Is getActionBar() supposed to return null?

I'm trying to make a Toolbar in a fragment an Action Bar. This is what I do:

    View view = inflater.inflate(R.layout.fragment_sourceitem_list, viewGroup, false);

    android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) view.findViewById(R.id.toolbar);
    ((AppCompatActivity) mListener).setSupportActionBar(toolbar);

where mListener is the Activity that contains the fragment.

However, if I have the following straight after

    ActionBar actionbar = ((AppCompatActivity) mListener).getActionBar();

actionbar is null. How come it's still null even when the ActionBar has been set in the previous line already? Otherwise, what's a good way to set the property of the newly set ActionBar?

Thanks

Since you use AppCompatActivity you use the supportActionBar and therefor you need to use getSupportActionBar().

This supports older android versions than the normal Activity and ActionBar.
