what are you trying to delete and what do you want to be updated — tyczj, Jan 22 '13 at 17:32
I think that you probably just want to install a different fragment, instead... — G. Blake Meike, Jan 22 '13 at 17:40

It's better to define a viewGroup like a simple linearLayout (call it screen) in onCreateView function, and fill it in a function like init(). Each time you want to re-create your view, just remove all linearLayout's children and call init().

You did good job but it's more expensive than my simple solution.

I solved my problem replecing my fragmet with itself

the code is :

{

    arguments.putString(ItemDetailFragmentBlackBoard.ARG_ITEM_ID, id);
    ItemDetailFragmentBlackBoard fragment= new ItemDetailFragmentBlackBoard();
    fragment.setArguments(arguments);
    getFragmentManager().beginTransaction().replace(R.id.item_detail_container,   fragment).commit();   
}

ItemDetailFragmentBlackBoard is my fragment. I am deleting an Item from listView and after I delete it i re-call my fragment with de code above so I get un refresh!

public class ItemDetailFragmentBlackBoard extends Fragment {
    public static View _rootView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    if (_rootView == null || _isRefreshDashboard) {
        _rootView = inflater.inflate(R.layout.ItemDetailFragmentBlackBoard, container, false);

        // your code can't be change without refreshFragment in here..

        _isDashboardRefresh = false;
    }
}

// Global variables

public abstract class CommonBase extends AppCompatActivity {
    public static boolean _isRefreshDashboard;
}

// Refresh your fragment

CommonBase._isRefreshDashboard = true;

How call onCreateView Method or refresh my fragment?
