为什么我在 Java FX 中没有得到任何比例转换。？

Question

我一直在尝试使用 Java Fx 对 imageView 进行缩放转换。我写的代码似乎没问题。但是当我运行这段代码时，我没有得到任何过渡效果，也没有错误，图像停留在其各自的位置。有人可以帮帮我吗？？？

在下面的代码中，我想对图像 resumeBtn 进行缩放转换。

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class:

        rsm.setAutoReverse(true);
        rsm.setCycleCount(1000);
        rsm.setFromX(1);
        rsm.setToX(4);
        rsm.setFromY(1);
        rsm.setToY(4);
        rsm.play();
        
        
    }

        System.out.println("you clicked here 1");

Answer 1

来自the documentation of javafx.fxml.Initializable：

FXMLLoader will now automatically call any suitably annotated no-arg initialize() method defined by the controller.

注意 no-arg 部分。您需要定义一个接受零参数的 initialize() 方法。您当前的初始化方法不符合规定的要求，因此永远不会被调用。

改变这个：

public void initialize(Stage stage) throws IOException {

对此：

public void initialize() throws IOException {
