How to disable elements in expandablelistview?

I am using ExpandableListView with "groups" and "childs" elements. Is it possible to disable expanding some of group elements ? Do I need to change some code in Adapter or should I override onclick method?

Use setOnGroupClickListener on your listview and return true on the position you want to disable to be expended

this will disable the first element to be expended 

expListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
        @Override
        public boolean onGroupClick(ExpandableListView expandableListView, View view, int i, long l) {
            if (i==0){
                return true;
            }
            return false;
        }
    });

Call .setClickable(false) on those group headers that shall not trigger on click. Your adapter gets a call to getGroupView. This method returns the view that is displayed as the group header. If you don't want this view clickable, call .setClickable(false)

    @Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {

    if (convertView == null) {
        LayoutInflater li = LayoutInflater.from(activity);
        convertView = li.inflate(<<your header item>>, null);
    }

     if (isLastGroup)
        convertView.setClickable(false);

    return convertView;
}
