Coroutines Animations

Use the power of kotlin coroutines to execute your android animations

implementation 'com.github.florent37:coroutine-animations:(last version)'

Usage

TOTO : ADD VIDEO

launch(UI) {
    //fire an alpha animation without suspending coroutine
    animation(avatar) { alpha = 0.5f } 
 
    //execute a translation animation
    //use .join() to suspend the coroutine until the animation end
    animation(avatar, startDelay = 1000L) { y = 0f }.join()
 
    //run these animations in parallel
    mutableListOf<Job>(
           animation(follow) {
               top = avatar.y + avatar.height + 16f
           },
           animation(kotlin) {
               left = avatar.x - kotlin.width - 16f
               centerY = avatar.centerY()
           }
    )
    .forEach { it.join() } //wait until all animations have finished
}

Simple animation

animation(view, startDelay= , duration=, interpolator=) { 
    property1 = value1 
    property2 = value1 
}

Custom animation

Animation of Float values

floatAnimation(avatar, from=1f, to=0.5f){ view, value ->
    view.alpha = value
}

Animation of Int values

intAnimation(avatar, from=0, to=300){ view, value ->
    view.x = value
}

Chain Animations

.join() suspend the coroutine until the animation has finished

animation(view1) { property1 = value1 }.join()
animation(view2) { property2 = value2 }.join()

Animations in parallel

Just use animations as usual coroutine jobs, if you want to wait for multiple to finish, add them into a list and call join on each

val animations = mutableListOf<Job>(
    animation(view1) { property1 = value1 }
    animation(view2) { property2 = value2 }
)
animations.forEach { it.join() } // wait for all animations to complete
