This is Animation wrapping Observable. You can get event Observable. And you can call animation chain more simple.
Animation bindings

using Kotlin:
compile 'com.reyurnible.rxanimation:rxanimations-kotlin:1.0.2'
- RxAnimation
- RxAnimator
in Java
TextView textView = (TextView) findViewById(R.id.textView);
Animation animation = new ScaleAnimation(0.0f, 0.0f, 1.0f, 1.0f);
RxAnimation.events(animation, textView)
.subscribe(new Subscriber<AnimationEvent>() {
@Override public void onCompleted() {
}
@Override public void onError(Throwable e) {
}
@Override public void onNext(AnimationEvent animationEvent) {
switch (animationEvent.kind()) {
case START:
break;
case REPEAT:
break;
case END:
break;
}
}
});
in Kotlin
val view: TextView = findViewById(R.id.textView) as TextView
val animation: Animation = ScaleAnimation(0.0f, 0.0f, 1.0f, 1.0f)
animation.bindView(view).subscribe(object : Subscriber<AnimationEvent>() {
override fun onCompleted() {
}
override fun onNext(t: AnimationEvent?) {
when(t!!.kind()) {
AnimationEvent.Kind.START -> {
// START
}
AnimationEvent.Kind.END -> {
// END
}
AnimationEvent.Kind.REPEAT -> {
// REPEAT
}
}
}
override fun onError(e: Throwable?) {
}
})
private fun startAnimations() {
val alphaAnimation: AlphaAnimation = AlphaAnimation(0.0f, 1.0f)
alphaAnimation.duration = 3000
val alphaAnimationObserver = alphaAnimation.bindView(formLayout).map {
Log.d(TAG, it.toString())
it.kind() == AnimationEvent.Kind.END
}
val translationAnimator: ObjectAnimator = ObjectAnimator.ofFloat(formLayout, "translationY", -1000f, 0f);
translationAnimator.setDuration(3000);
val translateAnimatorObserver = translationAnimator.bind().map {

}
Observable.combineLatest(translateAnimatorObserver, alphaAnimationObserver, { t1, t2 ->

Log.d(TAG, "T2:" + t2.toString())
t1.and(t2)
}).filter { it }.subscribe { validate ->
// post event
