使用CursorLoader获得接触导致的重复 [英] Using CursorLoader to get contacts causes duplication

问题描述

我建设，我想填充有电话号码的联系人的活动。

I am building an activity which I want to populate with contacts that have telephone numbers.

我不使用的意图，因为我希望这是我的列表视图每个接触前的复选框。

I am not using an Intent because I want there to be a checkbox before each contact in my listview.

我使用CursorLoader。下面是从onCreateLoader方法有些code;

I am using CursorLoader. Here is some code from the onCreateLoader method;

String projection[] = new String[]{ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME};
    Uri uri = ContactsContract.Data.CONTENT_URI;

    String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1" + 
    " AND " + ContactsContract.Contacts.IN_VISIBLE_GROUP + " =1";

    String order = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

    CursorLoader loader = new CursorLoader(this, uri, projection, selection, null, order);

我用ResourceCursorAdapter的子类，我的ListView。

I use a subclass of ResourceCursorAdapter with my ListView.

有没有人有任何想法我如何删除重复？我不想使用一组，除非我真的不得不这样做。

Does anyone have any ideas how I remove the duplicates? I don't want to use a Set unless I really have to.

推荐答案

我会建议查询联系人表，而不是原始的数据表。

I would recommend querying the Contacts table as opposed to the raw Data table.

Uri uri = ContactsContract.Contacts.CONTENT_URI;

在数据表中包含原始联系人数据，这可能意味着多个条目相同的人，因为Android的联系人来自多个不同帐户来源汇总。其他一切都看起来很好。

The data table contains raw contact data, which can mean multiple entries for the same "person" since Android contacts are aggregated from multiple different account sources. Everything else looks fine.
