How can I use onCreateOptionsMenu in a Fragment within a tab Activity? (Sherlock ActionBar)

问题

I have the following method overridden in my tab Activity and it works fine like that but I want specific option menu's for each fragment. When I put this in my fragment and press the menu button, nothing happens.

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    MenuInflater inflater = getSupportMenuInflater();
    inflater.inflate(R.menu.activity_calc, menu);
    return true;
}

You need to call setHasOptionsMenu(true) on your fragment before it can participate in the action bar.

May I suggest you check out http://code.google.com/p/sherlock-demo/. As BackpackOnHead describes, it uses ViewPager + ActionBar Tabs to let you navigate two different ways between the Fragments in an Activity. In this case, it is the FragmentTabs portion of the API Demos sample app, ported to ActionBarSherlock. The LoaderThrottle Fragment in particular has its own OptionsMenu items.
