How does the RecyclerView work? Imagine you're looking at a long list on your phone, like a list of 1000 contacts or messages. Creating a view (like a row) for every single item would be super slow and use up a lot of memory. RecyclerView is the solution. Instead of making 1000 rows at once, it only creates the few rows that can fit on your screen right now - maybe 10 or so. As you scroll, it does something even better, when a row scrolls off the screen, it doesn't throw that row away. Instead, it reuses that same row by changing its content to show the new row to the users. Think of it like a conveyor belt of views. As you scroll down, the rows at the top disappear and get "recycled" - their graphics and text are updated with new information for the rows coming into view at the bottom. This means the app uses less memory and scrolls much more smoothly. This recycling process occurs within the onBindViewHolder() method. Initially, you'll receive unused view holders that need to be populated with the data you want to display. As scrolling continues, you'll start receiving view holders from rows that have scrolled off-screen. At this point, you'll replace the old data these holders contained with new, relevant information. So RecyclerView is an efficient way of showing long lists, creating only the views you need and reusing them over and over again. This is how the RecyclerView works.
