Setting Image in onBindViewHolder for a RecyclerView-CodePudding

I'm trying to set up a RecyclerView on my HomeFragment and I'm at the point where I'm setting up the adapter. How do I set the image in my onBindViewHolder function? Do I need to refactor my category.java class to be able to actually set the image? Thank you!

In your category class you should use have url of image and the type of categoryImage should be String. then to load and show image in your onBindViewHolder use Glide
