The present disclosure generally relates to the field of terminal technology and, more particularly, to a method and a terminal for responding to a sliding operation.
For program windows of a touch-screen terminal, performing a sliding operation, e.g., by sliding a finger upward or downward, has become a standard operation mode for scrolling a screen.
Conventionally, an operating system of the touch-screen terminal, such as an Android operating system, may include a system process, an application process, and an interface delivery process. When responding to a sliding operation, interactions among the system process, the application process and the interface delivery process include that the system process receives the sliding operation and transmits a message of the sliding operation to the corresponding application process. The application process draws window contents according to the message of the sliding operation, and transmits the drawn window contents to the interface delivery process. Then the interface delivery process triggers to refresh the screen, and outputs the window contents onto the screen.
The above method generally takes a relatively long time from when the system access acquires the sliding operation to when processing results corresponding to the sliding operation are output onto the screen, which results in a delay in displaying the window contents onto the screen.
According to a first aspect of the present disclosure, there is provided a method for responding to a sliding operation for use in a terminal having a touch screen and operating on an operating system including a system process, an application process, and an interface delivery process, wherein the application process is configured to draw a display content in a size larger than a size of the touch screen, the method comprising: when the system process detects the sliding operation, acquiring a sliding distance and a sliding direction of the sliding operation; transmitting, by the system process, the sliding distance and the sliding direction of the sliding operation to each of the application process and the interface delivery process; when the interface delivery process receives the sliding distance and the sliding direction, moving a display window in the sliding direction, according to the sliding distance; and controlling, by the interface delivery process, the touch screen to display a display content corresponding to the moved display window.
According to a second aspect of the present disclosure, there is provided a terminal for responding to a sliding operation, comprising: a processor; a touch screen coupled to the processor; and a memory for storing an operating system including a system process, an application process, and an interface delivery process, wherein: the application process is configured to draw a display content in a size larger than a size of the touch screen; the system process, when detecting the sliding operation, acquires a sliding distance and a sliding direction of the sliding operation; the system process transmits the sliding distance and the sliding direction of the sliding operation to each of the application process and the interface delivery process; the interface delivery process, when receiving the sliding distance and the sliding direction, moves a display window in the sliding direction, according to the sliding distance; and the interface delivery process controls the touch screen to display a display content corresponding to the moved display window.
According to a third aspect of the present disclosure, there is provided a non-transitory storage medium having stored therein instructions regarding an operating system that, when executed by a processor of a terminal, cause the terminal to perform a method for responding to a sliding operation, the terminal having a touch screen, and the operating system including a system process, an application process, and an interface delivery process, wherein the application process is configured to draw a display content in a size larger than a size of the touch screen, the method comprising: when the system process detects the sliding operation, acquiring a sliding distance and a sliding direction of the sliding operation; transmitting, by the system process, the sliding distance and the sliding direction of the sliding operation to each of the application process and the interface delivery process; when the interface delivery process receives the sliding distance and the sliding direction, moving a display window in the sliding direction, according to the sliding distance; and controlling, by the interface delivery process, the touch screen to display a display content corresponding to the moved display window.
It is to be understood that both the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present invention.
The accompanying drawings, which are hereby incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the invention as recited in the appended claims.
In step 101, when the system process detects the sliding operation, a sliding distance and a sliding direction of the sliding operation are acquired.
In step 102, the system process transmits the sliding distance and the sliding direction of the sliding operation to each of the application process and the interface delivery process.
In step 103, when the interface delivery process receives the sliding distance and the sliding direction, a display window is moved in the sliding direction, according to the sliding distance.
In step 104, the interface delivery process controls the touch screen to display a display content corresponding to the moved display window.
In the method 100, the application process draws the display content in a size larger than the size of the touch screen. When the system process detects the sliding operation, the system process transmits related data of the sliding operation to the application process and the interface delivery process, triggers the interface delivery process to move a display window on the drawn display content, so as to control the touch screen to display the display content indicated by the sliding operation. Thus, the time that the interface delivery process waits for the application process to draw is reduced, and a response speed of the sliding operation is increased, such that synchronization of screen display and the sliding operation is enhanced.
In one exemplary embodiment, when the application process determines that a display content indicated by the sliding distance exceeds the display content drawn by the application process, the application process drawing an excess portion of the display content indicated by the sliding distance according to the sliding distance and the display content. In one exemplary embodiment, the application process draws the excess portion of the display content by generating the excess portion in the memory. The application process transmits the excess portion to the interface delivery process. Correspondingly, when the interface delivery process receives the excess portion, the interface delivery process controls the touch screen to display the display content corresponding to the display window that has been moved and the excess portion.
In one exemplary embodiment, when the application process transmits the excess portion to the interface delivery process, the application process transmits a position identification of the excess portion to the interface delivery process. Correspondingly, the interface delivery process controls the touch screen to display the display content corresponding to the display window that has been moved and the excess portion, according to the position identification of the excess portion.
In one exemplary embodiment, when the interface delivery process receives the sliding distance and the sliding direction, the interface delivery process moves the display window by the sliding distance in the sliding direction.
In step 201, when an application of the terminal is started, the application process draws a display content. For example, the application process draws the display content by generating the display content in a memory.
In exemplary embodiments, each application process serves for one application, and the application process is configured to draw a display content of the application corresponding to the application process. The display content is displayed on an interface of the application. The display content of the application includes, but is not limited to, a background of the application and various objects of the application and the like. For a desktop when the terminal is started, the operating system of the terminal also has an application process that serves for the desktop in order to draw the desktop.
In exemplary embodiments, a size of the display content is larger than a size of the touch screen, and the size of the display content may be a preset multiple of the size of the touch screen. The preset multiple may also be adjusted during use. For example, the preset multiple may be 1.2 times, to avoid a large size of the display content occupying too much space of a memory of the terminal.
In step 202, the application process transmits the drawn display content to the interface delivery process.
In the present disclosure, the interface delivery process is configured to display received display content, and move a display window on the drawn display content, to control the display content on the touch screen. The display window is configured to identify the display content on the touch screen, that is, a content corresponding to the display window is the display content on the touch screen.
In one exemplary embodiment, when the application process transmits the drawn display content to the interface delivery process, the application process may also simultaneously transmit a position identification of the drawn display content to the interface delivery process. The position identification may be coordinates. For example, the position identification of the display content is (1, 10)˜(1, 60).
In step 203, when the interface delivery process receives the display content, the interface delivery process controls the touch screen to display the display content corresponding to the display window.
In the present embodiment, since the size of the display content is larger than the size of the touch screen, the touch screen may display a portion of the display content. When the interface delivery process receives the display content, the interface delivery process controls the touch screen to display the content which corresponds to the display window and is to be displayed when the terminal is initially started. In one exemplary embodiment, the position identification of the display content is (1, 10)˜(1, 60), a position identification of the content that is to be displayed when the terminal is initially started is (1, 10)˜(1, 50), and the interface delivery process controls the touch screen to display the content corresponding to the display window and having the position identification of (1, 10)˜(1, 50).
In step 204, when the system process detects a sliding operation, the system process acquires a sliding distance and a sliding direction of the sliding operation.
The system process is configured to transmit related data of the sliding operation to the application process and the interface delivery process, when the system process detects the sliding operation.
The sliding operation may be a sliding operation on an operating interface of the application. For example, when a picture is displayed, the sliding operation is an operation of dragging the picture in a certain direction by a user through the operating interface, or when a web content is displayed using a browser, the sliding operation may also be an operation of dragging the web content in a certain direction by a user through an operating interface.
In the present embodiment, when the system process detects the sliding operation, the system process may acquire the sliding distance and the sliding direction of the sliding operation according to a trajectory character input by a gesture of the sliding operation.
In the present embodiment, when the system process detects the sliding operation, the sliding distance and the sliding direction of the sliding operation are acquired. In another embodiment, when the system process detects that a direction control button is triggered, a distance and a direction corresponding to the direction control button are acquired. While the direction control button is configured to control the display content of the touch screen to move a preset distance in a preset direction, the embodiment of the present disclosure does not limit the preset direction and a value of the preset distance.
In step 205, the system process transmits the sliding distance and the sliding direction of the sliding operation to each of the application process and the interface delivery process, so that when the interface delivery process receives the sliding distance and the sliding direction of the sliding operation, the interface delivery process controls the touch screen to display a display content indicated by the sliding distance, without waiting for the application process to transmit the display content drawn by the application process, thus a response speed of the sliding operation is increased.
In step 206, when the interface delivery process receives the sliding distance and the sliding direction, the display window is moved in the sliding direction, according to the sliding distance.
In one exemplary embodiment, when the display content indicated by the sliding distance does not exceed the display content drawn by the application process, the display content that has been drawn by the application process may satisfy a current display requirement of the sliding operation. When the interface delivery process receives the sliding distance and the sliding direction, the display window is moved by the sliding distance in the sliding direction. For example, when the sliding distance of the sliding operation is 1 cm, and the sliding direction is in a horizontal-left direction, the interface delivery process moves the display window by 1 cm in the horizontal-left direction.
In one exemplary embodiment, when the display content indicated by the sliding distance exceeds the display content drawn by the application process, the display content drawn by the application process may not satisfy the current display requirement of the sliding operation. Thus, the application process receives the sliding distance and the sliding direction, and determines that the display content indicated by the sliding distance exceeds the display content drawn by the application process. The application process draws an excess portion of the display content indicated by the sliding distance according to the sliding distance and the display content, and transmits the excess portion and a position identification of the excess portion to the interface delivery process. In one exemplary embodiment, the application process draws the excess portion of the display content by generating the excess portion in the memory. When the application process receives the excess portion and the position identification of the excess portion, the display window is moved by the sliding distance in the sliding direction, so that the display window that has been moved corresponds to the display content and the excess portion. At this time, the interface delivery process displays a portion of the drawn display content together with the excess portion. The portion of the drawn display content may be displayed firstly and, then, the excess portion, when being received, is displayed based on the portion of the drawn display content being displayed. Thus, the response speed is increased to ensure a display effect.
For example, the position identification of the display content drawn by the application process is (1, 50)˜(1, 60), and the position identification of the display content indicated by the sliding distance is (1, 50)˜(1, 100). Thus, the content having the position identification of (1, 60)˜(1, 100) is the excess portion. When the interface delivery process receives the content having the position identification of (1, 60)˜(1, 100) of the excess portion, the display window is moved by the sliding distance in the sliding direction, such that the display window that has been moved corresponds to the display content having the position identification of (1, 50)˜(1, 60) and the content having the position identification of (1, 60)˜(1, 100) of the excess portion.
Further, in one exemplary embodiment, based on the excess portion of the display content indicated by the sliding distance, the application process may also draw an extra portion of display content (for example, 1.2 times the excess portion), so that when the system process detects another sliding operation, the interface delivery process controls the touch screen to display the extra drawn display content. Thus, a waiting time for the application process to transmit the drawn display content is reduced, and a response speed of the sliding operation is increased.
In the illustrated embodiment, the sliding distance of the sliding operation is assumed to be the same as a moving distance of the display window. In other embodiments, according to different system configures, the sliding distance of the sliding operation may be proportional to the moving distance of the display window. For example, the sliding distance of the sliding operation is 1 cm, and the moving distance of the display window is 2 cm.
In step 207, the interface delivery process controls the touch screen to display a display content corresponding to the moved display window.
In one exemplary embodiment, when the display content indicated by the sliding distance does not exceed the display content drawn by the application process, the display window that has been moved corresponds to the display content, and the interface delivery process controls the touch screen to display the display content corresponding to the display window that has been moved.
In one exemplary embodiment, when the display content indicated by the sliding distance exceeds the display content drawn by the application process, the display window that has been moved corresponds to the display content and the excess portion, and the interface delivery process controls the touch screen to display the display content corresponding to the display window that has been moved and the excess portion.
Compared to the related art, the above described methods for responding to the sliding operation reduce a time from the sliding operation being input to display content being output on the screen. For example, assuming that the size of the display content is 1.2 times larger than the size of the touch screen, for an apparatus of 60 frames/second, the time from the sliding operation being input to display content being output on the screen may be reduced by 16.6 milliseconds.
In the above described methods for responding to a sliding operation, with the application process drawing a display content in a size larger than a size of the touch screen, when the system process detects a sliding operation, the system process transmits related data of the sliding operation to the application process and the interface delivery process, triggers the interface delivery process to move a display window on the drawn display content, so as to control the touch screen to display a display content indicated by the sliding operation. Thus, the time that the interface delivery process waits for the application process to draw is reduced, and a response speed of the sliding operation is increased, such that synchronization of screen display and the sliding operation is enhanced.
The application module 502 is configured to draw a display content in a size larger than a size of the touch screen.
The system module 501 is connected with the application module 502 and the interface delivery module 503, and the application module 502 is connected with the interface delivery module 503. When the system module 501 detects the sliding operation, the system module 501 acquires a sliding distance and a sliding direction of the sliding operation. The system module 501 transmits the sliding distance and the sliding direction of the sliding operation to the application module 502 and the interface delivery module 503. When the interface delivery module 503 receives the sliding distance and the sliding direction, the interface delivery module 503 moves a display window in the sliding direction, according to the sliding distance, and controls the touch screen to display a display content corresponding to the display window that has been moved.
In one exemplary embodiment, when the application module 502 determines that the display content indicated by the sliding distance exceeds the display content drawn by the application module, the application module 502 draws an excess portion of the display content indicated by the sliding distance according to the sliding distance and the display content, and transmits the excess portion to the interface delivery module. Correspondingly, when the interface delivery module 503 receives the excess portion, the interface delivery module 503 controls the touch screen to display the display content corresponding to the display window that has been moved and the excess portion.
In one exemplary embodiment, when the application module 502 transmits the excess portion to the interface delivery module 503, the application module 502 transmits a position identification of the excess portion to the interface delivery module 503. Correspondingly, the interface delivery module 503 controls the touch screen to display the display content corresponding to the display window that has been moved and the excess portion, according to the position identification of the excess portion.
In one exemplary embodiment, when the interface delivery module 503 receives the sliding distance and the sliding direction, the interface delivery module 503 moves the display window by the sliding distance in the sliding direction.
By using the device 500, a response speed of the sliding operation is increased, such that synchronization of screen display and the sliding operation is enhanced.
The division of the modules in the above embodiment is for illustrative purposes only and, in actual applications, the above operations may be performed by different modules as needed. That is, the internal structure of the device 500 can be divided into different modules, to perform all or a part of the above-described operations.
