android - VideoView - MediaController 未显示

Question

我无法让它工作...每当我触摸我的视频时，没有任何事情发生...虽然我认为 MediaController 应该是可见的...

我目前使用以下功能来播放我的视频:

private void playCachedVideo(final VideoView videoView, final Context c, File f)
{
    //videoView.setZOrderOnTop(true);        
    videoView.setOnPreparedListener(new OnPreparedListener()
    {
        @Override
        public void onPrepared(MediaPlayer mp) 
        {
            mp.setOnVideoSizeChangedListener(new OnVideoSizeChangedListener() 
            { 
                @Override
                public void onVideoSizeChanged(MediaPlayer mp, int width, int height) 
                {
                    MediaController mediaController = new MediaController(c);
                    mediaController.setMediaPlayer(videoView);
                    mediaController.setAnchorView(videoView);
                    videoView.setMediaController(mediaController);
                }
            });
        }
    });
    videoView.setVideoURI(Uri.fromFile(f));
    videoView.start();
}

视频播放正常，但我无法显示任何 MediaController...

PS:我在 DialogFragment

中展示播放器

试试这个:

mMediaController = new MediaController(getActivity());

将c替换为getActivity()。
