Basic

Basic adapter creation

SmartRecyclerAdapter
  .items(items)
  .map(MoviePosterModel::class, PosterViewHolder::class)
  .map(MovieBannerModel::class, BannerViewHolder::class)
  .map(MovieModel::class, MovieViewHolder::class)
  .map(TopNewsModel::class, TopNewsViewHolder::class)
  .add(OnClickEventListener { event: ViewEvent.OnClick -> 
    // Handle event
  })
  .into<SmartRecyclerAdapter>(recyclerView)

SmartViewHolder

Just extend your ViewHolder class with SmartViewHolder and pass in the target type ex SmartViewHolder<Mail>. Note that the constructor can both take View or ViewGroup as parameter, in this case PosterViewHolder(parentView: ViewGroup) to avoid casting to ViewGroup while inflating. The parentView is the recyclerView. The method unbind has an default implementation and is optional.

class PosterViewHolder(parentView: ViewGroup) : 
  SmartViewHolder<MovieModel>(parentView, R.layout.poster_item) {

  override fun bind(movie: MovieModel) {
    Glide.with(imageView)
      .load(model.posterUrl)
      .into(imageView)
  }

  override fun unbind() {
    Glide.with(imageView).clear(imageView)
  }
} 

Works with Android DataBinding! Just add the DataBinding LayoutInflater in super call. 🚀

class PosterViewHolder(parentView: ViewGroup) : 
  SmartViewHolder<MovieModel>(
    LayoutInflater.from(parentView.context)
      .inflate(R.layout.poster_item, parentView, false)
  )

Adapter creation with ViewTypeResolver

If you want to bind one data type with different view holders depending on some attribute you can set a ViewTypeResolver. Note .map() call not needed in this case but you can combine if you want to.

SmartRecyclerAdapter
  .items(items)
  .setViewTypeResolver{ item, position -> {
    when { 
      item is MovieTrailerModel -> MovieTrailerViewHolder::class
      item is MovieModel && item.isRatedR() -> RMovieViewHolder::class
      else -> MovieViewHolder::class // Add default view if needed, else SmartRecyclerAdapter will look at the base `.map` mapping
    }
  }}
  .into(recyclerView)

SmartEndlessScrollRecyclerAdapter

A popular feature in apps is to have endless scrolling with pagination, in other words load more items when user has scrolled to bottom. With SmartEndlessScrollRecyclerAdapter you can achieve this.

• setAutoLoadMoreEnabled defines if false load more button should be visible before loading.
• setLoadMoreLayoutResource can also set your custom loading/loadmore view.
• OnLoadMoreListener is called when scrolled to the last item and loading view is visible.

Create SmartEndlessScrollRecyclerAdapter

val endlessScrollAdapter: SmartEndlessScrollRecyclerAdapter = SmartEndlessScrollRecyclerAdapter
  .items(items)
  .setAutoLoadMoreEnabled(true)
  .setLoadMoreLayoutResource(R.layout.custom_loadmore_view)
  .setOnLoadMoreListener { adapter,  loadMoreViewHolder ->
    // Handle load more items
  }
  .map(MovieModel::class, MovieViewHolder::class)
  .into(recyclerView)

More SmartEndlessScrollRecyclerAdapter features

Enable/Disable endless scrolling and thus removing the loading view. endlessScrollAdapter.isEndlessScrollEnabled = false
