动画视图宽度

ObjectAnimator 随着 AnimatorSet

extension 在里面 kotlin 对于 view 要在其上应用动画。

inline fun View.animateWidth(duration: Long = 1000, startDelay: Long = 0) {
    val scaleX = ObjectAnimator.ofFloat(this, "scaleX", /*Change width*/)
    //val scaleY = ObjectAnimator.ofFloat(this, "scaleY", /*Change width*/)
    val set = AnimatorSet()
    //set.playTogether(scaleX, scaleY)
    set.playTogether(scaleX)
    set.duration = duration
    set.startDelay = startDelay
    set.interpolator = LinearInterpolator()
    set.addAnimatorListener(
            onStart = { this.isClickable = false },
            onEnd = { this.isClickable = true }
    )
    set.start()
}
