Im возникли некоторые проблемы по реализации ListView внутри фрагмента, Im используя [ActionBarSherlock Side Меню панели навигации] [1]Android ListView внутри фрагмента

[1]: http://www.androidbegin.com/tutorial/implementing-actionbarsherlock-side-menu-navigation-drawer-in-android/ из этого учебника.

стороны Навигационная ссылка не работает должным образом, когда я нажимаю на втором меню будет показывать FRAGMENT2 гладко, но когда я нажимаю назад первое меню, чтобы показать снова fragment1 сбои приложения ..

вот мой код ..

MainActivity.java

Caused by: java.lang.IllegalArgumentException: Binary XML file line #7: Duplicate id 0x7f04002d, tag null, or parent id 0x0 with another fragment for com.androidbegin.sidemenututorial.WomenList

Примечание:Вы не можете надуть макет в виде фрагмента, когда этот макет включает в себя. Вложенные фрагменты поддерживаются только при динамическом добавлении к фрагменту.

Nested Fragments

Попробуйте После исправить:

public void onDestroyView() { 
      super.onDestroyView(); 
      Fragment fragment = (getFragmentManager().findFragmentById(R.id.your_fragment)); 
      FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction(); 
      ft.remove(fragment); 
      ft.commit(); 
//   ft.commitAllowingStateLoss(); //If u want to handle orientation as well 
    }

Тогда вы можете создать вид следующим образом:

private static View view; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    if (view != null) { 
     ViewGroup parent = (ViewGroup) view.getParent(); 
     if (parent != null) 
      parent.removeView(view); 
    } 
    try { 
     view = inflater.inflate(R.layout.main, container, false); 
    } catch (InflateException e) { 
     e.printStackTrace(); 
    } 
    return view; 
}

Я также предлагаю вам добавить следующую строку в MainActivity like:

ft.addToBackStack(null); 
// ft.addToBackStack(Fragment.TAG); // to identify that fragment. 
    ft.commit();
