here is my code

            // First Menu Button
    menu.add("Help").setOnMenuItemClickListener(this.HelpButtonClickListener)
    .setIcon(R.drawable.help_button)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);


    // Second Menu Button
    menu.add("Like").setOnMenuItemClickListener(this.LikeButtonClickListener)
    .setIcon(R.drawable.like_button)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

    // Third Menu Button
    menu.add("Exit").setOnMenuItemClickListener(this.ExitButtonClickListener)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

    // Fourth Menu Button
    menu.add("Tab1").setOnMenuItemClickListener(this.Tab1ButtonClickListener)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

Answer 1

The addSubMenu method returns a SubMenu object. A SubMenu is also a Menu, so you can call add on it to add items to the submenu rather than the parent menu. Your code above is creating two different submenus for Form 1 and Form 2 rather than two items within a single New Form submenu.
