I hope this helps . Similar to set position cornerNode.setLocalPosition(localPosition); you can set rotation cornerNode.setLocalRotation(new Quaternion(90f, 0f, 0f, -90f));

How to render a View to the right of parent node in ARCore sceneform

How to render a View to the right of parent node in ARCore sceneform

this will help Using ViewRenderable I am rendering layout file. I gave fixed width and height for the layout file , I found solution to fix the above mentioned issue that I faced.
code :
    Node node = new Node();
    node.setParent(parent);
    Renderable renderable = Meters.get(i);
    renderable.setShadowReceiver(false);
    renderable.setShadowCaster(false);
 ((ViewRenderable) renderable).setSizer(new FixedWidthViewSizer(2));
    node.setRenderable(renderable);
    node.setLocalPosition(new Vector3(2.0f, 0.0f, 0.0f));
 ((ViewRenderable) renderable).setSizer(new FixedWidthViewSizer(2));

hope this fix your issue You need to set a local scale of the node before setting its parent. The code should look like this:
code :
Anchor anchor = hitResult.createAnchor();
AnchorNode anchorNode = new AnchorNode(anchor);

node.getScaleController().setMinScale(0.5f);
node.getScaleController().setMaxScale(3.0f);

node.setLocalScale(new Vector3(2.25f, 2.25f, 2.25f));
node.setParent(anchorNode);

wish helps you I am new to sceneform sdk for Android . I have added one Transformable Node , then i applied some rotation , scaling and changed its position also. Now on click of button i need to place second node with same rotation , scaling and position.
code :
anchor = hitResult.createAnchor();
        anchorNode = new AnchorNode(anchor);
        anchorNode.setParent(arView.getArSceneView().getScene());
        transformableNode = new TransformableNode(arView.getTransformationSystem()); // As you said i have added one transformablenode which will allow transformation.
        transformableNode.setParent(anchorNode);
        transformableNode.setRenderable(modelRenderable);
        transformableNode.select();
 Node node = new Node();
        Vector3 position = transformableNode.getLocalPosition();
        Quaternion rotation = transformableNode.getLocalRotation();
        TransformableNode andyNOde = new TransformableNode(arView.getTransformationSystem());
        andyNOde.setRenderable(andyRenderable);
        andyNOde.setLocalPosition(position);
        andyNOde.setLocalRotation(rotation);
        andyNOde.setParent(node);
        anchorNode.removeChild(transformableNode);
        anchorNode.addChild(node);

hope this fix your issue on the new version of SCENEFORM SDK, v1.3.0 issue is resolved. use this in app level gradle
implementation "com.google.ar.sceneform:core:1.3.0"
How to rotate animate the rotation of a Node in ARCore Sceneform

How to rotate animate the rotation of a Node in ARCore Sceneform

Does that help The easiest way is to use the Android Property Animation. An example of doing this is in the Sceneform sample "Solar System". Take a look at RotatingNode. This rotates the node around its axis.
First, it creates an ObjectAnimator that uses LinearInterpolation to set the rotation between 4 points around a circle.
code :
private static ObjectAnimator createAnimator() {
    // Node's setLocalRotation method accepts Quaternions as parameters.
    // First, set up orientations that will animate a circle.
    Quaternion orientation1 = Quaternion.axisAngle(new Vector3(0.0f, 1.0f, 0.0f), 0);
    Quaternion orientation2 = Quaternion.axisAngle(new Vector3(0.0f, 1.0f, 0.0f), 120);
    Quaternion orientation3 = Quaternion.axisAngle(new Vector3(0.0f, 1.0f, 0.0f), 240);
    Quaternion orientation4 = Quaternion.axisAngle(new Vector3(0.0f, 1.0f, 0.0f), 360);

    ObjectAnimator orbitAnimation = new ObjectAnimator();
    orbitAnimation.setObjectValues(orientation1, orientation2, orientation3, orientation4);

    // Next, give it the localRotation property.
    orbitAnimation.setPropertyName("localRotation");

    // Use Sceneform's QuaternionEvaluator.
    orbitAnimation.setEvaluator(new QuaternionEvaluator());

    //  Allow orbitAnimation to repeat forever
    orbitAnimation.setRepeatCount(ObjectAnimator.INFINITE);
    orbitAnimation.setRepeatMode(ObjectAnimator.RESTART);
    orbitAnimation.setInterpolator(new LinearInterpolator());
    orbitAnimation.setAutoCancel(true);

    return orbitAnimation;
  }
  orbitAnimation = createAnimator();
  orbitAnimation.setTarget(this);
  orbitAnimation.setDuration(getAnimationDuration());
  orbitAnimation.start();
