用swing组件，设计实现用户注册界面，给用户注册界面添加事件处理，单击注册，获取用户信息显示，单
今天刚好有人问过类似的问题.我写了一个. 你参考下.效果图细节等, 你可以自己修改import javax.swing.*;import java.awt.*;import java.awt.event.*;import javax.swing.*;public class RegFrame extends JFrame { private JTextField name; private JTextField psw; public RegFrame() { JPanel panel = new JPanel(); getContentPane().add(panel, BorderLayout.CENTER); panel.setLayout(new GridLayout(6, 1, 5, 2)); JPanel panel_1 = new JPanel(); panel.add(panel_1); JLabel lblNewLabel = new JLabel("用户名"); panel_1.add(lblNewLabel); name = new JTextField(); panel_1.add(name); name.setColumns(10); JPanel panel_2 = new JPanel(); panel.add(panel_2); JLabel label = new JLabel("密 码"); panel_2.add(label); psw = new JTextField(); panel_2.add(psw); psw.setColumns(10); JPanel panel_3 = new JPanel(); panel.add(panel_3); final JRadioButton rb1 = new JRadioButton("男"); panel_3.add(rb1); JRadioButton rb2 = new JRadioButton("女"); panel_3.add(rb2); ButtonGroup bg = new ButtonGroup(); bg.add(rb1); rb1.setSelected(true); bg.add(rb2); JPanel panel_4 = new JPanel(); panel.add(panel_4); JLabel ageLabel = new JLabel("出生年份"); panel_4.add(ageLabel); String[] nians = { "1989", "1990", "1991", "1992" }; final JComboBox comboBox = new JComboBox(nians); panel_4.add(comboBox); JPanel panel_5 = new JPanel(); panel.add(panel_5); final JCheckBox cb1 = new JCheckBox("蓝球"); panel_5.add(cb1); final JCheckBox cb2 = new JCheckBox("足球"); panel_5.add(cb2); final JCheckBox cb3 = new JCheckBox("游泳"); panel_5.add(cb3); JPanel panel_6 = new JPanel(); panel.add(panel_6); JButton jbreg = new JButton("注册"); panel_6.add(jbreg); JButton jbrest = new JButton("取消"); panel_6.add(jbrest); JPanel panel_7 = new JPanel(); getContentPane().add(panel_7, BorderLayout.SOUTH); JLabel reginfo = new JLabel(" "); panel_7.add(reginfo); setSize(380,300);//窗口大小 setLocationRelativeTo(null);//居中 setDefaultCloseOperation(EXIT_ON_CLOSE);//退出 setTitle("注册窗口");//标题 jbreg.addActionListener(new ActionListener() {//注册按钮的事件 @Override public void actionPerformed(ActionEvent e) { StringBuilder sb = new StringBuilder(); String id = name.getText(); sb.append("用户名:" + id); String pas = psw.getText(); sb.append(" 密码:" + pas); if (rb1.isSelected()) { sb.append(" 性别:" + "男"); } else { sb.append(" 性别:" + "女"); } sb.append(" 出生年份:" + comboBox.getSelectedItem().toString()); sb.append(" 爱好:"); if (cb1.isSelected()) { sb.append(cb1.getText()); } if (cb2.isSelected()) { sb.append(cb2.getText()); } if (cb3.isSelected()) { sb.append(cb3.getText()); } reginfo.setText(sb.toString()); } }); jbrest.addActionListener(new ActionListener() {//重置按钮的事件 @Override public void actionPerformed(ActionEvent e) { name.setText(""); psw.setText(""); rb1.setSelected(true); comboBox.setSelectedIndex(0); cb1.setSelected(false); cb2.setSelected(false); cb3.setSelected(false); reginfo.setText(" "); } }); } public static void main(String[] args) { new RegFrame().setVisible(true); }}
