如何让HTML5视频URI在HTML5VFullScreen $ SurfaceVideoView在

我想，当用户点击了视频控制栏中的全屏按钮，得到一个HTML5视频URI。 根据此 ，在Android 4.0的HTML5视频的看法是一个SurfaceView，而不是一个VideoView。

有人能告诉我怎么去在SurfaceVideoView的URI？ 这是我的代码。 非常感谢。

webView.setWebChromeClient(new WebChromeClient(){
  @Override
  public void onShowCustomView(View view, CustomViewCallback callback) {
    super.onShowCustomView(view, callback);
    if (view instanceof FrameLayout){
      final FrameLayout frame = (FrameLayout) view;
      if (frame.getFocusedChild() instanceof SurfaceView){
        SurfaceView video= (SurfaceView) frame.getFocusedChild();
      }
    }
  });

Answer 1:

很简单，使用反射 。 把这个内部onShowCustomView()方法：

android.net.Uri mUri = null;

try
{
    @SuppressWarnings("rawtypes")
    Class _VideoSurfaceView_Class_ = Class.forName("android.webkit.HTML5VideoFullScreen$VideoSurfaceView");

    java.lang.reflect.Field _HTML5VideoFullScreen_Field_ = _VideoSurfaceView_Class_.getDeclaredField("this$0");

    _HTML5VideoFullScreen_Field_.setAccessible(true);

    Object _HTML5VideoFullScreen_Instance_ = _HTML5VideoFullScreen_Field_.get(((FrameLayout) view).getFocusedChild());

    @SuppressWarnings("rawtypes")
    Class _HTML5VideoView_Class_ = _HTML5VideoFullScreen_Field_.getType().getSuperclass();

    java.lang.reflect.Field _mUri_Field_ = _HTML5VideoView_Class_.getDeclaredField("mUri");

    _mUri_Field_.setAccessible(true);

    mUri =  (Uri) _mUri_Field_.get(_HTML5VideoFullScreen_Instance_);
}
catch (Exception ex)
{   
}

if (mUri != null)
{
    // There you have, mUri is the URI of the video
}
