我将ConstraintLayout用作父布局和set android:animateLayoutChanges="true"。当更改某些嵌套视图的可见性时，我将其用作其他视图背景的图层（androidx.constraintlayout.helper.widget.Layer）展示出来了。没有android：animateLayoutChanges就可以了。
我还尝试了“组”小部件的requestLaout()方法中的post()（指的是用于显示/隐藏操作的嵌套视图）-> group.post { binding.bg.parent.requestLayout() }，它可以工作。但是这样一来，Layer会在短时间后显示，我不希望这种隐藏和显示发生。
这是我的XML文件：
