YouTube API 视频不以片段开头

Question

我正在尝试在具有多个标签的活动中的片段中添加 YouTube 视频播放器。到目前为止，我已经设法运行代码，但我无法启动视频。我添加了一些日志来跟踪进度，似乎通过单击播放按钮，没有任何变化（日志中除外）并且视频无法播放，我不知道为什么。我得到的是这个冻结的屏幕：

我有 Fragment.java 的以下代码：

 import android.os.Bundle;
    import android.support.annotation.Nullable;
    import android.support.v4.app.Fragment;
    import android.support.v4.app.FragmentActivity;
    import android.util.Log;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.Button;

    import com.google.android.youtube.player.YouTubeInitializationResult;
    import com.google.android.youtube.player.YouTubePlayer;
    import com.google.android.youtube.player.YouTubePlayerFragment;
    import com.google.android.youtube.player.YouTubePlayerSupportFragment;
    import com.google.android.youtube.player.YouTubePlayerView;

    import java.util.ArrayList;
    import java.util.List;


    public class FragmentSedinte extends Fragment {
      View v;
      private static final String TAG = "Checking";
      Button btnPlay;
      YouTubePlayerView mYouTubePlayerView;
      YouTubePlayer.OnInitializedListener mOnInitializedListener;

      public FragmentSedinte() {}

      @Nullable
      @Override
      public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
        v = inflater.inflate(R.layout.fragment_sedinte, container, false);
        return v;
      }

      public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        //YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
        //youTubePlayerFragment.initialize("AIxxxxx",mOnInitializedListener);
        super.onViewCreated(view, savedInstanceState);
        this.v = view;
        Log.d(TAG, "onCreate: Starting.");
        //mYouTubePlayerView = (YouTubePlayerView)v.findViewById(R.id.youtubePlay);
        YouTubePlayerSupportFragment youTubePlayerFragment = (YouTubePlayerSupportFragment) getFragmentManager().findFragmentById(R.id.youtubePlay);
        mOnInitializedListener = new YouTubePlayer.OnInitializedListener() {
          @Override
          public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean wasRestored) {
            Log.d(TAG, "onClick: Done initialising");
            youTubePlayer.setFullscreen(true);
            youTubePlayer.loadVideo("tz-Wf9nEFao");
            youTubePlayer.play();

          }
          @Override
          public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
            Log.d(TAG, "onClick: Failed initializing");
          }
        };

        btnPlay = (Button) v.findViewById(R.id.btnPlay);
        btnPlay.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View view) {
            Log.d(TAG, "onClick: Initializing YouTube");
            //mYouTubePlayerView.initialize(YouTubeConfig.getApiKey(),mOnInitializedListener);
            mYouTubePlayerView.initialize("AIxxxxxxxx", mOnInitializedListener);
          }
        });
      }
    }

其中 Layout 有如下代码：

 <FrameLayout xmlns : android = "http://schemas.android.com/apk/res/android"
android: id = "@+id/container"
android: layout_width = "match_parent"
android: layout_height = "match_parent" >

  <LinearLayout
android: layout_width = "match_parent"
android: layout_height = "match_parent"
android: orientation = "vertical" >

  <fragment
android: id = "@+id/youtubePlay"
android: name = "com.google.android.youtube.player.YouTubePlayerSupportFragment"
android: layout_width = "match_parent"
android: layout_height = "wrap_content" / >

  <Button
android: id = "@+id/btnPlay"
android: layout_width = "100dp"
android: layout_height = "wrap_content"
android: layout_gravity = "center_horizontal"
android: gravity = "center_vertical|fill_vertical"
android: text = "Play"
android: textAlignment = "center" / >
  </LinearLayout>

  </FrameLayout>

当我点击播放时，我可以在 Logcat 中看到它被触发，但它没有开始播放视频。在日志中我有这个：

 02 - 27 10: 26: 50.092 17297 - 17320 / Package.recyclerview V / FA: Inactivity, disconnecting from the service
    02 - 27 10: 26: 54.137 17297 - 17297 / Package.recyclerview D / Checking: onClick: Initializing YouTube
    02 - 27 10: 26: 59.422 17297 - 17297 / Package.recyclerview D / Checking: onCreate: Starting.
    02 - 27 10: 27: 02.786 17297 - 17297 / Package.recyclerview D / Checking: onClick: Initializing YouTube

很明显该按钮已被触发，但似乎没有转到onInitializationSuccess。谁能帮我解决这个问题？

如有必要，我可以添加更多文件，但我认为问题出在此处发布的第一个文件。

你已经混合了YouTubePlayerFragment和YouTubePlayerView

从

更新您的代码

 mYouTubePlayerView = (YouTubePlayerView) v.findViewById(R.id.youtubePlay);

到

YouTubePlayerFragment youTubePlayerFragment = (YouTubePlayerFragment)getFragmentManager()
             .findFragmentById(R.id.youtubePlay);

更改加载

 @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
                                        boolean wasRestored) {
        if (!wasRestored) {
            player.loadVideo(YoutubeLinkRequest.getYouTubeID(youTubeURL), currentPlaying);
        }
        player.setPlayerStyle(YouTubePlayer.PlayerStyle.MINIMAL);
    }
