当我在自定义的 MotionLayout 中滚动时在 textview 中调整大小
Resize in textview when I scroll in customized MotionLayout

CollapsibleToolbar 正在扩展 MotionLayout：
class CollapsibleToolbar @JvmOverloads constructor(
context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : MotionLayout(context, attrs, defStyleAttr), AppBarLayout.OnOffsetChangedListener {
override fun onOffsetChanged(appBarLayout: AppBarLayout?, verticalOffset: Int) {
progress = -verticalOffset / appBarLayout?.totalScrollRange?.toFloat()!!
}
override fun onAttachedToWindow() {
super.onAttachedToWindow()
(parent as? AppBarLayout)?.addOnOffsetChangedListener(this)
}
}

当我开始在 PersonActivity 中滚动时，角色名称会调整大小并显示为下图：
我应该怎么做才能让 name 的初始大小作为 motionLayout 开始滚动的初始大小？我应该在此处进行任何更改吗：
