android - Android 是否支持 MVC(Model View Controller)结构？

Question

我想知道，Android是否支持MVC(Model View Controller)结构？如果支持的话1.什么是 Controller ？2.什么是模型？和3.什么是 View ？

请清除我。我对此有些困惑。

Answer 1

Which design patterns are used on Android?

Model-View-Control works fine

The actual Activity class doesn't extend android's View class, but it does, however, handle displaying a window to the user and also handle the events of that window (onCreate, onPause etc).

This means, that when you are using a MVC pattern, your controller will actually be a pseudo View-Controller. Since it is handling displaying a window to the user, with the additional view components you have added to it with setContentView, and also handling events for atleast the various activity life cycle events.

In MVC, the controller is supposed to be the main entry point. Which is a bit debatable if this is the case when applying it to android development, since the activity is the natural entry point of most applications.

因此，android 中的伪 MVC:

模型 = 具有主要业务逻辑的实体或类

View = 布局、资源和小部件，如 EditText

Controller = Activity , 适配器
