Android VideoView uri更改，再次加载

当

VideoView URI

被更改时，我希望

mVideoView

可以重新加载，我该怎么办<代码>视频视图方法是：

    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);
        }
    }
