我是靠谱客的博主傻傻小伙，最近开发中收集的这篇文章主要介绍swing中几种layout示例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

import javax.swing.Box;
import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.TitledBorder;

public class test extends JFrame {
public test() {
super("Common Layout Managers");
setSize(500, 380);

JPanel desktop = new JPanel();
getContentPane().add(desktop);

JPanel fr1 = new JPanel();
fr1.setBorder(new TitledBorder("FlowLayout"));
fr1.setLayout(new FlowLayout());
fr1.add(new JButton("1"));
fr1.add(new JButton("2"));
fr1.add(new JButton("3"));
fr1.add(new JButton("4"));
desktop.add(fr1, 0);

JPanel fr2 = new JPanel();
fr2.setBorder(new TitledBorder("GridLayout"));
fr2.setLayout(new GridLayout(2, 2));
fr2.add(new JButton("1"));
fr2.add(new JButton("2"));
fr2.add(new JButton("3"));
fr2.add(new JButton("4"));
desktop.add(fr2, 0);

JPanel fr3 = new JPanel();
fr3.setBorder(new TitledBorder("BorderLayout"));
fr3.setLayout(new BorderLayout(1, 5));
fr3.add(new JButton("1"), BorderLayout.NORTH);
fr3.add(new JButton("2"), BorderLayout.EAST);
fr3.add(new JButton("3"), BorderLayout.SOUTH);
fr3.add(new JButton("4"), BorderLayout.WEST);
fr3.add(new JButton("5"),BorderLayout.CENTER);
desktop.add(fr3, 0);

JPanel fr4 = new JPanel();
fr4.setBorder(new TitledBorder("BoxLayout - X"));
fr4.setLayout(new BoxLayout(fr4, BoxLayout.X_AXIS));
fr4.add(new JButton("1"));
fr4.add(Box.createHorizontalStrut(12));
fr4.add(new JButton("2"));
fr4.add(Box.createGlue());
fr4.add(new JButton("3"));
fr4.add(Box.createHorizontalGlue());
fr4.add(new JButton("4"));
desktop.add(fr4, 0);

JPanel fr5 = new JPanel();
fr5.setBorder(new TitledBorder("BoxLayout - Y"));
fr5.setLayout(new BoxLayout(fr5, BoxLayout.Y_AXIS));
fr5.add(new JButton("1"));
fr5.add(Box.createVerticalStrut(10));
fr5.add(new JButton("2"));
fr5.add(Box.createGlue());
fr5.add(new JButton("3"));
fr5.add(Box.createVerticalGlue());
fr5.add(new JButton("4"));
desktop.add(fr5, 0);

WindowListener wndCloser = new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
};
addWindowListener(wndCloser);
setVisible(true);
}

public static void main(String argv[]) {
new test();
}
