非常感谢CSDN博客上的鸿洋哥,他贴出的源码是我所做的工作的基础,鸿洋哥博客链接http://blog.csdn.net/lmj623565791/article/details/38498353
下面入正题:
Android智能机器人的实现
效果图
一、概述
所谓实现了Android智能服务机器人,只是实现了一个可以调用图灵机器人API的工具,并为其加上聊天背景的壳子。
二、知识点补充(小白必看)
1.LayoutInflater:
它的作用类似于findViewById()。不同点是LayoutInflater是用来找res/layout/下的xml布局文件,并且实例化;而findViewById()是找xml布局文件下的具体widget控件(如Button、TextView等),具体作用:a、对于一个没有被载入或者想要动态载入的界面,都需要使用LayoutInflater.inflate()来载入;b、对于一个已经载入的界面,就可以使用Activiyt.findViewById()方法来获得其中的界面元素。
2.Adapter相关内容
相关内容参见 http://blog.chinaunix.net/uid-11898547-id-3303153.html
3.URLEncoder和URLDecoder
具体参见:http://www.java3z.com/cwbwebhome/article/article2/2414.html
4.HttpURLConnection
具体参见:http://www.blogjava.net/supercrsky/articles/247449.html
5.InputStream中的read()与read()
具体参见:http://www.cnblogs.com/pengyingh/articles/2507207.html
6.Button点击事件的三种方式
具体参见:http://www.2cto.com/kf/201501/369003.html
7.handler和thread的使用
具体参见:http://blog.csdn.net/lanpy88/article/details/6659630
在此贴个主要代码:
