Check this stackoverflow.com/questions/8880376/… - Aniruddha
You can use int finalHeight = iv.getMeasuredHeight(); int finalWidth = iv.getMeasuredWidth();, where iv is your ImageView object. - Aniruddha
@Aniruddha it just work after loading image in imageview ! but i want to know image size befor loading that - user2549089

You can get Bitmap dimensions only after downloading It - you must use synchronous method call like this:

final Bitmap image = Picasso.with(this).load("http://").get();
int width = image.getWidth();
int height = image.getHeight();

After this you can call again load with same url (It will be fetched from cache):

 Picasso.with(this).load("http://").into(imageView)

Edit: Maybe better way:

 Picasso.with(this).load("http://").into(new Target() {
            @Override
            public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                int width = bitmap.getWidth();
                int height = bitmap.getHeight();
                imgView.setImageBitmap(bitmap);
            }

            @Override
            public void onBitmapFailed(Drawable errorDrawable) {

            }

            @Override
            public void onPrepareLoad(Drawable placeHolderDrawable) {

            }
        });

Work for me.

Picasso.with(context).load(imageLink).into(imageView, new Callback() {
        @Override
        public void onSuccess() {
            Picasso.with(context).load(imageLink).into(new Target() {
                @Override
                public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                    int width = bitmap.getWidth();
                    int height = bitmap.getHeight();
                    Log.d("ComeHere ", " W : "+ width+" H : "+height);
                }

                @Override
                public void onBitmapFailed(Drawable errorDrawable) {

                }

                @Override
                public void onPrepareLoad(Drawable placeHolderDrawable) {

                }
            });

        }

        @Override
        public void onError() {

        }
    });
