プログラムでモーションシーンを開始する

このレイアウトのモーションレイアウトがあります説明：app:layoutDescription="@xml/scene"

scene.xml

<MotionScene
    xmlns:motion="http://schemas.Android.com/apk/res-auto">

    <Transition
        motion:constraintSetStart="@layout/view_home_card_start"
        motion:constraintSetEnd="@layout/view_home_card_end"
        motion:duration="1000">
        <OnSwipe
            motion:touchAnchorId="@+id/button"
            motion:touchAnchorSide="left"
            motion:dragDirection="dragLeft" />
    </Transition>

</MotionScene>

view_home_card_startとview_home_card_endのxmlは無関係だと思います。

このアニメーションをプログラムで呼び出すにはどうすればよいですか？

最後にこれをやっています：

((MotionLayout)findViewById(R.id.motionLayout)).transitionToEnd();
((MotionLayout)findViewById(R.id.motionLayout)).transitionToStart();

     2. public void setTransition (int
           beginId,int endId)  
     3. public void setTransitionDuration (int
               milliseconds)  public void setTransitionListener

     5. if(wantShowUi)
            {
                newUserActivityBinding.coordinatorLayout.transitionToStart();
            }
            else
            {
                newUserActivityBinding.coordinatorLayout.transitionToEnd();
