I have a panel in which I put 2 radio buttons. I want to implement double click action on a radio button but it seems it doesn't work. In conclusion I want to make another component visible while double clicking one of the radio button, more precisely when clicking on its label.

Is there any explanation why the mouse listener works only if the radio buttons are disabled?

查看这段代码，我们在 JLabel/JTextField 中分隔单选按钮的文本

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.FocusAdapter;
import java.awt.event.FocusEvent;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.BorderFactory;
import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;

public class TestRadioButton {

    private void initUI() {
        JFrame frame = new JFrame(TestRadioButton.class.getSimpleName());
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        final JPanel panel = new JPanel();
        panel.setLayout(new BoxLayout(panel, BoxLayout.LINE_AXIS));
        final JRadioButton button = new JRadioButton();
        final JLabel label = new JLabel("Double click me");
        final JTextField editionTF = new JTextField();
        editionTF.setOpaque(false);
        editionTF.addFocusListener(new FocusAdapter() {
            @Override
            public void focusLost(FocusEvent e) {
                stopEdition(panel, label, editionTF);
            }

        });
        editionTF.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                stopEdition(panel, label, editionTF);
            }
        });
        label.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                if (e.getClickCount() == 2) {
                    startEdition(panel, label, editionTF);
                }
            }
        });
        editionTF.setBorder(BorderFactory.createEmptyBorder());
        editionTF.setFont(label.getFont());
        editionTF.setVisible(false);
        panel.add(button);
        panel.add(label);
        panel.add(editionTF);
        frame.add(panel, BorderLayout.NORTH);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    protected void stopEdition(final JPanel panel, final JLabel label, final JTextField editionTF) {
        label.setText(editionTF.getText());
        label.setVisible(true);
        editionTF.setVisible(false);
    }

    protected void startEdition(final JPanel panel, final JLabel label, final JTextField editionTF) {
        editionTF.setText(label.getText());
        label.setVisible(false);
        editionTF.setVisible(true);
    }

    public static void main(String[] args) {
        final TestRadioButton test = new TestRadioButton();
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                test.initUI();
            }
        });
    }
}

不是真正的答案，但评论太少了。使用以下代码，这对我来说很好。一定有其他问题你没有告诉我们。考虑发布SSCCE

import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JRadioButton;
import javax.swing.SwingUtilities;

public class TestRadioButton {

    private void initUI() {
        JFrame frame = new JFrame(TestRadioButton.class.getSimpleName());
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        final JRadioButton button = new JRadioButton("Double click me");
        button.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                if (e.getClickCount() == 2) {
                    SwingUtilities.invokeLater(new Runnable() {

                            @Override
                            public void run() {
                                 JOptionPane.showMessageDialog(button, "Radio button has been double clicked");
                            }
                    };
                }
            }
        });

        frame.add(button);
        frame.setSize(400, 400);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        final TestRadioButton test = new TestRadioButton();
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                test.initUI();
            }
        });
    }
}
