我尝试使用：

// TODO add your handling code here:
javax.swing.JRadioButton tempBtn = (javax.swing.JRadioButton)evt.getSource();
if(tempBtn.isEnabled()) {
jFormattedTextField1.enableInputMethods(false);
jFormattedTextField2.enableInputMethods(false);
System.out.println("Date box disabled");
尝试检查按钮是否被勾选。 但是，每次我勾选或取消勾选该按钮时，尽管都会检查按钮是否已启用，但在两种方法中，它都会打印“日期框已禁用！”。 这是GUI的屏幕截图： Picture of the GUI
我的最终目标是，勾选“按年龄搜索”按钮时，“开始日期”和“结束日期”文本字段将被禁用，而当未选中“单选按钮”时，“年龄”文本字段将被禁用。 我不确定我检查按钮状态的方法是否不正确，或者我的代码是否存在其他问题：/
任何帮助将不胜感激！
答案 0 :(得分：0)
理想情况下，基于按钮状态启用/禁用某些按钮，您不应使用JRadioButton实例，我们需要在该位置放置JCheckBox来满足需要。
我用JCheckBox修改了代码，并在ItemListener和ItemEvent的帮助下基于复选框状态启用/禁用了按钮。 ItemEvent有一个有用的方法getStateChange（），它将向您返回有关复选框处于选中状态还是取消选中状态的信息。基于此，您可以执行所需的操作。
启用/禁用特定组件的用户setEnabled（boolean value）方法。 如果要启用，则将值传递为true，否则为false。
这是jcheckbox侦听器的简短代码：
checkBox.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
boolean flag = e.getStateChange() == ItemEvent.SELECTED;
jFormattedTextField1.setEnabled(!flag);// Here if check box is selected then flag value will be true and this text field would be disabled
jFormattedTextField2.setEnabled(!flag);
jFormattedTextField3.setEnabled(flag);
}
});
下面是整个工作代码。

如果您想使用JRadioButton，也可以像上面一样使用itemListener。
