VideoView uri更改，再次加载

Question

当VideoView URI发生变化时，我希望mVideoView可以重新加载，我该怎么办？ VideoView方法是：

    mVideoView.setVideoURI(Uri.parse(videoViewUri));
    if (mVideoView.isPlaying()) {
        mVideoView.stopPlayback();
        if (isWifi()) {
            mVideoView.start();
        }
        Log.i("quickshare_isshow", "heheheheheh");
    } else {
        if (isWifi()) {
            mVideoView.start();
            Log.i("uri", videoViewUri);
        }
    }
