关于JFrame 布局的问题

问，这样的界面怎么布局？按照我的理解是 网式布局。实了好几次都没成功。能否帮忙解决一下。

Answer 1

用布局管理器 真是复杂，
public class TestFrame {

public static void main(String[] args) {
MFrame frame = new MFrame();

}

}

class MFrame extends JFrame{
public MFrame(){
JLabel jl = new JLabel("欢迎注册",SwingUtilities.CENTER);
Font font = new Font("宋体",Font.BOLD,24);
jl.setFont(font);
jl.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));
this.add(jl,BorderLayout.NORTH);

font = new Font("宋体",Font.PLAIN,12);

JLabel jl_name = new JLabel("用户名：",SwingUtilities.RIGHT);
jl_name.setFont(font);

JLabel jl_id = new JLabel("身份证号：",SwingUtilities.RIGHT);
jl_id.setFont(font);

JLabel jl_pass1 = new JLabel("密码：",SwingUtilities.RIGHT);
jl_pass1.setFont(font);

JLabel jl_pass2 = new JLabel("确认密码：",SwingUtilities.RIGHT);
jl_pass2.setFont(font);

JLabel jl_count = new JLabel("存储金额：",SwingUtilities.RIGHT);
jl_count.setFont(font);

JPanel jp_center_left = new JPanel();
jp_center_left.setLayout(new GridLayout(5,1));
jp_center_left.add(jl_name);
jp_center_left.add(jl_id);
jp_center_left.add(jl_pass1);
jp_center_left.add(jl_pass2);
jp_center_left.add(jl_count);

JTextField jt_name = new JTextField();
JTextField jt_id = new JTextField(" ");
JPasswordField jt_pass1 = new JPasswordField();
JPasswordField jt_pass2 = new JPasswordField();
jt_pass1.setEchoChar('*');
jt_pass2.setEchoChar('*');
JTextField jt_count = new JTextField();

JPanel jp_center_right = new JPanel();
jp_center_right.setLayout(new GridLayout(5,1));
jp_center_right.add(jt_name);
jp_center_right.add(jt_id);
jp_center_right.add(jt_pass1);
jp_center_right.add(jt_pass2);
jp_center_right.add(jt_count);

JPanel jp_center = new JPanel();
jp_center.setLayout(new GridLayout(1,2));
jp_center.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 60));
jp_center.add(jp_center_left);
jp_center.add(jp_center_right);

JButton jb1 = new JButton("确认");
JButton jb2 = new JButton("返回");

JPanel jp_south = new JPanel();
jp_south.add(jb1);
jp_south.add(jb2);
jp_south.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));

this.add(jp_center);
this.add(jp_south,BorderLayout.SOUTH);

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
this.setSize(370, 280);
this.setResizable(false);
this.setLocationRelativeTo(null);
}
}

你直接下载一个netbeans 上面有很多控件，直接拖动就可以！或者你如果是eclipse 3.4以上的版本，下载可视化的java Swing 图形界面插件，就可以可视化设置，拖控件！
