MVC pattern on Android

Is it possible to implement the model–view–controller pattern in Java for Android?

Or is it already implemented through Activities? Or is there a better way to implement the MVC pattern for Android?

There is no universally unique MVC pattern. MVC is a concept rather than a solid programming framework. You can implement your own MVC on any platform. As long as you stick to the following basic idea, you are implementing MVC:

• Model: What to render
• View: How to render
• Controller: Events, user input

Also think about it this way: When you program your model, the model should not need to worry about the rendering (or platform specific code). The model would say to the view, I don’t care if your rendering is Android or iOS or Windows Phone, this is what I need you to render.
The view would only handle the platform-specific rendering code.

This is particularly useful when you use Mono to share the model in order to develop cross-platform applications.
