android 获取手机通讯录联系人，模拟通讯录显示

最近做项目，恰好有这样的需求；在网上搜搜，找到了许多相关的文章，但是多多少少有一些出入。现在整理一下，做个总结；有疑问可以@我！主要是获取手机通讯录，模拟手机通讯录的搜索、字母排序显示；

思路：

获取手机通讯录信息，对联系人名称进行处理，获取拼音、大写字母    

详情可以参考：http://blog.youkuaiyun.com/csh159/article/details/8955029/

直接上代码

汉字转换为拼音，使用pinyin4j-2.5.0.jar库；之前使用的CharacterParser工具库是有bug的，例如“斐”是解析不出来的；
