AggregationSuggestions
java.lang.Object
android.provider.ContactsContract.Contacts.AggregationSuggestions
Class Overview
A read-only sub-directory of a single contact aggregate that contains all aggregation suggestions (other contacts).
The aggregation suggestions are computed based on approximate data matches with this contact.
Note: this query may be expensive! If you need to use it in bulk,
make sure the user experience is acceptable when the query runs for a long time.
它能查询建议和contactId合成一组的Contacts集合。
注意1:查询结果不包括其本身。
注意2:该查询很耗时。
注意3:这里查询返回的结果也是17列,和Contact一样。具体可以参照《Contact类》
例1:
Uri uri = Contacts.CONTENT_URI.buildUpon()
.appendEncodedPath(String.valueOf(
.appendPath(Contacts.AggregationSuggestions.CONTENT_DIRECTORY)
.appendQueryParameter("limit", "3")//这里限定了返回的最大项数
.build();
Cursor c = context.getContentResolver().query(uri,
new String[] {Contacts.DISPLAY_NAME, Contacts._ID, Contacts.LOOKUP_KEY},
null, null, null);
