Hi,
I found an answer to my previous question (the code for it is attached
below).
i think the solution is not too elegant so if you have any input on how i
can make it less hard coded i would love to hear it
for example i would like to set the name of the original image with xml and
also the coordinated that i would like to crop from it. and then be able to
extract this information from the parser. what would be the best method of
doing that?
if anyone is interested here is the code i used to get there:
Bitmap orgBmp = BitmapFactory.decodeResource(res,
R.drawable.sym_keyboard_delete);
Bitmap cropedBitmap = Bitmap.createBitmap(orgBmp, 0, 0, 20, 10);
BitmapDrawable bitMapDraw = new BitmapDrawable(cropedBitmap);
key.icon= bitMapDraw;
