I think this should solve your problem :

   final boolean evenClick = false;
   Button button = new Button("click");
   button.addListener(new ButtonListenerAdapter(){
   @Override
   public void onClick(Button button, EventObject e) {

        if (!evenClick) {
            hide();
        super.onClick(button, e);
                         }
         else {
       //DO YOUR SECOND CLICK STUFF
                }
        evenClick = !evenClick;     

    }

});
Window.add(button);
