        public void onChildViewAdded(View parent, View child) {
            float scale = context.getResources().getDisplayMetrics().density;

            int maxHeightDp = (int) (maxHeightPixels * scale + 0.5f);

            if (child instanceof ImageView) { //Images
                ImageView imageView = (ImageView) child;
                imageView.setAdjustViewBounds(true);
                imageView.setMaxHeight(maxHeightDp);

            } else { //Videos
                ViewGroup.LayoutParams params = child.getLayoutParams();
                params.height = maxHeightDp;
                child.setLayoutParams(params);
            }
        }

        @Override
        public void onChildViewRemoved(View parent, View child) {}
    });
