This is an Android library to make a simple way to animate your views on Android with Rx.

Add RxAnimation library under Rx3 with Gradle:

implementation 'com.mikhaellopez:rxanimation:2.1.1'

:warning: If you use Rx2 you need to implement the following version (just on jcenter):

implementation 'com.mikhaellopez:rxanimation:1.0.0'

KOTLIN

• Animate your views and handle it in Completable. For example alpha() and resize():

view1.alpha(1f)
    .andThen(view2.resize(100, 100))

• If you want to apply animation in the same time you can used RxAnimation.together():

RxAnimation.together(
    view1.fadeIn(),
    view1.translation(20f, 30f),
    view2.backgroundColor(
        ContextCompat.getColor(this, R.color.accent),
        ContextCompat.getColor(this, R.color.primary)
    ),
    view2.resize(100, 100)
)

• If you want to apply animation one by one you can used RxAnimation.sequentially() instead of multi andThen():

RxAnimation.sequentially(
    view1.fadeIn(),
    view1.translation(20f, 30f),
    view2.backgroundColor(
        ContextCompat.getColor(this, R.color.accent),
        ContextCompat.getColor(this, R.color.primary)
    ),
    view2.resize(100, 100)
)

• You can also used RxAnimation.from(view) if you want to update multi properties one by one in the same view:

RxAnimation.from(view)
    .fadeIn()
    .translation(20f, 30f)
    .backgroundColor(
        ContextCompat.getColor(this, R.color.accent),
        ContextCompat.getColor(this, R.color.primary)
    )
    .resize(100, 100)

• You can also use the range() function to animate a change on a custom property:

(4f to 20f).rangeFloatToCompletable { 
    circularImageView.borderWidth = it 
}

// or

RxAnimation.from(circularImageView)
    .rangeFloat(4f, 20f) { circularImageView?.borderWidth = it }

• Use reverse properties to back to the initial value in all methods:

view.fadeIn(reverse = true)

• If you want to repeat an animation you can use the native method repeat from Rx like this:

RxAnimation.from(view)
    .fadeIn()
    .shake()
    .fadeOut()
    .repeat(NB_REPEAT)
    .subscribe()
