ListView images preloading im ImageView without delay (using Picasso or other libs)

I have the problem with image loading in listview. I'm using Picasso to load pictures from network into my imageViews in each row. When I'm scrolling first time there always white background before image loaded in its place. Even if I scroll very slow or even stop scrolling before new item is showing, there still white background showing before the image is loaded. Even if these pictures wasn't taken from the network, but already from cache (yellow indicator). But when these pictures already in memory (green indicator) pictures don't loading each time when scrolling, they already loaded into imageView, so I don't have this white background (or it may appear on fast scrolling, but it's ok).

This how I use Picasso in my adapter:

Picasso.with(context).load(url).fit().centerCrop().into(imageView);

I know this is complicated topic and we can have OOM, but there should be some variants, as I can see it implemented in popular social networks, so I guess it possible.

P.S. fetch() doesn't helped me in this case, changing fit() with harcoded resize(200, 200) method also doesn't helped.

Please write your thoughts without silent minusing this post. Thanks!

Picasso.with("Pass Context") //
            .load("Pass URL") //
            .transform(new RoundedTransformation(5, 0))
            .placeholder(R.drawable.*) //
            .error(R.drawable.*) //
            .fit() //
            .tag(mcontext) //
            .into("Your ImageView");
