È mostrare questo errore ora, ho provato altri modi e ottenere NullPointerException. C'è un modo possibile per inserire YouTubePlayerSupportFragment in un frammento di swipe?

Answer 1

Prova

transaction.replace(R.id.youTubePlayer, youTubePlayerFragment).commit(); 

nel vostro onCreateView o semplicemente recuperare il frammento direttamente (lo avete nel vostro layout) utilizzando

YouTubePlayerSupportFragment youTubePlayerFragment = getFragmentManager().findFragmentById(R.id.youTubePlayer); 

Answer 2

Prima invece di

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

uso FrameLayout

<FrameLayout 
     android:id="@+id/frame_fragment" 
     android:layout_width="match_parent" 
     android:layout_height="200dp"></FrameLayout> 

poi dopo l'inizializzazione utilizzare

FragmentTransaction transaction = getFragmentManager().beginTransaction(); 
     transaction.replace(R.id.frame_fragment, youTubePlayerFragment); 
     transaction.commit();
