推荐答案

这个正在为我工​​作

expandList.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
        @Override
        public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {

            if (!parent.isGroupExpanded(groupPosition)) {
                parent.expandGroup(groupPosition);
            } else {
                parent.collapseGroup(groupPosition);
            }
            parent.setSelectedGroup(groupPosition);

            return true;
        }
    });

滚动的主要工作部分是

parent.setSelectedGroup(groupPosition);

这可以解决您的问题.
