content://com.android.contacts/contacts

对应数据库表中contacts表用于获得联系人Id 关键字"_id"

content://com.android.contacts/contacts/"+ contactid+ "/data

对应data表通过contactId来查找联系人的各项属性 (data1属性值 data2属性的类型(如家庭电话手机)) 关键字"mimetype","data1","data2"

"content://com.android.contacts/data/phones/filter/"+ number

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Emailvalues.clear();values.put("raw_contact_id", contactid);values.put("mimetype", "vnd.android.cursor.item/email_v2");values.put("data2", "2");values.put("data1", "zhangxx@csdn.net");resolver.insert(uri, values);

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

，待人对事不要太计较，如果太计较就会有悔恨！
