Sqlite Data Does Not Appear in RecyclerView

I'm trying to list data in a RecyclerView, but on the 3 lines nothing appears and I do not know what's wrong, so look at the image below:

AdapterClient.java

    View v=mLayoutInflater.inflate(R.layout.item_cliente, parent, false);
    MyViewHolder mvh = new MyViewHolder(v);
    return mvh;
}

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    Log.i("LOG","onBindViewHolder()");
    holder.tvNome.setText(listacliente.get(position).getNom_cli());
}

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

public class MyViewHolder extends RecyclerView.ViewHolder{
    public TextView tvNome;
        public MyViewHolder(View itemView) {
            super(itemView);
            tvNome=(TextView) itemView.findViewById(R.id.textViewNom);
        }
    }
}
