Update Fragment in the tab activity

Vote count:

0

To do this, i've created an actitivy that extends a FragmentActivity and implements an ActionBar.TabListener.

What i need to do is, when the user choose the option to edit an item, the form opens inside the tab, updating the fragment of tab and not starting a new activiy. I tried to use a FragmentTransaction in the List activity fragment, but, it didn't work. The code i tried was the following (at the ListFragment)

FragmentTransaction transaction = getFragmentManager()
                        .beginTransaction();
                transaction.replace(((ViewGroup) getView().getParent()).getId(),
                        newFragment);
                transaction.addToBackStack(null);
                transaction .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE); //
                // Commit the transaction
                transaction.commit();

Somebody can help me? Thanks What i need to do is, when the user choose the option to edit an item, the form opens inside the tab, updating the fragment of tab and not starting a new activiy.
