图灵智能对话机器人DEMO

PS:

目前还有点bug，会继续修正

存在问题：当对话到达30个或以上只删除了机器人的消息。

bug已经修正

设计步骤：

1、main布局和头像+对话框布局

2、得到EditView得到用户输入的信息并通过点击发送按钮，触发onClick事件，此处分为2部分：

【1】通过HttpClient的httpGet，采用异步任务AsyncTask，并将得到的数据传回MainActivity并进行解析。

【2】数据存在lists中

3、异步任务AsyncTask如何进行：见文章链接点击打开链接

4、在ListAdapter的设置方面：

【1】首先需要通过LayoutInflater.from(mContext)先获得实例inflater，然后通过inflater.inflate()得到需要载入的界面；

【2】判断是机器人还是用户，数据显示在屏幕上。

5、数据的封装

_补充————bug修正————————

出现bug原因：ArrayList 删除问题

正序遍历删除

* 结果：只删除了一半

* 原因：每删除一个，size变小，要删除下一个前需移一位，下次相当于是隔一个再删除

改成：倒序遍历删除（每次都删除最后一个）就可以了。

if (lists.size() > 30) {
for (int i =lists.size()-6; i >= 0; i--) {
lists.remove(i);
}
}
