I have an image from the web in an ImageView
. It is very small (a favicon) and I'd like to store it in my SQLite database.
I can get a Drawable
from mImageView.getDrawable()
but then I don't know what to do next. I don't fully understand the Drawable
class in Android.
I know I can get a byte array from a Bitmap
like:
Bitmap defaultIcon = BitmapFactory.decodeStream(in);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
defaultIcon.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] bitmapdata = stream.toByteArray();
But how do I get a byte array from a Drawable
?
Drawable d; // the drawable (Captain Obvious, to the rescue!!!)
Bitmap bitmap = ((BitmapDrawable)d).getBitmap();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] bitmapdata = stream.toByteArray();
