Renderer RecyclerView 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;
• You can easily add the DiffUtil Payloads;
• You can easily save a state of a Item when scroll;
• You can easily add a Load More Indicator;
• Can be used without ViewHolder - use ViewBinder instead of ViewRenderer;
• Using this library will help you to follow SOLID principles.

Usage

• Step 1: Add the ViewModel interface to your UI model

public class SomeModel implements ViewModel {
	...
}

• Step 2: Create your item_layout

<LinearLayout ... >
	<TextView android:id = "@+id/title" ... />
	<ImageView android:id = "@+id/image" ... />
	<Button android:id = "@+id/button" ... />
	<CustomView android:id = "@+id/custom" ... />
</LinearLayout>

• Step 3: Initialize Adapter and register the ViewBinder

mRecyclerViewAdapter = new RendererRecyclerViewAdapter();

mRecyclerViewAdapter.registerRenderer(new ViewRenderer<>(
	R.layout.item_layout,
	SomeModel.class,
	(model, finder, payloads) -> finder
		.find(R.id.custom, (ViewProvider<CustomView>) customView -> { ... })
		.setBackground(R.id.image, model.getBackground())
		.setText(R.id.text, model.getText())
		.setOnClickListener(R.id.button, v -> { ... })
));

mRecyclerViewAdapter.registerRenderer(...); /* you can use several types of cells */

/* Regular code:
mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mRecyclerView.setAdapter(mRecyclerViewAdapter);

mRecyclerViewAdapter.setItems(getItems());
mRecyclerViewAdapter.notifyDataSetChanged();
*/
