android - VideoView 变量有错误的值

Question

有谁知道为什么我的应用程序在打印出 VideoView 中的变量时只返回错误的值？

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    VideoView video = (VideoView)findViewById(R.id.introvideo);
    VideoThread IntroClip = new VideoThread();
    IntroClip.execute(video);
}

private class VideoThread extends AsyncTask<VideoView, Integer, VideoView> {
        @Override
        protected VideoView doInBackground(VideoView... video) {
        video[0].setVideoPath("android.resource://" + getPackageName() + "/" + R.raw.intro);
            return video[0];
        }

    protected void onPostExecute(VideoView video) {
        video.start();
    }
}

如果我尝试打印 video.getheight 它始终为 0，video.IsPlaying 始终为 false 等等。我必须找出视频何时停止播放。换句话说，在 onCreate 方法中是这样的:

while(video.IsPlaying())
{



}

 /*Stopped playing, continue...*/

但如前所述，该值始终为 false :-/

找到解决方案:

VideoThread IntroClip = new VideoThread();
IntroClip.execute(video);
    video.setOnCompletionListener(new MediaPlayer.OnCompletionListener(){
        public void onCompletion(MediaPlayer mp) {
            setContentView(R.layout.loginmenu);
        }
    });
