Question

我正在努力制作正在进行的Tic Tac Toe游戏。我在将图像加载到JButton时遇到问题。我刚刚编写了一个按钮。我做了一个res文件，就像res / image / Cross.png和Circle.png。它们位于构建路径中。但即使单击按钮，也不会显示图像我唯一的课程

    package com.arjav.tictactoe ;

    import java.awt.GridLayout;
    import java.awt.Image;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;

    import javax.swing.ImageIcon;
    import javax.swing.JButton;
    import javax.swing.JFrame;
    public class TTT implements ActionListener{
    JFrame frame ;

    int turn = 0 ;
    ImageIcon cross = new ImageIcon("Cross.png");
    ImageIcon circle = new ImageIcon("Circle.png");

    public JButton x1y1 = new JButton("Click me");
    public JButton x2y1 = new JButton("Click me");
    public JButton x3y1 = new JButton("Click me");
    public JButton x1y2 = new JButton("Click me");
    public JButton x2y2 = new JButton("Click me");
    public JButton x3y2 = new JButton("Click me");
    public JButton x1y3 = new JButton("Click me");
    public JButton x2y3 = new JButton("Click me");
    public JButton x3y3 = new JButton("Click me");

    public TTT(){
        frame = new JFrame();
        frame.setTitle("Let's Play Tic Tac Toe ?? YES!!");
        frame.setSize(300 , 300);
        frame.setResizable(false);
        frame.setVisible(true);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        init();
    }
    public void init(){
        GridLayout layout = new GridLayout(3 , 3);
        frame.setLayout(layout);
        frame.add(x1y1);
        frame.add(x2y1);
        frame.add(x3y1);
        frame.add(x1y2);
        frame.add(x2y2);
        frame.add(x3y2);
        frame.add(x1y3);
        frame.add(x2y3);
        frame.add(x3y3);
        x1y1.addActionListener(this);
        x2y1.addActionListener(this);
        x3y1.addActionListener(this);
        x1y2.addActionListener(this);
        x2y2.addActionListener(this);
        x3y2.addActionListener(this);
        x1y3.addActionListener(this);
        x2y3.addActionListener(this);
        x3y3.addActionListener(this);
    }

    public void actionPerformed(ActionEvent e) {
        if(e.getSource() == x1y1){

            if(turn == 0) {x1y1.setIcon(circle);
            turn++ ;
            System.out.println(turn);
            }

        }

    }

    public static void main(String[] args)
    {
       TTT main = new TTT();
    }
}

使用 ImageIcon circle = new ImageIcon(getClass().getResource("Circle.png")); 代替 ImageIcon circle = new ImageIcon("Circle.png");。如果您的图标图像不在默认包中，则必须使用"/res/image/Circle.png"

之类的图标路径

无法使用ImageIcons将图像绘制到JButton上
