I am playing around with this example. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList2.html
I cannot figure
You need to subscribe to setOnChildClickListener
getExpandableListView().setOnChildClickListener(this);
and implement OnChildClickListener
@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition,
int childPosition, long id) {
// use groupPosition and childPosition to locate the current item in the adapter
return true;
}
