标签: java android kotlin android-constraintlayout constraintset

我想使用Contarint集更改视图可见性,创建两个相同的视图,但是在第二个视图中使视图可见性消失,实际上,当我运行活动时,它仅显示视图可见性已经消失的第二个XML,但是没有动画,它的可见性如何。

 <androidx.constraintlayout.widget.ConstraintLayout
    android:id="@+id/constraint"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white">


    <LinearLayout

        android:orientation="vertical"
        app:layout_constraintTop_toTopOf="parent">


        <TextView
