Binding an RxJava Observable to a TextView's text property

Is there a way, perhaps using RxBinding, to bind an Observable<String> to a TextView object such that its .text property is kept up to date with the Observable? Obviously, you could subscribe() and manually update the text field, but a convenience method seems likely. I just can't find it, and the documentation hasn't yielded any answers for me.

A similar convenience method exists in RxSwift (or rather RxCocoa), in case that clarifies what I am asking for; it's called .bindTo() there.

Yes methods like this is presented in rx-binding library. For example for TextView RxTextView.text(textView) creates action which can be used as subscriber.

See source code

Usage would be something like this

observable.subscribe(RxTextView.text(textView), Throwable::printStackTrace);

Be careful with memory and read docs:

Warning: The created observable keeps a strong reference to view. Unsubscribe to free this reference.

It is not the same as bindTo magic but doing what you need.
