在这里尝试这个代码示例,这将适用于您的情况：

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class LabelOverLabel

{

public static final String HTML =

"" +

"

"body, html { padding: 0px; margin: 0px; }" +

"" +

"

" +

"

" width=320 height=240>" +

"";

private static final String PLAYERONE =

"" +

"

"body, html { padding: 0px; margin: 0px; }" +

"" +

"

" +

"

" width=160 height=120>" +

"";

private static final String PLAYERTWO =

"" +

"

"body, html { padding: 0px; margin: 0px; }" +

"" +

"

" +

"

" width=160 height=120>" +

"";

private JLabel playerOneLabel;

private JLabel playerTwoLabel;

private void createAndDisplayGUI()

{

JFrame frame = new JFrame("JLabel Over JLabel");

frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

final JLabel bottomLabel = new JLabel(HTML);

bottomLabel.setLayout(new FlowLayout(FlowLayout.LEFT, 2, 2));

playerOneLabel = new JLabel(PLAYERONE);

bottomLabel.add(playerOneLabel);

JButton insertPlayer = new JButton("INSERT");

insertPlayer.addActionListener(new ActionListener()

{

public void actionPerformed(ActionEvent ae)

{

playerTwoLabel = new JLabel(PLAYERTWO);

bottomLabel.add(playerTwoLabel);

bottomLabel.revalidate();

bottomLabel.repaint();

}

});

frame.getContentPane().add(bottomLabel, BorderLayout.CENTER);

frame.getContentPane().add(insertPlayer, BorderLayout.PAGE_END);

frame.pack();

frame.setLocationByPlatform(true);

frame.setVisible(true);

}

public static void main(String... args)

{

SwingUtilities.invokeLater(new Runnable()

{

public void run()

{

new LabelOverLabel().createAndDisplayGUI();

}

});

}

}

这是相同的输出：

另一种实现此目的的方法是：

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class LabelOverLabel

{

private JLabel playerOneLabel;

private JLabel playerTwoLabel;

private Icon[] icons = {UIManager.getIcon("OptionPane.informationIcon"),

UIManager.getIcon("OptionPane.errorIcon"),

UIManager.getIcon("OptionPane.warningIcon")};

private void createAndDisplayGUI()

{

JFrame frame = new JFrame("JLabel Over JLabel");

frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

final JLabel bottomLabel = new JLabel("I am a JLabel");

bottomLabel.setBorder(BorderFactory.createLineBorder(Color.BLUE.darker(), 5));

//bottomLabel.setIcon(icons[0]);

bottomLabel.setLayout(new FlowLayout(FlowLayout.LEFT, 2, 2));

playerOneLabel = new JLabel();

playerOneLabel.setIcon(icons[1]);

bottomLabel.add(playerOneLabel);

JLabel secondLabel = new JLabel("1");

bottomLabel.add(secondLabel);

JButton insertPlayer = new JButton("INSERT");

insertPlayer.addActionListener(new ActionListener()

{

public void actionPerformed(ActionEvent ae)

{

playerTwoLabel = new JLabel();

playerTwoLabel.setIcon(icons[2]);

bottomLabel.add(playerTwoLabel);

bottomLabel.revalidate();

bottomLabel.repaint();

}

});

frame.getContentPane().add(bottomLabel, BorderLayout.CENTER);

frame.getContentPane().add(insertPlayer, BorderLayout.PAGE_END);

frame.pack();

frame.setLocationByPlatform(true);

frame.setVisible(true);

}

public static void main(String... args)

{

SwingUtilities.invokeLater(new Runnable()

{

public void run()

{

new LabelOverLabel().createAndDisplayGUI();

}

});

}

}

输出是：
