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

Android app on Google Play

Add RxAnimation library via Gradle:

implementation 'com.mikhaellopez:rxanimation:0.0.6'

KOTLIN

sample

  • Animate your views and handle it in Completable. For example alpha() and resize():
view1.alpha(1f)
    .andThen(view2.resize(100, 100))


sample

  • 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)
)

sample

  • 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)
)

sample

  • 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)

sample

  • You can also use the range() function to animate a change on a custom property:
(4f, 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()
