来自 FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE :每当设备进入横向时，播放器都会自动进入全屏模式.

FULLSCREEN_FLAG_CONTROL_ORIENTATION :可以自动控制方向.

FULLSCREEN_FLAG_CONTROL_SYSTEM_UI :启用系统UI的自动控制.

FULLSCREEN_FLAG_CUSTOM_LAYOUT :禁用默认的全屏布局处理程序，使您可以手动控制向全屏布局的过渡.

或者，如果您实际上需要手动控制系统UI，请继续使用自定义布局标志，并确保处理UI元素的可见性.

I am getting following error while playing video in fullscreen mode (only in fullscreen). I am hiding all other components in the layout when it goes fullscreen but it says that android:id/statusBarBackground is the view that is causing the problem. How do I control that?

*** video playback stopped due to unauthorized overlay on top of player. The ***PlayerView is obscured by android.view.View{16771a9d V.ED.... ........ 0,0-1920,75 #102002f android:id/statusBarBackground}. The view is inside the ***PlayerView, with the distance in px between each edge of the obscuring view and the ***PlayerView being: left: 0, top: 0, right: 0, bottom: 1005.. 

My layout looks like this:

I am using FullScreenListener and in onFullScreen function, I hide all other elements in the layout except the videofragment.

@Override
    public void onFullscreen(boolean isFullscreen) {
        this.isFullscreen = isFullscreen;

        layout();
    }

Also I am adding following flag to the video player

player.addFullscreenControlFlag(***Player.FULLSCREEN_FLAG_CUSTOM_LAYOUT);

Taken from the documentation

FULLSCREEN_FLAG_CUSTOM_LAYOUT disables the default fullscreen layout handler, enabling you to control the transition to fullscreen layout manually.

As you see, setting that flag leaves to you the task of handling the UI elements' visibility, in particular those belonging to the System UI (status bar, navigation bar).

For this reason, if you fail to hide the status bar, the *** player will detect that a view is being displayed over it and will therefore throw that warning.

You can try with one of the following additional flags

FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE: causes the player to automatically enter fullscreen whenever the device enters landscape orientation.

FULLSCREEN_FLAG_CONTROL_ORIENTATION: enables automatic control of the orientation.

FULLSCREEN_FLAG_CONTROL_SYSTEM_UI: enables automatic control of system UI.

FULLSCREEN_FLAG_CUSTOM_LAYOUT: disables the default fullscreen layout handler, enabling you to control the transition to fullscreen layout manually.

or, if you actually need to have manual control over the System UI, keep using the custom layout flag and be sure to handle the UI elements' visibility.
