今天我上传下我期末时候的Android作品，包含代码和运行结果

1)编码实现“登录界面”。

• 界面实现，添加事件，当密码不一致时，弹出相应的对话框“两次密码不一致，请重试！”。
• 当单击“提交”按纽，先验证用户密码正确，再实现页面跳转到主界面。

2)实现“主界面”。

• 实现图3所示的界面，利用GridView+（SimpleAdapter、baseAdapter任一）实现。
• 添加事件监听，当单击“新闻”数据项时，跳转到新闻界面。当单击“个人”数据项时，跳转到个人界面。

3)实现“个人信息”界面。

• 实现界面。
• 当单击“选择地区”，Spinner组件会显示相关内容，要求结合ArrayAdapter适配器来实现，提交  数组资源文件及Spinner结合ArrayAdapter使用的代码。
•  按“提交”按纽，跳转到“结果界面”, 注意要用Bundle数据包来存储数据，并用Intent进行页面跳转。

1. 实现“结果”界面。

• 在“个人信息”界面中，当单击“提交”时，将页面输入的内容显示到“结果界面”,如图7所示。
• 在“结果”界面上，按“返回”，则关闭此界面，返回“个人信息”界面上。

5)实现“新闻”界面。

• 为文本添加“上下文”菜单。
• 为“上下文”菜单添加事件，实现文字的字体大小变换，如图10所示的界面。
• 当单击“关闭”时，关闭当前界面返回到上一页面中。
