Youtube播放器內選項卡式活動導致此錯誤

Question

我有選項卡式活動，我想在第三個選項卡上有YouTube視頻。

，這裏是我的java：

public class FragmentTutorial extends YouTubePlayerFragment { 

    YouTubePlayerView youTubePlayerView; 
    YouTubePlayer.OnInitializedListener onInitializedListener; 

    public FragmentTutorial() { 
     // Required empty public constructor 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 

     youTubePlayerView = (YouTubePlayerView) youTubePlayerView.findViewById(R.id.tutorial_youtube_player); 

     onInitializedListener = new YouTubePlayer.OnInitializedListener() { 
      @Override 
      public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) { 
       youTubePlayer.loadVideo("3LiubyYpEUk"); 
      } 

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

      } 
     }; 

     youTubePlayerView.initialize(PlayerConfig.API_KEY, onInitializedListener); 

     // Inflate the layout for this fragment 
     return inflater.inflate(R.layout.fragment_tutorial, container, false); 
    } 

} 

，這裏是我的XML：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.example.FragmentTutorial"> 

    <com.google.android.youtube.player.YouTubePlayerView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:id="@+id/tutorial_youtube_player" /> 

</FrameLayout> 

，這裏是我的MainActivity：

class FragmentAdapter extends FragmentPagerAdapter { 

     public FragmentAdapter(FragmentManager fm) { 
      super(fm); 
     } 

     @Override 
     public Fragment getItem(int position) { 
      switch (position){ 
       case 0: 
        return new FragmentHome(); 
       case 1: 
        return new FragmentCatalog(); 
       case 2: 
        return new FragmentTutorial(); 
      } 
      return null; 
     } 

     @Override 
     public int getCount() { 
      return 3; 
     } 


     @Override 
     public CharSequence getPageTitle(int position) { 
      switch (position){ 
       // 
       //Your tab titles 
       // 
       case 0: return "Home"; 
       case 1: return "Catalog"; 
       case 2: return "Tutorial"; 
       default: return null; 
      } 
     } 
    } 

，當我試圖運行此代碼，我得到這個以下錯誤：

Error:(80, 28) error: incompatible types: FragmentTutorial cannot be converted to Fragment 

我在這裏錯過了什麼？謝謝...

也許這是錯誤的片段類引起的，YouTubePlayerFragment延伸android.app.Fragment，FragmentPagerAdapter需要android.support.v4.app.Fragment，這不能被轉換

編輯：

嘗試使用android.support.v13.app.FragmentPagerAdapter代替android.support.v4.app.FragmentPagerAdapter（其他片段應該延伸android.app.Fragment）
