- Now you do not need to implement adapters for RecyclerView;
- You can easily use several types of cells in a single list;
- You can reuse cells in different RecyclerView;
- You can easily add a nested RecyclerView;
- You can easily add the DiffUtil support;
- Using this library will protect you from the appearance of any business logic in an adapter 😊.

}
- Step 1. Implement SomeModel
public class SomeModel implements ItemModel {
public static final int TYPE = 0;
private String mTitle;
public SomeModel(String title) {
mTitle = title;
}
@Override
public int getType() {
return TYPE;
}
public String getTitle() {
return mTitle;
}
...
}
- Step 2. Implement SomeViewHolder
public class SomeViewHolder extends RecyclerView.ViewHolder {
public TextView mTitle;
public SomeViewHolder(View itemView) {
super(itemView);
mTitle = (TextView) itemView.findViewById(R.id.title);
...
}
}
- Step 3. Implement SomeViewRenderer
public class SomeViewRenderer extends ViewRenderer<SomeModel, SomeViewHolder> {
public SomeViewRenderer(int type, Context context) {
super(type, context);
}
@Override
public void bindView(SomeModel model, SomeViewHolder holder) {
holder.mTitle.setText(model.getTitle());
...
}
@Override
public SomeViewHolder createViewHolder(ViewGroup parent) {
return new SomeViewHolder(inflate(R.layout.some_item, parent));
}
}
- Step 4. Initialize Adapter and register the SomeViewRenderer
public class SomeActivity extends AppCompatActivity {
private RendererRecyclerViewAdapter mRecyclerViewAdapter;
private RecyclerView mRecyclerView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mRecyclerViewAdapter = new RendererRecyclerViewAdapter();
mRecyclerViewAdapter.registerRenderer(new SomeViewRenderer(SomeModel.TYPE, this));
mRecyclerViewAdapter.registerRenderer(...); /* you can use several types of cells */
mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mRecyclerView.setAdapter(mRecyclerViewAdapter);
mRecyclerViewAdapter.setItems(getItems());
mRecyclerViewAdapter.notifyDataSetChanged();
//Or you can use method with the DiffUtil support
//mRecyclerViewAdapter.setItems(getItems(), new YourDiffCallBack());
}
...
