Question

我目前正在为我的决赛写一个扑克游戏。我必须使用组合视图：具有实际代码的类和Scenebuilder。我做了我学到的一切，模特工作得很好。我是新手，所以一定要轻松解决！教授希望我们熟悉Scenebuilder，但他们没有给出太多解释。

正如你所看到的，我使用了一个名为pokerView的类，我在其中加载了每张卡片的图像。一开始我使用一个奇怪的forloop自动生成图像的名称，我打印出来并且网址没问题！

我也使用了scenebuilder。它拥有自己的控制器/视图类，即FXMLpokerController

为了将这两者结合起来，我使用了一个＆＃34; super＆＃34;视图。

有趣的是java不会给我任何错误！

我真的需要一个答案。如果窗口显示为空，我无法显示应用程序。

因此终端在使用printstacktrace

时给出了以下行

    javafx.fxml.LoadException:

    this is the FXMLpokerController
    package poker;

import javafx.fxml.FXML;

    counter++;

/**

}

    this is the superview called viewplus

package poker;

import javafx.scene.Parent;
import java.io.IOException;
import javafx.fxml.FXMLLoader;
import javafx.scene.layout.AnchorPane;

public class ViewPlus extends AnchorPane {
private Game model;

private FXMLpokerController fxmlController;

public ViewPlus(Game model) throws IOException{
    this.model = model;
    view = new PokerView(model);
    FXMLLoader loader = new FXMLLoader();
    loader.setLocation(getClass().getResource("FXMLpoker.fxml"));
    try{
        fxmlView = loader.load();
        fxmlController = loader.getController();
        fxmlController.setModel(model);
        fxmlController.setView(this);
        getChildren().addAll(fxmlView,view);  
    } catch(IOException ex){ex.printStackTrace();}

}

public void configureerKaarten(){
    view.configureerStapel();
}

public void turnHandCards(){
    view.turnHandCards();
}

public void turnThreeTableCards(){
    view.turnThreeTableCards();
}

}

这是View控制器

    package poker;


    public class Controller {

private Game model;
private ViewPlus view;

public Controller(Game model, ViewPlus view){
    this.model=model;
    this.view=view;
    view.configureerKaarten();
    view.turnHandCards();
    if(model.getRound().getSpeler1().getStake() == model.getRound().getSpeler2().getStake()
    && model.getRound().getSpeler2().getStake() == model.getRound().getSpeler3().getStake()
    && model.getRound().getSpeler3().getStake() == model.getRound().getSpeler4().getStake()){
        view.turnThreeTableCards();
    }


}

}

这是我的主要课程

   package poker;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;


public class MAINpoker extends Application {

    Game model = new Game();



    ViewPlus view = new ViewPlus (model);


    Scene scene = new Scene(view);

    stage.setScene(scene);
    stage.show();

    Controller c = new Controller(model, view); 

}

/**

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

Answer 1

你的AnchorPane有fx：id“deal”：

<AnchorPane id="AnchorPane" fx:id="deal" prefHeight="605.0" prefWidth="556.0" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="poker.FXMLpokerController">

在你的控制器类FXMLpokerController中，你将“deal”定义为一个按钮：

@FXML
private Button deal;

FXML注入无法将Button初始化为AnchorPane。将fx：id移动到正确的按钮，并为AnchorPane提供不同的fx：id。

Answer 2

您已在FXML中将您的AnchorPane命名为“deal”，并将您的Button命名为控制器中的“deal”。在初始化期间，映射按名称完成。由于这些对象的类型不同，因此您将获得类异常。

如果按钮真的处理完毕，请将id从AnchorPane移动到FXML中的按钮。基于此：

deal.setOnAction(this::deal);

我认为该按钮应该被称为交易。

更改此行

    <AnchorPane id="AnchorPane" prefHeight="605.0" prefWidth="556.0" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="poker.FXMLpokerController">

和这一行

<Button fx:id="deal" layoutX="249.0" layoutY="495.0" mnemonicParsing="false" text="deal" />

运行javaFX应用程序时出现的空窗口，同时使用图形视图和场景构建器
