I don't see any reason to ask/answer questions like “I don't understand, help me!” anywhere.
I'm saying I don't understand what adapters and holders are and what they're used to. I lack some of the basics of android model view structure and I would like someone to explain the main points to me. Bc I've looked for videos and they're all about implementations, but if I don't understand the concept they're useless. I don't have a concrete detailed question bc I don't have knowledge.
