猜拳小游戏

实现界面是这样的：

 

点击下面的3个按钮是自己出拳。左边是系统随机出拳。猜拳结显示在按钮上面。

 

游戏实现很重要。这个游戏以显示为主，我在显示游戏图片的地方叠加imageview，当要显示其中一张时，其他的隐藏。

 

实现步骤：

1.布置界面。

想好界面中，你要放些什么，具体放在哪个位置。在一个xml文件中设置好。

在这个界面中，用的是相对布局，文字显示都是textview，图片是imageview，再加3个按钮。

2.响应事件

xml文件中哪些控件是需要事件响应的。在Activity中实例化，并处理相应事件。

在游戏中，根据显示的图片，判断谁赢，然后在中间的textview中显示。

 

游戏的逻辑简单，以下是代码，如果你有更简单的方法，期待你的留言。
