如何在Android中设置动画速度

Question

我有一组动画，我发现每个片段启动时速度都很快，如何调整执行速度？

我尝试了这个，但动画太快了

val animator1 = ObjectAnimator
            .ofFloat(binding.logoAnimated,
                "translationX", 0f, -(width - point.x)).apply {
                repeatCount = 1
                repeatMode = ValueAnimator.REVERSE
            }

        val animator2 = ObjectAnimator
            .ofFloat(binding.logoAnimated,"translationX",
                0f, +(width - point.x)).apply {
                repeatCount = 1
                repeatMode = ValueAnimator.REVERSE
            }

        val animatorSet = AnimatorSet()
        animatorSet.playSequentially(animator1, animator2)
        animatorSet.start()

您可以通过ObjectAnimator调整动画的执行速度，您可以设置每个ObjectAnimator实例的

duration

属性。该属性决定动画需要多长时间才能完成（以毫秒为单位）

val duration = 2000L // 2000 milliseconds = 2 second


val animator1 = ObjectAnimator
    .ofFloat(binding.logoAnimated, "translationX", 0f, -(width - point.x))
    .apply {
        this.duration = duration  // Set duration for animator1
        repeatCount = 1
        repeatMode = ValueAnimator.REVERSE
    }

val animator2 = ObjectAnimator
    .ofFloat(binding.logoAnimated, "translationX", 0f, +(width - point.x))
    .apply {
        this.duration = duration  // Set duration for animator2
        repeatCount = 1
        repeatMode = ValueAnimator.REVERSE
    }


val animatorSet = AnimatorSet()
animatorSet.playSequentially(animator1, animator2)
animatorSet.start()
