如何调用创建按钮的方法，但是在调用该方法时我可以更改单击按钮时发生的情况

Question

我知道这是一个令人困惑的标题，但我会尽力在这里更好地解释它。我目前正在尝试创建一个游戏，并希望拥有在整个游戏中执行不同操作的按钮。我认为有这样的方法就足够简单了：

public void ButtonCreation(String bText, int x, int y, int Width, int Height, int fontSize){
    this.Bol = false;

    this.btex = bText;

    this.bSize = fontSize;

    this.by = y;
    this.bx = x;

    this.bw = Width;
    this.bh = Height;





        JToggleButton Button = new JToggleButton(bText);
        Button.setBackground(new Color(75, 67, 67));
        Button.setForeground(Color.BLACK);
        Button.setFont(new Font("Arial", Font.BOLD,fontSize));
        Button.setBorder(BorderFactory.createLineBorder(Color.BLACK));
        Button.setFocusPainted(false);

        Button.setSize(Width,Height);
        Button.setLocation(x,y);



        frame.add(Button);

                    intro.Button.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                if(intro.Button.getModel().isPressed()){
                    intro.Bol = true;  //What Im trying to change when I call the method (as in add more code into here)
                   

                }

                if(!intro.Button.getModel().isPressed()){
                    intro.Bol = false;
                }

            }
        });

}

我在不同的类 MainClass 中调用该方法。这是我定期调用它：

intro.ButtonCreation("开始游戏", 550,490,200,50,22);

如果有人对如何访问代码的执行部分并在调用方法时编辑/添加它有想法，我们将不胜感激。

我尝试过在主类中执行操作，然后在创建按钮后对其进行更改，但这不起作用。预先感谢！

将

ActionListener

的实例传递给工厂方法。这支持像依赖注入、单一职责原则这样的概念，它将降低内聚性（即解耦你的代码），使其更容易推理、调试和维护......

public JButton createButton(String bText, int fontSize, ActionListener listener) {
    // This seems to be irrelevant - why would you otherwise
    // need this information and I would consider it a side
    // effect see "single responsibility" for more details
    //this.Bol = false;
    //this.btex = bText;
    //this.bSize = fontSize;
    //this.by = y;
    //this.bx = x;
    //this.bw = Width;
    //this.bh = Height;

    JToggleButton button = new JToggleButton(bText);
    button.setBackground(new Color(75, 67, 67));
    button.setForeground(Color.BLACK);
    button.setFont(new Font("Arial", Font.BOLD, fontSize));
    button.setBorder(BorderFactory.createLineBorder(Color.BLACK));
    button.setFocusPainted(false);

    // Try not to manually size or position your controls
    // Make use of appropriate layout managers instead
    
    button.addActionListener(listener);
    
    return button

    // I'd consider this a side effect and a code smell.
    // Why should creating the button also add it?
    // frame.add(Button);

    // No idea what this or why it's here, but immediately, it's
    // raising alarm bells.
    //intro.Button.addActionListener(new ActionListener() {
    //
    //    @Override
    //    public void actionPerformed(ActionEvent e) {
    //        if (intro.Button.getModel().isPressed()) {
    //            intro.Bol = true;  //What Im trying to change when I call the method (as in add more code into here)
    //
    //        }
    //
    //        if (!intro.Button.getModel().isPressed()) {
    //            intro.Bol = false;
    //        }
    //
    //    }
    //});
}

您可能还想探索 构建器模式

这可以让你做类似的事情......

JButton btn = new ButtonBuilder(actionListener)
        .withText(bText)
        .withFontSize(fontSize)
        // .. other properties
        .build();
