android - ARCore AnchorNode.setOnTapListener

Question

我正在尝试将 onTapListener 添加到节点，但从未调用其中的代码。有人可以发现我正在做的错误吗？

private fun addNodeToScene(fragment: ArFragment, createAnchor: Anchor, renderable: ModelRenderable) {
    val anchorNode = AnchorNode(createAnchor)
    anchorNode.setOnTapListener{_,_ ->
        buttonasd.text = "asdasd" // this line is never called
    }

    val transformableNode = TransformableNode(fragment.transformationSystem)
    transformableNode.renderable = renderable
    transformableNode.setParent(anchorNode)
    fragment.arSceneView.scene.addChild(anchorNode)
    transformableNode.select()
}

要使其正常工作，您应该执行以下操作:

    private fun addNodeToScene(fragment: ArFragment, createAnchor: Anchor, renderable: ModelRenderable) {
    val anchorNode = AnchorNode(createAnchor)

    val transformableNode = TransformableNode(fragment.transformationSystem).apply {
        setOnTapListener { _, _ ->
            //TODO your action
            }

        }
        transformableNode.localPosition = Vector3(0f,0.3f,0f)
        transformableNode.renderable = renderable
        transformableNode.setParent(anchorNode)
        fragment.arSceneView.scene.addChild(anchorNode)
        transformableNode.select()
    }
