android - youtubeplayer在启动新视频时立即停止

Question

我能够初始化youtube视频，但是每当我尝试加载另一个播放现有视频的视频时，我都会创建一个方法，如何停止一个youtube视频，而后者通常用来停止和加载另一个视频。

        YouTubePlayer youTubePlayerMain;

        private void init(final String VIdeoId) {
        rvMainl.setVisibility(View.GONE);
        youTubeView.setVisibility(View.VISIBLE);
        if (youTubePlayerMain != null)
        {
            try{
                youTubePlayerMain.pause();
                youTubePlayerMain.cueVideo(VIdeoId);
            }
            catch(Exception e){
                e.printStackTrace();
            }
        }
      else 
        {

          youTubeView.initialize(Config.YOUTUBE_API_KEY, new YouTubePlayer.OnInitializedListener() {
                @Override
                public void onInitializationSuccess(YouTubePlayer.Provider provider, final YouTubePlayer youTubePlayer, boolean b) {
                    youTubePlayerMain = youTubePlayer;
                    if (!b) {
                        youTubePlayer.cueVideo(VIdeoId); // Plays https://www.youtube.com/watch?v=fhWaJi1Hsfo

                    }

                }

                @Override
                public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
                    if (youTubeInitializationResult.isUserRecoverableError()) {
                        youTubeInitializationResult.getErrorDialog(Youtube.this, RECOVERY_REQUEST).show();
                    } else {

                        Toast.makeText(Youtube.this, youTubeInitializationResult.toString(), Toast.LENGTH_LONG).show();
                    }
                }
            });
        }

    }

我发现问题，全局YouTubePlayer并第二次加载视频。
