如何使用ActionListener检测是否选择了一个JRadioButton？
[英]How do I detect if a single JRadioButton is selected or not using ActionListener?
问题描述
First, Here is the code in its entirety. 
首先，这是完整的代码。 It was mostly auto generated by netbeans as i am terrible at creating GUIs: 它主要由netbeans自动生成，因为我在创建GUI时很糟糕：

if(tempBtn.isEnabled()) {
jFormattedTextField1.enableInputMethods(false);
jFormattedTextField2.enableInputMethods(false);
System.out.println("Date box disabled");
In an attempt to check if the button is ticked or not. 试图检查按钮是否被勾选。 However, each time I tick or untick the button, it prints "Date box disabled!", in both methods, despite there being a check if the button is enabled. 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！”。 Here is a screengrab of the GUI: Picture of the GUI 这是GUI的屏幕截图：GUI的图片
My end goal is for the Start date and end date text fields to be disabled when the Search by age button is ticked, and for the Age text field to be disabled when the radio button is unticked. 我的最终目标是，当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。 I'm not sure if the method I'm checking the buttons status is incorrect, or if there is something else wrong with my code :/ 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：/
Any help would be greatly appreciated! 任何帮助将不胜感激！

Ideally to enabling/disabling certain buttons based on a button's state, you should not use a JRadioButton instance, we need to have JCheckBox in that place to cater the needs. 理想情况下，根据按钮的状态启用/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。
I modified the code with JCheckBox and enabling/disabling buttons based on check box state with help of ItemListener and ItemEvent. 我使用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 has one useful method getStateChange() which will returns you about whether checkbox is Selected or Deselected. 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。 Based on that you can do your required operations. 基于此，您可以执行所需的操作。
To enable/disable a particular component user setEnabled(boolean value) method. 若要启用/禁用特定组件，请使用setEnabled（boolean value）方法。 Pass value as true if you want to enable, false otherwise. 如果要启用，则将值传递为true，否则传递false。
Here is the short code jcheckbox listener code : 这是短代码jcheckbox侦听器代码：
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);
}
});
And below is the entire working code. 下面是整个工作代码。

Still if you want to do with JRadioButton, you can use itemListener as I have used above. 仍然，如果您想使用JRadioButton，您可以像我上面使用的那样使用itemListener。
