CardLayout布局方法说明public void first(Container parent)
翻转到容器的第一张卡片public void last(Container parent)翻转到容器的最后一张卡片public void next(Container parent)翻转到指定容器的下一张卡片public void previous(Container parent)翻转到指定容器的前一张卡片public void show(Container parent)翻转到使用addLayoutConmponent 添加到
此布局的具有指定的name的组件代码：

package Frame;import java.awt.BorderLayout;import java.awt.CardLayout;import java.awt.Color;import java.awt.Insets;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JPanel;public class CardLayoutDemo 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 JButton b_1 = null, b_2 = null, b_3 = null;private JPanel p_1 = null, p_2 = null, p_3 = null;public CardLayoutDemo() {card = new CardLayout(5, 5);pane = new JPanel(card);p = new JPanel();button_1 = new JButton("< 上一步");button_2 = new JButton("下一步  >");b_1 = new JButton("1");b_2 = new JButton("2");b_3 = new JButton("3");b_1.setMargin(new Insets(2, 2, 2, 2));b_2.setMargin(new Insets(2, 2, 2, 2));b_3.setMargin(new Insets(2, 2, 2, 2));p.add(button_1);p.add(b_1);p.add(b_2);p.add(b_3);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_2.add(new JLabel("JPanel_2"));p_3.add(new JLabel("JPanel_3"));pane.add(p_1, "p1");pane.add(p_2, "p2");pane.add(p_3, "p3");button_1.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {card.previous(pane);}});button_2.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {card.next(pane);}});b_1.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stubcard.show(pane, "p1");}});b_2.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stubcard.show(pane, "p2");}});b_3.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stubcard.show(pane, "p3");}});getContentPane().add(pane);getContentPane().add(p, BorderLayout.SOUTH);setSize(300, 200);setVisible(true);}public static void main(String[] args) {new CardLayoutDemo();}}
