Démarrer la scène animée par programme

J'ai une disposition de mouvement avec cette disposition Description: 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>

Je pense que le xml de view_home_card_start et view_home_card_end n'est pas pertinent.

Comment puis-je appeler cette animation par programmation?

Enfin je fais cela:

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

In Latest Update of Constraint **2.0.0-beta1** Layout There are Public methods add in motion layout 
        you can get these methods with the help of motionlayout id 
    **motionLayout** 

     1. public void setProgress (float pos) 
     2. public void setTransition (int
           beginId,int endId)  
     3. public void setTransitionDuration (int
               milliseconds)  public void setTransitionListener
               (MotionLayout.TransitionListener listener)

     4. public void setState (int
               id,int screenWidth, 
                             int screenHeight)

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