I also faced the same problem. But I could solved my problem by the following code:

As I had 4 Headers in my expandable list, based on that i wrote like this

expListView.setOnGroupExpandListener(new OnGroupExpandListener() {

            @Override
            public void onGroupExpand(int groupPos) {
                // TODO Auto-generated method stub
                expListView.collapseGroup(groupPos+1);
                expListView.collapseGroup(groupPos-1);
                expListView.collapseGroup(groupPos-2);
                expListView.collapseGroup(groupPos+2);
                expListView.collapseGroup(groupPos+3);
                expListView.collapseGroup(groupPos-3);
            }
        });`
