MVP, MVVM, and MVC are architectural patterns that help organize application code by separating logic, presentation, and data.

  • MVC (Model-View-Controller): The Model contains data and business logic, the View is responsible for display, and the Controller handles user input and updates the model and view. The Controller interacts directly with the model and view.

  • MVP (Model-View-Presenter): Similar to MVC, but the Controller is replaced by a Presenter, which contains all the interaction logic between the Model and the View. The View is passive and interacts only with the Presenter through an interface.

  • MVVM (Model-View-ViewModel): The Model is data, the View is UI, and the ViewModel is an abstraction of the view that contains UI logic and state. The ViewModel binds to the View through data binding, reducing the need for code to update the UI.

In Android:

  • MVC is rarely used due to the tight coupling between View and Controller.
  • MVP is often used for testability, as the Presenter is easy to test.
  • MVVM became popular with the advent of Android Data Binding and Jetpack ViewModel, simplifying UI updates when data changes.
