Just adding the missinge code, which i felt should be there in selected answer

public class MyListener : Java.Lang.Object, ExpandableListView.IOnChildClickListener
{
    public override bool OnChildClick (ExpandableListView parent, View v, int groupPosition, int childPosition, long id)
    {
        return base.OnChildClick (parent, v, groupPosition, childPosition, id);
    }
}

In OnCreateView add this specified listener to the the list view using below code

listview.SetOnChildClickListener(new MyListener());

This adds the above created class as a listener and receive callbacks.

C# doesn't support anonymous subclasses like Java, you will need to create a proper class that implements IOnChildClickListener:

public class MyListener : Java.Lang.Object, ExpandableListView.IOnChildClickListener
{
    public override bool OnChildClick (ExpandableListView parent, View v, int groupPosition, int childPosition, long id)
    {
        return base.OnChildClick (parent, v, groupPosition, childPosition, id);
    }
}

Or, depending on what you are trying to do, you may be better off using one of the events, like:

  • ExpandableListView.GroupCollapse
  • ExpandableListView.GroupExpand
  • AdapterView.ItemClick
  • AdapterView.ItemSelected
