获取具有类型到过滤功能的Android联系人,仅限特定帐户

Question

我试着:

• 显示联系人列表
• 让用户通过键入查询来搜索它们
• 仅将搜索结果限制为特定的Google/Gmail帐户.

---

这是我为游标构建URI的方法:

// User is searching for 'jo'
String query = "jo";
Uri uri = Uri.withAppendedPath(Contacts.CONTENT_FILTER_URI, Uri.encode(query));

// Restrict the query to contacts from 'example@gmail.com'
Uri.Builder builder = uri.buildUpon();
builder.appendQueryParameter(
    ContactsContract.DIRECTORY_PARAM_KEY, String.valueOf(ContactsContract.Directory.DEFAULT));
builder.appendQueryParameter(ContactsContract.RawContacts.ACCOUNT_NAME, "example@gmail.com");
builder.appendQueryParameter(ContactsContract.RawContacts.ACCOUNT_TYPE, "com.google");

uri = builder.build();

这是最终的URI:

content://com.android.contacts/contacts/filter/jo?directory=0&account_name=example%40gmail.com&account_type=com.google

目前,这显示了手机上所有帐户的搜索结果.

注意:如果我使用Contacts.CONTENT_URI而不是Contacts.CONTENT_FILTER_URI,则指定目录/帐户按预期工作,但我不能再使用"类型到过滤器"样式搜索.

该文件确实状态:

目录最重要的用例是搜索.目录提供商预计至少会支持Contacts.CONTENT_FILTER_URI.

任何人都可以帮助指出我可能做错了什么吗？

我在Google 的联系人检索示例中添加了您的代码，经过一些更改，它与我的 Google for Work 帐户完美配合。

我所做的改变是：

• 删除 行DIRECTORY_PARAM_KEY，因为我发现它没有任何区别
• 从 return 语句中删除ContactsQuery.SELECTION，因为该常量会阻止显示“不可见”联系人。

对ContactsListFragment.java进行了更改

@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    // If this is the loader for finding contacts in the Contacts Provider
    // (the only one supported)
    if (id == ContactsQuery.QUERY_ID) {
        Uri contentUri;

        // There are two types of searches, one which displays all contacts and
        // one which filters contacts by a search query. If mSearchTerm is set
        // then a search query has been entered and the latter should be used.

        if (mSearchTerm == null) {
            // Since there's no search string, use the content URI that searches the entire
            // Contacts table
            contentUri = ContactsQuery.CONTENT_URI;
        } else {
            // Since there's a search string, use the special content Uri that searches the
            // Contacts table. The URI consists of a base Uri and the search string.
            contentUri = Uri.withAppendedPath(ContactsQuery.FILTER_URI, Uri.encode(mSearchTerm));
        }

        // HERE COMES YOUR CODE (except the DIRECTORY_PARAM_KEY line)
        Uri.Builder builder = contentUri.buildUpon();
        builder.appendQueryParameter(ContactsContract.RawContacts.ACCOUNT_NAME, "example@mycompany.com");
        builder.appendQueryParameter(ContactsContract.RawContacts.ACCOUNT_TYPE, "com.google");
        contentUri = builder.build();

        // Returns a new CursorLoader for querying the Contacts table. No arguments are used
        // for the selection clause. The search string is either encoded onto the content URI,
        // or no contacts search string is used. The other search criteria are constants. See
        // the ContactsQuery interface.

        return new CursorLoader(getActivity(),
                contentUri,
                ContactsQuery.PROJECTION,
                null, // I REMOVED SELECTION HERE
                null,
                ContactsQuery.SORT_ORDER);
    }

    Log.e(TAG, "onCreateLoader - incorrect ID provided (" + id + ")");
    return null;
}
