AndroidReactComponentKit

AndroidReactComponentKit is ReactComponentKit for Android. AndroidReactComponentKit is a library for building Activity or Fragment. You can make that based on Components. Also, It uses MVVM and Redux architectures for unidirectional data flow.

Data Flow

• (1) : Components dispatch actions
• (2) : ViewModel passes the actions to the store. You can use beforeDispatch(action:) method to do some work before dispatching actions.
• (3) : Store passes current state to the Mutation pipeline. Reducers make a new state.
• (4) : New State comes out from the Mutation pipeline. It is passed to the store.
• (5) : Store passes the new state to the ViewModel.
• (6) : ViewModel passes the new state to the Components.

Components

AndroidReactComponentKit provides four components basically.

• ViewComponent
  • ViewComponent is a view. It is an abstraction of the view that makes up the screen as a component. You can use ViewComponent to create a layout of the Activity or Fragment. It can also be used to create an item views in RecyclerView.
• FragmentComponent
  • FragmentComponet is a fragment. You can use FragmentComponent when creating an Activity. If you delegate responsibility for an Activity to a FragmentComponent, you can avoid creating a massive Activity.
• RecyclerViewAdapter
  • The RecyclerViewAdapter connects ViewComponent and RecyclerView. The RecyclerViewAdapter can use several types of views, but only one LayoutManager can be used.
• CollectionViewAdapter
  • The CollectionViewAdapter connects ViewComponent and RecyclerView. Unlike the RecyclerViewAdapter, you can use multiple LayoutManagers. In other words, you can use various LayoutManagers with different types of views.
