A Problem on removing a ActionListener

Question

In my program, due to the structure constraint, I have one action listener attached to a button in one place. And in somewhere else of my code I have to attach another action listener to this button, in this listener's actionPerformed method, I need to prevent the actionListener which I attached earlier being triggered. but I always fail to do so, here is a simplied code which can describe my situation.
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
public class ListenerTest {
public ListenerTest(){
     final JButton button=new JButton();
     final Listener l=new Listener();
     button.addActionListener(l);
     button.addActionListener(new ActionListener(){;
     public void actionPerformed(ActionEvent e){
          System.out.println("listener 2");
          button.removeActionListener(l);
     button.doClick();
private class Listener implements ActionListener{
     public void actionPerformed(ActionEvent e){
          System.out.println("listenr 1");
public static void main(String[] args){
     ListenerTest test=new ListenerTest();
}while run into the listener 2, I want prevent the trigger of listener 1, by using removeActionListener here, I can not get my expected effect, don't know how to do? Thanks in advance

for example:
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class ListenerTest2 {
   private static void createAndShowUI() {
      JPanel panel = new JPanel(new BorderLayout());
      final LTPanel ltPanel = new LTPanel();
      final ActionListener newListener = new ActionListener() {
         public void actionPerformed(ActionEvent e) {
            System.out.println("Now the *new* action listener is active");
      JToggleButton listenerToggle = new JToggleButton("Listener Toggle");
      listenerToggle.addActionListener(new ActionListener() {
         private ActionListener[] allAListeners;
         public void actionPerformed(ActionEvent e) {
            JToggleButton toggleBtn = (JToggleButton)e.getSource();
            JButton button = ltPanel.getButton();
            if (toggleBtn.isSelected()) {
               allAListeners = button.getActionListeners();
               for (ActionListener aListener : allAListeners) {
                  button.removeActionListener(aListener);
               button.addActionListener(newListener);
            else {
               button.removeActionListener(newListener);
               for (ActionListener aListener : allAListeners) {
                  button.addActionListener(aListener);
      panel.add(ltPanel, BorderLayout.CENTER);
      panel.add(listenerToggle, BorderLayout.SOUTH);
      JFrame frame = new JFrame("ListenerTest2");
      frame.getContentPane().add(panel);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.pack();
      frame.setLocationRelativeTo(null);
      frame.setVisible(true);
   public static void main(String[] args) {
      java.awt.EventQueue.invokeLater(new Runnable() {
         public void run() {
            createAndShowUI();
class LTPanel extends JPanel {
   private JButton button = new JButton("Button");
   public LTPanel() {
      button.addActionListener(new ActionListener() {
         public void actionPerformed(ActionEvent e) {
            System.out.println("The original action listener is active");
      add(button);
   public JButton getButton() {
      return button;
}
