您可以使用BoxLayout：
import java.awt.*;import java.awt.event.*;import javax.swing.*;import javax.swing.border.*;public class BoxExample extends Jframe{ public BoxExample() { Box box = Box.createHorizontalBox(); box.setBorder( new EmptyBorder(5, 5, 5, 5) ); Dimension size = new Dimension(100, 25); box.add( createButton("Button1", size) ); box.add( createStrut() ); box.add( createButton("Button2", size) ); box.add( createStrut() ); box.add( createButton("Button3", size) ); box.add( createStrut() ); box.add( createButton("Button4", size) ); add( box ); } private JButton createButton(String text, Dimension size) { JButton button = new JButton(text); button.setPreferredSize( size ); button.setMinimumSize( size ); button.setMaximumSize( size ); return button; } private Component createStrut() { JComponent component = (JComponent)Box.createHorizontalStrut(5); component.setMinimumSize(new Dimension(0, 0)); component.setMaximumSize(new Dimension(Short.MAX_VALUE, Short.MAX_VALUE)); return component; } public static void main(String[] args) { BoxExample frame = new BoxExample(); frame.setDefaultCloseOperation( EXIT_ON_CLOSE ); frame.pack(); frame.setLocationRelativeTo( null ); frame.setVisible(true); }}
