Answer from AI

In Android, the following design patterns are often used for the view layer:

  • MVC (Model-View-Controller) — separation into model, view, and controller. The controller handles logic and interacts with the model, while the View is responsible for display.
  • MVP (Model-View-Presenter) — the View implements an interface, the Presenter contains the logic and updates the View, which facilitates testing.
  • MVVM (Model-View-ViewModel) — the ViewModel connects the model and View through data binding, simplifying UI updates.

For example, in MVP, the Presenter receives data from the model and updates the View through an interface, reducing component coupling and improving code maintainability.
