Cannot cast from FragmentActivity to ListFragment
This error shows up when i do this:
This is in the MainActivity:
ListView lv = ((ListFragment) getActivity()).getListView();
but if I don't cast it to that the app crashes and I get

I will post the rest of the code If you guys need it. Ooh also I am calling the list fragment from the MainActivity with:
This is in the MainActivity
case 3:
return WorkersFragment.newInstance("Workers");
And the ListFragment instance:
This is in the ListFragment
public static WorkersFragment newInstance(String text) {
WorkersFragment pageFragment = new WorkersFragment();
return pageFragment;
}
Thanks for the help ahead of time!
