推荐答案

在这种情况下使用 listener 是很常见的方法:

Using a listener is quite common approach in such situation:

private Node getModel() {
    Node node = new Node();
    node.setRenderable(modelRenderable);
    Context cont = this;
    node.setOnTapListener((v, event) -> {
        Toast.makeText(
            cont, "Model was touched", Toast.LENGTH_LONG)   // Toast Notification 
            .show();
    });
    return node;
}
