其中，所述存储器111可以是，但不限于，随机存取存储器(Random Access Memory，RAM)，只读存储器(Read Only Memory，ROM)，可编程只读存储器(Programmable Read-Only Memory，PROM)，可擦除只读存储器(Erasable Programmable Read-Only Memory，EPROM)，电可擦除只读存储器(Electric Erasable Programmable Read-Only  Memory，EEPROM)等。其中，存储器111配置成存储程序，所述处理器113在接收到执行指令后，执行所述程序，本公开实施例任一实施例揭示的过程定义的电子终端100所执行的方法可以应用于处理器113中，或者由处理器113实现。
所述处理器113可能是一种集成电路芯片，具有信号的处理能力。上述的处理器113可以是通用处理器，包括中央处理器(Central Processing Unit，简称CPU)、网络处理器(Network Processor，简称NP)等；还可以是数字信号处理器(DSP)、专用集成电路(ASIC)、现场可编程门阵列(FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。可以实现或者执行本公开实施例中的公开的各方法、步骤及逻辑框图。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。
所述外设接口114将各种输入/输入装置耦合至处理器113以及存储器111。在一些实施例中，外设接口114，处理器113以及存储控制器112可以在单个芯片中实现。在其他一些实例中，他们可以分别由独立的芯片实现。
所述输入输出单元115配置成提供给用户输入数据。所述输入输出单元115可以是，但不限于，鼠标和键盘等。
所述显示单元116在所述电子终端100与用户之间提供一个交互界面(例如用户操作界面)或配置成显示图像数据给用户参考。在本实施例中，所述显示单元可以是液晶显示器或触控显示器。若为触控显示器，其可为支持单点和多点触控操作的电容式触控屏或电阻式触控屏等。支持单点和多点触控操作是指触控显示器能感应到来自该触控显示器上一个或多个位置处同时产生的触控操作，并将该感应到的触控操作交由处理器进行计算和处理。
本实施例中，所述电子终端中存储有悬浮面板对象，所述悬浮面板对象包括属性参数，所述属性参数包括默认不获取页面焦点的标志位。下面对悬浮面板对象初始化生成进行详细描述。
首先，通过WindowManager.LayoutParams类来定义一个悬浮面板的设置对象mMenuLayoutParams，通过WindowManager.LayoutParams类中的构造函数来实例化得到一个mMenuLayoutParams对象，即所述悬浮面板对象。
其次，将悬浮面板对象mMenuLayoutParams的type属性设置为WindowManager.LayoutParams.TYPE_PHONE类型，配置成显示投屏的悬浮面板在视图中的层级关系。其中，将type属性设设置为TYPE_PHONE类型，以使悬浮面板是在应用页面(Activity)的上层，使悬浮面板可以在多个页面之上进行显示。
再次，将悬浮面板对象mMenuLayoutParams的flag属性进行设置。其中，flag属性用于描述mMenuLayoutParams的功能特性，不同的功能特性属性的设置会使得 mMenuLayoutParams对象具备有不同的行为特征。本实施例中，为所述悬浮面板对象mMenuLayoutParams设置了两个属性：WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE和WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS。所述WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE属性表示悬浮面板不能获取页面，从而避免悬浮面板一直保持能够获取到页面焦点的状态，会导致悬浮面板以外的其他页面元素无法获取到页面焦点，从而导致其它页面的操作失效，使得电子终端的各个程序运行异常。其次，所述WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS属性的设置表示悬浮面板的显示不受电子终端的屏幕大小的控制，也就是说悬浮面板的显示位置可以在屏幕的任意位置，包括可以在屏幕的外边缘进行显示。该WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS属性的设置可以实现悬浮面板在进行动画特效显示的时候使用。例如，悬浮面板展开的时候是可以从底部屏幕外逐步移动到屏幕内部的，如果没有设置该属性那么该动画的无法实现。
本实施例中，还需要对所述悬浮面板进行包裹设计，传统的方案中会使用***的标准控件来实现整个悬浮面板的容器，这种方案在本方案中无法使用是因为使用的***的容器来包裹控制面板，这样容器内部的按键事件等信息是无法被拦截和处理的，因此会导致控制面板无法拦截处理***的返回按键信息。因此，为了能够让控制面板能够处理***的页面焦点信息，例如，返回按键信息，本实施例中的为悬浮面板使用了新容器SCSettingView，并让该SCSettingView容器继承自***容器RelativeLayout。因此，本实施例中的SCSettingView容器具备了***容器RelativeLayout的所有功能特性。然后，所述SCSettingView容器内部复写的dispatchKeyEvent方法，该dispatchKeyEvent方法是按键分发函数。因此，本实施例中的悬浮面板的容器SCSettingView可以拦截***的按键事件分发，这样就使得容器SCSettingView能够拦截***的返回按键信息。
为了能够将本实施例中的SCSettingView容器拦截的返回按键信息进行对外暴露，所述SCSettingView容器还设置有接口来对容器外界视图暴露按键信息，具体的接口设计如下所示：
public interface IOnBackPressed{
void onBackPressed()；
}
该接口的名称是IOnBackPressed，接口内部仅设置一个函数onBackPressed，该函数很简单没有输入参数也没有输出参数，当容器拦截到***的页面焦点后就可以通过接口函数onBackPressed来将该消息分发到容器的外界，就可以使得电子终端中对应的处理单元处理 该页面焦点。
请参阅图2，是本公开较佳实施例提供的应用于图1所示的电子终端的投屏控制方法的流程图。下面将对图2所示的具体流程进行详细阐述。
步骤S101，接收到投屏请求后，执行悬浮面板对象控制电子终端显示所述投屏请求对应的投屏数据。
所述电子终端中存储有悬浮面板对象，所述悬浮面板对象包括属性参数，所述属性参数包括默认不获取页面焦点的标志位。
本实施例中，所述投屏数据显示在所述悬浮面板对象对应形成的悬浮面板上。具体地，由于悬浮面板对象mMenuLayoutParams的type属性设置为WindowManager.LayoutParams.TYPE_PHONE类型，因此，所述悬浮面板是在应用页面(Activity)的上层，使悬浮面板可以在多个页面之上进行显示。
本实施例中，在电子终端中未显示投屏时，所述默认不获取页面焦点的标志位可以使悬浮面板对象不能拦截页面焦点。
步骤S102，将所述悬浮面板对象中的默认不获取页面焦点的标志位进行数据清除，以使所述悬浮面板对象能够获取页面焦点。
本实施例中，所述页面焦点包括多种关于控制页面的操作信息。例如，所述电子终端是电视机时，所述页面焦点可以是遥控器的返回操作、音量加减操作等。
本实施例中，由于所述悬浮面板对象的属性参数中包括默认不获取页面焦点的标志位WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE，因此在默认不获取页面焦点的标志位有效的情况悬浮面板对象就无法获取到***焦点。为了使悬浮面板对象能获取页面焦点需要清除默认不获取页面焦点的标志位WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE，以使悬浮面板对象就能够获取到***焦点。
本实施例中，步骤S102可以包括：将所述默认不获取页面焦点的标志位进行取反操作得到辅助清除数据；将所述辅助清除数据与所述属性参数执行按位与操作。通过上述步骤S102的操作可以清除所述属性参数中的默认不获取页面焦点的标志位。
本实施例中，所述悬浮面板对象的属性参数可以保存在flags参数中。本实施例中，flags中的所有参数使用二进制的形式来进行保存的，也就是说每一个属性是一位或几位二进制数来进行描述的。当悬浮面板在显示的时候，悬浮面板对象需要拦截电子终端中执行的页面焦点，例如，返回按键信息。为了清除默认不获取页面焦点的标志位的数据并且保持flags参数中其它属性参数不变，可以通过如下方式实现：
mMenuLayoutParams.flags＝mMenuLayoutParams.flags&
(～WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE)。
下面详细描述上述的实现算法，并分析其中的实现原理：
首先，获取WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE的二进制数；
然后，对WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE进行按位取反操作：～WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE，通过上述操作后WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE原来是1的变成了0，原来是0的变成了1。
然后与原始的flags数据按照按位与(&)操作，由于1与任意数据“与”后都是1，0与任何数据“与”后都是0，因此就可以将flags中的WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE位的数据清除，以实现清除默认不获取页面焦点的标志位FLAG_NOT_FOCUSABLE的目的。
本实施例中，在执行悬浮面板对象控制电子终端显示所述投屏请求对应的投屏数据时，都清除默认不获取页面焦点的标志位，因此，能够使得投屏显示的悬浮面板能够获取到焦点信息。也就是悬浮面板能够响应电子终端的一些页面焦点，例如，也就可以获取返回按键信息。
步骤S103，当所述悬浮面板对象拦截到任一页面焦点时，对正在显示的投屏执行所述页面焦点对应的操作。
在一个实例中，所述电子终端是电视机，所述悬浮面板对象拦截到该电视机对应的遥控器的返回按键操作时，执行返回操作以隐藏悬浮面板。
本实施例中，在所述对正在显示的投屏执行所述页面焦点对应的操作之后，该方法还包括：当所述悬浮面板对象拦截到的页面焦点是退出或返回显示的投屏的操作信息时，将所述悬浮面板对象中的默认不获取页面焦点的标志位进行恢复操作，以防止所述悬浮面板对象获取所述页面焦点。
详细地，将所述默认不获取页面焦点的标志位与所述属性参数执行按位或操作，以恢复所述属性参数中的默认不获取页面焦点的标志位。
在显示悬浮面板的时，已经将默认不获取页面焦点的标志位FLAG_NOT_FOCUSABLE进行了清除操作，当电子终端隐藏悬浮面板时，需要对默认不获取页面焦点的标志位FLAG_NOT_FOCUSABLE进行恢复，否则悬浮面板将一直拦截电子终端的页面焦点，从而导致其他页面无法获取到页面焦点。因此，在悬浮面板被隐藏时，进一步地对默认不获取页面焦点的标志位FLAG_NOT_FOCUSABLE进行重置，可以通过如下方式实现：
mMenuLayoutParams.flags＝
mMenuLayoutParams.flags|WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE。
下面详细描述上述的实现算法，并分析其中的实现原理：
其中，“|”表示按位或操作，mMenuLayoutParams.flags表示原始的flags标志位信息，与FLAG_NOT_FOCUSABLE按位或操作后就可以将FLAG_NOT_FOCUSABLE标志位所在的位置在flag中进行了恢复置1。通过将所述默认不获取页面焦点的标志位FLAG_NOT_FOCUSABLE进行恢复，这样悬浮面板又不能够获取到页面焦点，也就无法对页面焦点进行拦截处理了。
本公开实施例的投屏控制方法，通过在所述悬浮面板对象的属性参数中设置默认不获取页面焦点的标志位，避免在电子终端未显示浮层时误拦截页面焦点；在电子终端中显示投屏时，将默认不获取页面焦点的标志位清除，从而使悬浮面板对象能够拦截到页面焦点，从而有效执行页面焦点对应的操作，使用户能够更方便地操作悬浮面板，提高用户体验。
在其它实施例中，如图3所示，所述投屏控制方法包括步骤S201至S205
步骤S201，接收到投屏请求后，执行悬浮面板对象控制电子终端显示所述投屏请求对应的投屏数据。
所述电子终端中存储有悬浮面板对象，所述悬浮面板对象包括属性参数，所述属性参数包括默认不获取页面焦点的标志位。
步骤S202，将所述悬浮面板对象中的默认不获取页面焦点的标志位进行数据清除，以使所述悬浮面板对象能够获取页面焦点。
本实施例中的步骤S201及S202与前一方法实施例中的步骤S101及S102相似，关于本实施例中的步骤S201及S202可以参考上述方法实施例中的描述，在此不再赘述。
步骤S203，在执行悬浮面板对象控制显示投屏请求对应的投屏数据之后，启动监听函数对显示的投屏的进行状态监听。
步骤S204，当所述悬浮面板对象拦截到返回按键时，对正在显示的投屏执行所述隐藏操作。
步骤S205，当所述监听函数监听到所述显示的投屏不可见后，移除所述显示的投屏对应的悬浮面板。
由于悬浮面板的隐藏是一个动画过程，本实施例中的方法可以在悬浮面板不可见时，通过监听所述悬浮面板对应的动画状态以监听所述悬浮面板是否被隐藏。为了捕获控制面板的不可见状态可以对悬浮面板的隐藏动画设置一个动画监听消息。具体地，可以通过调用addListener(new Animator.AnimatorListener())方法来实现动画面板的动画监听，该***中有一个接口函数onAnimationEnd，该函数会在动画结束的时候会被回调，这样我们就可以在onAnimationEnd该函数中实现隐藏后需要执行的操作。
在一个实例中，可以通过调用android***提供的removeView方法将悬浮面板移除， 从而将悬浮面板在内存中进行释放。
步骤S206，将所述悬浮面板对象中的默认不获取页面焦点的标志位进行恢复操作，以防止所述悬浮面板对象获取页面焦点。
详细地，将所述默认不获取页面焦点的标志位与所述属性参数执行按位或操作，以恢复所述属性参数中的默认不获取页面焦点的标志位。
在显示悬浮面板的时，已经将默认不获取页面焦点的标志位FLAG_NOT_FOCUSABLE进行了清除操作，当电子终端隐藏悬浮面板时，需要对默认不获取页面焦点的标志位FLAG_NOT_FOCUSABLE进行恢复，否则悬浮面板将一直拦截电子终端的页面焦点，从而导致其他页面无法获取到页面焦点。因此，在悬浮面板被隐藏时，进一步地对默认不获取页面焦点的标志位FLAG_NOT_FOCUSABLE进行重置，可以通过如下方式实现：
mMenuLayoutParams.flags＝
mMenuLayoutParams.flags|WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE。
下面详细描述上述的实现算法，并分析其中的实现原理：
其中，“|”表示按位或操作，mMenuLayoutParams.flags表示原始的flags标志位信息，与FLAG_NOT_FOCUSABLE按位或操作后就可以将FLAG_NOT_FOCUSABLE标志位所在的位置在flag中进行了恢复置1。通过将所述默认不获取页面焦点的标志位FLAG_NOT_FOCUSABLE进行恢复，这样悬浮面板又不能够获取到页面焦点，也就无法对页面焦点进行拦截处理了。
通过在所述悬浮面板被隐藏时，移除所述悬浮面板可以释放所述电子终端的内存，节省使用空间。另外，在悬浮面板显示时，清除所述默认不获取页面焦点的标志位；在悬浮面板隐藏时，恢复默认不获取页面焦点的标志位，可以使悬浮面板能够获取页面焦点的情况下，也不影响其它页面获取页面焦点。
本申请实施例还提供了一种投屏控制方法，应用于电子终端，所述电子终端中存储有悬浮面板对象，所述投屏控制方法包括以下步骤。
步骤S301，在所述悬浮面板被调用时，配置所述悬浮面板的焦点属性，使所述悬浮面板具备获得***页面焦点的能力。
在本申请实施例中，悬浮面板可以上使用电子终端进行投屏操作时的控制面板，该控制面板在没有进行投屏操作时不会在电子终端上进行显示，在进行投屏操作后，该控制面板就可以在电子终端上进行显示。该控制面板可以是位于应用页面(Activity)的上层的，可以在多个页面之上进行显示。
由于电子终端中的控制面板在展示过程中，通常采用悬浮层的方式实现，而在安卓操作***中悬浮层是无法响应***的按键信息的，即用户通过遥控器或触摸屏输入 的按键信息是不能被该控制面板接收到的。
在本申请中，在悬浮面板被调用时，先对悬浮面板的焦点属性进行配置，以改变悬浮面板不能获得按键信息的情况。
所述悬浮面板被调用前为默认不获取页面焦点状态，电子终端的页面焦点位于哪一层，该层即可获取***的按键信息。例如，如果应用层获取到了***的页面焦点，那么针对电子终端的按键操作就会在应用层中进行。在进行焦点属性配置时，可以确定所述悬浮面板的焦点状态；再将所述悬浮面板的焦点状态由默认不获取页面焦点状态改变为默认获取页面焦点状态。
详细的，可以先将所述默认不获取焦点标志位中的数据用二进制表示。对二进制表示后的所述默认不获取焦点标志位中的数据按位取反。将按位取反后的默认不获取焦点标志位与所述焦点属性数据进行按位与操作，以使所述焦点属性中的所述默认不获取焦点标志位被清除，使所述悬浮面板的焦点状态由默认不获取页面焦点状态改变为获取页面焦点状态。
例如，可以先定义一个悬浮面板mMenuLayoutParams，mMenuLayoutParams悬浮面板的属性设置为WindowManager.LayoutParams.TYPE_PHONE类型，表示该控制面板在视图中的层级关系，本方案中设置为TYPE_PHONE类型这样就能够保证控制面板是在应用页面的上层的，使得控制面板可以在多个页面之上进行显示。
在进行焦点属性配置时，悬浮面板的焦点属性可以定义为：WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE。在悬浮面板被调用时，该控制面板的焦点属性为默认获取页面焦点状态，如果不对该控制面板的焦点属性进行配置的话，就会导致该控制面板会一直处于获取页面焦点的状态，使得电子终端终端中的其他页面由于无法获取到焦点而出现操作失效、程序异常的情况。
悬浮面板属性的参数是通过二进制的形式来进行保存的，焦点属性WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE是二进制中的一位或几位。在悬浮面板被调用时，需要清除掉该悬浮面板的焦点属性WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE这一标志位，实现如下所示：
mMenuLayoutParams.flags＝mMenuLayoutParams.flags&
(～WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE)；
mMenuLayoutParams.flags为悬浮面板的属性参数，我们将焦点属性的参数用二进制表示后，对焦点属性参数中的二进制数据按位取反，原来数据是1的变成了0，原来是0的变成了1.
按位取反后的焦点属性参数再与原始的属性参数按照按位与(&)操作，由于1 与任意数据“与”操作后都得到1，0与任何数据“与”操作后都得到0，这样就可以将属性参数中的WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE这一标志位的数据清除掉，也就达到了清除悬浮面板属性参数中焦点属性的默认不获取焦点标志位的目的。
步骤S302，监听所述***的按键操作信息，当接收到按键操作信息时，根据所述按键操作信息，控制所述悬浮面板执行按键操作。
悬浮面板的属性参数中的默认不获取焦点标志位的数据被清除掉后，该悬浮面板就具备了获取页面焦点的功能。***中此时如果产生了按键操作，就会对该悬浮面板进行操作。此时，可以监听***的按键操作信息，在按键操作信息为返回操作时，即可根据该返回操作将该悬浮面板进行隐藏，即不在电子终端的显示屏上继续显示该悬浮面板。
详细的，在将悬浮面板进行隐藏时，配置所述悬浮面板的焦点属性，使所述悬浮面板不具备获得***页面焦点的能力。同时将所述悬浮面板进行移除，并在所述电子终端的内容中释放该悬浮面板对应的进程。用户操作电子终端的按键按下了返回按键后，就是希望悬浮面板可以在返回按键的操控下不再显示，即将悬浮面板进行隐藏。悬浮面板被隐藏后如果仍然具备获得页面焦点的能力，就会出现虽然电子终端没有显示悬浮面板，但页面焦点仍然会被悬浮面板获取，以至于***中针对其他页面的按键信息不会被正确的页面获取到，而出现异常。
本申请实施例中，通过先确定所述悬浮面板的焦点状态；将所述悬浮面板的焦点状态由默认获取页面焦点状态改变为默认不获取页面焦点状态。
具体的，可以将所述默认不获取焦点标志位与所述焦点属性数据进行按位或操作，以使所述焦点属性中的所述默认不获取焦点标志位被恢复，使所述悬浮面板的焦点状态由默认获取页面焦点状态改变为默认不获取页面焦点状态。
对该标志位进行重置，具体的实现如下所示：
mMenuLayoutParams.flags＝mMenuLayoutParams.flags|
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE；
接下来我们描述一下上述的实现原理，“|”表示按位或操作，mMenuLayoutParams.flags表示悬浮面板原始的属性，与FLAG_NOT_FOCUSABLE按位或操作后就可以将FLAG_NOT_FOCUSABLE标志位所在的位置在属性参数中置1。从而使得默认不获取焦点标志位被回复，这样悬浮面板又不能够获取到***焦点信息了，也就无法对***按键进行拦截处理了。
如前所述，本申请实施例中的悬浮面板被调用被显示时，具有获得***的页面焦 点的能力。通过再将悬浮面板的属性当中的焦点属性的状态改变，使得悬浮面板的焦点属性改变为默认不获取页面焦点状态，焦点属性改变后的悬浮面板就不再具备获得页面焦点的能力，页面焦点就可以被其他页面获取，从而使得***的按键信息不会被悬浮面板获取到，用户针对电子终端的按键操作也不会操作悬浮面板。
综上所述，本申请实施例中，通过在悬浮面板被调用时，改变悬浮面板的焦点属性，使悬浮面板具备获得页面焦点的能力，并可以在***产生按键操作时，具备获得页面焦点能力的悬浮面板可以获得按键信息，***的按键操作也就可以对悬浮面板进行操作，使得悬浮面板可以针对***的按键做出响应，提高用户的使用体验。
