可扩展列表视图给出了错误的组位置，只有在没有视图持有者的情

我无法在不使用视图持有者模式的情况下继续操作，但因为我在每个列表中都运行倒计时，并且Expandablelistview在没有它的情况下变得不稳定。也许这是一个简单的修复。提前致谢。 

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

    final ViewHolderItem viewHolder;

    if (convertView == null) {

        LayoutInflater infalInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = infalInflater.inflate(R.layout.item_lobby, null);
        viewHolder = new ViewHolderItem();

        viewHolder.lobbyItemExpandIndicator = (ImageView) convertView.findViewById(R.id.lobbyItemExpandIndicator);
        viewHolder.draftEnding = (TextView) convertView.findViewById(R.id.lobbyDraftEnding);
        viewHolder.gameType = (TextView) convertView.findViewById(R.id.lobbyGameType);
        viewHolder.accepting = (TextView) convertView.findViewById(R.id.lobbyAccepting);
        viewHolder.gamesInDraft = (TextView) convertView.findViewById(R.id.lobbyGamesInDraft);

        //viewHolder.draftEnding.setText(groupPosition + "");


        convertView.setTag(viewHolder);
    } else {


        viewHolder = (ViewHolderItem) convertView.getTag();
    }

    final ContestItem contest =  mContests.get(groupPosition);

    //setCountdown(viewHolder, contest);


    viewHolder.gameType.setText(contest.getGameType());
    viewHolder.accepting.setText(contest.getAccepting());
    viewHolder.gamesInDraft.setText(contest.getNbaGamesAmnt());

    if (isExpanded) {
        viewHolder.lobbyItemExpandIndicator.setImageResource(R.drawable.w_dash);
    } else {
        viewHolder.lobbyItemExpandIndicator.setImageResource(R.drawable.w_down);
    }

    return convertView;
}

static class ViewHolderItem {
    TextView draftEnding;
    TextView gameType;
    TextView accepting;
    TextView gamesInDraft;
    ImageView lobbyItemExpandIndicator;
}

您应该将您的倒计时保留在组模型对象中而不是保留在视图中，每次都会重复使用视图。所以你必须在你的小组模型中保持倒计时，然后每次都进行视图恢复倒计时。

例如，如果您的显示数据是：

> dput(sample(d$Lat, 10))
structure(c(174L, 7L, 185L, 121L, 127L, 200L, 121L, 62L, 64L, 
191L), .Label = c("", "0°18'22<U+2033> N", "0°31'30<U+2033> S", 
"0°53'15<U+2033> N", "0°54'00<U+2033> S", "1°17'26<U+2033> N",

然后你必须将你的倒计时保持在private HashMap<MenuCategoryModel, List<ChildCategoryModel>> mMainMenuExpandableList; 或者如果每个子项目都在MenuCategoryModel以及获取视图组或孩子（无论需要什么） - 还原倒计时。
