迟到总比没有好.

问题等同于CSS中的z-index.全屏视频是在活动开始后添加的，并且在视图堆栈的最顶部，因此所有内容都在其中.

The problem is the equivalent to the z-index in css. The video in fullscreen is added after the activity is started and on the most top of the view stack so everything is under it.

在此示例中，我们将在所有内容上方放置一个全屏不可见对话框，以便我们可以将所需的任何手势附加到其视图(布局)并在活动中执行回调.

In this example, we are going to put a fullscreen-invisible dialog above everything so that we can attach any gesture we want to its view (layout) and execute callbacks in our activity.

1. 等待将视频添加到屏幕.您可以为当前播放器设置PlayerStateChangeListener，并在onVideoStarted回调方法中执行以下代码.

2. 以下代码将添加一个透明对话框，该对话框将位于视图层次结构的顶部(甚至高于视频):

1. Wait for the video to be added to the screen. You can set a PlayerStateChangeListener to your current player and execute the following code in onVideoStarted callback method.

2. The following code will add a transparent dialog which will be on top of the view hierarchy (even upper than the video):

// Add listeners to ***Player instance
player.setPlayerStateChangeListener(new PlayerStateChangeListener() {
   //... other methods 
     @Override
     public void onVideoStarted() {      

        // Setting style with no title (defined later in the answer)
        BasicPlayerActivity.this.mDialog = new Dialog(BasicPlayerActivity.this, R.style.AppTheme_NoActionBar_Fullscreen);     BasicPlayerActivity.this.mDialog.setContentView(R.layout.overlay_layout);
        View v = BasicPlayerActivity.this.mDialog.findViewById(R.id.container);

        //Adding touch listener (OR ANY LISTENER YOU WANT)  
        v.setOnTouchListener(new OnSwipeTouchListener(BasicPlayerActivity.this){        
            public void onSwipeRight() {
                // TODO: Previous Video or whatever
            }

            public void onSwipeLeft() {
                // TODO: Next video or whatever
            }
        });

        //Setting transparent dialog background (invisible)                                                                       
        BasicPlayerActivity.this.mDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
        BasicPlayerActivity.this.mDialog.show();
}
});

1. 在您的styles.xml中

1. In you styles.xml

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

    <style name="AppTheme.NoActionBar.Fullscreen">
        <item name="android:windowFullscreen">true</item>
        <item name="android:backgroundDimEnabled">false</item>
        <item name="android:backgroundDimAmount">0</item>
    </style>

您还可以设置cancel回调或执行任何操作.由你决定.

You can also set the cancel callback or whatever to do things. It is up to you.

我希望这将对您或有此问题的任何人有所帮助.

I hope this would help to you or anyone having this problem.
