Renderer Recycler View Adapter

  • 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 😊.

Example

Gradle

dependencies {
    compile 'com.github.vivchar:RendererRecyclerViewAdapter:+'
}

Usage

  • 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());
 }
 ...
}
