android - (Deprecated) Fragment onOptionsItemSelected not being called

EDIT: This question was for the deprecated sherlock action bar. Android support library should be used instead now

I have added an action bar menu option called share for my fragment which appears but the selection event is not being caught

I am adding it like this

@Override
public void onCreateOptionsMenu (Menu menu, MenuInflater inflater) {
    MenuItem item = menu.add(0, 7,0, R.string.share);
    item.setIcon(R.drawable.social_share).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
}

Trying to capture it in both the fragment and the fragment activity like

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
        case 7:
            Intent share = new Intent(Intent.ACTION_SEND);
            share.setType("text/plain");
            share.putExtra(Intent.EXTRA_TEXT, "I'm being sent!!");
            startActivity(Intent.createChooser(share, "Share Text"));
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

and I have setHasOptionsMenu(true); in the onCreate().

Same problems happened to me:

onMenuItemSelected events didn't get called in Fragment

Searched google cann't find a solution, and add onMenuItemSelected method in FragmentActivity doesn't solve it.

Finally resolve it by following reference to http://developer.android.com/guide/topics/ui/actionbar.html

Note: If you added the menu item from a fragment, via the Fragment class's onCreateOptionsMenu callback, then the system calls the respective onOptionsItemSelected() method for that fragment when the user selects one of the fragment's items. However the activity gets a chance to handle the event first, so the system calls onOptionsItemSelected() on the activity before calling the same callback for the fragment.

Which means only if you don't have that menu item handler in onOptionsItemSelected() on the activity, the onOptionsItemSelected() on the fragment will be called.

Code as following -----Remove the handler for R.action.add on FragmentActivity):

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
        case android.R.id.home:
            popBackStack();             
            return true;        
        case R.id.action_search:
            searchAction();
            return true;
        case R.id.action_logout:
            userLogout();
            return true;
        //case R.id.action_add:
            //return true;    
        default:
            return super.onOptionsItemSelected(item);
    }   
}

And the handler for R.action.add on Fragment looks like this:

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    Log.d("onOptionsItemSelected","yes");
    switch (item.getItemId()) {
        case R.id.action_add:
            add();
            return true;    
        default:
            return super.onOptionsItemSelected(item);
    }
}

Finally, remember to add

    setHasOptionsMenu(true);

in your onCreate method in Fragment
