CellAdapter

This library simplifies RecyclerView with multiple view types. Main points:

  • Single adapter class for all project
  • Extend item types in RecyclerView - just register in adapter and extend Cell.class for mapping model with UI (below more details + sample)
  • Add any UI listeners to each item type

No more code like this:

@Override
public int getItemViewType(int position) {
 // Just as an example, return 0 or 2 depending on position
 return position % 2 * 2;
}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
 switch (viewType) {
  case 0: return new ViewHolder0(...);
  case 2: return new ViewHolder2(...);
  ...
 }
}

Usage

CellAdapter adapter = new CellAdapter(context);
//feel free to register multiple models and cells (model per cell, so your RecyclerView would represent multiple view types)
adapter.registerCell(Model.class, YourCell.class, new YourCell.Listener(){}); 

List items = new ArrayList();
items.add(new Model());
adapter.setItems(items);
adapter.notifyDataSetChanged();

where Model.class is POJO and YourCell.class is

@Layout(R.layout.your_cell_view)
public class YourCell extends Cell<Model, YourCell.Listener> {

  @Override
 protected void syncUiWithItem() {
  getItem() // is your Model object
 }
 
 protected void prepareForReuse() {
  //optional
 }
    
 protected void clearResources() {
  //optional
 }

 public interface Listener extends Cell.Listener<Model> {
  void callbackSample(Model model);
 }
}

Also please find CellAdapter/sample/src/main/java/io/techery/sample/BaseCell.java there is sample how to implement ButterKnife in Cells.
