Gradle Dependency

dependencies {
    compile 'io.github.luizgrp.sectionedrecyclerviewadapter:sectionedrecyclerviewadapter:1.0.4'
}

Basic usage:

1) Create a custom Section class extending StatelessSection
class MySection extends StatelessSection {

    List<String> myList = Arrays.asList("Item1", "Item2", "Item3");

    public MySection() {
        // call constructor with layout resources for this Section header and items 
        super(R.layout.section_header, R.layout.section_item);
    }

    @Override
    public int getContentItemsTotal() {
        return myList.size(); // number of items of this section
    }

    @Override
    public RecyclerView.ViewHolder getItemViewHolder(View view) {
        // return a custom instance of ViewHolder for the items of this section
        return new MyItemViewHolder(view);
    }

    @Override
    public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) {
        MyItemViewHolder itemHolder = (MyItemViewHolder) holder;

        // bind your view here
        itemHolder.tvItem.setText(myList.get(position));
    }
}
2) Create a custom ViewHolder for the section items:
class MyItemViewHolder extends RecyclerView.ViewHolder {

    private final TextView tvItem;
    
    public MyItemViewHolder(View itemView) {
        super(itemView);

        tvItem = (TextView) itemView.findViewById(R.id.tvItem);
    }
}
3) Set up your ReclyclerView with the SectionedRecyclerViewAdapter
// Create an instance of SectionedRecyclerViewAdapter 
SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();

// Add your Sections
sectionAdapter.addSection(new MySection());

// Set up your RecyclerView with the SectionedRecyclerViewAdapter
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerView.setAdapter(sectionAdapter);
