Question

我试图创建图库并使用一些图像动画。问题出在ImageView上。我希望play() RotateTransition从某种方法中随时调用此方法，但它根本不起作用。线程应该存在一些问题，但即使从新线程调用它也没有发生任何事情。是否有任何解决方案如何一般地使用ImageView和Transitions？

public class ImageGallery extends ImageView{
    RotateTransition rt;

    public ImageGallery() {
        setImage(new Image("/img/01.jpg"));
        setPreserveRatio(true);

        rt = new RotateTransition(Duration.millis(800), this);
        rt.setByAngle(90);

        //this works but not what I need 
        //fitWidthProperty().addListener(e -> rt.play()); 
    }

    public void rotateRight(){
        rt.play(); //nothing

        //run later is not working too 
        //Platform.runLater(new ViewTransition(this));
    }
}

谢谢
