无法解析 transaction.add(R.id.watch_video_player， youTubePlayerF

Question

无法解析方法 add(int，com.google.android.youtube.player.YouTubePlayerSupportFragment(

我想在主要活动中添加一个 youtube 播放器，也可以与另一个片段一起使用。

 YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.add(R.id.fragment, youTubePlayerFragment).commit();
       youTubePlayerFragment.initialize("KEY", new YouTubePlayer.OnInitializedListener() {
            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean wasRestored) {
                Toast.makeText(MainActivity.this, "onInitializationSuccess", Toast.LENGTH_SHORT).show();
                //load and play the video with current id
                youTubePlayer.loadVideo("S88M5nTXJak");
                youTubePlayer.play();
            }

Answer 1
