Extremely Laggy RecyclerView Performance
I was having the same problem with RecyclerView. It was laggy. In my case, there was a horizontal list of image buttons inside RecyclerView.
I solved it by removing the scaleType
from ImageButtons
or ImageViews
and loading images through Picasso with resizing
like :
Picasso.with(context).load(icon.get(position)).resize(270,270).centerCrop().into(holder.iconView);
The problem of lag may occur due to runtime scaling of big sized images or no. of images. It is not advisable. Whereas Picasso takes care of resizing, and loading efficiently. Also it handles caching for you.
