1、 边界布局BorderLayout2、流式布局FlowLayout3、网格布局GridLayout4、盒子布局BoxLaYout5、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BorderLayoutJPanel和Applet默认布局为FlowLayout。
2、边界布局BorderLayout
实例如下
public class BorderLayoutExample extends JFrame {JButton btn1new JButton(东);JButton btn2new JButton(南);JButton btn3new JButton(西);JButton btn4new JButton(北);JButton btn5new JButton(中);BorderLayoutExample(){init();this.setTitle(边界布局);this.setResizable(true);this.setSize(300, 300);this.setLocationRelativeTo(null);this.setDefaultCloseOperation(EXIT_ON_CLOSE);this.setVisible(true);}void init(){this.setLayout(new BorderLayout(10,5)); //默认为00水平间距10垂直间距5this.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();}
}运行结果如下
3、流式布局FlowLayout
实例如下
public class FlowLayoutExample extends JFrame {JButton btn1new JButton(one);JButton btn2new JButton(two);JButton btn3new JButton(three);JButton btn4new JButton(four);JButton btn5new JButton(five);FlowLayoutExample(){init();this.setTitle(流式布局);this.setResizable(true);this.setSize(300, 300);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5this.add(btn1);this.add(btn2);this.add(btn3);this.add(btn4);this.add(btn5);}public static void main(String args[]){new FlowLayoutExample();}
}运行结果如下
4、网格布局GridLayout
实例如下
public class GridLayoutExample extends JFrame {JButton btn1new JButton(one);JButton btn2new JButton(two);JButton btn3new JButton(three);JButton btn4new JButton(four);JButton btn5new JButton(five);GridLayoutExample(){init();this.setTitle(表格布局);this.setResizable(true);this.setSize(300, 300);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5this.add(btn1);this.add(btn2);this.add(btn3);this.add(btn4);this.add(btn5);}public static void main(String args[]){new GridLayoutExample();}
}运行结果如下
5、盒子布局BoxLaYout
实例如下
public class BoxLayoutExample extends JFrame {JButton btn1new JButton(one);JButton btn2new JButton(two);JButton btn3new JButton(three);JButton btn4new JButton(four);JButton btn5new JButton(five);BoxLayoutExample(){init();this.setTitle(表格布局);this.setResizable(true);this.setSize(300, 300);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();}
}运行结果如下
6、空布局null
实例如下
public class NullLayoutExample extends JFrame {JButton btn1new JButton(one);JButton btn2new JButton(two);JButton btn3new JButton(three);JButton btn4new JButton(four);JButton btn5new 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10y坐标0组件宽100高50btn2.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();}
}运行结果如下 注感兴趣的小伙伴可以试试可以直接运行
