通过手机号来查找联系人姓名 关键字"display_name"


content://com.android.contacts/raw_contacts

添加联系人

示例:

//添加姓名
values.put("raw_contact_id", contactid);
values.put("mimetype", "vnd.android.cursor.item/name");
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", "zhangxx@youkuaiyun.com");
resolver.insert(uri, values);

withValueBackReference( String key, int previousResult)方法

第一个参数key对应于数据库中的列名，第二个参数 previousResult代表着：回引数据库批量操作中的 第previousResult个数据库操作的返回值。
总的来说就是说把批量数据库操作中的第previousResult个数据库操作的返回值作为列名为key的记录的值
