Comment afficher DialogFragment de Fragment dans actionBar android

Question

J'utilise des onglets ActionBar avec des fragments. A l'intérieur d'un fragment j'ai un bouton. Je veux montrer un DialogFragment (à l'intérieur de mon fragment) quand le bouton est pressé. Comment puis je faire ça?

C'est mon code

public class MainActivity extends FragmentActivity implements EditNameDialogListener { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     //showEditDialog(); 
     ActionBar actionbar = getActionBar(); 
     // Tell the ActionBar we want to use Tabs. 
     actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 
     // initiating both tabs and set text to it. 
     ActionBar.Tab InboxTab = actionbar.newTab().setText("One"); 
     ActionBar.Tab SentTab = actionbar.newTab().setText("Two"); 

     Fragment InboxFragment = new Inbox(); 
     Fragment SentFragment = new SentBox(); 
     InboxTab.setTabListener(new MyTabsListener(InboxFragment)); 
     SentTab.setTabListener(new MyTabsListener(SentFragment)); 
     actionbar.addTab(InboxTab); 
     actionbar.addTab(SentTab); 
    } 

    private void showEditDialog() { 
     FragmentManager fm = getSupportFragmentManager(); 
     EditNameDialog editNameDialog = new EditNameDialog(); 
     editNameDialog.show(fm, "fragment_edit_name"); 
    } 

    @Override 
    public void onFinishEditDialog(String inputText) { 
     Toast.makeText(this, "Hi, " + inputText, Toast.LENGTH_SHORT).show(); 
    } 

} 
class MyTabsListener implements ActionBar.TabListener { 
    public Fragment fragment; 

    public MyTabsListener(Fragment fragment) { 
     this.fragment = fragment; 
    } 
    public class Inbox extends Fragment implements EditNameDialogListener{ 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
      // Inflate the layout for this fragment 
      Utility util = new Utility(getActivity()); 
      View view = inflater.inflate(R.layout.inbox, container, false); 
      ArrayList<String[]> searchResults = util.ReadFile(); 

      final ListView lv1 = (ListView) view.findViewById(R.id.inboxList); 
      lv1.setAdapter(new MyCustomBaseAdapter(getActivity(), searchResults)); 

      lv1.setOnItemClickListener(new OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
       Object o = lv1.getItemAtPosition(position); 
       String[] fullObject = (String[])o; 
       Toast.makeText(getActivity(), "You have chosen: " + " " + fullObject[0], Toast.LENGTH_LONG).show(); 
      } 
      }); 

      return view; 
     } 

     @Override 
     public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { 
      // TODO Auto-generated method stub 
      super.onCreateOptionsMenu(menu, inflater); 
     } 

     @Override 
     public boolean onOptionsItemSelected(MenuItem item) { 
      // TODO Auto-generated method stub 


      switch (item.getItemId()) { 
      case R.id.menu_settings: 

       showEditDialog(); 
       break;

     } 


    } 

     @Override 
     public void onTabReselected(Tab tab, FragmentTransaction ft) { 
      /* 
      * Toast.makeText(StartActivity.appContext, "Reselected!", 
      * Toast.LENGTH_LONG).show(); 
      */ 
     } 

     @Override 
     public void onTabSelected(Tab tab, FragmentTransaction ft) { 
      ft.replace(R.id.fragment_container, fragment); 
     } 

     @Override 
     public void onTabUnselected(Tab tab, FragmentTransaction ft) { 
      ft.remove(fragment); 
     } 

    } 

public class EditNameDialog extends DialogFragment implements OnEditorActionListener{

       EditNameDialogListener activity = (EditNameDialogListener) getActivity(); 
       activity.onFinishEditDialog(mEditText.getText().toString()); 
       this.dismiss(); 
       return true;

Answer 1

Utilisez cette option pour montrer dialogfragment du fragment

FragmentManager fm = getActivity().getSupportFragmentManager(); 
DialogFragment dialog = new MyDialogFragment(); // creating new object 
dialog.show(fm, "dialog"); 

Answer 2

Utilisez getChildFragmentManager() au lieu de getSupportFragmentManager(); comme celui-ci

FragmentManager fm = getActivity().getChildFragmentManager(); 
DialogFragment dialog = MyDialogFragment(); 
dialog.show(fm, "dialog"); 

Answer 3

Vous pouvez également appeler directement à l'aide getFragmentManager() .Pas besoin de getChildFragmentManager() ou getSupportFragmentManager()

DialogFragment dialog = new YourDialogFragment(); 
dialog.show(getFragmentManager(), "yourDialog"); 

Answer 4

FragmentManager fm = getActivity().getChildFragmentManager(); 
DialogFragment dialog = MyDialogFragment(); 
dialog.show(fm, "dialog"); 

Vous voulez passer les arguments au fragment de dialogue Comme nous passons les valeurs d'une activité à l'autre

FragmentManager fm = getActivity().getChildFragmentManager(); 
DialogFragment dialog = MyDialogFragment(); 

    Bundle args = new Bundle(); 
    args.putString("Key", "Your String"); 

    dialog.setArguments(args); 
    dialog.show(fm, "dialog");
