If I select an unexpandable group

Answer 1

Use this code this will work

expandableList.setOnGroupExpandListener(new OnGroupExpandListener() {
    int previousItem = -1;

    @Override
    public void onGroupExpand(int groupPosition) {
        if(groupPosition != previousItem )
            expandableList.collapseGroup(previousItem );
        previousItem = groupPosition;
    }
});
