I had a similar problem   For this you can use a Hashmap which takes  string  and  object  as shown in code below       stores the image database icons    public static int   imageIconDatabase     R drawable ball          R drawable catmouse  R drawable cube  R drawable fresh          R drawable guitar  R drawable orange  R drawable teapot          R drawable india  R drawable thailand  R drawable netherlands          R drawable srilanka  R drawable pakistan      private void initializeImageList            TODO Auto-generated method stub     for  int i   0  i  lt  imageIconDatabase length  i              map   new HashMap lt String  Object gt              map put  Name   imageNameDatabase i            map put  Icon   imageIconDatabase i

As mentioned  one way is to use  new Integer my int value    But you should not call the constructor for wrapper classes directly  So  modify the code accordingly   mBitmapCache put Integer valueOf R drawable bg1  object
