Android MediaController仅在安卓系统中点击后出现

我正在编写一个Android应用程序，其中我正在使用VideoView播放视频，但mediaController只有在点击屏幕后才会出现。这个过程正确吗？如果不是的话，我们怎么能不点击屏幕就让它出现呢

提前感谢，

您可以使用show（）方法显示它，但不能从包含VideoView的活动的OnCreate方法显示，因为VideoView尚未连接到SurfaceHolder（或类似的东西）。您必须使用类似的程序：

public class ActivityPreHomeVideo extends Activity implements SurfaceHolder.Callback{

    private VideoView mVideoView;
    private MediaController mMediaController;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.videolayout);
        mVideoView = (VideoView) findViewById(R.id.videolayout_video);

        mMediaController = new MediaController(this);
        mMediaController.setMediaPlayer(mVideoView);
        mMediaController.setAnchorView(mVideoView);
        mVideoView.setMediaController(mMediaController);

        //Set a callback when the VideoView is displayed
        mVideoView.getHolder().addCallback(this);

        mVideoView.setVideoPath("http://.../your_video.mp4");
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        // Display the mediaController for 3 seconds
        mMediaController.show();
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
    }
}
