Simply remember the last expanded group and collapse it before you
expand another group. This way you don't need a loop.
Try this:
private int currentHourPosition = -1; // initial value
@Override
public void onGroupExpand(int groupPosition) {
super.onGroupExpand(groupPosition);
if(currentHourPosition != -1 && currentHourPosition !=
groupPosition){
expandableListView.collapseGroup(currentHourPosition);
}
currentHourPosition = groupPosition;
// expandableListView.setSelectedGroup(groupPosition);
}
