Problem z metodą `onListItemClick` we Fragmencie.

Question

Witajcie,

w poniższym kodzie Fragmentu mam problem z metodą `onListItemClick`.

1. 'Method does not override method from its superclass'.

2. Metoda ta ma zadanie przekazać obiektowi nasłuchującemu informację o kliknięciu jednego z elementów ListView. Tyle, że mam informacje 'Method is never used'.

Jak naprawić te błędy?

/**
 * A simple {@link Fragment} subclass.
 */
public class WorkoutListFragment extends ListFragment {




    static interface WorkoutListListener {
        void itemClicked (long id);
    }

    private WorkoutListListener listener;


    public WorkoutListFragment() {
        // Required empty public constructor
    }


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

        String [] names = new String [Workout.workouts.length];
        for (int i=0; i<names.length; i++) {
            names [i] = Workout.workouts[i].getName();
        }
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(
                inflater.getContext(), android.R.layout.simple_list_item_1,names);
        setListAdapter(adapter);
        return super.onCreateView(inflater, container, savedInstanceState);
    }

    @Override
    public void onAttach (Context context) {
        super.onAttach(context);
        this.listener = (WorkoutListListener)context;
    }
    @Override
    public void onListItemClick (ListView 1, View v, int position, long id) {
        if (listener !=null) {
            listener.itemClicked(id);
        }
    }

}
