Android机器人对话实现
一、主要内容：
（1）使用图灵机器人对话
http://www.tuling123.com/
注册后，选用自定义，新建机器人。将第三方jar包引入AndroidStudio
· 将jar文件复制、粘贴到app的libs目录中
· 右键点击jar文件，并点击弹出菜单中的“Add As Library”，将jar文件作为类库添加到项目中；
· 选择指定的类库。
注：如果不执行2、3步，jar文件将不起作用，并且不能使用import语句引用。将第三方so文件引入AndroidStudio
· 在“src/main”目录中新建名为“jniLibs”的目录；
· 将so文件复制、粘贴到“jniLibs”目录内。相关文章链接：

（2）ListView中item不同布局的实现
