detailed description

The technical solutions of the present application will be clearly and completely described in the following with reference to the specific embodiments of the present application and the corresponding drawings. It is apparent that the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

FIG. 1 is a multi-window display process according to an embodiment of the present application, which specifically includes the following steps:

S101: The terminal saves the display unit of the application in the corresponding container of the application, wherein the at least two activated applications are different, and the containers corresponding to different applications are different.

In the embodiment of the present application, the terminal includes, but is not limited to, a mobile phone, a tablet computer, etc., the terminal may use an Android (Android) operating system, and the application may be an application developed based on the Android platform.

On the terminal, after the application is started, each display unit of the application for displaying the interface of the application is started separately during the running of the application. The terminal can instantiate the application for the launched application a container (that is, the corresponding container of the application), and then save each display unit that has been activated by the application in the corresponding container, and subsequently used to display the corresponding application interface, of course, if the application is started during the running process For other display units of its own, the terminal also stores the other display units in the container corresponding to the application. There may be multiple activated applications on the terminal, and the terminal may instantiate a corresponding container for each launched application, and then save each display unit that has been activated by each application in the corresponding container.

Wherein, the container may be a stack. In an actual application, the stack data structure may be predefined, and then, whenever the application is started, the stack data structure is instantiated once, the corresponding stack is obtained, and the obtained The stack is used as the stack corresponding to the application. In addition, the stack data structure may not be instantiated when the application is started, but the stack data structure is instantiated multiple times in advance to obtain multiple stacks, and then, whenever it is started, When applied, a stack can be allocated to the application directly from the obtained multiple stacks as the stack corresponding to the application.

It should be noted that the display unit at the top of the stack is in an active state, and the display unit in the active state is called by the application process or thread to display the application interface corresponding to the display unit to the user. The content on the corresponding application interface can be refreshed in real time, and can interact with the user through preset various input commands, and at this time, other display units in the stack are in a Paused state or a Stopped state. The display unit in the Paused state or the Stopped state is not currently displayed to the user. When the application jumps from the current application interface to another application interface, the display unit corresponding to the other application interface is popped from the stack and re-saved at the top of the stack, that is, activated and switched to the Active state, correspondingly The storage location of the original display unit at the top of the stack moves downward and switches to the Paused state or the Stopped state, and the other application interface becomes the application interface currently displayed to the user.

S102: The terminal displays the window of the application according to the set window attribute of the application and each display unit saved in the container corresponding to the application.

In the embodiment of the present application, each display unit of the application includes various display elements, such as text, pictures, videos, controls, and the like, on the application interface defined in advance. In general, the application process calls the display list. When the application interface is displayed, the resolution information of the current terminal screen is obtained, and then the application interface is directly displayed on the terminal screen in an adaptive manner according to the resolution information. If the application interface corresponding to each display unit is to be displayed in a window manner, since the size of the window to be displayed and the position related information need to be determined, the window attribute may be preset to save the related information, and the lifetime of the window is Track and update these related information (from the time the window is created until the time the window is closed).

The window attribute may include a window length value, a window width value, a window coordinate value, and the like. The coordinate referenced by the window coordinate value is a two-dimensional coordinate on the current terminal screen, and the window coordinate value is used to locate the window. The position on the current terminal screen may be the coordinates of the intersection of the two diagonal lines of the window, or the coordinates of other specific points in the window area (such as the vertices of the window), and the window length value for the rectangular window. When the window width value and the window coordinate value are determined, the size and position of the window are determined.

In the embodiment of the present application, the terminal may determine the size and location of the window on the screen of the terminal according to the set window attribute of the application, and then invoke the corresponding display unit saved in the corresponding container of the application through a corresponding process or thread to display The application's window.

In the embodiment of the present application, for the terminal based on the Android operating system, the display unit specifically includes an activity, and the container specifically includes an activity stack.

It should be noted that the activity stack is a first-in/Last-Out data structure, and the valid data stored is the activity of the application corresponding to the activity stack. The following describes an example of saving the activity provided by the embodiment of the present application. It is assumed that the application A and the application B have been started on the terminal, wherein the application A has started two activities (activityA1, activityA2), and the application B has started three activities. (activityB1 ~ activityB3), the terminal instantiates two activity stacks for saving the activity of application A and the activity of application B respectively.

Figure 2 shows the activity stack of application A and application B. The left side is the stack of application A, and the right side is the activity stack of application B. Among them, only activityA2 and activityB3 located at the top of the two stacks are in the active state, and other activities are in the Paused state or the Stopped state. Obviously, at this time, application A is displaying the application interface corresponding to activityA2, and application B is displaying The application interface corresponding to activityB3. Assume that after application A jumps from the current application interface to the application interface corresponding to activityA1, the terminal can pop the activityA2 and activityA1 in the activity stack of application A in turn, and then add activityA2 and activityA1 to the stack, so that activityA1 is located in the application. At the top of the stack of A, activityA1 switches to the active state, and activityA2 switches to the Paused state or the Stopped state. Further, the related process or thread of the application A can call activityA1 to display the corresponding application interface.

In the prior art, all the activities of all the applications on the terminal are saved in the same activity stack, and the description continues with the above example. FIG. 3 shows the save mode of the activity provided by the prior art, and can be seen. The activity of the application A and the activity of the application B are all stored in the same activity stack, and the activity B3 of the application B is located at the top of the stack, and since the window attribute is not defined in the prior art, the terminal currently only displays and is The application interface corresponding to activityB3 is displayed in full screen, so that the user can only see the real-time content of the application interface and interact with the application interface.

As can be seen from the method and the prior art provided in the foregoing application, in the embodiment of the present application, since the terminal saves the activity of each application in the respective activity stack, instead of all the applications on the terminal, The activities are stored in the same activity stack, so that the activity state of each application's activity does not affect each other, each application can have an active activity (activity at the top of the activity stack), and because each application passes The window attributes determine the size and position of the respective windows. Therefore, the terminal can simultaneously display the real-time application interfaces of multiple applications in multiple windows.

In the embodiment of the present application, for the above step S102, the set window attribute of the application may be preset, or may be set by the user when the window of the application is to be displayed. There are a variety of setting methods, such as setting the window property of the application using a specific data structure, or setting the window property of the application using a configuration file, and then, when the window of the application needs to be displayed, A specific data structure or configuration file that reads the set window properties of the application so that subsequent display processes can be performed. The embodiment of the present application only sets the window of the application using a specific data structure. The attribute is described. Specifically, the window panel data structure is set (a data structure named WindowPanel can be set), and in the window panel data structure, the application window attribute is set, wherein the window attribute includes at least a window length value, Window width value and window coordinate value. Thereafter, the window of the application can be displayed correspondingly according to the window attribute of the application set in the WindowPanel data structure when the window of the application is started and subsequently operated. In practical applications, the WindowPanel data structure can be instantiated separately for each application, and the window properties of each application are respectively set in the WindowPanel data structure instantiated for each application.

Further, by the above description, the application interface corresponding to the activity at the top of the activity stack is the interface that the application currently displays to the user in the form of a window. Therefore, in the above step S102, the terminal according to the window attribute of the application Each display unit saved in the container corresponding to the application displays a window of the application, and specifically includes: determining, by the terminal, a window length value, a window width value, and a window coordinate value included in the window attribute of the application, and determining that the application is corresponding to the application The activity of the top of the activity stack, and then, because the terminal can determine the size of the window according to the determined window length value and the window width value, the position of the window can be determined according to the determined window coordinate value, and the window can be determined according to the determined activity. The real-time content of the app should be displayed, so the terminal can display the window correctly in real time. The terminal can set appropriate window length values, window width values, and window coordinate values for different applications according to the size of the screen, and can simultaneously display multiple application windows on the terminal screen completely or partially overlapping, for example, 4 shows that two applications are displayed on the same terminal screen at the same time. The upper window is the application A window, and the lower is the application B window. Their window length value and window width value are the same, only the window coordinate values are different. .

In addition, if the window coordinate value is not a coordinate value of a single point, but a set of coordinate values of a plurality of specific points, for example, may be coordinate values of at least three vertices of the window, since the coordinate values of the three vertices can be uniquely determined. The size and position of the window. Therefore, in this case, the window property may not include the window length value and the window width value, and the terminal can correctly display the application by determining the window coordinate value and the determined activity. window. Of course, in addition to window length values, window width values, window coordinate values, window properties can also contain other properties to more specifically describe the window. Status, such as window border style, window background style, and so on.

In the embodiment of the present application, after the terminal displays the window of each application, the user may need to perform certain operations on the window of the application, such as maximizing operation, maximizing post-reduction operation, minimizing operation, Drag operation, zoom operation, return operation, close operation, etc., so that the view of the window changes, therefore, in order to improve the convenience of the user operation, a corresponding window view control can be set for each window. Specifically, various window view controls can be set in the activity of the application, and the user interface (UI) corresponding to the window view controls is drawn on the window by using the view view class to provide operations to the user, and the window view controls are provided. Can be used to receive and process window property update instructions and/or window hidden instructions for the application. The operation corresponding to the window attribute update instruction may include a maximization operation, a maximum post-reduction operation, a drag operation, a zoom operation, and the like, and the window hiding instruction may include a minimization operation or the like. As shown in FIG. 4, the user can achieve the corresponding operation purpose by clicking the return key, the minimize key, the maximize key, the close key, and the like in the application window.

Further, when the terminal receives the window attribute update instruction for an application through the window view control, because the window attribute update instruction corresponds to each operation of adjusting the window size and/or the position, the terminal may update the instruction according to the window attribute update instruction. The window property of the application, and redisplaying the window of the application according to the updated window property and each activity saved in the activity stack corresponding to the application.

For the drag operation, the terminal can update the window coordinate value (only the window position changes). For the maximize operation, maximize the restore operation, the drag operation, and the zoom operation, the terminal may have the window length value, the window width value, and Window coordinate values are updated (window size and position change). After the terminal updates the window attribute and determines the activity at the top of the activity stack corresponding to the application, the window of the application may be redisplayed according to the updated window length value, the window width value, the window coordinate value, and the determined activity. .

Further, when the terminal receives a window hiding instruction (corresponding to a minimize operation) for an application through the window view control, the attribute of each activity of the application may be updated, and the application is redisplayed according to the updated attributes of each activity. Window, specific, terminal can determine each of the application Activity and each activity's dialog, and determine the wallpaper Z order, then, according to the window hidden instructions, update the application's Z sequence of each activity and the activity's dialog Z sequence, making the application's activities and each dialog's Z The value of the sequence is smaller than the value of the wallpaper Z order, and further, the window of the application is redisplayed according to the updated Z sequence of each activity and the Z order of each dialog. The dialog of the activity may be a popup window included in the activity and invoked by the activity to prompt the user to perform subsequent operations. The activity may not include a dialog, and may also include one or more dialogs.

Here, the Z sequence will be described based on the Android operating system. Each activity, the dialog of each activity, and other specific display units such as the wallpaper of the terminal screen (specific display units, hereinafter collectively referred to as visual units) have Z-order attributes, and are executed by the operating system through a Z-sequence list. Save and set, the Z sequence can indicate the display order of the corresponding visual unit in the Z-axis direction of the terminal screen when displayed on the terminal screen, wherein the more the Z-order value is displayed in the visual unit displayed on the upper layer of the terminal screen Large, that is, the visual unit can occlude other visual units whose Z-order value is less than its own Z-order value.

As shown in FIG. 5, the window of the application A and the window of the application B are displayed on the screen of the terminal. It is assumed that the Z-order value of the activity corresponding to the window of the application B is greater than the Z-order value of the activity corresponding to the window of the application A, then when the application A is When the window of the application and the window of the application B overlap, the overlapping area thereof displays the corresponding area of the window of the B, and the corresponding area of the window of the A is occluded, and the user is not visible.

According to the above description, after updating the Z order of each activity of the application and the Z sequence of the dialog of each activity to be smaller than the value of the wallpaper Z order, the window of the application is blocked by the wallpaper of the terminal screen, which is equivalent to the user. The window of the app is hidden.

Of course, the minimization operation can also be implemented without updating the Z order, but also by updating the window attributes. In this case, the content display area of the window can be updated by updating the window length value, the window width value, and the window coordinate value. The length and width are both set to 0, and the window view control bar (the area in the window that displays the window view control) is docked to a specific area of the screen (such as the bottom of the screen, or indented to the edge of the screen, etc.).

It should be noted that, in an actual application, when a terminal runs multiple applications, the user may only need real-time content of several specific applications, and the terminal may separately instantiate one for each specific application. The activity stack saves the activity of the specific application in the corresponding activity stack, and for other launched applications, only a common activity stack is instantiated, and the activities of the other launched applications are saved in the shared The activity stack. Thereby, the number of instantiated activity stacks can be reduced, and the consumption of terminal resources can be reduced.

In the embodiment of the present application, after the terminal displays the window of the application on the current screen, based on the user's operation on the window of the application, the terminal may receive other window function update instructions and window hiding instructions. For the operation instruction of the window of the application, the terminal may perform corresponding operations on the window of the application according to the received operation instruction, specifically including the following:

When the window of the application is displayed at the forefront of the current screen, and the terminal receives a window switching instruction for other applications, the window of the other application is displayed at the forefront of the current screen. That is, the operation corresponding to the window switching instruction is a switching operation.

Further, the terminal records each group of display content displayed in the window of the application, wherein only one set of display content is displayed at the same time in the window of the application. When the terminal receives the window return instruction for the application, the last set of display content of the current display content is displayed in the window of the application according to the recorded display contents of each group. That is, the operation corresponding to the window return instruction is a return operation.

Further, when the terminal receives the window close instruction for the application, the window of the application is closed. That is, the operation corresponding to the window close instruction is a close operation.

FIG. 6 is another multi-window display process according to an embodiment of the present application, which specifically includes the following steps:

S601: Save, for each application that has been started, the display unit of each application in at least one container.

In the embodiment of the present application, the display unit may be an activity, and the container may be an activity stack.

For each application that has been started, the terminal may instantiate an activity stack for each application to save the activity of the application, or directly instantiate one or more activity stacks for each application to share the activity stack. Save the activity of each application in these activities, and then use it for display.

S602: Display a plurality of windows according to the set window attribute and each display unit saved in the container, wherein at least one of the windows displays more than two display units.

In the embodiment of the present application, the terminal may display a window for each activated application according to the set window attribute and each display unit saved in the activity stack, so that only the application is displayed in each application window. Own activity.

Further, the terminal may first instantiate one or more windows according to the set window attribute, and then display two or more activities in each window according to each display unit saved in the activity stack, thereby improving The efficiency of the use of the window. Among them, two or more activities displayed in the same window may belong to the same application, or may belong to different applications.

Fig. 7 shows a schematic diagram of multi-window display in such a scenario, and it can be seen that two windows are displayed on the terminal screen.

The window "Apply A&B" is a window shared by the application A and the application B. On the left side of the display area of the window (that is, the left side of the dotted line) is the real-time content of the application A displayed according to the activity of the application A, in the window. The right side of the display area (ie, the right side of the dotted line) is the real-time content of the application B displayed according to the activity of the application B.

The window "App C" is the window of the application C, and the left side of the display area of the window (that is, the left side of the dotted line) is the first real-time content of the application C displayed according to an activity of the application C, in the window The right side of the display area (ie, the right side of the dotted line) is the second real-time content of the displayed application C according to another activity of the application C.

In practical applications, when the terminal needs to display more than two activities in the same window at the same time, the size and position (size and position) of each activity in the window display area can be in the window property of the window. Here, it can be referred to as a sub-area), so that each activity can be correctly displayed in the corresponding sub-area. Currently, depending on the settings of each sub-area, each activity may be displayed in an overlapping or partially overlapping manner in the same window, or may not be displayed in an overlapping manner.

Through the above method, since the terminal can instantiate multiple activity stacks to save the activity of each launched application, the terminal can simultaneously display according to the display unit at the top of each activity stack. Multiple windows, and different sub-areas can be divided into the window display area according to the set window attributes, so that an activity can be displayed in each sub-area in the same window, so that the terminal screen can display multiple simultaneously Real-time content of the app.
