RxAnimations
RxAnimations is a library with the main goal to make android animations more solid and cohesive.

RxJava version compatibility:
This RxAnimations library is only compatible with rxJava 1 greater than 1.2.x.
If you are using rxJava 1.1.x version, take a look here.
If you are searching for the one compatible with rxJava 2, take a look over here.
Usage
A sample project which provides code examples that demonstrate uses of the classes in this project is available in the sample-app/ folder.
True power of this library is the ability to use animations as an observable asynchronous action.
That enables us to apply regular rxJava APIs on the animations.
It provides a couple of classes such as RxValueAnimator, RxObservableValueAnimator and RxAnimationBuilder.
Moreover, it also provides many regulary used animation methods (static import) such as fadeIn(), fadeOut(), slideIn(), leave() etc.
Examples:
- Animating multiple views together
animateTogether(fadeIn(firstView),
fadeIn(secondView));
- Chaining multiple animations seamlessly
fadeIn(firstView)
.concatWith(fadeIn(secondView));
- Simple ValueAnimator usage with RxValueAnimator
final ValueAnimator opacityAnimator = ValueAnimator.ofFloat(0.f, 1.f);
RxValueAnimator.from(opacityAnimator, animator -> view.setAlpha((float)animator.getAnimatedValue()))
- Animating multiple values together with RxObservableValueAnimator
xObservableAnimator = RxObservableValueAnimator.from(xAnimator);
yObservableAnimator = RxObservableValueAnimator.from(yAnimator);
Observable.combineLatest(xObservableAnimator.schedule(),
yObservableAnimator.schedule(),
(first, second) -> new Pair(first, second))
.subscribe(this::updateView);
- Defining custom animations with RxAnimationBuilder
RxAnimationBuilder.animate(view, DURATION)
.interpolator(INTERPOLATOR)
.fadeIn()
.rotate(DEGREES)
.translateBy(X, Y)
...
.schedule([ | false]);
Animation created with RxAnimationBuilder automatically pretransforms the view, if not set otherwise.
I.e. if fadeIn() is called, views opacity will be set to 0.f before animation starts.
Managing animations
Starting animation - Every animation chain is started when we subscribe to it.
Ending animation - Animations can be easily stopped by unsubscribing animation subscription.
