Data Binding observables and Kotlin
// with just a simple extension function for the Data Binding ObservableField
inline fun <R> ObservableField<R>.observe(crossinline callback: (R) -> Unit) {
this.addOnPropertyChangedCallback(object : Observable.OnPropertyChangedCallback() {
override fun onPropertyChanged(p0: Observable?, p1: Int) {
callback(get())
}
})
}
...

viewModel.user.observe {
//TODO use whatever with the observed data
}
