I learned it here.
From the code you've posted, it looks like you're just creating the Bitmap and not actually drawing anything into it. You can generate a bitmap of your view group by force-building the drawing cache of your view and pulling the image from the cache. Then, you should be able to add the Bitmap to your ImageView. See the example below:
viewGroup.buildDrawingCache();
Bitmap viewGroupBitmap = viewGroup.getDrawingCache();
image.setImageBitmap(viewGroupBitmap);
Hope this helps.
