我的adapter里面传入一个list，初始化的时候是对的，当我切换不同日期的数据，从数据库中获取，想要显示在上面时，却乱序了。

数据库中获取的数据没错，我把获取的list覆盖了本来的list，更新时有数据，但是是错乱重复的，不同月份信息还混在了一起

public void notifyListDateDataChanged(List<BillDetail> newBillDetailsList){
    this.mBillDetailsList.clear();
    this.mBillDetailsList.addAll(newBillDetailsList);
    for (int i = 0; i <mBillDetailsList.size(); i++) {
        Log.d(TAG, "notifyListDateDataChanged: 第"+i+":"+mBillDetailsList.get(i).get_id());
    }
    notifyDataSetChanged();
}

上面代码是外部传入list更改数据用的，有没有大神踩过这个坑，求助，是我理解的不对吗
