Question

            <Button id="button" layoutX="691.0" layoutY="305.0" mnemonicParsing="false" onAction="#btn_startmes" prefHeight="34.0" prefWidth="115.0" text="%start" />

@FXML      
private void btn_stopmes(ActionEvent event) {
  MotionCFp Stopping = new MotionCFp();
Stopping.animation.stop();
}  

motioncfp.java：

    @Override
    public void start(final Stage stage) throws Exception {
       else{
        ResourceBundle motionCFp = ResourceBundle.getBundle("motionc.fp.Bundle", new Locale("en", "EN"));
        AnchorPane root = (AnchorPane) FXMLLoader.load(MotionCFp.class.getResource("gui.fxml"), motionCFp);
        final guiController gui = new guiController();
        Scene scene = new Scene(root);
        stage.setTitle(motionCFp.getString("title"));
        stage.setResizable(false);
        stage.setScene(scene);        
        root.getChildren().add(gui.createChart());
                animation = new Timeline();
                animation.getKeyFrames().add(new KeyFrame(Duration.millis(1000/60), new EventHandler<ActionEvent>() {
            @Override public void handle(ActionEvent actionEvent) {
                // 6 minutes data per frame
                for(int count=0; count < 6; count++) {
                    gui.nextTime();
                    gui.plotTime();
                    animation.pause();
                    animation.play();
                }
            }
        }));
        animation.setCycleCount(Animation.INDEFINITE);
        stage.show();
        animation.play();
       } 

   }

您需要的是控制器中对应用程序的start方法中创建的原始动画的引用。这将允许您在控制器中编写按钮事件处理程序以停止动画。

MotionCFP类可以包含以下代码：

final FXMLLoader loader = new FXMLLoader(
  getClass().getResource("gui.fxml"), 
  ResourceBundle.getBundle("motionc.fp.Bundle", new Locale("en", "EN"))
);
final Pane root = (Pane) loader.load();
final GuiController controller = loader.<GuiController>getController();
...
animation = new Timeline();
controller.setAnimation(animation);

Guicontroller类可以包含以下代码：

private Timeline animation;

public void setAnimation(Timeline animation) {
  this.animation = animation;
}

@FXML private void btn_stopmes(ActionEvent event) {
  if (animation != null) {
    animation.stop();
  }
}
