How to structure layers in Clean Architecture for implementing an interface that interacts with API and displays a list of items?

Answer from AI
In Clean Architecture, layers are separated by responsibility:
- Entity — business models, for example, the
Itemclass. - Use Cases — business logic, such as fetching a list of items from an API.
- Interface Adapters — data transformation for UI, including Presenters and ViewModels.
- Frameworks & Drivers — UI, network, implementation of API requests and display.
For an interface that interacts with an API and displays a list of items, the structure might be:
- Entity:
Itemmodel. - Use Case:
GetItemsUseCaseclass, which requests data from the repository. - Repository Interface: defines methods for data retrieval.
- Data Layer: repository implementation that calls the API.
- Presentation Layer: ViewModel or Presenter that calls the Use Case and prepares data for UI.
- UI Layer: Activity/Fragment or Composable that displays the list.
An example of a simplified chain:
UI -> ViewModel -> GetItemsUseCase -> Repository -> API
This separation ensures the business logic is independent of API and UI implementation details.
