Question

I want to know, If Android Supports MVC (Model View Controller) structure ? If support then
1. What is Controller ?
2.What is Model ? and
3. What is View ?

Please clear me. I have some confusion about this.

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.

So, Pseudo MVC in android :

Model = Entities or Classes with main Business Logic

View = layout, resources and widgets like EditText

Controller = Activity , Adaptor
