It will work if you instantiate ScratchImageView by using findViewById. Please take a look at the snippet below:
ScratchImageView scratchImageView = (ScratchImageView) findViewById(R.id.sample_image);
Resources resources = getResources();
final int resourceID = resources.getIdentifier(b.getString("promoCode"), "drawable", getPackageName());
scratchImageView.setImageDrawable(resources.getDrawable(resourceID, null));
