Android ExpandableListView点击列表项改变列表项内组件产生混乱的问题

Question

//ExpandableListView的适配器
@Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
GroupViewHolder gvholder;
if (convertView == null) {
gvholder = new GroupViewHolder();
convertView = LinearLayout.inflate(getBaseContext(),
R.layout.group_layout, null);
gvholder.groupcity = (TextView) convertView
.findViewById(R.id.group_title);
gvholder.groupsize = (TextView) convertView
.findViewById(R.id.groupcap);
gvholder.groupload = (ImageView) convertView
.findViewById(R.id.group_state);
convertView.setTag(gvholder);
} else {
gvholder = (GroupViewHolder) convertView.getTag();
}

// ExpandableListView 的OnGroupClick监听
allcitylists.setOnGroupClickListener(new OnGroupClickListener() {

        @Override
        public boolean onGroupClick(ExpandableListView parent, View v,
                int groupPosition, long id) {
            // TODO Auto-generated method stub
            group_checked[groupPosition] = group_checked[groupPosition] + 1;

            ((BaseExpandableListAdapter) expadapter).notifyDataSetChanged();
            if (groupPosition < 5
                    || groupPosition >= provincelist.size() - 3) {
                ArrayList<MKOLSearchRecord> records = mOffline
                        .searchCity(provincelist.get(groupPosition).get(0));

                if (records != null && records.size() == 1) {
                    cityid =

                    records.get(0).cityID;

                    mOffline.start(cityid);

                    updateView();

                //改变的组件
                    TextView loadtext = (TextView) v
                            .findViewById(R.id.group_loadtitle);
                    loadtext.setVisibility(View.VISIBLE);

                    changeloadtext(loadtext, cityid);

                }

            }
            return false;
        }
    });

    内容比较多，没贴完，但关键的地方都在上面，点击列表项能够把loadtext显示出来，但是上下滑动之后，显示的就不是我刚刚点击的那个列表项的TextView，而是其他列表项的Textview，应该是不能在这里用ViewHolder，但是我也想不出来怎么改变，请各位大神指教指教

回收机制，你上下滑动之后，最上面的item被回收了，你之前点击的那个group会被刷新，你得保存每个group被点击后的groupposition 和对应的cityid,在适配器刷新之后重新显示出来
