移动应用开发 第5讲 Activity课堂综合练习

作业总要求
使用附件“素材”压缩包中的素材完成下列任务：

1.完成小游戏主程序，如图mainActivity.png。

2.在主程序界面当按下游戏介绍按钮时进行游戏介绍界面如图gameintroduce.png，按“返回”按钮则回到主程序界面。

3.在主程序界面按下“进入游戏”按钮则进入游戏界面如图gameScores.png，按“返回”按钮加回主界面同时将子程序界面中的游戏成绩返回到主程序并显示在主程序中如图mainActivity1.png所示。

4.提交程序运行视频
5.所有相关的Java和XML文件。

思路：

一个主页面，四个子页面
