android - 使用listview加载不同item，数据填充错误。

当日期的值为空的时候，就会将姓名或邮箱等值填充进去，当日期有值的时候现实正常，找了好久不知道怎么搞，希望各位大神给点建议。

下面为adapter的代码：

private static final int TYPE_VIEW_COUNT = 2;
private static final int TYPE_ONE = 0;
private static final int TYPE_TWO = 1;

private List mDatas;
private Context mContext;
private LayoutInflater mInflater;

private int eventIds = -1;
private int attendIds = -1;
private int ticketIds = -1;
private Attends attends;
private EventTicket ticket;
private JSONObject object = null;

public DetailAdapter(List mDatas, Context mContext, int eventId, int attendId, int ticketId) {
    this.mDatas = mDatas;
    this.mContext = mContext;
    this.mInflater = LayoutInflater.from(mContext);
    this.eventIds = eventId;
    this.attendIds = attendId;
    this.ticketIds = ticketId;
    
    attends = new Select().from(Attends.class).where(Attends_Table.eventId.is(eventIds)).and(Attends_Table.attendId.is(attendIds)).querySingle();
    ticket = new Select().from(EventTicket.class).where(EventTicket_Table.eventIds.is(eventIds)).and(Attends_Table.ticketIds.is(ticketIds)).querySingle();

    try {
        object = new JSONObject(attends.gsonUser);
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

@Override
public int getItemViewType(int position) {
    if (position == 0) {
        return TYPE_ONE;
    } else {
        return TYPE_TWO;
    }
}

@Override
public int getViewTypeCount() {
    return TYPE_VIEW_COUNT;
}

@Override

    return mDatas.size() + 1;
