android - Start motion scene programmatically

Question

I have a motion layout with this layoutDescription: 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>

I think that the xml of view_home_card_start and view_home_card_end is irrelevant.

How can I call this animation programatically?

Answer 1

Finally Im doing this:

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