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.
• Using this library will protect you from the appearance of any business logic in an adapter :)

Gradle

• Step 1. Add the JitPack repository to your build file

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

• Step 2. Add the dependency

dependencies {
    compile 'com.github.vivchar:RendererRecyclerViewAdapter:1.0.9'
}

Usage

• Step 1. Implement SomeModel

public
class SomeModel implements ItemModel
{

	public static final int TYPE = 0;
	@NonNull
	private final String mTitle;

	public
	SomeModel(@NonNull final String title) {
		mTitle = title;
	}

	@Override
	public
	int getType() {
		return TYPE;
	}

	@NonNull
	public
	String getTitle() {
		return mTitle;
	}
	...
}

• Step 2. Implement SomeViewHolder

public
class SomeViewHolder
		extends RecyclerView.ViewHolder
{

	public final TextView mTitle;

	public
	SomeViewHolder(final View itemView) {
		super(itemView);
		mTitle = (TextView) itemView.findViewById(R.id.title);
		...
	}
}

• Step 3. Implement SomeViewRenderer

public
class SomeViewRenderer
		extends ViewRenderer<SomeModel, SomeViewHolder>
{
	public
	SomeViewRenderer(final int type, final Context context) {
		super(type, context);
	}

	@Override
	public
	void bindView(@NonNull final SomeModel model, @NonNull final SomeViewHolder holder) {
		holder.mTitle.setText(model.getTitle());
		...
	}

	@NonNull
	@Override
	public
	SomeViewHolder createViewHolder(@Nullable final ViewGroup parent) {
		return new SomeViewHolder(LayoutInflater.from(getContext()).inflate(R.layout.some_item, parent, false));
	}
}

• Step 4. Initialize Adapter and register the SomeViewRenderer

public
class SomeActivity
		extends AppCompatActivity
{

	private RendererRecyclerViewAdapter mRecyclerViewAdapter;
	private RecyclerView mRecyclerView;

	@Override
	protected
	void onCreate(final 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());
	}
	...
}
