问题描述

中根据应用的状态（状态机形式），用setContentView来切换各个视图，

用一个Activity对应一个界面，还是一个个自定义的View对应一个界面
从网上看到的很多例子都是：整个应用一个Activity，然后所有的界面采用自定义的派生自View的类实现，比如：MenuView、SplashView、HelpAboutView，在Activity中根据应用的状态（状态机形式），用setContentView来切换各个视图，这样就是一个View对应一个界面。还有一种写法，就是用一个Activity来对应一个界面，根据应用的状态在各个Activity间进行切换。我想问下这两种写法谁优谁劣，各有什么优点和弊端
