Start motion scene programmatically

Question

I have a motion layout with this layoutDescription: app:layoutDescription=\"@xml/scene\"

scene.xml

Answer 1

If anyone's doing this from a fragment:

1. Import:

   import androidx.constraintlayout.motion.widget.MotionLayout;
   

2. Instantiate MotionLayout:

   MotionLayout motionLayout = view.findViewById(R.id.your_motion_layout);
   

3. Transition to the end/start of motion:

   motionLayout.transitionToStart();
   

or

    motionLayout.transitionToEnd();
