模仿微信好友列表功能(数据从手机中读取)，实现汉首字母排序筛选：
用到了一个pinyin4j-2.5.0.jar这个包
?
这个包的介绍:http://sourceforge.net/projects/pinyin4j/files/
?
其中还有一个 ContentResolver的知识点：
http://www.cnblogs.com/ruiyi1987/archive/2011/06/20/2084925.html
?
这篇文章中用到这样一个查询条件：
? String[]?proj1=new?String[]{ContactsContract.Contacts.DISPLAY_NAME,
????????????????????????????????????ContactsContract.Contacts.HAS_PHONE_NUMBER,
????????????????????????????????????ContactsContract.Contacts.LOOKUP_KEY};
ContactsContract.Contacts已经不推荐使用，现在推荐使用phone
?
下面是代码：
