Is it possible to hack around and preload images in a recycler view with this right now?

Absolutely, you just need to call the existing preloader's onScroll method will all of the required values other than the AbsListView. If you're using LinearLayoutManager or GridLayoutManager, you can use this gist: https://gist.github.com/sjudd/0776594543c4b6c30d38

This would be wonderful. I'm currently manually calling Glide on each item inside the adapter, but this looks cleaner.

@Saketme You'd still need to call Glide on each item in the adapter. The preloader only loads items into memory, not into views. The preloader is a performance improvement that prevents users from seeing images loading while they scroll (assuming the images can be loaded at least as fast as the user is scrolling).

Without the preloader, since you only request images when the view is rendered, the image doesn't start loading until the user can see the view, and so the user will always see a loading indicator.

@sjudd That's exactly what I'm doing. Sorry if I wasn't clear enough in my previous post, but I'm currently calling Glide only to preload them into memory using downloadOnly() :D
