RecyclerView with Sugar ORM

I am beginner and I do not know how to populate and set up RecyclerView with Sugar database. I would appreciate yours help. Thank a lot. I have tried some tutorials but they did not work for me.

My Fragment

public class ContactListFragment extends Fragment {

    protected RecyclerView rvRecyclerView;
    RecyclerView.Adapter adapter;
    RecyclerView.LayoutManager layoutManager;



    public static ContactListFragment newInstance() {

        Bundle args = new Bundle();

        ContactListFragment fragment = new ContactListFragment();
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_contact_list, container, false);

        //recycler view setup
        rvRecyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
        //initialize recycler view here

        return view;
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        ButterKnife.bind(this, view);

        //show actionBar
        ((MainActivity) getActivity()).getSupportActionBar().show();
        //show title
        ((MainActivity) getActivity()).getSupportActionBar().setTitle(R.string.app_name);
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
    }
}

And ContactsAdapter (RecyclerAdapter)

public class ContactsAdapter extends RecyclerView.Adapter<ContactsAdapter.ContactsViewHolder> {

    ArrayList<Contact> arrayList = new ArrayList<>();
    static Context context;

    ContactsAdapter(Context context, ArrayList<Contact> arrayList) {
        this.arrayList = arrayList;
        this.context = context;
    }


    @Override
    public ContactsViewHolder onCreateViewHolder (ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_contact, parent, false);

        ContactsViewHolder contactsViewHolder = new ContactsViewHolder(view);
        return contactsViewHolder;
    }

    @Override
    public void onBindViewHolder(ContactsViewHolder holder, int position) {
        Contact contact = arrayList.get(position);
        holder.Name.setText(contact.getName());
    }

    @Override
    public int getItemCount() {
        return arrayList.size();
    }

    public static class ContactsViewHolder extends RecyclerView.ViewHolder {

        TextView Name;

        ContactsViewHolder(View view) {

            super(view);
            Name = (TextView)view.findViewById(R.id.contact_name);

        }
    }
}
