The window display method provided by the embodiment of the application comprises the following steps: receiving a request to launch a second interface on a first interface; judging whether the request carries information for indicating that a small window is adopted to display the second interface or not; and if so, starting the second interface according to the information, and displaying the second interface by adopting a small window.
Description
Technical Field
The application relates to the technical field of smart televisions, in particular to a window display method and a smart television.
Background
An android system is generally adopted as an operating system of the current smart television.
The android 7.0 version and later systems can support a multitask stack to realize the function of displaying different Activities in multiple windows (Activity is one of the four most important components in android components, and one Activity corresponds to one application program interface). That is, each window in the multiple windows corresponds to one task stack, and each task stack stores the Activity to be displayed in the corresponding window. The android 7.0 version and later systems can support an application stack, a picture-in-picture mode stack, a split-screen mode stack and the like, and the multi-window display can be realized by the following steps: for example, one window corresponds to an application stack and another window corresponds to a picture-in-picture mode stack or a split-screen mode stack.
However, the system before the 7.0 version of the android does not support a multitask stack, and only supports an application stack, so that the application stack only corresponds to one window (usually referred to as a full-screen window), and therefore the function of displaying different activities in multiple windows cannot be realized.
For example, when a system of the android 5.0 version is adopted, ActivityA is displayed on the current screen in a full screen mode, when ActivityB is started on the ActivityA, because ActivityA and ActivityB are stored in the same application stack, according to the starting rule of Activity under the current android system, ActivityB needs to be pushed to the foreground to be displayed at the top of the application stack, namely ActivityB is displayed in a full screen mode by default, and ActivityB covers ActivityA, so that only one window displaying ActivityB can be displayed, and the function of simultaneously displaying the window of ActivityA and the window of ActivityB cannot be realized.
Therefore, it is required to provide a method for displaying different activities in multiple windows in one task stack, so as to avoid the limitation of the version of the android system and improve the user experience.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
According to the embodiment of the application, the Android frame Activity startup attribute and the Window display are modified, so that the multi-Window display effect can be achieved, and the limitation of an Android version is not required.
In the related art, in an Android system supporting only an application stack, when ActivityB is started on ActivityA, a display area of ActivityB corresponds to a full screen by default, and thus only one full screen window displaying ActivityB is displayed. Therefore, in order to realize the multi-window display effect under one application stack, the display area of the ActivityB is limited in the area limited by the range of the specified boundary mBounds, and the display area of the activityA is unchanged, so that the activityA and the activityB respectively correspond to different display windows.
Further, in the related art, since ActivityB is overlaid on ActivityA, the lifecycle of ActivityA enters a Pause state; and when the theme of the ActivityB is opaque, the Android system changes the state of the ActivityA from visible to invisible, so that the ActivityA cannot be displayed. Therefore, the me of the activityB is set to be transparent in the application, so that the state of the activityA is still visible according to the current Android system rule, and both the activityA and the activityB are displayed.
Various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.
Referring to fig. 1, an embodiment of the present application provides a window display method, including:
s101, receiving a request for starting a second interface on a first interface;
s102, judging whether the request carries information for indicating that a small window is adopted to display the second interface or not;
for example, the television system detects that the request carries the parameter FLAG _ ADJUST _ WIN _ ENABLED _ LEFT _ TOP _4, and determines to display the second interface using the widget.
And S103, if yes, starting the second interface according to the information, and displaying the second interface by adopting a small window.
Taking the example of starting activityB in activityA, the specific implementation method is as follows:
step one, ActivityA sends an Activity starting request to a framework, wherein the framework is a television system for example;
step two, the framework receives the request, checks the validity of the request and analyzes the information carried when ActivityB is started; the carried information comprises a group of predefined constants with special meanings, 20-30 common constants are used at present, and the carried information is used for indicating that the mode for starting activityB is a small window;
step three, the framework modifies the life cycle of the activityA into a Pause state, and then determines whether the activityA is modified into a visible state or not according to whether the theme of the activityB is transparent or not;
and step four, changing the activityB state into a visible state by the framework, and drawing an activityB interface UI according to mBounds set for activityB contained in the information.
More specifically, referring to fig. 2, a flowchart of a method for executing inside a frame for window display provided in an embodiment of the present application takes initiating an ActivityB in ActivityA as an example, and specifically includes:
firstly, a frame receives an activityB starting request sent by activityA, and detects whether the starting request contains a parameter FLAG _ ADJUST or not; the parameter is used for indicating that activityB adopts a small window display mode;
if the parameter FLAG _ ADJUST is not contained, enabling the activityB to be normally started in a full screen mode;
if the parameter FLAG _ ADJUST is included, the parameter Full Screen FLAG in the Activity Task corresponding to the Activity b is modified to be FLAG, that is, the frame forces the me of the Activity b to be transparent, so that the Activity a still keeps a visible state according to the current android system rule.
Then, detecting whether a start request carries a screen adjustment parameter WIN _ ENABLED _ LEFT _ TOP _4 or not; the parameter is used for indicating the boundary size and position of a display window corresponding to activityB;
if the screen adjustment parameters are not carried, the activityB is normally started in a full screen mode;
if the screen adjustment parameter is carried, calculating mBounds of the display window corresponding to the activityB according to the window adjustment coefficient in the parameter, and determining the position of the mBounds of the display window corresponding to the activityB in the screen according to the window position information in the parameter;
then, making a special mark on the ActivityB window starting attribute for indicating that the ActivityB window is displayed as a small window;
ActivityB then starts and is displayed with a small window. For example, as shown in fig. 3, a multi-window effect diagram for displaying ActivityB by using a small window provided by the embodiment of the present application is provided, in which the small window displaying ActivityB is located at the upper right of the screen, and the size of the boundary is one fourth of the size of the screen; the full screen window displaying ActivityA remains displayed full screen.
It should be noted that, in the interface shown in fig. 3, when the ActivityB is displayed by using a small window, the display area corresponding to the ActivityA may also be modified from a full-screen window to a small window to meet the user requirement, which is not limited in this embodiment.
It should be noted that, for example, the size of the border of the window corresponding to ActivityB may be one third, one fourth or one fifth of the screen, and the position of the window corresponding to ActivityB may be left upper, right upper, left lower or right lower. Combining the size and the position of the boundary, the display area of the window corresponding to the activityB can be 12, for example, the window corresponding to the activityB is positioned at the upper left of the screen, and the size of the boundary is one third of the screen; the window corresponding to the activityB is positioned at the upper left of the screen, and the size of the boundary is one fourth of the size of the screen; the window corresponding to the activityB is positioned at the upper left of the screen, and the size of the boundary is one fifth of that of the screen; the window corresponding to the activityB is positioned at the upper right of the screen, and the size of the boundary is one third of that of the screen; the window corresponding to the activityB is positioned at the upper right of the screen, and the size of the boundary is one fourth of the size of the screen; the window corresponding to the activityB is positioned at the upper right of the screen, and the size of the boundary is one fifth of that of the screen; the window corresponding to the activityB is positioned at the lower left of the screen, and the size of the boundary is one third of that of the screen; the window corresponding to the activityB is positioned at the lower left of the screen, and the size of the boundary is one fourth of the size of the screen; the window corresponding to the activityB is positioned at the lower left of the screen, and the size of the boundary is one fifth of that of the screen; the window corresponding to the activityB is positioned at the right lower part of the screen, and the size of the boundary is one third of that of the screen; the window corresponding to the activityB is positioned at the lower right of the screen, and the size of the boundary is one fourth of the size of the screen; the window corresponding to activityB is located at the lower right of the screen, and the size of the border is one fifth of the size of the screen.
Specifically, for example, when ActivityB is requested to be started, the following parameters are carried in the start request: after the frame receives the set of parameters, the frame firstly resolves to a parameter FLAG _ ADJUST, which indicates that ActivityB is displayed by a small window. Then setting the parameter Full Screen Flag in the Activity Task corresponding to ActivityB as Flag, which indicates that the me of ActivityB is transparent. Then, according to the convention, the window adjustment coefficient is 4 obtained from the _4 parameter, and the window obtained from the _ LEFT _ TOP parameter is positioned at the upper LEFT of the screen. Then, mBounds [0,1920/4,0,1080/4] corresponding to activityB is calculated according to the window adjustment coefficient, namely mBounds [0,480,0,270], that is, the width of activityB is one fourth of the width of the screen, namely the width is 480, and the height is one fourth of the height of the screen, namely the height is 270. Thus, the framework displays ActivityB at [0,480,0,270] m bones at the upper left of the screen while the display state of ActivityA remains unchanged.
When a user wants to display ActivityB in full screen, by clicking a key on a remote controller, the special mark of the original ActivityB displayed by using a small window is removed, for example, the marked parameters are: music-window-area, true, then ActivityB is displayed in a full screen window. As shown in fig. 4, an effect diagram of displaying ActivityB using a full-screen window is provided for the embodiment of the present application.
According to the embodiment of the application, the Android system Activity full-screen attribute is modified, the Android window display mechanism is modified, the interactive mode which can be flexibly applied to the whole intelligent television system is provided, the multi-window effect is achieved, and the method is applicable to various third-party applications (such as QQ music, love art, Youku and other various playing applications) without distinguishing Android versions.
