RecyclerView laggy scrolling

Question

I am loading 400x200 images in RecyclerView, but scrolling is laggy on 2k devices. I am using Picasso for loading images from resource.

As you can see in the demo ima

Answer 1

This could be because of Picasso taking time to load the image. Use the below snapshot and adjust accordingly.

Picasso.with (context)
                    .load (url).fit().centerCrop()
                    .error (R.drawable.UserImage)         
                    .into (imageView);

Use fit() and centerCrop() to avoid legginess.
