OmegaMoxy

Moxy is a library that helps to use MVP pattern when you do the Android Application. Without problems of lifecycle and boilerplate code!

The main idea of using Moxy: See what's happening here in the wiki.

Capabilities

Moxy has a few killer features in other ways:

Presenter stay alive when Activity recreated(it simplify work with multithreading)
Automatically restore all that user see when Activity recreated(including dynamic content is added)
Capability to changes of many Views from one Presenter

Sample

View interface

interface HelloWorldView: MvpView {

    var waiting: Boolean

    @MoxyViewCommand(ONE_EXECUTION)
    fun showMessage(int message)

}

Presenter

class HelloWorldPresenter: MvpPresenter<HelloWorldView> {

    init {
        viewState.showMessage(R.string.hello_world)
    }

}

View implementation

class HelloWorldActivity: MvpAppCompatActivity, HelloWorldView {

    private val helloWorldPresenter: HelloWorldPresenter by providePresenter {
        HelloWorldPresenter()
    }

    private lateinit var helloWorldTextView: TextView

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_hello_world)

	helloWorldTextView = findViewById<TextView>(R.id.activity_hello_world_text_view_message)
    }

    @Override
    override fun showMessage(message: Int) {
        helloWorldTextView.setText(message)
    }
}

Here you can see "Github" sample application.
