Проблема с фрагментом OptionsMenu при вызове фрагмента?

Question

MainActivity

public class MainActivity extends AppCompatActivity { 

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    if (savedInstanceState == null) { 
     getSupportFragmentManager().beginTransaction() 
       .add(R.id.fragment_container, new LayOutOne()).commit(); 
    } 

} 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.menu, menu); 
    return true; 
} 

public boolean onOptionsItemSelected(MenuItem item) { 
    int id = item.getItemId(); 
    switch (id) { 
     case R.id.settings: 
      getSupportFragmentManager().beginTransaction() 
        .replace(R.id.fragment_container, new PrefFragment()) 
        .addToBackStack(null) 
        .commit(); 
      break; 
    } 
    return super.onOptionsItemSelected(item); 
} 

PrefFragmentList расширяет PreferenceFragment

public class PrefFragmentList extends PreferenceFragment { 

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    addPreferencesFromResource(R.xml.settings); 

} 

PrefFragment расширяет фрагмент

public class PrefFragment extends Fragment { 
private View v; 
public View onCreateView(LayoutInflater inflater, ViewGroup container,  Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    v = inflater.inflate(R.layout.layout_settings, null); 
    setHasOptionsMenu(true); 
    return v; 
} 
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) 
{ 
    menu.findItem(R.id.settings).setVisible(true).setEnabled(false).setChecked(true).setChecked(true); 
    super.onCreateOptionsMenu(menu, inflater); 
} 

ПРОБЛЕМА:

MainActivity call PrefFragment из OptionMenu, когда я возвращаюсь в MainActivity и повторно вызываю PrefFragment, сбой приложения.

Answer 1

Я пытаюсь заменить в OnCreateView:

final View rootView = inflater.inflate(R.layout.fragment_profile, container, false); 

с:

if (rootView != null) { 
      ViewGroup parent = (ViewGroup) rootView.getParent(); 
      if (parent != null) 
       parent.removeView(rootView); 
     } 
     try { 
      rootView = inflater.inflate(R.layout.layout_settings, container, false); 
     } catch (InflateException e) { 
     } 
     return rootView; 

прекрасно работают и устранить эту ошибку:
