andorid里的手势电话学习（下）
说好的昨晚把自己写的代码挂出来，最后还是有事没时间挂，其实我的代码也是参考GestureBuilder和上篇的那个手势电话写的，功能差不多，只是我是通过画图查询得到名字再访问通讯录，先上下图
color.xml，string.xml很简单
1 <?xml version="1.0" encoding="utf-8"?> 2 <resources> 3 <drawable name="darkgray">#808080</drawable> 4 <drawable name="white">#FFFFFF</drawable> 5 <drawable name="blue">#0000FF</drawable> 6 </resources>
View Code
1、ECMA新增标准
2、Git远程仓库
3、06-图
4、PowerDesigner（3）---转载
5、程序员喝酒喝出的计算机文化

布局文件就不上了，都差不多。把我写的java挂出来吧
