have try set scaletype after image has been loaded?

   mpicasso.load("yoururl")                     .into(yourimageview, new callback() {                         @override                         public void onsuccess() {                             yourimageview.setscaletype(imageview.scaletype.center_crop);//or scaletype.fit_center                         }                         @override                         public void onerror() {                             //nothing                         }                     });
