The MVP (Model View Presenter) architecture pattern is widely adopted in Android development for structuring application code into separate layers that enhance maintainability, readability, and scalability. This approach involves three distinct components: Model, View, and Presenter. By GeeksforGeeks.
The Model component focuses on data storage and handles domain logic while managing communication with databases or networks. The View layer is responsible for displaying data and tracking user actions to notify the Presenter. The Presenter fetches data from the Model, applies UI logic, manages the state of the View, and responds to user input notifications. This separation of concerns promotes better code organization, maintainability, and testing capabilities.
To show the implementation of the MVP architecture pattern on projects, you will find an example of a single activity android application in the artivlr. The application will display some strings on the View(Activity) by doing a random selection from the Model. The role of the Presenter class is to keep the business logic of the application away from the activity. Below is the complete step-by-step implementation of this android application. Note that we are going to implement the project using both Java and Kotlin language.
The MVP architecture’s key points include communication via an interface between the View-Presenter, Presenter-Model components, ensuring each component has a one-to-one relationship without knowledge of the others’ existence. This structure facilitates independent development and maintenance of each layer while promoting modularity, testability, and clean codebase. Good read!
