Detect ExpandableListView group click

I have a custom ExpandableListView elv and I am able to detect when a Child is clicked with the code below.

    elv.setOnChildClickListener(new OnChildClickListener() {
        public boolean onChildClick(ExpandableListView parent, View v, int groupPosition,
                int childPosition, long id) {

However, when I change it to try to detect when a group item is clicked, this does not work. Does anyone know why?

Eclipse gives me the error:

The method setOnGroupClickListener(ExpandableListView.OnGroupClickListener) in the type ExpandableListView is not applicable for the arguments (new OnGroupClickListener(){})

    elv.setOnGroupClickListener(new OnGroupClickListener() {
        public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition,
                long id) {

private ExpandableListView listView;


listView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {

        @Override
        public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {

                      //get header
            TextView lbListenerHeader = parent.findViewById(R.id.lbListHeader);
            String data1= lbListenerHeader.getText().toString();
            Toast.makeText(getContext(),data1 ,Toast.LENGTH_SHORT).show();

                    //get list item
            TextView tv= (TextView) v.findViewById(R.id.lbListItem);
            ExpandableListView elv= (ExpandableListView) parent.findViewById(R.id.lvExp);
            String data= tv.getText().toString();
            Toast.makeText(getContext(),data ,Toast.LENGTH_SHORT).show();

            return true;
        }

    });

These methods can also be used inside ExpandableListAdapter

public void onGroupExpanded(int groupPosition) {}
public void onGroupCollapsed(int groupPosition) {}

Make sure you have imported android.widget.ExpandableListView.OnGroupClickListener right or replace

new OnGroupClickListener() {

with new android.widget.ExpandableListView.OnGroupClickListener {
