Question

我正在努力：

显示联系人列表
让用户通过输入查询来搜索它们
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，这会显示手机上所有帐户的搜索结果。

注意：如果我使用Contacts.CONTENT_URI而非Contacts.CONTENT_FILTER_URI，则指定目录/帐户按预期工作，但我不能再使用'type-to-filter '风格搜索。

documentation确实声明：

目录最重要的用例是搜索。目录预计提供商至少应支持Contacts.CONTENT_FILTER_URI。

任何人都可以帮助指出我可能做错了吗？

我在Google's example for contact retrieving中添加了您的代码，并通过一些更改与Google for Work帐户完美配合。

我所做的改变是：

删除DIRECTORY_PARAM_KEY行，因为我没有发现它有任何区别
从return语句中删除了ContactsQuery.SELECTION，因为该常量可以防止显示“隐身”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;
}
