Android 联系人合同查询列'；显示#u name'；不存在

我正在尝试使用游标加载程序获取设备中有电话号码的联系人列表，如下所示：

@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    return new CursorLoader(getActivity(), ContactsContract.CommonDataKinds.Phone.CONTENT_URI, new String[] {
            Contacts._ID, Contacts.DISPLAY_NAME }, null, null, Contacts.DISPLAY_NAME);
}

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
    mAdapter.swapCursor(cursor);
}

@Override
public void onLoaderReset(Loader<Cursor> loader) {
    mAdapter.swapCursor(null);
}

}

下面是我看到的错误：

我通常不喜欢回答自己的问题，但我最终还是找到了解决问题的办法

在同样的活动中，我有另一个片段也实现了

LoaderCallbacks

，并且我没有两个游标的唯一id。我在这个片段中得到了一个错误加载程序的游标

我认为，因为它们位于两个不同的片段中，永远不会同时可见，所以我不需要唯一的ID，但这是不正确的
