Hello I come to you because I don't know how I can fill imageView depending on what I get from Json, there are moments when I get 8 images to load and other times I have to load 17 images. The problem is that I don't know how to do it correctly to load as many imageViews as the Json has. I'm using the Gson and Picasso libraries.

You need to use Recycler View for dynamic lists.
