问题描述

我正在用java创建一个项目。我的程序有80个JRadioButtons ....我需要获取它们的文本值..现在这些radiobuttons被添加到ButtonGroup（每个都有4个单选按钮）...

I am creating a project in java. My Program has 80 JRadioButtons .... I need the get the text value of them.. Now these radiobuttons are added to ButtonGroup(each has 4 radio buttons)...

我知道如何通过以下代码从单选按钮获取文本值

I know how to get the text value from the radio button by this following code

radiobutton1.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                String q1=e.getActionCommand();
                JOptionPane.showMessageDialog(null, q1);
            }
        });

现在有什么简单的方法吗？因为我将不得不在上面的代码执行80次（如果我使用上面的方法使用上述方法，则为80个radiobuttons

Now is there any easy way to do this? because i will have to do this above code for 80 times(for eighty radiobuttons if i use the above use the above method

附加信息 - 我有20个ButtonGroups，每个4个单选按钮。所以（80个单选按钮）。

Additional Info- I have Total 20 ButtonGroups each with 4 radio buttons. So(80 radio buttons).

推荐答案

I have Total 20 ButtonGroups each with 4 radio buttons. So(80 radio buttons).

那么最简单的方法是

String actionCommand = "";
ButtonModel buttonModel = myButtonGroup.getSelection();
if (buttonModel != null) {
   actionCommand = buttonModel.getActionCommand();
} else {
   // buttonModel is null.
   // this occurs if none of the radio buttons 
   // watched by the ButtonGroup have been selected.
}
