How to check if group is expanded or collapsed in Android ExpandableListView?

Question

I\'m looking for an api like isExpanded() or isCollapsed() that tell me if a group is expanded or collapsed.

Answer 1

As @George D wrote there is ExpandableListView .isGroupExpanded(int groupPosition) method. Well you could add the code to get expanded group position or -1

public int getExpandedGroupPosition() {
    for (int i = 0; i < listView.getExpandableListAdapter().getGroupCount(); i++) {
        if ( listView.isGroupExpanded(i) ) {
            return i;
        }
    }

    return -1;
}
