使用ContentProvider获取联系人的所有信息

主要是用ContactsContract中的Data数据模型，该数据模型中存储了联系人的所有信息，包括：号码、姓名、Email、邮编、即时通讯账户、个性签名、昵称、个人网站等等，其实Data就是数据库中的一张表而已，该表中有一个比较重要的列叫做：MIMETYPE，有关MIMETYPE与Data的介绍，请看下面的链接，有3篇文章，讲得还可以http://www.cnblogs.com/3dant/archive/2010/12/08/1900634.html
下面就直接贴例子吧

在获取IM即时通讯信息的时候，我没有找到如何获取通讯类型的方法，但是每一种类型对应一个固定的数值，具体可以看官方文档。如果有哪位大虾知道，请告知，谢谢！！
