Criminal Intent Application CAN'T GET THE DELETE FUNCTION OPERATIONAL

1

The code below is in the CrimeFragment class, but when I run the emulator the menu doesn’t even appear on the fragment_crime.xml.

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.fragment_crime, menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.delete_crime_action:
            UUID crimeId = mCrime.getId();
            CrimeLab.get(getActivity()).deleteCrime(crimeId);

            Toast.makeText(getActivity(), "toast_delete_crime", Toast.LENGTH_SHORT).show();
            getActivity().finish();

            return true;

        default:
            return super.onOptionsItemSelected(item);
    }
}

The fragment_crime.xml in the menu folder is;

<?xml version="1.0" encoding="utf-8"?>

Any suggestions anyone, please?
