ListView becomes null in fragment

I am trying to define a listview with a corresponding Adapter to add string to the listview. Howevewr, my listview comes as being null. The code is as below:-

public class CategoryFragment extends Fragment {
....
....
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {


    ListView listView = (ListView) getActivity().findViewById(R.id.cat_vacancies);
    listAdapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_2);
    listView.setAdapter(listAdapter);

....

}
}

What have I done wrong at this point?

my fragment xml is as follows( I have only added the relevant portions which I think may help in diagnosing the problem)

<RelativeLayout>

    <ListView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/cat_vacancies">

    </ListView>

</RelativeLayout>

P.S. This is, as far as I know, a silly mistake, but I have not yet completely grasped android completely, so excuse my problems.

Try whit that way

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
 View view = inflater.inflate(R.layout.yourFragmentXml, container, false);

    ListView listView = (ListView) view.findViewById(R.id.cat_vacancies);
    listAdapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_2);
    listView.setAdapter(listAdapter);

....

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

View view=inflater.inflate(R.layout.[layout id], container, false);
    ListView listView = (ListView) view.findViewById(R.id.cat_vacancies);
retrun view;
}
