import java.awt.CardLayout;
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.Panel;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class Test {
private JFrame frame;
private JLabel l1;
private JLabel l2;
private JLabel l3;
private JButton b1;
private JButton b2;
private CardLayout c;
private Panel p1;
private Panel p2;

public Test(){
frame=new JFrame("Test");
c=new CardLayout();
l1=new JLabel("Label1");
l2=new JLabel("Label2");
l3=new JLabel("Label3");

b1=new JButton("<-");
b2=new JButton("->");

p1=new Panel();
p2=new Panel();

frame.setLayout(new FlowLayout(FlowLayout.CENTER,0,0));
p1.setLayout(c);
l1.setBackground(Color.red);
l2.setBackground(Color.green);
l3.setBackground(Color.blue);
p1.add("a",l1);//用“1”，“one”皆可
p1.add("b",l2);
p1.add("c",l3);
frame.add(p1);
p2.setLayout(new FlowLayout(FlowLayout.CENTER,0,50));
p2.add(b1);
p2.add(b2);
frame.add(p2);

frame.setVisible(true);
frame.setSize(250,150);
frame.setLocation(200,200);

b1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
if(e.getSource()==b1){
c.previous(p1);//上一个
}
}

});
b2.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
if(e.getSource()==b2)c.next(p1);
}

});

}

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

追问

你能不能在每一个卡片里加上按键，文本框，文本区，一类的东西，每个卡片的东西不一样，谢谢了！

追答

不是有个label显示的不一样了么..

追问

你的label上只是颜色，我需要的是每一页上的东西不一样，比如：第一页有个按键和文本框，第二页上有文本区，第三个上有个两个复选框；就这些吧！！辛苦你了！！谢谢了！！！

public class Card extends JFrame {
private JPanel pane = null;
private JPanel p = null;
private CardLayout card = null;
private JButton button_1 = null;
private JButton button_2 = null;
private JPanel p_1 = null, p_2 = null, p_3 = null;

public Card() {
super("CardLayout Test");
card = new CardLayout(5, 5);
pane = new JPanel(card);
p = new JPanel(); // 构造放按钮的JPanel
button_1 = new JButton("");

p.add(button_1);
p.add(button_2);
p_1 = new JPanel();
p_2 = new JPanel();
p_3 = new JPanel();
p_1.setBackground(Color.RED);
p_2.setBackground(Color.BLUE);
p_3.setBackground(Color.GREEN);
p_1.add(new JLabel("JPanel_1"));
p_1.add(new JButton("haha"));
p_2.add(new JLabel("JPanel_2"));
p_2.add(new JTextArea(10,10));
p_3.add(new JLabel("JPanel_3"));
p_3.add(new JCheckBox());
p_3.add(new JCheckBox());
pane.add(p_1, "p1");
pane.add(p_2, "p2");
pane.add(p_3, "p3");
button_1.addActionListener(new ActionListener(){ // 上一步的按钮动作
public void actionPerformed(ActionEvent e) {
card.previous(pane);
}
});
button_2.addActionListener(new ActionListener(){ // 下一步的按钮动作
public void actionPerformed(ActionEvent e) {

this.getContentPane().add(pane);
this.getContentPane().add(p, BorderLayout.SOUTH);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setSize(400, 200);
this.setVisible(true);
}
public static void main(String[] args) {
new Card();
