Production Application, how to retrieve data from firebase in recyclerview?

I'm developing an application and I'm in the employee listing and production part ("this listing in a single line in the recyclerview referring to the employee") but I'm having problems because I do not know how to bring the employee and the production because are two different node wanted to know how do I get the employee node and its production that is in the node production, I followed my code and my realtime in the firebase.

THIS IS MY REALTIME ON FIREBASE

publicclassFunctionalimplementsParcelable{

}

MyAdapterclass

publicclassMyAdapterextendsRecyclerView.Adapter{

privateContextcontext;privateList<Funcionario>f;privateList<Producao>p;publicMyAdapter(Contextcontext,List<Funcionario>f){this.context=context;this.f=f;notifyDataSetChanged();}publicMyAdapter(Contextcontext){this.context=context;}publicMyAdaptersetFuncList(List<Producao>producaos){this.p=producaos;notifyDataSetChanged();returnnull;}@OverridepublicViewHolderonCreateViewHolder(ViewGroupparent,intviewType){Viewv=LayoutInflater.from(context).inflate(R.layout.recycler_view_list_item,parent,false);returnnewViewHolder(v);}@OverridepublicvoidonBindViewHolder(ViewHolderholder,@SuppressLint("RecyclerView") final int position) {

    holder.textFuncao.setText(f.get(position).getFuncaoFuncionario());
    holder.textNome.setText(f.get(position).getNomeFuncionario());



}

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


class ViewHolder extends RecyclerView.ViewHolder {
    private ImageView ivFuncao;
    private TextView textFuncao;
    private TextView textNome;
    private TextView textRefProd;
    private TextView textTamProducao;
    private TextView textProcesso;
    private TextView textMeta;
    private TextView textCronometro;
    private TextView textDataHora;
    private TextView textTotalDia;

    ViewHolder(final View itemView) {

        super(itemView);

        ivFuncao = (ImageView) itemView.findViewById(R.id.iv_funcao);
        textFuncao = (TextView) itemView.findViewById(R.id.tv_funcao);
        textNome = (TextView) itemView.findViewById(R.id.tv_nome);
        textRefProd = (TextView) itemView.findViewById(R.id.tv_referencia_produto);
        textTamProducao = (TextView) itemView.findViewById(R.id.tv_produto_tam_producao);
        textProcesso = (TextView) itemView.findViewById(R.id.tv_processo);
        textMeta = (TextView) itemView.findViewById(R.id.tv_meta);
        textCronometro = (TextView) itemView.findViewById(R.id.tv_cronometro_tempo);
        textDataHora = (TextView) itemView.findViewById(R.id.tv_data_hora_dia);
        textTotalDia = (TextView) itemView.findViewById(R.id.tv_total_produzido);
    }
}

}

I'm using fragment so the snippet where I'm looking for the official in the FragmentA class

@Override     public void onStart () {         super.onStart ();         databaseFuncionario.addValueEventListener (new ValueEventListener () {

        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {

            mList.clear();

            for(DataSnapshot funcioSnapshot : dataSnapshot.getChildren()) {
                dataSnapshot.child(Constants.DATABASE_PATH_PRODUCAO);
                Funcionario f = funcioSnapshot.getValue(Funcionario.class);
                mList.add(f);
            }
            recyclerViewFuncionario = new RecyclerView(getContext());
            recyclerViewFuncionario = (RecyclerView) getView().findViewById(R.id.recycler_view);
            MyAdapter adapter = new MyAdapter(getContext(), mList);
            recyclerViewFuncionario.addOnItemTouchListener(new RecyclerViewTouchListener(getActivity(), recyclerViewFuncionario, FragmentA.this));
            recyclerViewFuncionario.setHasFixedSize(true);
            LinearLayoutManager layoutManager = new LinearLayoutManager(getContext());
            recyclerViewFuncionario.setLayoutManager(layoutManager);
            recyclerViewFuncionario.setAdapter(adapter);
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {
        }

    });
}

}

If any generous heart can help me, I thank you, remembering I can not list the employee in the recyclerview and the production by his id.
