How to get the Dimensions of a Drawable in an ImageView? [duplicate]

Answer 1

this solved my problem. It decode the size of image boundary without really load the whole image.

BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
Bitmap bmp = BitmapFactory.decodeResource(this.getResources(), R.drawable.img , o);
int w = o.outWidth;
int h = o.outHeight;
