转载，该博客写的比较简单明了了，记录一下

        binding.sendRoot.apply {
            val transitioner = LayoutTransition()

            transitioner.setAnimator(
                LayoutTransition.APPEARING, ObjectAnimator.ofFloat(
                    null, "translationX", -126.dpf, 0f
                ).setDuration(250)
            )
            transitioner.setAnimator(
                LayoutTransition.DISAPPEARING, ObjectAnimator.ofFloat(
                    null, "translationX", 0f, (-126).dpf
                ).setDuration(250)
            )
            transitioner.setStagger(LayoutTransition.CHANGE_APPEARING, 250)
            transitioner.setStagger(LayoutTransition.CHANGE_DISAPPEARING, 250)
            transitioner.setStagger(LayoutTransition.CHANGING, 250)
            layoutTransition = transitioner
        }
