JAVA Swing 获取单选按钮的值，复选框的值

这是我自己写的一个测试程序，要求在点击“提交”按钮时，在监听事件中获取单选按钮的值，和复选框的值

package helloworld;

import java.awt.*;

import javax.swing.*;
import com.borland.jbcl.layout.XYLayout;
import com.borland.jbcl.layout.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Frame1 extends JFrame {
XYLayout xYLayout1 = new XYLayout();
JLabel jLabel1 = new JLabel();
JRadioButton jRadioButton1 = new JRadioButton();
JRadioButton jRadioButton2 = new JRadioButton();
JButton jButton1 = new JButton();
JLabel jLabel2 = new JLabel();
JCheckBox jCheckBox1 = new JCheckBox();
JCheckBox jCheckBox2 = new JCheckBox();
JCheckBox jCheckBox3 = new JCheckBox();

public Frame1() {
try {
jbInit();
} catch (Exception exception) {
exception.printStackTrace();
}
}

private void jbInit() throws Exception {
getContentPane().setLayout(xYLayout1);
jLabel1.setText("性 别：");
xYLayout1.setWidth(326);
xYLayout1.setHeight(214);
jButton1.setText("提 交");
jButton1.addActionListener(new Frame1_jButton1_actionAdapter(this));
jRadioButton2.setText("女");
jLabel2.setText("爱 好：");
jCheckBox1.setText("唱歌");
jCheckBox2.setText("跳舞");
jCheckBox3.setText("阅读");
this.getContentPane().add(jRadioButton1,
new XYConstraints(127, 60, -1, -1));
this.getContentPane().add(jRadioButton2,
new XYConstraints(216, 60, -1, -1));
this.getContentPane().add(jButton1, new XYConstraints(124, 154, -1, -1));
this.getContentPane().add(jLabel2, new XYConstraints(31, 111, -1, -1));
this.getContentPane().add(jLabel1, new XYConstraints(31, 60, 46, 21));
this.getContentPane().add(jCheckBox1, new XYConstraints(97, 106, -1, -1));
this.getContentPane().add(jCheckBox2,
new XYConstraints(164, 106, -1, -1));
this.getContentPane().add(jCheckBox3,
new XYConstraints(233, 106, -1, -1));
jRadioButton1.setText("男");
}

public void jButton1_actionPerformed(ActionEvent e) {

}
}

class Frame1_jButton1_actionAdapter implements ActionListener {
private Frame1 adaptee;
Frame1_jButton1_actionAdapter(Frame1 adaptee) {
this.adaptee = adaptee;
}

public void actionPerformed(ActionEvent e) {
adaptee.jButton1_actionPerformed(e);
}
}

Answer 1

由于我机子上没有你的布局器XYConstraints，所以我全注释了，你可以运行下面程序，能得到结果

package helloworld;

import java.awt.*;

import javax.swing.*;
//import com.borland.jbcl.layout.XYLayout;
//import com.borland.jbcl.layout.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Frame1 extends JFrame {
//XYLayout xYLayout1 = new XYLayout();
JLabel jLabel1 = new JLabel();
JRadioButton jRadioButton1 = new JRadioButton();
JRadioButton jRadioButton2 = new JRadioButton();
JButton jButton1 = new JButton();
JLabel jLabel2 = new JLabel();
JCheckBox jCheckBox1 = new JCheckBox();
JCheckBox jCheckBox2 = new JCheckBox();
JCheckBox jCheckBox3 = new JCheckBox();
public static void main(String[] args) {
Frame1 frame=new Frame1();
frame.setBounds(100, 100, 200, 300);
frame.setVisible(true);
}
public Frame1() {
try {
jbInit();
} catch (Exception exception) {
exception.printStackTrace();
}
}

private void jbInit() throws Exception {
//getContentPane().setLayout(xYLayout1);
getContentPane().setLayout(new BoxLayout(getContentPane(),BoxLayout.Y_AXIS));
jLabel1.setText("性 别：");
//xYLayout1.setWidth(326);
//xYLayout1.setHeight(214);
jButton1.setText("提 交");
jButton1.addActionListener(new Frame1_jButton1_actionAdapter(this));
jRadioButton2.setText("女");
jLabel2.setText("爱 好：");
jCheckBox1.setText("唱歌");
jCheckBox2.setText("跳舞");
jCheckBox3.setText("阅读");
this.getContentPane().add(jLabel1);//, new XYConstraints(31, 60, 46, 21));
this.getContentPane().add(jRadioButton1);//,new XYConstraints(127, 60, -1, -1));
this.getContentPane().add(jRadioButton2);//,new XYConstraints(216, 60, -1, -1));
this.getContentPane().add(jLabel2);//, new XYConstraints(31, 111, -1, -1));
this.getContentPane().add(jCheckBox1);//, new XYConstraints(97, 106, -1, -1));
this.getContentPane().add(jCheckBox2);//,new XYConstraints(164, 106, -1, -1));
this.getContentPane().add(jCheckBox3);//,new XYConstraints(233, 106, -1, -1));
this.getContentPane().add(jButton1);//, new XYConstraints(124, 154, -1, -1));
jRadioButton1.setText("男");
jRadioButton1.setSelected(true);
ButtonGroup bg=new ButtonGroup();
bg.add(jRadioButton1);
bg.add(jRadioButton2);

}

public void jButton1_actionPerformed(ActionEvent e) {
System.out.println("性别："+(jRadioButton1.isSelected()?jRadioButton1.getText():jRadioButton2.getText()));
if(jCheckBox1.isSelected()){
System.out.println(jCheckBox1.getText());
}
if(jCheckBox2.isSelected()){
System.out.println(jCheckBox2.getText());
}
if(jCheckBox3.isSelected()){
System.out.println(jCheckBox3.getText());
}
}
}

class Frame1_jButton1_actionAdapter implements ActionListener {
private Frame1 adaptee;
Frame1_jButton1_actionAdapter(Frame1 adaptee) {
this.adaptee = adaptee;
}

public void actionPerformed(ActionEvent e) {
adaptee.jButton1_actionPerformed(e);
}
}

Answer 2

String radValue= jRadioButton2.getText(); //单选按钮的值
//得到复选框的值
if(jCheckBox1.isSelected()){//如果复选框为选中
String txtValue=jCheckBox1.getText();
}

Answer 3

首先你应该在你所点击的那个按钮建立按钮监听程序，这是首要的。要获得按钮值和复选框的内容可以这样写在testfeild里面：jtextfeild1.setText(jButton1.g
etaction
commond
)

Answer 4

把复选框放到一个数组中，然后循环判断是否为选中。如果选中，则输出。

Answer 5

每个按钮都有一个boolean值表示是否被选中（用isSelected方法获取），根据这个来判断就行了
