对于我正在制作的游戏，我希望玩家从菜单屏幕 (Panel05) 开始，然后单击按钮开始实际游戏 (Panel00)。而且，在玩游戏时，如果他们赢了或输了，当他们点击另一个按钮时，他们要么返回菜单，要么进入另一个级别。现在，面板都是独立的程序，有自己的驱动程序，我不确定如何让一个面板在另一个面板中工作，如果可能的话。我将不胜感激任何和所有的建议、答案或批评。下面是菜单面板
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.image.BufferedImage;
public class Panel05 extends JPanel
{
private BufferedImage myImage;
private Graphics myBuffer;
public JButton button1;
public Panel05()
{
myImage = new BufferedImage(1000, 1000, BufferedImage.TYPE_INT_RGB);
myBuffer = myImage.getGraphics();
setLayout(null);
button1 = new JButton();
button1.setSize(100, 100);
button1.setLocation(500,500);
button1.setForeground(Color.WHITE);
button1.setFont(new Font("Serif", Font.BOLD, 30));
button1.setText("Start");
button1.addActionListener(new B1Listener());
button1.setBorder(null);
button1.setOpaque(false);
button1.setContentAreaFilled(false);
button1.setBorderPainted(false);
add(button1);
setFocusable(true);
}
public void paintComponent(Graphics g)
{
ImageIcon Nintendo = new ImageIcon("trumpL.png");
g.drawImage(Nintendo.getImage(), 0, 0, 1000, 1000, null);
}
private class B1Listener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
}
}
}
这是游戏实际第一关的面板。

最佳答案
建议:
- 首先，也是最重要的，使用 CardLayout 交换 JPanel。您将需要另一个 JPanel，一个使用 CardLayout 的 JPanel，您将使用适当的字符串 constant 将上面的两个 JPanel 添加到第一个 JPanel，然后您可以随意交换 JPanel。 CardLayout Tutorial会告诉你怎么做。我已经发布了一些可以在 these links 中找到的代码. Here's a nice one .
- 代码中的其他严重问题——首先，永远不要在 paintComponent 方法中读取图像或任何其他文件。这种方法主要决定了您的 GUI 的感知响应能力，您永远不想减慢它的速度。而且，为什么要这样做？为什么不读入图像一次，将其存储在一个变量中，然后就完成了？
- 还要在覆盖中调用
super.paintComponent(...)方法，否则您可能无法清除 GUI 中的脏像素。 - 还要避免像瘟疫一样使用空布局。虽然空布局和
setBounds()对于 Swing 新手来说似乎是创建复杂 GUI 的最简单和最好的方法，但您创建的 Swing GUI 越多，使用它们时遇到的困难就越严重。当 GUI 调整大小时，它们不会调整组件的大小，它们是增强或维护的皇家女巫，当放置在滚动 Pane 中时它们会完全失败，当在所有平台或与原始屏幕分辨率不同的屏幕分辨率上查看时，它们看起来很糟糕.
