determining of applications between which switching is frequently performed. In other words, Home Screen application or Setting application may be removed from an application switching sequence.

In another possible design, if it is determined that the user switches between two applications in full screen (for example, application A and application B) for Y times (where switching from application A to application B counts as one switching, and switching from application B to application A also counts as one switching) within X seconds (for example, 100 seconds, 200 seconds, and 300 seconds), it is considered that the switching is frequently performed between application A and application B. X and Y are configurable system service parameters, for example, X=300 and Y=4.

304. The service logic processing module determines whether to perform split-screen display on two applications between which switching is frequently performed.

The service logic processing module may determine the following two points.

• • (1) Whether a current screen supports a screen splitting function is determined.

The service logic processing module may call the multi-window management module to determine whether the current screen supports the screen splitting function. In addition, the service logic processing module may register a callback with the multi-window management module. A function of registering the callback is to return a result of whether the current screen supports the screen splitting function to the service logic processing module after the multi-window management module determines whether the current screen supports the screen splitting function.

As shown in FIG. 4B, the multi-window management module may obtain a height grid quantity and a width grid quantity of a screen of the electronic device. When the height grid quantity and the width grid quantity both are eight, it may be determined that the electronic device is a foldable-screen device (a foldable screen phone). A screen size of the foldable screen phone may be 7 to 8 inches. When the height grid quantity and the width grid quantity are 8 and 12 respectively, it may be determined that the electronic device is a tablet computer, and a screen size of the tablet computer may be 8 to 11 inches. If the electronic device is the foldable-screen device or the tablet computer, it is determined that the screen of the electronic device supports the screen splitting function.

Certainly, another type of device also supports the screen splitting function. For example, a bar-type mobile phone also supports the screen splitting function.

• • (2) Whether two applications (for example, application A and application B) between which switching is frequently performed support screen splitting function (by transmitting package names).

The service logic processing module may call the multi-window management module to determine whether an application (for example, application A and application B) supports the screen splitting function. In addition, the service logic processing module may register a callback with the multi-window management module. A function of registering the callback is to return a result of whether the application supports the screen splitting function to the service logic processing module after the multi-window management module determines whether the application supports the screen splitting function.

The multi-window management module may maintain a white list of an application list. The white list of the application list may include an identification of an application (for example, a package name of the application) that supports the screen splitting function. For example, the white list of the application list that supports the screen splitting function may be shown in Table 2.

TABLE 2
                                 Support a screen splitting
Application identification (package name) function or not
Package name of application A (for example, Yes
com.android.mms)
Package name of application B (for example, Yes
com.android.memo)
Package name of application C    Yes
Package name of application D    Yes
Package name of application E    Yes

The multi-window management module may query whether the white list of the application list includes the two applications (for example, application A and application B) between which switching is frequently performed. If the white list of the application list includes the two applications between which switching is frequently performed, it is determined that the two applications between which switching is frequently performed support the screen splitting function.

If the current screen supports the screen splitting function and both the two applications between which switching is frequently performed support the screen splitting function, step 305 may be performed.

If the current screen does not support the screen splitting function and/or either of the two applications between which switching is frequently performed does not support the screen splitting function, step 305 is not performed and a process is stopped.

305. The service logic processing module sends a split-screen instruction to the service presentation module.

The split-screen instruction may include application information of the two applications between which switching is frequently performed and display position information (split-screen display position information) respectively corresponding to the two applications that are displayed in split screen and between which switching is frequently performed.

The service logic processing module determines a type of split-screen display based on a capability of the current screen. The type of split-screen display may include vertical split-screen display and horizontal split-screen display. After the type of split-screen display is determined, position information (split-screen display position information) respectively corresponding to the two applications in split screen display and between which switching is frequently performed may be determined. When the type of split-screen display is the vertical split-screen display, the service logic processing module may default that a current application (for example, application A) is displayed on a left side and another application (for example, application B) is displayed on a right side. In this way, user's gaze may be focused on a left side area, and visual consistency of the user may be met. When the type of split-screen display is the horizontal split-screen display, the service logic processing module may default that a current application (for example, application A) is displayed on an upper side and another application (for example, application B) is displayed on a lower side. In this way, user's gaze may be focused on an upper side area, and visual consistency of the user may be met.

In a possible design, the service logic processing module may adjust a display position of an application in split-screen display based on a habit of the user. For example, if it is detected that the user is used to placing application B on a left or a top split screen in the split-screen display, application B may be displayed on the left or the top split screen and the current application (for example, application A) is displayed on a right or a top side. Alternatively, if it is detected that the user is used to placing application A on a right (or is used to operating application A by using the right hand) or a lower split screen in the split-screen display, an application (for example, application A) may be displayed on the right or the top side and application B is displayed on a left or a top side.

306. The service presentation module displays a floating capsule.

The service presentation module receives the split-screen instruction from the service logic processing module, and then may display the floating capsule. The floating capsule is for prompting the user to perform split-screen display. The floating capsule (a split-screen floating capsule) may also be referred to as a floating icon (a split-screen floating icon), a floating window (a split-screen floating window), a floating ball (a split-screen floating ball), or a floating notification (a split-screen floating notification). This is not limited in this application.

Display content of the floating capsule may be determined based on information carried in the split-screen instruction. In some embodiments, if the split-screen display position information carried in the split-screen instruction indicates that the current application (for example, application A) is displayed on the left side and another application (for example, application B) is displayed on the right side, the display content of the floating capsule may include an application icon of application A and an application icon of application B, and the application icon of application A is on the left and the application icon of application B is on the right. The application icon of application A and the application icon of application B are separated by a vertical line or separated by text “enter split-screen”.

As shown in FIG. 5A, if a current application is Messages application, the mobile phone may display a floating capsule 403 on an interface 402 of Messages application. The floating capsule 403 includes an application icon 403a of Messages and an application icon 403b of Memo (an application in which switching is frequently performed between the application and Messages application). The application icon 403a of Messages and the application icon 403b of Memo are separated by a vertical line 403c. The floating capsule 403 is for prompting the user to perform split-screen display on Messages application and Memo application. The application icon 403a of Messages application (the current application) is displayed on a left side of the floating capsule 403, and the application icon 403b of Memo application (an application in which switching is frequently performed between the application and the current application) is displayed on a right side of the floating capsule 403.

Alternatively, as shown in FIG. 5B, if the current application is Messages application, the mobile phone may display a floating capsule 404 on an interface 402 of Messages application. The floating capsule 404 includes an application icon 404a of Messages and an application icon 404b of Memo (an application in which switching is frequently performed between the application and Messages application). The application icon 404a of Messages and the application icon 404b of Memo are separated by text 404c “enter split-screen”, to intuitively prompt the user to enable a split-screen function. The application icon 404a of Messages application (the current application) is displayed on a left side of the floating capsule 404, and the application icon 404b of Memo application (an application in which switching is frequently performed between the application and the current application) is displayed on a right side of the floating capsule 404.

The display content of the floating capsule may alternatively be in another form. For example, as shown in (a) in FIG. 6, a circular bubble 602 may be displayed on a left side area of a floating capsule 601. The circular bubble 602 may displays an application icon 603 of Messages (a current application) and an application icon 604 of Memo (an application in which switching is frequently performed between the application and the current application) in a staggered manner. The application icon 603 of Messages application may be displayed on an upper left side of the application icon 604 of Memo application (the application icon 604 of Memo application may be displayed on a lower right side of the application icon 603 of Messages application). Prompt text “enter split-screen” 605 may be displayed on a right side of the floating capsule 601.

For another example, as shown in (b) in FIG. 6, a left side of a floating capsule 610 may display only an application icon 611 of Memo (an application in which switching is frequently performed between the application and a current application), and prompt words “enter split-screen” 612 may be displayed a right side of the floating capsule 610 to prompt the user to perform split-screen display on Messages (the current application) and Memo (the application in which switching is frequently performed between the application and the current application).

It should be noted that, a display position of the floating capsule on a screen may be floated on a side (an upper side, a lower side, a left side, or a right side) of a full-screen window of the current application, displayed on a side dock, displayed upper side of a floating ball, or placed on a lower side of a banner notification, a notification card, a notification center, a floating navigation button, or the like. This is not limited in this application.

For example, as shown in FIG. 7A(1), the mobile phone may display a floating capsule 403 on an upper side of an interface 402 of a current application. For the display content of the floating capsule, refer to related descriptions in FIG. 5A. Details are not described herein again. For another example, as shown in FIG. 7A(2), the mobile phone may display a floating capsule 404 on an upper side of an interface 402 of a current application. For the display content of the floating capsule, refer to related descriptions in FIG. 5B. Details are not described herein again.

In a possible design, only after the user enters the current application and stays for preset duration (for example, three seconds), display of the floating capsule is triggered. For example, as shown in FIG. 5A, only when the user opens Messages application and stays for at least three seconds, the mobile phone displays the floating capsule 403.

In a possible design, split-screen prompt information is displayed on the currently displayed first interface of the first application in an overlay manner when a second application and a third application are included in a first quantity of consecutive applications, occurring frequency of the first application and occurring frequency of the second application are both greater than or equal to first frequency, and switching frequency between the second application and the first application is greater than or equal to second frequency, where the first quantity of consecutive applications are a first quantity of consecutive applications displayed in full screen within first time before the first moment, and the first quantity of consecutive applications include the first application. For example, the first time may be five minutes, the first frequency may be twice, the second frequency may be twice, and the first quantity may be five.

For example, it is assumed that in five recently used applications, a switching order is application A (the first application) to application B (the second application) to application C (the third application) to application A to application B. Alternatively, a switching order is application A to application C to application B to application A to application B. It is considered that switching is frequently performed between the first application (application A) and the second application (application B), and the split-screen prompt information is displayed in the overlay manner on the currently displayed first interface of the first application.

In another possible design, the electronic device displays a first interface of the first application in full screen at the first moment, displays an interface of the second application in full screen at a second moment after the first moment in response to switching from the first application to the second application, displays an interface of the third application in full screen at a third moment after the second moment in response to switching from the second application to the third application, displays the interface of the second application in full screen at a fourth moment after the third moment in response to switching from the third application to the second application, displays an interface of the first application in full screen at a fifth moment after the fourth moment in response to switching from the second application to the first application, and displays the split-screen prompt information in an overlay manner on the first application interface displayed at the fifth moment when a difference between the fifth moment and the first moment is less than or equal to the first time, and the first application, the second application, and a current screen all support a screen splitting function.

For example, as shown in FIG. 7B(1), it is assumed that at moment t1, the mobile phone displays an interface 401 of Memo application in full screen. Then, at moment t2 after the interface of Memo application is displayed, as shown in FIG. 7B(2), the user switches from Memo application to Information application, and a mobile phone screen displays an interface 402 of Information application in full screen. Next, at moment t3 after the interface 402 of the information application is displayed in full screen, as shown in FIG. 7B(3), the user switches from the information application to a camera application, and the electronic device screen displays an interface 403 of the camera application in full screen. Then, at moment t4 after the interface of Camera application is displayed in full screen, as shown in FIG. 7B(4), the user switches from the camera application to Memo application, and the electronic device screen displays an interface 404 of Memo application in full screen. Then, at moment t5 after moment t4, as shown in FIG. 7B(5), the user switches from Memo application to Information application, and the electronic device screen displays an interface 405 of Information application in full screen. In addition, at moment t5, if the electronic device determines that a difference between moment t5 and moment t1 is less than or equal to the first time, Information application, Memo application and Camera application are not applications in a preset blacklist, both Information application and Memo application support a screen splitting function, and the electronic device also supports the screen splitting function, the electronic device determines that Information application and Memo application are applications between which switching is frequently performed, so that the electronic device displays the floating capsule in the overlay manner on the interface of Information application displayed at moment t5.

In embodiments of this application, the electronic device immediately performs a split screen prediction at moment t5, and when it is predicted that a split-screen operation needs to be performed, the floating capsule is immediately displayed on the interface of Memo application that is displayed in full screen at moment t5. In this way, the user may quickly enter a split-screen status by using an operation on the floating capsule.

In embodiments of this application, the user does not need to consider whether to perform a split-screen operation in advance, and does not need to pre-configure the split screen status. This not only saves energy and time for the user, but also reduces an operation step by the user, so that the screen splitting function of the electronic device may be easily and conveniently used by the user.

In an example, the first time may be five minutes. Certainly, in embodiments of this application, a specific value of the first time is not limited, and the specific value of the first time may be adjusted based on a usage requirement.

In still another possible design, the electronic device displays a first interface of the first application in full screen at the first moment, displays an interface of the second application in full screen at a second moment after the first moment in response to switching from the first application to the second application, displays an interface of a third application in full screen at a third moment after the second moment in response to switching from the second application to the third application, displays the interface of the second application in full screen at a fourth moment after the third moment in response to switching from the third application to the second application, displays an interface of the first application in full screen at a fifth moment after the fourth moment in response to switching from the second application to the first application, detects that the interface of the first application maintains a full screen displayed state at a sixth moment after the fifth moment, and displays the split-screen prompt information in an overlay manner on the first application interface displayed at the sixth moment when a difference between the sixth moment and the first moment is less than or equal to a first time, and the first application, the second application, and a current screen all support a screen splitting function.

Refer to FIG. 7B(5). After an interface 405 of an information application is displayed, after target time, for example, the target time may be three seconds, at moment t6 after moment t5 (where an interval between moment t5 and moment t6 is the three seconds), if the interface of the information application shown in FIG. 7B(5) still maintains the full screen displayed state at this time, the electronic device enables a split-screen prediction. To be specific, at moment t6, if the electronic device determines that a difference between moment t6 and moment t1 is less than or equal to the first time, Information application, Memo application, and Camera application are not applications in a preset blacklist, Information application and Memo application support a screen splitting function, and the electronic device also supports the screen splitting function, the electronic device determines that Information application and Memo application are applications between which switching is frequently performed, so that the electronic device displays the floating capsule in the overlay manner on the interface of Memo application displayed at moment t6.

The blacklist may include an application that is infrequently used by the user such as Setting application, and an application that the user needs to use in a process of switching between applications, such as Home Screen application. The application in the blacklist may be pre-configured. Based on a usage habit or purpose of the user, it is determined that the application in the blacklist is an application on which a split-screen operation does not need to be performed. By removing the application from applications on which the split-screen operation needs to be performed, the electronic device may accurately determine split-screen timing, so that the electronic device can recommend the split-screen operation for the user when the user really needs to perform the split-screen operation and user experience is improved. t1<t2<t3<t4<t5<t6.

In embodiments of this application, the electronic device does not perform the split-screen prediction immediately at moment t5, but waits for a period of time (the target time) and then performs the split-screen prediction when detecting that Memo application maintains the full-screen display state. In this way, it may be ensured that the switching to a current application (in this example, Memo application) is a true intention of the user and not an unintentional operation of the user, thereby performing an accurate split-screen prediction. In embodiments of this application, the floating capsule is displayed on the interface of Information application displayed in full screen at moment t6, when it is predicted that the split-screen operation needs to be performed. In this way, the user may quickly enter a split-screen status by using an operation on the floating capsule.

In some cases, due to a touch error or another reason, the user may switch to an application interface by mistake, and then often exit the application interface quickly. Switching in this case is not the true intention of the user. If a split-screen recommendation is triggered in this case, the split screen recommendation may be made at inappropriate timing, bringing poor experience to the user. In embodiments of this application, by waiting for the target time and then performing the split-screen prediction, misunderstanding intention of the user to switch between applications may be avoided and an accurate split-screen prediction is performed.

307. The service presentation module monitors a taping event.

After displaying the floating capsule, the service presentation module may monitor the taping event. If a floating capsule taping event occurs within preset duration (for example, five seconds) for displaying the floating capsule, the split-screen operation is triggered. In other words, steps 308 and 309 are performed.

If it is detected that the user does not tap the floating capsule within the preset duration, the floating capsule may be automatically closed (the floating capsule automatically disappears) to avoid affecting user experience of using an application. Certainly, the user may also manually close the floating capsule by using a preset gesture (for example, a drag and drop gesture or a slide gesture).

In addition, the floating capsule may also disappear automatically when the user exits a current page, or disappear naturally when the user taps the floating capsule to enter a split-screen mode.

308. The service presentation module notifies the multi-window management module to perform split-screen display in response to detecting that the user taps the floating capsule.

The service presentation module may call a system split-screen capability, to be specific, send split-screen notification information to the multi-window management module. The split-screen notification information notifies the multi-window management module to perform the split-screen operation on two applications (for example, application A and application B) between which switching is frequently performed. The split-screen notification information may carry package names or task IDs of the two applications (for example, application A and application B) between which switching is frequently performed.

309. The multi-window management module displays the two applications in split screen between which switching is frequently performed.

After receiving the split-screen notification information, the multi-window management module may simultaneously open an activity corresponding to an interface (the first interface) that the user recently browsed in application A and an activity corresponding to an interface (the second interface) that the user recently browsed in application B (open application A and application B). In this way, display interfaces of application A and application B may be displayed on a display interface simultaneously, to implement one-tap splitting.

As shown in FIG. 8A, in response to an operation that a floating capsule 403 is tapped by the user on an interface 402 of Messages application, as shown in FIG. 8B, the mobile phone may perform split-screen display on Messages application (a current application) and Memo application (an application in which switching is frequently performed between the application and the current application). The interface 420 of Messages application (the current application) may be displayed on a left side of a mobile phone screen, and an interface 421 of Memo application (the application in which switching is frequently performed between the application and the current application) may be displayed a right side of the mobile phone screen. The interface 420 of Messages application and the interface 421 of Memo application may be separated by a splitting bar 422. Respective display positions of the interface 420 of Messages application and the interface 421 of Memo application on the mobile phone screen correspond to positions of an application icon of Messages application and an application icon of Memo application in the floating capsule. In other words, when the application icon of Messages application in the floating capsule is on a left side, the interface of Messages application is displayed on the left side of the mobile phone screen when split-screen display is performed. When the application icon of Memo application in the floating capsule is on a right side, the interface of Memo application is displayed on the right side of the mobile phone screen when split-screen display is performed.

The foldable screen phone is used as an example for description in the foregoing. When the user uses a bar-type mobile phone (or a foldable screen phone with a horizontal splitting screen), because a width of the bar-type mobile phone (or the foldable screen phone with a horizontal splitting screen) is short, user experience is poor in a case of vertical screen splitting. Therefore, for the bar-type mobile phone, a horizontal split-screen manner is used. For example, as shown in FIG. 9A and FIG. 9B, it is detected that the user switches frequently between an interface 901 of Memo application and an interface 902 of Messages application. As shown in FIG. 9C, when the mobile phone displays the interface 902 of Messages application, a floating capsule 903 may be displayed. In the floating capsule 903, an application icon of Messages application (a current application) is on an upper side, and an application icon of Memo application (an application in which switching is frequently performed between the application and the current application) is on a lower side. The application icons of Messages application and Memo application are separated by a horizontal line (or may be separated by text “enter split-screen”). As shown in FIG. 9D, in response to an operation that the floating capsule 903 is tapped by the user, the mobile phone may perform split-screen display on Messages application (a current application) and Memo application (an application in which switching is frequently performed between the application and the current application). An interface 904 of Messages application (the current application) may be displayed on an upper side of a mobile phone screen, and an interface 905 of Memo application (the application in which switching is frequently performed between the application and the current application) may be displayed on a lower side of the mobile phone screen. The interface 904 of Messages application and the interface 905 of Memo application may be separated by a splitting bar 906. Respective display positions of the interface 904 of Messages application and the interface 905 of Memo application on the mobile phone screen correspond to positions of an application icon of Messages application and an application icon of Memo application in the floating capsule. In other words, when the application icon of Messages application in the floating capsule is on the upper side, the interface of Messages application is displayed on the upper side of the mobile phone screen when split-screen display is performed. When the application icon of Memo application in the floating capsule is on the lower side, the interface of Memo application is displayed on the lower side of the mobile phone screen when split-screen display is performed.

Embodiments of this application further provide a chip system. As shown in FIG. 10, the chip system includes at least one processor 1001 and at least one interface circuit 1002. The processor 1001 and the interface circuit 1002 may be connected to each other by using a line. For example, the interface circuit 1002 may be configured to receive a signal from another apparatus (such as a memory of an electronic device). In another example, the interface circuit 1002 may be configured to send a signal to another apparatus (for example, the processor 1001).

For example, the interface circuit 1002 may read instructions stored in the memory of the electronic device and send the instructions to the processor 1001. When the instructions are executed by the processor 1001, the electronic device (the mobile phone 100 shown in FIG. 1) may be enabled to perform the steps in the foregoing embodiments.
