今天看到一个ios写的图灵机器人，直接去官网（http://www.tuling123.com/openapi/）看了下API接入，太简单了，就一个get请求~于是乎，写了一个Android版本的机器人，没什么技术含量，但是挺好玩的~刚好昨晚看了自己喜欢的秦时明月，嘿嘿，小貔貅，就是我的机器人宠物啦~
先看看效果图：
当然不仅是闲聊，还有更强大的，见下图：
好了，效果图就先这样了，有兴趣的自己去研究下，还支持自动学习噢 ~
下面开始代码了~
主界面消息的显示是一个ListView，不过这个listView中的Item有两种风格，一个是左边的绿色消息，一个是右边的白色消息
左边的消息布局文件：
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>就是ListView和下面的消息框和消息按钮了~没撒好说的

基本上也就完工了，没啥技术含量，纯属娱乐，各位程序猿兄，没事可以花点时间写下玩一玩~劳逸结合下~
