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

I think the reason is that Picasso caches your images but since you have a list of drawables that you bundle together with your app, you do not in theory need to cache your images. Caching is only useful when you are downloading the image from the internet and you don't want the app to redownload the images each time you swipe up or down on the recyclerview.

I would adjust the way picasso works by changing the memorypolicy so try this instead :

 Picasso.with(getContext()).load(data.get(pos).getFeed_thumb_image()).memoryPolicy(MemoryPolicy.NO_CACHE).into(image);
