Error using a RecyclerView in Fragment - App was Stopped

Question

I am new here. But always resort to StackOverFlow to resolve my doubts. Almost always I can do that. But I cant find a solution to a problem that I'm having with use RecyclerView, filling it with Fragment. I do not have much experience in programming for Android. Thank you very much in advance.
