感谢这两位的博客:
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：

}经过了手机测试成功，代码比较臃肿，还没有实现输入筛选条件查询，正在研究中
