我有一个JavaFX要从 迁移Java 8到的应用程序Java 11，这是一个粗略的过渡，但除了 之外，大多数应用程序都在工作web service，它一直给我一个例外：

我是新手motionlayout，一直在关注像这样的各种在线教程，以了解它是如何工作的。简而言之，我已经知道它基本上是动画的constraintSets，你有一个start和end constraintSet，你可以用它进一步定制KeyFrameSets。我有这个布局

我想模仿Lyft's bottom sheet

根据我的布局，Where are you going按钮应该随着搜索目的地textInputs淡入而慢慢淡出。recyclerview底部的应该保持保存addresses，它不会受到影响。我尝试使用标准实现此实现bottomsheet，但在动画方面遇到了挑战，它很奇怪，flickering所以我决定使用MotionLayout普通视图。

我的bottomsheet布局如下

<com.google.android.material.card.MaterialCardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:id="@+id/cardChooseAddressBottomSheet"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clickable="true"
    app:shapeAppearance="@style/ShapeAppearanceRoundedLargeTopCorners">



    <androidx.constraintlayout.widget.ConstraintLayout
        android:id="@+id/bottomSheetConstraintLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="@dimen/activity_horizontal_margin"
        android:layout_marginRight="@dimen/activity_horizontal_margin"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">



        <ImageView
            android:id="@+id/swipeUpHandle"
            android:layout_width="50dp"
            android:layout_height="30dp"
            android:layout_gravity="center"
            android:background="@drawable/ic_swipe_up_handle"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />



        <com.google.android.material.textview.MaterialTextView
