ListView OnItemLongClickListener() not triggered

Question

I have a class that extends ListActivity where the list items respond to OnClick events. Adding an OnItemLongClickListener does not work. The onItemLongClick() function is not called (no log-output or Toast showing) but the normal OnClick() event is handled instead.

I want to display a contextual action bar upon long click. A minimum example using my code in a new project works fine. So my question is: What can possibly prevent the onItemLongClick() trigger from being triggered?

My minimum API is 11. I am also setting the listView to longClickable="true".

Activity code (selected functions):

public class EventListActivity extends ListActivity {

    private ArrayList<Event> arrEvents = null;
    private ArrayAdapter<Event> adpEvents = null;

    private ActionMode mActionMode = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // only create list adapter and set it
        arrEvents = new ArrayList<Event>();
        adpEvents = new ArrayAdapter<Event>(this, android.R.layout.simple_list_item_activated_2, android.R.id.text1, arrEvents) {
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                View view = super.getView(position, convertView, parent);
                TextView text1 = (TextView) view.findViewById(android.R.id.text1);
                TextView text2 = (TextView) view.findViewById(android.R.id.text2);
                text1.setText(arrEvents.get(position).getTitle());
                text2.setText(arrEvents.get(position).getDateTimeFormatted());
                return view;
            }
        };

        setListAdapter(adpEvents);

        // add CAB to ListView
        setupCAB();
    }


    @Override
    protected void onResume() {
        super.onResume();

        // populate list and refresh adapter
        createEventList();
        adpEvents.notifyDataSetChanged();

        // if list empty show emtpy msg, otherwise hide it
        setContentView(R.layout.activity_event_list);
        TextView empty = (TextView) findViewById(R.id.text_empty);
        if(arrEvents.isEmpty()) {
            empty.setVisibility(View.VISIBLE);
        } else {
            empty.setVisibility(View.GONE);
        }
    }


    private void setupCAB() {
        // Important: to select single mode
        getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);

        getListView().setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            // Called when the user long-clicks an item on the list
            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View row, int position, long rowid) {
                Log.w("EventListActivity", "Long click detected!");
                Toast.makeText(EventListActivity.this, "Long click detected!", Toast.LENGTH_SHORT).show();
                if (mActionMode != null) {
                    return false;
                }

                // Important: to mark the editing row as activated
                getListView().setItemChecked(position, true);

                // Start the CAB using the ActionMode.Callback defined above
                mActionMode = EventListActivity.this.startActionMode(mActionModeCallback);
                return true;
            }
        });
    }

    private ActionMode.Callback mActionModeCallback = new ActionMode.Callback() {
        // Called when the action mode is created; startActionMode() was called
        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            // Inflate a menu resource providing context menu items
            MenuInflater inflater = mode.getMenuInflater();
            inflater.inflate(R.menu.event_context, menu);
            return true;
        }

        // Called when the user enters the action mode
        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            // Disable the list to avoid selecting other elements while editing one
            EventListActivity.this.getListView().setEnabled(false);
            return true; // Return false if nothing is done
        }

        // Called when the user selects a contextual menu item
        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            switch (item.getItemId()) {
            case R.id.mnu_share_event:
                //TODO share event
                mode.finish();
                return true;
            default:
                return false;
            }
        }

        // Called when the user exits the action mode
        @Override
        public void onDestroyActionMode(ActionMode mode) {
            // Re-enable the list after edition
            EventListActivity.this.getListView().setEnabled(true);
            mActionMode = null;
        }
    };

}

When using a ListActivity or ListFragment there is no method you can override for the long-click, and getting access to the ListView is not possible in onCreateView(), since it is being controlled by the parent class.

So, to overcome this, I did this, since the getListView() command won't work until after the view is created:

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    mRecipeListView = this.getListView();
    mRecipeListView.setOnItemLongClickListener(new ListView.OnItemLongClickListener() {

        @Override
        public boolean onItemLongClick(AdapterView<?> arg0, View view, int position, long row_id) {
            // Process the long-click
        }
    });
}
