YouTubePlayerSupportFragment Listener doesen't work

Question

在我的Fragment类PlaybackEventListener和PlayerStateChangeListener不起作用。它不会显示吐司。

这是我的代码：

进口：

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentTransaction; 
import android.util.Log; import android.view.LayoutInflater; 
import android.view.View; import android.view.ViewGroup; 
import android.widget.Toast;  
import com.google.android.youtube.player.YouTubeInitializationResult; 
import com.google.android.youtube.player.YouTubePlayer; 
import com.google.android.youtube.player.YouTubePlayer.OnInitializedListener; 
import com.google.android.youtube.player.YouTubePlayer.Provider; 
import com.google.android.youtube.player.YouTubePlayerSupportFragment; 

脚本：

private static final String API_KEY = "-------"; 
private static String VIDEO_ID = "------"; 
@Override 
public View onCreateView(final LayoutInflater inflater, final ViewGroup container, Bundle savedInstanceState) { 

    final View rootView = inflater.inflate(R.layout.you_tube_api, container, false); 

    final YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance(); 
    final FragmentTransaction transaction = getChildFragmentManager().beginTransaction(); 
    transaction.add(R.id.youtube_layout, youTubePlayerFragment).commit(); 

    youTubePlayerFragment.initialize(API_KEY, new OnInitializedListener() { 
     @Override 
     public void onInitializationSuccess(Provider provider, final YouTubePlayer player, boolean wasRestored) { 
      /*Listener*/ 

      final YouTubePlayer.PlaybackEventListener mPlaybackEventListener = new YouTubePlayer.PlaybackEventListener() { 

       @Override 
       public void onBuffering(boolean arg0) { 
       } 

       @Override 
       public void onPaused() { 

       } 

       @Override 
       public void onPlaying() { 

       } 

       @Override 
       public void onSeekTo(int arg0) { 
       } 

       @Override 
       public void onStopped() { 

       } 

      }; 
      final YouTubePlayer.PlayerStateChangeListener mPlayerStateChangeListener = new YouTubePlayer.PlayerStateChangeListener() { 

       @Override 
       public void onAdStarted() { 
       } 

       @Override 
       public void onError(YouTubePlayer.ErrorReason arg0) { 
       } 

       @Override 
       public void onLoaded(String arg0) { 
       } 

       @Override 
       public void onLoading() { 

       } 

       @Override 
       public void onVideoEnded() { 
        Toast.makeText(getActivity(),"END",Toast.LENGTH_LONG).show(); 
       } 

       @Override 
       public void onVideoStarted() { 

       } 
      }; 
      player.setPlayerStateChangeListener(mPlayerStateChangeListener); 
      player.setPlaybackEventListener(mPlaybackEventListener); 
      if (!wasRestored) { 
       player.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT); 
       player.loadVideo(VIDEO_ID); 
       player.play(); 
      } 
     } 

     @Override 
     public void onInitializationFailure(Provider provider, YouTubeInitializationResult error) { 
      String errorMessage = error.toString(); 
      Toast.makeText(getActivity(), errorMessage, Toast.LENGTH_LONG).show(); 
      Log.d("errorMessage:", errorMessage); 
     } 

    }); 
    return rootView; 
} 

有人能帮助我吗？

你可以用以下方法试试：

youTubePlayerFragment.initialize(API_KEY, new OnInitializedListener() { 
     @Override 
     public void onInitializationSuccess(Provider provider, final YouTubePlayer player, boolean wasRestored) { 
      /*Listener*/ 

      player.PlaybackEventListener mPlaybackEventListener = new YouTubePlayer.PlaybackEventListener() { 

       @Override 
       public void onBuffering(boolean arg0) { 
       } 

       @Override 
       public void onPaused() { 

       } 

       @Override 
       public void onPlaying() { 

       } 

       @Override 
       public void onSeekTo(int arg0) { 
       } 

       @Override 
       public void onStopped() { 

       } 

      }; 
      player.PlayerStateChangeListener mPlayerStateChangeListener = new YouTubePlayer.PlayerStateChangeListener() { 

       @Override 
       public void onAdStarted() { 
       } 

       @Override 
       public void onError(YouTubePlayer.ErrorReason arg0) { 
       } 

       @Override 
       public void onLoaded(String arg0) { 
       } 

       @Override 
       public void onLoading() { 

       } 

       @Override 
       public void onVideoEnded() { 
        Toast.makeText(getActivity(),"END",Toast.LENGTH_LONG).show(); 
       } 

       @Override 
       public void onVideoStarted() { 

       } 
      }; 

      if (!wasRestored) { 
       player.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT); 
       player.loadVideo(VIDEO_ID); 
       player.play(); 
      } 
     } 

     @Override 
     public void onInitializationFailure(Provider provider, YouTubeInitializationResult error) { 
      String errorMessage = error.toString(); 
      Toast.makeText(getActivity(), errorMessage, Toast.LENGTH_LONG).show(); 
      Log.d("errorMessage:", errorMessage); 
     } 

    }); 

我希望这会帮助你。
