cardlayout类具有可以满足您的要求的有用的API。使用类似的方法next(), first(), last()可能会有所帮助。我准备了一个简单的演示，该演示在父面板和/或框架中更改面板。看一看：
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class PanelChanger implements ActionListener
{
JPanel panels;
public void init(Container pane)
{
JButton switcher = new JButton("Switch Active Panel!");
switcher.addActionListener(this);
JPanel login = new JPanel();
login.setBackground(Color.CYAN);
login.add(new JLabel("Welcome to login panel."));
JPanel another = new JPanel();
another.setBackground(Color.GREEN);
another.add(new JLabel("Yeah, this is another panel."));
panels = new JPanel(new cardlayout());
panels.add(login);
panels.add(another);
pane.add(switcher, BorderLayout.PAGE_START);
pane.add(panels, BorderLayout.CENTER);
}
public void actionPerformed(ActionEvent evt)
{
cardlayout layout = (cardlayout)(panels.getLayout());
layout.next(panels);
}
public static void main(String[] args)
{
JFrame frame = new JFrame("cardlayoutDemo");
PanelChanger changer = new PanelChanger();
changer.init(frame.getContentPane());
frame.pack();
frame.setVisible(true);
}
}
