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.
