Question

任何帮助将不胜感激。

我正在尝试在预加载器完成其循环之后加载新的舞台或场景，但是在初始化任务并添加新的fxmlloader之后，我的代码似乎什么也没做。

我不知道还能尝试什么。

您可以看到以下代码：

class DoWork extends Task<Integer>  {
@Overrideimport java.net.URL;

protected Integer call() throws Exception{
    for(int i =2 ; i < 21 ; i++){
        System.out.println(i * 5);
        updateProgress(i * 5, 100);
        Thread.sleep(300);
        if(isCancelled()){
            return i;
        }

    }

    return 21;
  }

@Override
public boolean cancel( boolean mayInterruptIfRunning){
    updateMessage("cancelled!");
    return super.cancel(mayInterruptIfRunning);

}

@Override
protected void updateProgress(double workDone, double max){
    updateMessage("Loading..." + " " + workDone + "%");
    super.updateProgress(workDone, max);

}
}
public class LoaderController implements Initializable {

@FXML
private ResourceBundle resources;

@FXML
private URL location;

@FXML
private Label status;

@FXML
private ProgressBar bar;

//@FXML
//private ProgressIndicator indicator;

@Override
public void initialize(URL location, ResourceBundle rb){
DoWork task = new DoWork();

    bar.progressProperty().bind(task.progressProperty());
    //indicator.progressProperty().bind(task.progressProperty());
    status.textProperty().bind(task.messageProperty());

new Thread(task).start(); 

}

public void start(Stage stage) throws Exception {
    stage.initStyle(StageStyle.TRANSPARENT);
    Parent root = 
FXMLLoader.load(getClass().getResource("./splash/sceneOne.fxml"));

    //stage.setTitle("Welcome");
    stage.setScene(new Scene(root, 337, 144));
    stage.show();
}

如何解决此问题？
