RxView.bindView(View view, Observable<T> source)

[passsy]

When I updated to RxAndroid 1.0.0 I missed ViewObservable.bindView(View view, Observable<T> source). Will it be added here? Is there another way I'm not seeing to replace this API?

https://github.com/ReactiveX/RxAndroid/blob/4bff437edfa24dde62c90d44b019b9a35855db6a/rxandroid/src/main/java/rx/android/view/ViewObservable.java

I often used a combination of this to attach observables to items in my adapters.

ViewObservable.bindView(myView, Observable.interval(500, TimeUnit.MILLISECONDS))
        .subscribe(/* do something with myView */);

Manually unsubscribing looks like unnecessary extra effort.

This library is for property and event binding only. That method was an analogous to the poorly-named bindActivity or bindFragment but for views which relate to the lifecycle of these objects and thus firmly outside the scope of this library.

Once view attach/detach events are added you'll be able to use this library to compose operators to a functionally-equivalent solution along the lines of:

Observable.interval(500, MILLISECONDS)
    .takeUntil(RxView.attachEvents(myView).filter(e -> e.kind() == DETACH))
    .subscribe(/* do something with myView */);

This can easily be abstracted into a static helper method of the same signature as the ViewObservable.bindView method.

I really like the view attach/detach event solution! Are these events planned for the near future?

[JakeWharton]

Yep. They're on my list (which I should probably move to GitHub issues).

Talked with @dlew and he agreed it fits within the scope of RxLifecycle, pull request here: trello-archive/RxLifecycle#12

On a related note, some of the event names/usage overlap (like attach/detach). @JakeWharton @dlew any interest in maybe consolidating these in some way so users don't end up with duplicates?

Even better!

API in 1.0.1-SNAPSHOT:

Observable.interval(500, MILLISECONDS)
    .takeUntil(RxView.detaches(myView))
    .subscribe(/* do something with myView */);
