⚠️ Deprecated

CheeseWire is deprecated. From Android Gradle Plugin 3.6 on, you should use ViewBinding.

CheeseWire

Lifecycle-friendly view binding in Kotlin for Conductor.

To use, add a ConductorViewBinder to your base controller:

abstract class BaseController : Controller() {
  protected val views = ConductorViewBinder(this)
}

This can now be used to bind views in your concrete controllers:

class HomeController : BaseController() {
  private val btnLogin: Button by views.bind(R.id.btn_login)
}

during onDestroyView, the view binder is reset, and your views aren't leaked.

See the sample app for an example.

Generic lazy

CheeseWire view binders also provide a generic lazy property delegate which is synchronized with your view property lifecycle. This comes in handy e.g. in combination with RxBinding when you want to avoid calling the RxBinding methods twice on a view:

class MyMviController : BaseController() {
  private val btnLogin: Button by views.bind(R.id.btn_login)
  private val btnSignup: Button by views.bind(R.id.btn_login)

  val intentions by views.lazy {
    Observable.merge(
        btnLogin.clicks().map { Intention.Login },
        btnSignup.clicks().map { Intention.Signup }
    )
  }
}
