android - Expandable ListView

I am using expandableListView for UI design, so I am wondering for Android expandable listview, is there a way to allow only one list item expanded, i.e. when you click and expand an item, all other items are collapsed automatically.

Thanks

When you click one item you could loop through the rest and collapse each one except for the one you just clicked...

list.setOnGroupExpandListener(new OnGroupExpandListener() {

    public void onGroupExpand(int groupPosition) {
        int len = mAdapter.getGroupCount();

        for(int i=0; i<len; i++) {
            if(i != groupPosition) {
                list.collapseGroup(i);
            }
        }
    }

});
