使用ConstraintSet的ConstraintLayout动画不适用于ScrollView

标签： android android-animation android-constraintlayout constraintset

我有两个带有ConstraintLayout的布局，它有一个子NestedScrollview，而NestedScrollview又有一个子ConstraintLayout作为容器，而不是其他视图。我想使用ConstraintSet设置两个布局的动画，但是不幸的是，这不起作用。另一方面，如果我删除NestedScrollview和根ConstraintLayout，则它可以正常工作。我想用NestedScrollview或Scroll view实现此任务吗？提前致谢。 这是我的代码
