java - 如何使用 Java Swing 实现多个视图？

Question

所以我想要带有 2-3 个按钮的介绍视图。每个按钮点击都会导致特定视图。我想知道如何使用 Java Swing 来实现这一点？

听起来像是CardLayout的完美工作。

这也是我的一个小演示：

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

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

public class CardLayoutTutorial {
    JFrame frame = new JFrame("CardLayout demo");
    JPanel panelCont = new JPanel();
    JPanel panelFirst = new JPanel();
    JPanel panelSecond = new JPanel();
    JButton buttonOne = new JButton("Switch to second panel/workspace");
    JButton buttonSecond = new JButton("Switch to first panel/workspace");
    CardLayout cl = new CardLayout();

    public CardLayoutTutorial() {
        panelCont.setLayout(cl);

        panelFirst.add(buttonOne);
        panelSecond.add(buttonSecond);
        panelFirst.setBackground(Color.BLUE);
        panelSecond.setBackground(Color.GREEN);

        panelCont.add(panelFirst, "1");
        panelCont.add(panelSecond, "2");
        cl.show(panelCont, "1");

        buttonOne.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent arg0) {
                cl.show(panelCont, "2");
            }
        });

        buttonSecond.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent arg0) {
                cl.show(panelCont, "1");
            }
        });

        frame.add(panelCont);
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);

    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new CardLayoutTutorial();
            }
        });
    }

}

单击buttonOne视图时将切换到panelSecond，单击buttonSecond视图时将切换到panelFirst
