YoutubePlayerSupportFragment 给出 Null Pointer 异常

Question

我想在我的应用程序中使用YoutubePlayerSupportFragment来播放YouTube视频，但它给出了以下异常：

01-08 14:52:11.953: E/AndroidRuntime(4069): FATAL EXCEPTION: main
01-08 14:52:11.953: E/AndroidRuntime(4069): java.lang.NullPointerException
01-08 14:52:11.953: E/AndroidRuntime(4069):     at com.google.android.youtube.player.YouTubePlayerSupportFragment.onStart(Unknown Source)
01-08 14:52:11.953: E/AndroidRuntime(4069):     at android.support.v4.app.Fragment.performStart(Fragment.java:1524)
01-08 14:52:11.953: E/AndroidRuntime(4069):     at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:957)
01-08 14:52:11.953: E/AndroidRuntime(4069):     at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1104)

我使用以下逻辑来替换我的片段：

 Fragment fragment=new EditBloop();
 final FragmentTransaction ft1 = getFragmentManager().beginTransaction(); 
 ft1.replace(R.id.container, fragment, "edit"); 
 ft1.commit();

我的片段类如下：

public class EditBloop extends YouTubePlayerSupportFragment 
  {
     public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle               savedInstanceState) {
    View view = inflater.inflate(R.layout.edit_bloop, null);
 }

和我的 xml edit_bloop：

<fragment
    android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
    android:id="@+id/youtubeplayerview"
    android:layout_width="match_parent"
    android:layout_height="200dp"/> 

所以，请指导我如何解决这个问题？

Answer 1

尝试使用 getSupportFragmentManager() ，如下所示：

EditBloop fragment = EditBloop.newInstance("edit");
getSupportFragmentManager().beginTransaction().replace(R.id.container, fragment).commit();
