完善登录注册页面

实验内容

综合运用基本组件完成一个注册与登录的应用程序设计。要求基于基础控件，综合使用Intent实现Android的Activity之间信息交换。系统包含启动页、注册页、登录页3个页面，具体要求如下：

在第2周上机作业的基础上，完善登录注册页面。

1.注册页面和功能的实现。

界面除用户名、密码、确认密码之外，增加性别(单选按钮)、学历(spinner)、爱好(复选框)等信息。

使用相对布局。

2.登陆页面和功能的实现。

要求使用Shape和Selector对页面进行美化。按第3章的课件中的提示可完成。

附件内容包括一张用于启动页的图片，2张用于编辑框美化的背景图片。
