如何使两个FXML布局响应？

我有两个不同的FXML文件和两个Controller类，其中第一个是进入第二个场景的按钮，而第二个场景中是返回第一个场景的后退按钮。如果仅加载其中一个，则布局可以调整大小，但是加载第一个FXML文件，然后单击“播放”按钮后，第二个场景的布局不响应，反之亦然。我的问题是，即使在调整窗口大小之后，如何在前进和后退时都响应这两个布局？ 

public class Main extends Application {

@Override
public void start(Stage primaryStage) throws Exception {

    try {
        FXMLLoader loader = new FXMLLoader(getClass().getResource("ViewOneScene.fxml"));
        Parent root = (Parent) loader.load();
        Scene scene = new Scene(root);
        primaryStage.setTitle("Test");
                    primaryStage.centerOnScreen();
        primaryStage.setScene(scene);
        primaryStage.show();
    } catch (Exception e) {
        e.printStackTrace();
    }


public class ViewOneController {

@FXML
private Button playButton;

@FXML
private Button optionsButton;

@FXML
private Button exitButton;

@FXML
protected void handlePlayButton(ActionEvent event) throws IOException {
    Parent root = FXMLLoader.load(getClass().getResource("ViewTwoScene.fxml"));
    Scene secondScene = new Scene(root);

    Stage stage = (Stage) ((Node) event.getSource()).getScene().getWindow();
    stage.setScene(secondScene);
    stage.show();
}
