java - 如何在同一行显示单选按钮和标签？

Question

private String[] gender = {"Male","Female"};

private JComboBox jco = new JComboBox();

private JRadioButton[] jrbGender;
private ButtonGroup buttonGroup = new ButtonGroup();

private JButton jbtAdd = new JButton("Create");
private JButton jbtRetrieve = new JButton("Retrieve");
private JButton jbtUpdate = new JButton("Update");
private JButton jbtDelete = new JButton("Delete");

public RegistrationForMembership(){


    JPanel jp1 = new JPanel(new GridLayout(6,2));
    JPanel jp2 = new JPanel(new FlowLayout());
    JPanel jp3 = new JPanel(new GridLayout(1,1));

    jco = new JComboBox(membership);
    jrbGender = new JRadioButton[gender.length];

    add(jp1);

    jp1.add(new JLabel("Member ID"));
    jp1.add(jtfID);
    jp1.add(new JLabel("Member Name"));
    jp1.add(jtfName);
    jp1.add(new JLabel("Member IC"));
    jp1.add(jtfIC);
    jp1.add(new JLabel("Address"));
    jp1.add(jtfAddress);
    jp1.add(new JLabel("Gender"));

    for(int i =0; i<gender.length;++i){
        jrbGender[i] = new JRadioButton(gender[i]);
        buttonGroup.add(jrbGender[i]);
      jp1.add(jrbGender[i]);

    }

    add(jp1);

其中一个单选按钮会转到下一行，如何让单选按钮与标签在同一行？

Answer 1

将 JRadioButton 添加到新的 JPanel 并将其添加到 jp1。

JPanel radios = new JPanel();
for (int i = 0; i < gender.length; ++i){
    jrbGender[i] = new JRadioButton(gender[i]);
    buttonGroup.add(jrbGender[i]);
    radios.add(jrbGender[i]);
}
jp1.add(radios);

此外，看起来 jp1 应该有 5 行，而不是 6 行。

JPanel jp1 = new JPanel(new GridLayout(5,2));
