Kotlin for cleaner ViewModels

[manas-chaudhari]

Add a kotlin artifact android-mvvm-kotlin with convenient extension functions for converting between Fields and Observables

[mishkaowner]

fun <T> ObservableField<T>.toObservable(): Observable<T> = Observable.create { e ->
    val initialValue = [email protected]()
    if (initialValue != null) {
        e.onNext(initialValue)
    }
    val callback = object : OnPropertyChangedCallback() {
        override fun onPropertyChanged(observable: android.databinding.Observable, i: Int) {
            e.onNext([email protected]())
        }
    }
    [email protected](callback)
    e.setCancellable { [email protected](callback) }
}

? Something like this?

You can use the FieldUtils.toObservable inside the extension function. The code doesn't need to be repeated.

fun <T> ObservableField<T>.toObservable(): Observable<T> = FieldUtils.toObservable(this)

What... I didn't know that...
