Android Youtube视频在片段中播放时被卡住

我是Android新手。我尝试在加载片段时播放youtube视频。这意味着视频应该在打开应用程序时播放。当我在活动中使用此功能时，它会工作（YouTubePlayerView），但当我使用YouTubePlayerSupportFragment视频时，它会被卡住，无法正常播放

这是youtube的代码：

YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
    FragmentTransaction transaction =getChildFragmentManager().beginTransaction();
    transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();
    youTubePlayerFragment.initialize("AIzaSyA9Kka548d7RZYVBypAy4UWgvDvbUCP16c", new YouTubePlayer.OnInitializedListener() {
        @Override
        public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
            if (!b) {
               YPlayer=youTubePlayer;

               // youTubePlayer.cueVideo("EjvfD61PXAw");
                YPlayer.loadVideo("EjvfD61PXAw");
                YPlayer.play();
            }


        }

        @Override
        public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

        }
    });

在xml中：

移除else块。您只需加载一次视频。@我已将其删除。但没有更改。视频正在启动，但已被卡住：（youTubePlayer是什么？您是如何启动的？请注意我在代码中所做的更改。我已初始化private youTubePlayer YPlayer；很抱歉，没有任何stacktrace或日志，我猜不出问题出在哪里。代码应该可以工作。您也可以发布活动代码。您是否正确地将片段附加到活动？
