单击 myButton 后，运行 2 个线程。首先更改按钮图像，第二个 - 循环。我希望我的程序首先更改图像并在运行循环之后。但这不行，他们一瞬间就完蛋了。

myButton.setOnMouseClicked(event -> {
            if (event.getButton() == MouseButton.PRIMARY) {
                Thread thread = new Thread(new Runnable() {
                    @Override
                    public void run() {
                        ImageView imageView = new ImageView(image);
                        imageView.setFitHeight(my_button_height - 16);
                        imageView.setFitWidth(my_button_width - 16);
                        myButton.setStyle("-fx-background-color: #ffffff00; ");
                        myButton.setGraphic(imageView);
                    }
                });
                thread.run();
                try {
                    thread.join();
                } catch (InterruptedException e) {
                    throw new RuntimeException(e);
                }
                Thread thread1 = new Thread(new Runnable() {
                    @Override
                    public void run() {
                        for (int i = 0; i < 15; i++){
                            System.out.println(i);
                            try {
                                Thread.sleep(500);
                            } catch (InterruptedException e) {
                                throw new RuntimeException(e);
                            }
                        }
                    }
                });
                thread1.run();
            }
        });
    }

我尝试添加.join。这没有帮助
