多个单选按钮被选中

Question

我有两个用java制作的单选按钮。问题是他们没有联系在一起，即他们都可以同时被选中。我如何实现他们之间的联系？

Answer 1

我认为你需要这一点;

 //Create three radio buttons 
     JRadioButton aButton = new JRadioButton("A",true); 
     JRadioButton bButton = new JRadioButton("B"); 
     JRadioButton cButton = new JRadioButton("C"); 

     //Create a ButtonGroup object, add buttons to the group 
     ButtonGroup myButtonGroup = new ButtonGroup(); 
     myButtonGroup.add(aButton); 
     myButtonGroup.add(bButton); 
     myButtonGroup.add(cButton); 

     //Display radio buttons 
     getContentPane().setLayout(new FlowLayout()); 
     getContentPane().add(aButton); 
     getContentPane().add(bButton); 
     getContentPane().add(cButton); 
     setSize(250,100); 
     setTitle("Swing Radio Buttons"); 
     setVisible(true); 

让我知道，如果帮助。

设置相同name属性 Radio example

<input id="hello" type="radio" name="greet"> 
<label for="hello">hello</label> 
<input id="hi" type="radio" name="greet"> 
<label for="hi">hi</label> 
<hr /> 
<input id="all" type="radio" name="who"> 
<label for="all">world!</label> 
<input id="one" type="radio" name="who"> 
<label for="one">you</label>
