为什么我在Java FX中没有得到任何缩放转换

Question

我一直在尝试使用JavaFx为imageView获取Scale Transition。我写的代码似乎很好。但当我运行这个代码时，我没有得到任何过渡效果，也没有错误，图像保持在其各自的位置。有人能帮我吗？？？

在下面的代码中，我想为图像resumeBtn进行比例转换。

import java.io.IOException;
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.input.KeyEvent;
import javafx.stage.Stage;
public class TryFXML extends Application{
@Override
public void start(Stage stage) throws IOException  {
// TODO Auto-generated method stub
try {
Parent root = FXMLLoader.load(getClass().getResource("PauseScreen.fxml"));
Scene scene=new Scene(root);
stage.setScene(scene);
stage.setTitle("Pause Screen");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}


stage.show();
}

public static void main(String[] args) {
launch(args);
}
}

我的控制器类：

import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Node;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TitledPane;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.KeyCode;
import javafx.scene.input.KeyEvent;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.Pane;
import javafx.scene.shape.Circle;
import javafx.stage.Stage;
import javafx.util.Duration;
import java.io.IOException;
import java.net.URL;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import javax.annotation.Resource;
import javafx.animation.AnimationTimer;
import javafx.animation.ScaleTransition;
import javafx.event.ActionEvent;
public class TimeController {



@FXML
private ImageView resumeBtn;
@FXML
private ImageView restartBtn;
@FXML
private ImageView saveBtn;




@FXML
public void initialize(Stage stage) throws IOException {



ScaleTransition rsm=new ScaleTransition(Duration.seconds(5),resumeBtn);
rsm.setAutoReverse(true);
rsm.setCycleCount(1000);
rsm.setFromX(1);
rsm.setToX(4);
rsm.setFromY(1);
rsm.setToY(4);
rsm.play();


}



@FXML
void restartClicked(MouseEvent event) {
System.out.println("you clicked here 1");
}

@FXML
void saveClicked(MouseEvent event) {
System.out.println("You clicked here 2");
}
}

我的FXML代码：：

来自javafx.fxml.Initializable:的文档

FXMLLoader现在将自动调用控制器定义的任何适当注释的无参数initialize()方法。

请注意no arg部分。您需要定义一个接受零参数的initialize()方法。您当前的initialize方法不符合规定的要求，因此永远不会调用它。

更改此项：

public void initialize(Stage stage) throws IOException {

到此：

public void initialize() throws IOException {
