你可以改變圖標像這樣....

希望這有助於...

menu.findItem(R.id.menu_search).setOnActionExpandListener(this); 
    // Your Activity/Fragment must implement the MenuItem.OnActionExpandListener interface 

    @Override 
    public boolean onMenuItemActionExpand(MenuItem item) { 
     getSherlockActivity().getSupportActionBar().setIcon(R.drawable.uvweb_logo); 
     return true; 
    }
