Collapse all group except selected group in expandable listview android

Question

I\'m developing android application using expandable list view. Actually what I need is, I\'m listing group, which contains child.

If I select an unexpandable group

Answer 1

Try putting this in your ExpandableListAdapter, listView is a reference to the ExpandableListView itself. And lastExpandedGroupPosition is a integer member variable defined inside your ExpandableListAdapter.

 @Override
    public void onGroupExpanded(int groupPosition)

{

//collapse the old expanded group, if not the same

//as new group to expand

if(groupPosition != lastExpandedGroupPosition)

{

  listView.collapseGroup(lastExpandedGroupPosition);

  }

        super.onGroupExpanded(groupPosition);           
        lastExpandedGroupPosition = groupPosition;
    }
