1、概要
这个作品有五个界面：首页、登录、注册、好友、聊天。实现了一些简易的功能，连接服务器进行登录和注册功能，显示了好友列表，借鉴别人的聊天页面。
试运行用户：
用户名：123
密码： 123
2、首页界面、
在这个页面进行应用打开缓冲，根据登录状态信息判断进行页面跳转，未登录-》登录界面、登录-》好友界面。
3、 登录界面
在这个界面进行登录信息输入，连接服务器验证信息，正确跳转到好友界面，并存储登录信息和状态，下次打开应用不必登录，错误进行提醒。如果无账号，点击新用户，进入注册页面
4、注册界面
该页面进行注册功能，连接服务器，进行注册，注册成功进入登录界面，也可以点击返回，返回登录界面
5、好友界面
显示好友消息，好友消息，如果不退出登录，下次打开应用进入此界面。点击退出登录，会清除登录信息，点击好友进入聊天页面。
6、聊天界面
该页面进行聊天，可发送字符和表情，未连接服务器。点击返回键返回好友界面。
