1、 边界布局（BorderLayout）

2、流式布局（FlowLayout）

3、网格布局（GridLayout）

4、盒子布局（BoxLaYout）

5、空布局（null）

还有其他两种布局，分别是GridBagLayout（网格包布局）、CardLayout（卡片布局）

注意：JFrame和JDialog默认布局为BorderLayout，JPanel和Applet默认布局为FlowLayout

边界布局示例代码：

import java.awt.BorderLayout;import javax.swing.JButton;import javax.swing.JFrame;public class BorderLayoutExample extends JFrame{ JButton btn1=new JButton("东"); JButton btn2=new JButton("南"); JButton btn3=new JButton("西"); JButton btn4=new JButton("北"); JButton btn5=new JButton("中"); BorderLayoutExample(){ init(); this.setTitle("边界布局"); this.setResizable(true); this.setSize(200, 200); this.setLocationRelativeTo(null); this.setDefaultCloseOperation(EXIT_ON_CLOSE); this.setVisible(true); } void init(){ this.setLayout(new BorderLayout(10,5)); //默认为0，0；水平间距10，垂直间距5 this.add(btn1,BorderLayout.EAST); this.add(btn2,BorderLayout.SOUTH); this.add(btn3,BorderLayout.WEST); this.add(btn4,BorderLayout.NORTH); this.add(btn5,BorderLayout.CENTER); } public static void main(String args[]){ new BorderLayoutExample(); }}

流式布局示例代码：

import java.awt.FlowLayout;import javax.swing.JButton;import javax.swing.JFrame;public class FlowLayoutExample extends JFrame{ JButton btn1=new JButton("one"); JButton btn2=new JButton("two"); JButton btn3=new JButton("three"); JButton btn4=new JButton("four"); JButton btn5=new JButton("five"); FlowLayoutExample(){ init(); this.setTitle("流式布局"); this.setResizable(true); this.setSize(200, 200); this.setLocationRelativeTo(null); this.setDefaultCloseOperation(EXIT_ON_CLOSE); this.setVisible(true); } void init(){ this.setLayout(new FlowLayout(FlowLayout.LEFT,10,5)); //默认为居中;水平间距10，垂直间距5 this.add(btn1); this.add(btn2); this.add(btn3); this.add(btn4); this.add(btn5); } public static void main(String args[]){ new FlowLayoutExample(); }}

网格布局示例代码：

import java.awt.GridLayout;import javax.swing.JButton;import javax.swing.JFrame;public class GridLayoutExample extends JFrame{ JButton btn1=new JButton("one"); JButton btn2=new JButton("two"); JButton btn3=new JButton("three"); JButton btn4=new JButton("four"); JButton btn5=new JButton("five"); GridLayoutExample(){ init(); this.setTitle("表格布局"); this.setResizable(true); this.setSize(300, 200); this.setLocationRelativeTo(null); this.setDefaultCloseOperation(EXIT_ON_CLOSE); this.setVisible(true); } void init(){ this.setLayout(new GridLayout(2,3,10,5)); //默认为1行，n列；2行3列，水平间距10，垂直间距5 this.add(btn1); this.add(btn2); this.add(btn3); this.add(btn4); this.add(btn5); } public static void main(String args[]){ new GridLayoutExample(); }}

运行结果：

盒子布局示例代码：

import javax.swing.Box;import javax.swing.BoxLayout;import javax.swing.JButton;import javax.swing.JFrame;public class BoxLaYoutExample extends JFrame{ JButton btn1=new JButton("one"); JButton btn2=new JButton("two"); JButton btn3=new JButton("three"); JButton btn4=new JButton("four"); JButton btn5=new JButton("five"); BoxLaYoutExample(){ init(); this.setTitle("表格布局"); this.setResizable(true); this.setSize(300, 200); this.setLocationRelativeTo(null); this.setDefaultCloseOperation(EXIT_ON_CLOSE); this.setVisible(true); } void init(){ this.setLayout(new BoxLayout(this.getContentPane(),BoxLayout.X_AXIS)); //可以使用Box容器代替 //Box box = new Box(BoxLayout.Y_AXIS);box.add(btn...);box.add(creat..); this.add(btn1); this.add(btn2); this.getContentPane().add(Box.createHorizontalStrut(10)); //采用x布局时，添加固定宽度组件隔开 //this.getContentPane().add(Box.createVerticalStrut(5)); //采用y布局时，添加固定高度组件隔开 this.add(btn3); this.add(btn4); this.add(btn5); } public static void main(String args[]){ new BoxLaYoutExample(); }}

空布局示例代码：

import javax.swing.JButton;import javax.swing.JFrame;public class NullLayoutExample extends JFrame{ JButton btn1=new JButton("one"); JButton btn2=new JButton("two"); JButton btn3=new JButton("three"); JButton btn4=new JButton("four"); JButton btn5=new JButton("five"); NullLayoutExample(){ init(); this.setTitle("空布局"); this.setResizable(true); this.setSize(300, 300); this.setLocationRelativeTo(null); this.setDefaultCloseOperation(EXIT_ON_CLOSE); this.setVisible(true); } void init(){ this.setLayout(null); btn1.setBounds(10, 0, 100, 50); //x坐标10，y坐标0，组件宽100，高50 btn2.setBounds(20, 50, 100, 50); btn3.setBounds(30, 100, 100, 50); btn4.setBounds(40, 150, 100, 50); btn5.setBounds(50, 200, 100, 50); this.add(btn1); this.add(btn2); this.add(btn3); this.add(btn4); this.add(btn5); } public static void main(String args[]){ new NullLayoutExample(); }}
