android - 使用listview加载不同item，数据填充错误。

Question

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<FormData> 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<FormData> 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
public int getCount() {
    return mDatas.size() + 1;
}

@Override
public Object getItem(int position) {
    return mDatas.get(position);

@Override

    return position;

                userDetailViewHolder.tv_detail_name = (TextView) convertView.findViewById(R.id.tv_detail_name);
                userDetailViewHolder.tv_ticket_name = (TextView) convertView.findViewById(R.id.tv_detail_ticket);
                convertView.setTag(userDetailViewHolder);
             //   AutoUtils.auto(convertView);
                break;
            case TYPE_TWO:
                holder = new DetailViewHolder();
                convertView = mInflater.inflate(R.layout.attend_people_datail_type2, null);
                holder.tv_form = (TextView) convertView.findViewById(R.id.tv_form);

                break;
            case TYPE_TWO:
                holder = (DetailViewHolder) convertView.getTag();
                break;
        }
    }
    //根据返回类型展示不同的数据
    switch (viewTypeCount) {

        case TYPE_ONE:
            if (attends != null && ticket != null) {
                userDetailViewHolder.tv_name_letter.setText(attends.names.substring(0, 1));
                userDetailViewHolder.tv_detail_name.setText(attends.names);
                userDetailViewHolder.tv_ticket_name.setText(ticket.ticketNames);
            }
            break;
        case TYPE_TWO:
            if (position >= 1) {
                Log.e("", "position -->" + position);

                    holder.tv_form.setText(mDatas.get(position - 1).getFormName());
                    try {
                        if (object != null) {
                            holder.tv_detail_content.setText(object.getString(mDatas.get(position - 1).getFormFieldId() + ""));
                        }
                        //  Toast.makeText(mContext, holder.tv_form.getText().toString(), Toast.LENGTH_LONG).show();
                      //  Toast.makeText(mContext, holder.tv_detail_content.getText().toString(), Toast.LENGTH_LONG).show();
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            }
            break;
    }

    return convertView;
}

class DetailViewHolder {
    TextView tv_form;
