If your drawble is not always an instanceof BitmapDrawable

Note: ImageView should be set before you do this.

Bitmap bitmap;
if (mImageView.getDrawable() instanceof BitmapDrawable) {
    bitmap = ((BitmapDrawable) mImageView.getDrawable()).getBitmap();
} else {
    Drawable d = mImageView.getDrawable();
    bitmap = Bitmap.createBitmap(d.getIntrinsicWidth(), d.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    d.draw(canvas);
}

Your bitmap is stored in bitmap.

Voila!
