Basic example for AndroidReactComponentKit :)

Actions

data class ClickButtonAction(val message: String): Action

State

sealed class Route {
    object None: Route()
    data class Alert(val message: String): Route()
}

data class MainState(
    val route: Route = Route.None
): State() {
    override fun copyState(): State {
        return this.copy()
    }
}

MainViewModel & Define Flow

class MainViewModel(application: Application): RCKViewModel<MainState>(application) {

    val route = Output<Route>(Route.None)

    override fun setupStore() {

        initStore { store ->
            store.initialState(MainState())

            store.flow<ClickButtonAction>(
                { state, action ->
                    state.copy(route = Route.Alert(action.message))
                }
            )
        }

    }

    override fun on(newState: MainState) {
        route.accept(newState.route).afterReset(Route.None)
    }
}

MainActivity

class MainActivity : AppCompatActivity() {

    private lateinit var viewModel: MainViewModel
    private val disposeBag: AutoDisposeBag by lazy {
        AutoDisposeBag(this)
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        viewModel = ViewModelProviders.of(this).get(MainViewModel::class.java)

        verticalLayout {
            lparams(matchParent, matchParent)
            gravity = Gravity.CENTER
            component(ButtonComponent(viewModel.token))
        }

        handleViewModelOutputs()
    }

    private fun handleViewModelOutputs() {
        viewModel
            .route
            .asObservable()
            .skip(1)
            .subscribe {
                handleRoute(it)
            }
            .disposedBy(disposeBag)
    }

    private fun handleRoute(route: Route) {
        when(route) {
            is Route.Alert -> {
                alert(route.message).show()
            }
            else -> Unit
        }
    }
}

Button Component

class ButtonComponent(token: Token): ViewComponent(token) {
    private lateinit var button: Button

    override fun layout(ui: org.jetbrains.anko.AnkoContext<Context>): View = with(ui) {
        val layout = relativeLayout {
            lparams(wrapContent, wrapContent)
            button = button("Click Me")
        }

        button.setOnClickListener {
            dispatch(ClickButtonAction("Hello AndroidReactComponentKit :)"))
        }

        return layout
    }
}
