What components can be reused inside a RecyclerView?

Inside RecyclerView, ViewHolder objects that contain references to interface elements (such as TextView, ImageView) for each list position can be reused. RecyclerView reuses these ViewHolders to avoid creating new views during scrolling, which significantly improves performance. It is also possible to reuse LayoutManager and ItemDecoration, but the key reusable component is the ViewHolder itself with its view components.

Example of ViewHolder:

class MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    val title: TextView = itemView.findViewById(R.id.title)
}

RecyclerView reuses instances of MyViewHolder when scrolling the list.
