In one of my Android projects, I used the MVVM (Model-View-ViewModel) architecture. It helps separate presentation logic from business logic, making maintenance and testing easier.
- Model is responsible for data handling (e.g., repositories, databases).
- View consists of UI components (Activity, Fragment) that display data.
- ViewModel contains logic for preparing data for the View and interacts with the Model.
To connect the View and ViewModel, I used LiveData, which automatically updates the UI when data changes.
A simple example of a ViewModel in Kotlin:
class UserViewModel : ViewModel() {
private val userRepository = UserRepository()
val userData: LiveData<User> = userRepository.getUserLiveData()
}
This approach improves code readability and facilitates application scaling.
