稍加添加，它就可以在API级别21上运行+

videoViewContainer.setBackgroundColor(Color.BLACK);
((ViewGroup) webView.getParent()).addView(videoViewContainer);
webView.scrollTo(0,0); // centers full screen view
} else {

activityVideoView.addView(videoViewContainer,vg);

您还需要反映onHideCustomView
中的更改，在棒棒糖和更高版本（或者可能只是一个不同的WebView版本）中，调用cprack的
onHideCustomView（）
方法似乎不起作用。如果从exit fullscreen（退出全屏）按钮调用它，则它可以工作，但当您专门调用该方法时，它将仅退出全屏，但webView
保持空白。一种解决方法是简单地将这些代码行添加到onHideCustomView（）@SuppressWarnings("rawtypes")
Class c1 = Class.forName("android.webkit.HTML5VideoFullScreen$VideoSurfaceView");
Field f1 = c1.getDeclaredField("this$0");
f1.setAccessible(true);
@SuppressWarnings("rawtypes")
Class c2 = f1.getType().getSuperclass();
Field f2 = c2.getDeclaredField("mPlayer");
f2.setAccessible(true);
Object ___html5VideoViewInstance = f1.get(focusedChild); // Look at the code in my other answer to this same question to see whats focusedChild
Object ___mpInstance = f2.get(___html5VideoViewInstance); // This is the MediaPlayer instance.
OnCompletionListener ocl = new OnCompletionListener()
{
@Override
public void onCompletion(MediaPlayer mp)
{
// Do stuff
