AnimationX

使用Flow封装了一套api，提供了一种简单的方法来在创建视图动画。

用法

alpha :透明度

view.run {
    launch(this.alpha(ANIMATION_DURATION, reverse = true))
}

rxLifeScope.launch {
    view.alpha(ANIMATION_DURATION, reverse = true).collect()
}

//记得在view销毁时取消， 不推荐
val job = GlobalScope.launch {
    view.alpha(ANIMATION_DURATION, reverse = true).collect()
}

job.cancel()

translation:平移

view.run {
    launch(this.translation(500f, 500f, ANIMATION_DURATION,
     reverse = true))
}

scale:缩放

view.run {
    launch(this.scale(0f, ANIMATION_DURATION, reverse = true))
}

backgroundColor：背景色

view.run {
    launch(this.backgroundColor(
        ContextCompat.getColor(this@MainActivity, R.color.primary),
        ContextCompat.getColor(this@MainActivity, R.color.accent),
        ANIMATION_DURATION, reverse = true
    ))
}

rotation：旋转

view.run {
    launch(this.rotation(360f, ANIMATION_DURATION))
}

rangeAnyToCompletable:

view.run {
    launch(this.(0f to 30f).rangeAnyToCompletable(ANIMATION_DURATION) {
        view.text = format.format(it as Float)
    })
}

reveal:揭示动画

view.run {
    launch(this.reveal(
        viewX.toInt(),
        viewY.toInt(),
        0f,
        hypot(
            this.width.toDouble(),
            this.height.toDouble()
        ).toFloat(),
        2000L
    ))
}

多个动画同时进行

AnimationX.together(
    binding.fab.rotation(360f, ANIMATION_DURATION),
    binding.text.fadeIn(ANIMATION_DURATION)
).collect()

多个动画顺序进行

AnimationX.sequentially(
    binding.cardView.scale(1f, ANIMATION_DURATION),
    binding.fab.scale(1f, ANIMATION_DURATION),
    binding.progressBar.fadeIn(ANIMATION_DURATION)
).collect()

动画结束后执行操作

view.run {
    launch(this.fadeOut().onCompletion { 
        //do something
    })
}

智能功能

fadeOut:淡出

view.run {
    launch(this.fadeOut())
}

fadeIn:淡入

view.run {
    launch(this.fadeIn())
}

shake:抖动

view.run {
    launch(this.shake())
}

press:按压

view.run {
    launch(this.press())
}

text:文字变换

testview.run {
    launch(this.text("Pateo", ANIMATION_DURATION, reverse = true))
}
