Android通讯录管理一之联系人获取

标签：android   联系人   通讯   

正如我们知道的一样，Android的通讯录和短信管理是通过contentprovider来向开发者来开发接口的。必须从ContentResolver入手去解决。其中通讯录操作涉及到系统源码api的使用，特别是在表的uri上面容易弄混。在接下来的几篇文章中蜗牛将陆续为大家推出Android通讯管理相关知识的文章。其中包括联系人获取、通话记录获取、短信获取、短信详情获取发送短信。废话不多说先上图

先看看联系人的表的结构

其中对于开发这来说主要关注以上三个表，其中要用到联合查询，关于三张表的设计可以百度到相关文章。
