HelpItemAdapter

class HelpItemAdapter(context: Context, data: List<HelpData>, armadilloViewModel: ArmadilloViewModel, lifecycleOwner: LifecycleOwner) : RecyclerView.Adapter<HelpItemAdapter.HelpItemViewHolder>

RecyclerView adapter used to display the list of help resources for the current Fragment.

The adapter manages the RecyclerView HelpItemViewHolders and binds the values from the help resource list to the holders. If a holder is currently (re)usable, the current help resource is bound to it. If no holder is (re)usable, a new one is created and the current help resource is then bound to it. As soon as the user scrolls further and a Holder leaves the screen, it is no longer needed to display its current content and can be reused by binding a new content to it.
