It will be understood by those skilled in the art that the structure shown in fig. 1 is only an illustration and is not intended to limit the structure of the electronic terminal 100. For example, the electronic terminal 100 may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.
In this embodiment, the electronic terminal 100 may be a display device such as a television.

For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The screen projection control device 110 includes at least one software function module which can be stored in the memory 111 in the form of software or Firmware (Firmware) or solidified in an Operating System (OS) of the electronic terminal 100. The processor 113 is configured to execute an executable module stored in the memory, such as a software functional module or a computer program included in the screen projection control apparatus 110.
The Memory 111 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.

The processor 113 may be an integrated circuit chip having signal processing capabilities. The Processor 113 may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; but may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components. The various methods, steps and logic blocks disclosed in the embodiments of the present invention may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
The peripheral interface 114 couples various input/output devices to the processor 113 and memory 111. In some embodiments, the peripheral interface 114, the processor 113, and the memory controller 112 may be implemented in a single chip. In other examples, they may be implemented separately from the individual chips.
The input/output unit 115 is used to provide input data to a user. The input/output unit 115 may be, but is not limited to, a mouse, a keyboard, and the like.
The display unit 116 provides an interactive interface (e.g., a user operation interface) between the electronic terminal 100 and a user or is used to display image data to a user reference. In this embodiment, the display unit may be a liquid crystal display or a touch display. In the case of a touch display, the display can be a capacitive touch screen or a resistive touch screen, which supports single-point and multi-point touch operations. The support of single-point and multi-point touch operations means that the touch display can sense touch operations simultaneously generated from one or more positions on the touch display, and the sensed touch operations are sent to the processor for calculation and processing.
In this embodiment, a floating panel object is stored in the electronic terminal, where the floating panel object includes an attribute parameter, and the attribute parameter includes a flag bit for not acquiring a page focus by default. The floating panel object initialization generation is described in detail below.
Firstly, defining a setting object mMenu LayoutParams of a suspension panel by a WindowManager.LayoutParams class, and instantiating by a construction function in the WindowManager.LayoutParams class to obtain an mMenu LayoutParams object, namely the suspension panel object.
Next, the type attribute of the floating panel object mmenullayoutparams is set to be a windowmanager. Wherein the TYPE attribute is set to TYPE _ PHONE TYPE so that the hover panel is at the upper level of the application page (Activity) so that the hover panel can be displayed over multiple pages.
Again, the flag attribute of the floating panel object mmenullayoutparams is set. The flag attribute is used for describing the functional characteristics of the mmenlayoutparams, and the setting of different functional characteristic attributes can enable the mmenlayoutparams object to have different behavior characteristics. In this embodiment, two attributes are set for the floating panel object mMenuLayoutParams:
window manager, LAYOUT params, flag _ NOT _ FOCUSABLE and window manager, LAYOUT params, flag _ LAYOUT _ NO _ LIMITS. The property of the Windows manager, the LayoutParams, the FLAG _ NOT _ FOCUSABLE represents that the floating panel cannot acquire the page, so that the situation that the floating panel always keeps a state of being capable of acquiring the page focus and other page elements except the floating panel cannot acquire the page focus is avoided, operation failure of other pages is caused, and each program of the electronic terminal is abnormal in operation. Secondly, the setting of the property window manager, LAYOUT params, flag _ LAYOUT _ NO _ LIMITS, indicates that the display of the floating panel is not controlled by the screen size of the electronic terminal, that is, the display position of the floating panel can be at any position of the screen, including the outer edge of the screen. The setting of the windowmanager, LAYOUT params, flag _ LAYOUT _ NO _ LIMITS attribute can realize that the suspension panel can be used when animation special effect display is performed. For example, the floating panel can move from the bottom screen to the inside of the screen when the floating panel is unfolded, and if the attribute is not set, the animation cannot be realized.
In this embodiment, the floating panel needs to be wrapped, and a conventional scheme may use a standard control of a system to implement a container of the whole floating panel, and the reason why the scheme cannot be used in the scheme is that the control panel is wrapped by the container of the system, so that information such as a key event in the container cannot be intercepted and processed, and the control panel cannot intercept information of a return key of the processing system. Therefore, in order to enable the control panel to process the page focus information of the system, for example, the return key information, the new container SCSettingView is used for floating the panel in this embodiment, and the container SCSettingView is inherited from the system container relatedlayout. Therefore, the SCSettingView container in this embodiment has all the functional characteristics of the system container RelativeLayout. Then, the DispatcKeyEvent method, which is a key distribution function, is rewritten inside the SCSettingView container. Therefore, the dispatchKeyEvent method is realized by the dispatchKeyEvent method overwritten in the SCSettingView container. Therefore, the container SCSettingView of the floating panel in this embodiment can intercept the key event distribution of the system, so that the container SCSettingView can intercept the return key information of the system.
In order to expose the returned key information intercepted by the SCSettingView container in this embodiment to the outside, the SCSettingView container is further provided with an interface for exposing the key information to the outside view of the container, and the specific interface design is as follows:
public interface IOnBackPressed{
void onBackPressed()；
}
the name of the interface is IOnBackPressed, only one function onBackPressed is arranged in the interface, the function is very simple and has no input parameter or output parameter, and after the container intercepts the page focus of the system, the message can be distributed to the outside of the container through the interface function onBackPressed, so that the corresponding processing unit in the electronic terminal can process the page focus.
Please refer to fig. 2, which is a flowchart illustrating a screen projection control method applied to the electronic terminal shown in fig. 1 according to a preferred embodiment of the present invention. The specific process shown in fig. 2 will be described in detail below.
And S101, after receiving a screen projection request, executing a floating panel object to control an electronic terminal to display screen projection data corresponding to the screen projection request.
The electronic terminal is provided with a suspended panel object, the suspended panel object comprises attribute parameters, and the attribute parameters comprise a flag bit for not acquiring a page focus by default.
In this embodiment, the screen projection data is displayed on the floating panel correspondingly formed by the floating panel object. Specifically, since the type attribute of the floating panel object mmenullayoutparam is set to a windowmanager.
In this embodiment, when the screen projection is not displayed in the electronic terminal, the default flag bit that does not obtain the page focus may prevent the floating panel object from intercepting the page focus.
Step S102, performing data clearing on a default flag bit that does not obtain a page focus in the floating panel object, so that the floating panel object can obtain the page focus.
In this embodiment, the page focus includes a plurality of kinds of operation information about the control page. For example, when the electronic terminal is a television, the page focus may be a return operation, a volume up-down operation, or the like of a remote controller.
In this embodiment, since the attribute parameters of the floating panel object include the default flag bit that does NOT obtain the page focus, which is window manager, layout params, flag _ NOT _ FOCUSABLE, the floating panel object cannot obtain the system focus under the condition that the default flag bit that does NOT obtain the page focus is valid. In order to enable the floating panel object to acquire the page focus, the flag bit Windowmanager, LayoutParams, FLAG _ NOT _ FOCUSABLE which does NOT acquire the page focus by default needs to be cleared, so that the floating panel object can acquire the system focus.
In this embodiment, step S102 may include: negating the default zone bit which does not acquire the page focus to obtain auxiliary clearing data; and performing bitwise AND operation on the auxiliary clearing data and the attribute parameters. The flag bit of the default non-acquired page focus in the attribute parameter can be cleared through the operation of the step S102.
In this embodiment, the attribute parameter of the floating panel object may be stored in a flags parameter. In this embodiment, all parameters in the flags are saved in binary form, that is, each attribute is described by one or several binary digits. When the floating panel is displayed, the floating panel object needs to intercept the page focus executed in the electronic terminal, for example, returning key information. In order to clear the data of the flag bit of the default non-acquired page focus and keep the other attribute parameters in the flags parameter unchanged, the following method can be implemented:
mMenuLayoutParams.flags＝mMenuLayoutParams.flags&(～WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE)。
the above implementation algorithm is described in detail below, and the implementation principle thereof is analyzed:
firstly, acquiring a binary number of WindowManager, Layout params, FLAG _ NOT _ FOCUSABLE;
then, bitwise negation is performed on windowmanager, layout params, flag _ NOT _ FOCUSABLE: windowmanager, layout params, flag _ NOT _ FOCUSABLE, which changes from 1 to 0 to 1 after the above operation.
Then, the method and the original FLAG data operate according to bitwise and (&), and since 1 and any data are followed by 1 and 0 and any data are followed by 0, the data of WindowManager.LayoutParams.FLAG _ NOT _ FOCUSABLE bit in the FLAGs can be cleared, so that the purpose of clearing the FLAG bit FLAG _ NOT _ FOCUSABLE of the default non-acquired page focus can be realized.
In this embodiment, when the floating panel object control electronic terminal is executed to display the screen projection data corresponding to the screen projection request, the flag bit for which the page focus is not acquired by default is cleared, so that the floating panel displayed by screen projection can acquire the focus information. That is, the floating panel can respond to some page focuses of the electronic terminal, for example, return keystroke messages can also be obtained.
And step S103, when the floating panel object intercepts any page focus, executing the operation corresponding to the page focus on the screen projection being displayed.
In one example, the electronic terminal is a television, and when the floating panel object intercepts a return key operation of a remote controller corresponding to the television, the floating panel object executes a return operation to hide the floating panel.
In this embodiment, after the operation corresponding to the page focus is performed on the currently displayed screen, the method further includes: and when the page focus intercepted by the floating panel object is the operation information of exiting or returning the displayed screen projection, carrying out recovery operation on the default zone bit which does not acquire the page focus in the floating panel object so as to prevent the floating panel object from acquiring the page focus.
In detail, performing bitwise or operation on the flag bit of the default non-acquisition page focus and the attribute parameters to recover the flag bit of the default non-acquisition page focus in the attribute parameters.
When the floating panel is displayed, the default FLAG _ NOT _ FOCUSABLE which does NOT acquire the page focus is cleared, when the electronic terminal hides the floating panel, the default FLAG _ NOT _ FOCUSABLE which does NOT acquire the page focus needs to be recovered, otherwise, the floating panel intercepts the page focus of the electronic terminal all the time, so that other pages cannot acquire the page focus. Therefore, when the floating panel is hidden, further resetting the FLAG bit FLAG _ NOT _ FOCUSABLE which does NOT acquire the page focus by default can be realized as follows:
mMenuLayoutParams.flags＝
mMenuLayoutParams.flags|
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE。
the above implementation algorithm is described in detail below, and the implementation principle thereof is analyzed:
the FLAG indicates the position of FLAG _ NOT _ FOCUSABLE FLAG bit, and the FLAG _ NOT _ FOCUSABLE FLAG bit is reset to 1 in the FLAG after the FLAG _ NOT _ FOCUSABLE FLAG bit is pressed or operated. By restoring the default FLAG _ NOT _ FOCUSABLE which does NOT acquire the page focus, the floating panel cannot acquire the page focus, and the page focus cannot be intercepted.
According to the screen projection control method, the default zone bit which does not acquire the page focus is set in the attribute parameters of the floating panel object, so that the page focus is prevented from being intercepted by mistake when a floating layer is not displayed on an electronic terminal; when the screen is projected in the electronic terminal, the default zone bit which does not acquire the page focus is cleared, so that the suspended panel object can intercept the page focus, the operation corresponding to the page focus is effectively executed, a user can operate the suspended panel more conveniently, and the user experience is improved.
In other embodiments, as shown in FIG. 3, the screen projection control method includes steps not at S201 to S205
Step S201, after receiving a screen projection request, executing a floating panel object to control an electronic terminal to display screen projection data corresponding to the screen projection request.
The electronic terminal is provided with a suspended panel object, the suspended panel object comprises attribute parameters, and the attribute parameters comprise a flag bit for not acquiring a page focus by default.
Step S202, performing data clearing on a default flag bit that does not obtain a page focus in the floating panel object, so that the floating panel object can obtain the page focus.
Steps S201 and S202 in this embodiment are similar to steps S101 and S102 in the previous method embodiment, and reference may be made to the description of the above method embodiment for steps S201 and S202 in this embodiment, which is not repeated herein.
Step S203, after executing the screen projection data corresponding to the screen projection request of the floating panel object control display, starting a monitoring function to monitor the state of the displayed screen projection.
And step S204, when the floating panel object intercepts a return key, executing the hiding operation on the screen projection being displayed.
Step S205, when the monitoring function monitors that the displayed screen projection is invisible, the floating panel corresponding to the displayed screen projection is removed.
Because the hiding of the floating panel is an animation process, the method in the embodiment can monitor whether the floating panel is hidden or not by monitoring the animation state corresponding to the floating panel when the floating panel is invisible. An animation listening message may be set to the hidden animation of the floating panel in order to capture the invisible state of the control panel. Specifically, the animation monitoring of the animation panel can be realized by calling addListener (newanalyzer. animation listener ()) method, and the listener has an interface function onaimit, which is called back when the animation is finished, so that the operation to be executed after hiding can be realized in the onaimit function.
In one example, the floating panel can be released in memory by calling a removeView method provided by the android system to remove the floating panel.
Step S206, performing a recovery operation on the default flag bit that does not obtain the page focus in the floating panel object to prevent the floating panel object from obtaining the page focus.
In detail, performing bitwise or operation on the flag bit of the default non-acquisition page focus and the attribute parameters to recover the flag bit of the default non-acquisition page focus in the attribute parameters.
When the floating panel is displayed, the default FLAG _ NOT _ FOCUSABLE which does NOT acquire the page focus is cleared, when the electronic terminal hides the floating panel, the default FLAG _ NOT _ FOCUSABLE which does NOT acquire the page focus needs to be recovered, otherwise, the floating panel intercepts the page focus of the electronic terminal all the time, so that other pages cannot acquire the page focus. Therefore, when the floating panel is hidden, further resetting the FLAG bit FLAG _ NOT _ FOCUSABLE which does NOT acquire the page focus by default can be realized as follows:
mMenuLayoutParams.flags＝
mMenuLayoutParams.flags|
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE。
the above implementation algorithm is described in detail below, and the implementation principle thereof is analyzed:
the FLAG indicates the position of FLAG _ NOT _ FOCUSABLE FLAG bit, and the FLAG _ NOT _ FOCUSABLE FLAG bit is reset to 1 in the FLAG after the FLAG _ NOT _ FOCUSABLE FLAG bit is pressed or operated. By restoring the default FLAG _ NOT _ FOCUSABLE which does NOT acquire the page focus, the floating panel cannot acquire the page focus, and the page focus cannot be intercepted.
When the suspension panel is hidden, the internal memory of the electronic terminal can be released by removing the suspension panel, so that the use space is saved. In addition, when the floating panel displays, the flag bit of the default non-acquired page focus is cleared; when the floating panel is hidden, the default zone bit which does not acquire the page focus is recovered, so that the floating panel can acquire the page focus without influencing other pages to acquire the page focus.
