Question

由于某些原因，我的expandableListView在Scroll或旋转更改时崩溃。我有两个此活动的视图类型

代码：

    @Override
    public int getGroupType(int groupPosition){
        return comments.get(groupPosition).is_load_more;
    }

    @Override
    public int getGroupTypeCount(){
        return 2;
    }

    @Override
    public View getGroupView(final int groupPosition, boolean isExpanded,  View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        View vi = convertView;
        final commentItem item = getGroup(groupPosition);
        if(vi == null) {
            holder = new ViewHolder();
            if(getGroupType(groupPosition) == 1){
                vi = mLayoutInflater.inflate(R.layout.comments_loadmore, null);
                holder.load_more = (Button)vi.findViewById(R.id.comments_load_more);
            }else{
                vi = mLayoutInflater.inflate(R.layout.comments_item, null);
                holder.aq = new AQuery(vi);
                holder.usericon = (ImageView)vi.findViewById(R.id.comments_item_userpic);
                holder.username = (TextView)vi.findViewById(R.id.comments_item_username);
                holder.fullname = (TextView)vi.findViewById(R.id.comments_item_fullname);
                holder.content = (TextView)vi.findViewById(R.id.comments_item_content);
                holder.commentc = (TextView)vi.findViewById(R.id.comments_item_commentcount);
                holder.commentBtn = (FrameLayout)vi.findViewById(R.id.comments_item_comment);
                holder.bumpBtn = (ImageView)vi.findViewById(R.id.comments_item_bump);
                holder.bumpc = (TextView)vi.findViewById(R.id.comments_item_countbump);
                holder.replyLayout = (LinearLayout)vi.findViewById(R.id.comments_item_replyLayout);
            }

        } else {
            holder = (ViewHolder) vi.getTag();
        }

        if(getGroupType(groupPosition) == 1){

        }else{
            holder.aq.id(R.id.comments_item_userpic).image(item.user_img, true, false, 96, 0);

logcat的：

它崩溃在“holder.aq.id（R.id.comments_item_userpic）.image（item.user_img，true，false，96,0）;”而且我不知道为什么。有谁可以帮助我？

Answer 1

我忘了添加 vi.setTag（保持器）; 在我第一次设置视图持有者之后。我的坏：希望这有助于任何有类似问题的人

具有多个视图类型的ExpandableListView在Scroll等上崩溃
