Android 2.0 How to get display name and number in a contact group

Question

I get a list of contacts in a given group id by id

Cursor cur = ctx.managedQuery(ContactsContract.Data.CONTENT_URI, new String[] { GroupMembership.GROUP_ROW_ID, GroupMembership.CONTACT_ID }, GroupMembership.GROUP_ROW_ID + "=" + String.valueOf(id), null, null);

if (cur.moveToFirst()) { int groupIdx = cur.getColumnIndex(GroupMembership.GROUP_ROW_ID); int personIdx = cur.getColumnIndex(GroupMembership.CONTACT_ID);

do {
    if (cur.getLong(groupIdx) == id) {
        Cursor ccur = ctx.getContentResolver().query( Phone.CONTENT_URI,
            new String[] {Phone.NUMBER, Phone.TYPE,
            Phone.DISPLAY_NAME },
            Phone.CONTACT_ID +"="+ contactId, 
                  null, null); 
        Log.e("Test: Number", ccur.getString(0))
        Log.e("Test: Name", ccur.getString(2))
    }
} while (cur.moveToNext());

}

but it seems that does not work correctly. Any help?

Probably you are missing the mimetype.

String where = ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID + "="
                + groupid + " AND "
                + ContactsContract.CommonDataKinds.GroupMembership.MIMETYPE + "='"
                + ContactsContract.CommonDataKinds.GroupMembership.CONTENT_ITEM_TYPE + "'";

        Cursor c = this.ctx.getContentResolver().query(
                ContactsContract.Data.CONTENT_URI,
                new String[] {
                        ContactsContract.CommonDataKinds.GroupMembership.RAW_CONTACT_ID,
                        ContactsContract.Data.DISPLAY_NAME
                }, where, null, ContactsContract.Data.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
