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 completeHow to Contribute
