现在尝试用GridBagLayout设计图形界面，可是总打不到预期效果。
预期效果：
//姓名：（JTextField）
//性别：（JRadioButton）（JRadioButton）
//QQ：（JTextField）
（括号中是对应的组件。）
代码如下：
import java.awt.Container;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class AddContact extends JFrame{
JTextField JTName=new JTextField();
JTextField JTQQ=new JTextField();
JTextField JTPhone=new JTextField();
JTextField JTEmail=new JTextField();
JTextField JTAddr=new JTextField();
JRadioButton JRBM=new JRadioButton("男");
JRadioButton JRBF=new JRadioButton("女");
JButton JBAdd=new JButton("提交");
public AddContact()
{
JPanel jp=new JPanel();
GridBagLayout gb=new GridBagLayout();
GridBagConstraints c=new GridBagConstraints();
JLabel jl=new JLabel();
jp.setLayout(gb);
c.anchor = GridBagConstraints.NORTHWEST;
c.fill = GridBagConstraints.BOTH;
//set name info.
c.gridx=0;
c.gridy=0;
c.gridwidth=1;
c.gridheight=1;
jl.setText("姓名：");
gb.setConstraints(jl, c);
jp.add(jl);
c.gridx=1;
c.gridy=0;
c.gridwidth=2;
c.gridheight=1;
gb.setConstraints(JTName, c);
jp.add(JTName);
//set sex info.
c.gridx=0;
c.gridy=1;
c.gridwidth=1;
c.gridheight=1;
jl.setText("性别：");
gb.setConstraints(jl, c);
jp.add(jl);
c.gridx=1;
c.gridy=1;
c.gridwidth=1;
c.gridheight=1;
gb.setConstraints(JRBM, c);
jp.add(JRBM);
c.gridx=2;
c.gridy=1;
c.gridwidth=1;
c.gridheight=1;
gb.setConstraints(JRBF, c);
jp.add(JRBF);
ButtonGroup bg=new ButtonGroup();
bg.add(JRBM);
bg.add(JRBF);
//set QQ info.
c.gridx=0;
c.gridy=2;
c.gridwidth=1;
c.gridheight=1;
jl.setText("QQ：");
gb.setConstraints(jl, c);
jp.add(jl);
c.gridx=1;
c.gridy=2;
c.gridwidth=2;
c.gridheight=1;
gb.setConstraints(JTQQ, c);
jp.add(JTQQ);
this.add(jp);
this.setVisible(true);
this.pack();
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String[] args)
{
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
new AddContact();}});
}
}
就是这个我弄一晚上了，有劳各位多多纠正啊。

在你的基础上作出修改，代码如下：
- Java code
//import java.awt.Container;import java.awt.GridBagConstraints;import java.awt.GridBagLayout;//import java.awt.event.ActionEvent;//import java.awt.event.ActionListener;import javax.swing.*;public class GBCTest extends JFrame{ public GBCTest() { JTextField JTName=new JTextField(); JTextField JTQQ=new JTextField(); //JTextField JTPhone=new JTextField(); //JTextField JTEmail=new JTextField(); //JTextField JTAddr=new JTextField(); JRadioButton JRBM=new JRadioButton("男"); JRadioButton JRBF=new JRadioButton("女"); //JButton JBAdd=new JButton("提交"); JPanel jp=new JPanel(); GridBagLayout gb=new GridBagLayout(); GridBagConstraints c=new GridBagConstraints(); JLabel jl= new JLabel(); JLabel j2 = new JLabel(); JLabel j3 = new JLabel(); jp.setLayout(gb); c.anchor = GridBagConstraints.NORTHWEST; c.fill = GridBagConstraints.BOTH;//set name info. c.gridx=0; c.gridy=0; c.gridwidth=1; c.gridheight=1; jl.setText("姓名："); gb.setConstraints(jl, c); jp.add(jl); c.gridx=1; c.gridy=0; c.gridwidth=2; c.gridheight=1; gb.setConstraints(JTName, c); jp.add(JTName);//set sex info. c.gridx=0; c.gridy=1; c.gridwidth=1; c.gridheight=1; j2.setText("性别："); gb.setConstraints(j2, c); jp.add(j2); c.gridx=1; c.gridy=1; c.gridwidth=1; c.gridheight=1; gb.setConstraints(JRBM, c); jp.add(JRBM); c.gridx=2; c.gridy=1; c.gridwidth=1; c.gridheight=1; gb.setConstraints(JRBF, c); jp.add(JRBF); ButtonGroup bg=new ButtonGroup(); bg.add(JRBM); bg.add(JRBF);//set QQ info. c.gridx=0; c.gridy=2; c.gridwidth=1; c.gridheight=1; j3.setText("QQ："); gb.setConstraints(j3, c); jp.add(j3); c.gridx=1; c.gridy=2; c.gridwidth=2; c.gridheight=1; gb.setConstraints(JTQQ, c); jp.add(JTQQ); this.add(jp); this.setVisible(true); this.pack(); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { new GBCTest();}}); }}
