Implémentation de fragments imbriqués avec Android avec TabViewer

J'ai cette activité qui utilise des onglets, mais je ne suis pas sûr d'inclure des fragments imbriqués dans un seul onglet.Implémentation de fragments imbriqués avec Android avec TabViewer

Je voulais y parvenir:

Tab 1 
--Fragment A --> Fragment B

Pour imbriquer un fragment, appelez simplement getChildFragmentManager() sur le Fragment dans lequel vous souhaitez ajouter un fragment . Cela renvoie un FragmentManager que vous pouvez utiliser comme vous le faites normalement à partir de l'activité de haut niveau pour créer des transactions fragmentées. Par exemple, voici quelques code qui ajoute un fragment à partir d'un fragment classe existante:

Fragment videoFragment = new VideoPlayerFragment(); 
FragmentTransaction transaction = getChildFragmentManager().beginTransaction(); 
transaction.add(R.id.video_fragment, videoFragment).commit();

     for (int i = 0; i < 30; i++) { 
      builder.append(content).append(" "); 
     } 
     builder.deleteCharAt(builder.length() - 1); 
     fragment.mContent = builder.toString(); 

     return fragment; 
    } 

    private String mContent = "???"; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     if ((savedInstanceState != null) && savedInstanceState.containsKey(KEY_CONTENT)) { 
      mContent = savedInstanceState.getString(KEY_CONTENT); 
     } 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     TextView text = new TextView(getActivity()); 
     text.setGravity(Gravity.CENTER); 
     text.setText(mContent); 
     text.setTextSize(20 * getResources().getDisplayMetrics().density); 
     text.setPadding(20, 20, 20, 20); 


     inflater = getLayoutInflater(savedInstanceState); 

     LinearLayout layout = (LinearLayout) inflater.inflate(R.layout.activity_inside_activity, null); 

     //LinearLayout layout = new LinearLayout(getActivity()); 
     layout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); 
     layout.setGravity(Gravity.CENTER); 
     layout.addView(text); 

     return layout; 
    } 

    @Override 
    public void onSaveInstanceState(Bundle outState) { 
     super.onSaveInstanceState(outState); 
     outState.putString(KEY_CONTENT, mContent); 
    }

je me suis dit moi-même, je dois vous assurer que je suis dans la bonne page pour mettre les fragments imbriqués. En utilisant le switch, j'ai été capable d'imbriquer un fragment. Dans LaunchpadSectionFragment() étend un fragment, à l'intérieur de ce fragment appelle le getChildFragmentManager() pour commencer l'imbrication d'un autre fragment à l'intérieur LaunchpadSectionFragment.

@Override 
     public Fragment getItem(int i) { 
      switch (i) { 
      case 0: 

       return new LaunchpadSectionFragment(); 
}

Nesting:

Fragment videoFragment = new VideoPlayerFragment(); 
Fragment videoFragment2 = new VideoPlayerFragment2(); 
FragmentTransaction transaction = getChildFragmentManager().beginTransaction(); 
transaction.add(R.id.video_fragment, videoFragment); 
transaction.add(R.id.video_fragment2, videoFragment2); 
transaction.commit()
