        ImageView firstImage = new ImageView();
        firstImage.setImage(first);


        Image second = new Image("http://hq-wallpapers.ru/wallpapers/2/hq-wallpapers_ru_animals_8040_1280x1024.jpg", 100.0, 100.0, true, true);

        secondImage.setImage(second);

        secondImage.setLayoutX(150);
        secondImage.setLayoutY(150);


        group.getChildren().add(firstImage);
        group.getChildren().add(secondImage);


        Scene scene = new Scene(group, 300, 300);
        stage.setScene(scene);
        stage.show();


        ScaleTransition ft = new ScaleTransition(Duration.millis(3000));
        ft.setByX(1.5);
        ft.setByY(1.5);
        ft.setNode(firstImage);
        ft.play();


        ScaleTransition st = new ScaleTransition(Duration.millis(3000));
        st.setNode(secondImage);
        st.setByX(1.5);
        st.setByY(1.5);
        st.play();




    }
}

这只是简单的代码示例。

我需要一个接一个地做动画。

动画优先 超时 3 秒。 动画秒。

我该怎么做？

最大的问题是如何在主线程的不同部分之间暂停。

Answer 1

要一个接一个地制作动画，请将它们放入SequentialTransition：

ScaleTransition ft = new ScaleTransition(Duration.millis(3000));
ft.setByX(1.5);
ft.setByY(1.5);
ft.setNode(firstImage);

ScaleTransition st = new ScaleTransition(Duration.millis(3000));
st.setNode(secondImage);
st.setByX(1.5);
st.setByY(1.5);

SequentialTransition sequence = new SequentialTransition(ft, st);
sequence.play();

如果您需要它们之间的实际差距，您可以添加PauseTransition，例如

PauseTransition pause = new PauseTransition(Duration.seconds(1));

SequentialTransition sequence = new SequentialTransition(ft, pause, st);
sequence.play();
