values.put("data2", "张小小");
resolver.insert(uri, values);
//添加电话
values.clear();
values.put("raw_contact_id", contactid);
values.put("mimetype", "vnd.android.cursor.item/phone_v2");
values.put("data2", "2");
values.put("data1", "13671323507");
resolver.insert(uri, values);
//添加Email
values.clear();
values.put("raw_contact_id", contactid);
values.put("mimetype", "vnd.android.cursor.item/email_v2");
values.put("data2", "2");
values.put("data1", "[email protected]");
resolver.insert(uri, values);
