Hey there!
I'm querying the ContactsContract.Data table like the following:
[...]
Uri contactsURI = ContactsContract.Data.CONTENT_URI;
String[] projection = new String[] {
ContactsContract.Data._ID,
ContactsContract.Data.CONTACT_ID,
ContactsContract.Data.MIMETYPE,
ContactsContract.Data.DATA1,
ContactsContract.Data.DATA2,
ContactsContract.Data.DATA3,
ContactsContract.Data.DATA4,
ContactsContract.Data.DATA5,
ContactsContract.Data.DATA_VERSION
};
String where = ContactsContract.Data.MIMETYPE + " = ?
OR " +
ContactsContract.Data.MIMETYPE + " = ?
OR " +
ContactsContract.Data.MIMETYPE + " = ?
OR " +
ContactsContract.Data.MIMETYPE + " = ?";
String[] whereArgs = new String[] {
ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,
ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,
ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE,
ContactsContract.CommonDataKinds.Im.CONTENT_ITEM_TYPE
};
Cursor contactsTable = managedQuery(contactsURI, projection,
where, whereArgs, null);
[...]
The problem is that the result is kind of unsorted. It would be best
if I could get the rows sorted by MIMETYPE (basically I need the
StructuredName to come on top) but grouped for each CONTACT_ID. This
means I'd like to get a person's name, then email/phone/im, etc. Then
the next person's name and their email/phone/im and so on..
So I thought this would best be achieved if I sorted like
Data.MIMETYPE + " DESC" and group by CONTACT_ID. However, there is no
possibility to use a group by parameter in a query() or managedQuery
(). The only database query I found that does take a group by
parameter is the SQLiteQueryBuilder.query(). However, I can't call
this one for the ContactsContract.Data Table since it doesn't take an
URI but an SQLiteDatabase.
How would you handle the sorting of the data? Should I perform a
single query for each CONTACT_ID? Wouldn't that be extremely cost
intensive?
