How to press an element of the RecyclerView?

I have this activity that has a SwipeView with Tabs, each tab shows me 1 different fragment with a recyclerview with separate content separated into 4 categories: "food", "cinematographic", "music" and "others".

public class Lista_PreferenciaFragment extends Fragment {

BDHelper conn;


private OnFragmentInteractionListener mListener;
RecyclerView recyclerViewPref;
ArrayList<Preferencia> lista_pref;
String numero;
Detalle_Preferencia preferencias;
Adaptador_Preferencias adapter;
public Lista_PreferenciaFragment() {
    // Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    conn = new BDHelper(getContext(),"bd_vinculator",null,1);
    if (getArguments() != null) {

    }
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View vista = inflater.inflate(R.layout.fragment_lista__preferencia, container, false);
    lista_pref = new ArrayList<>();
    preferencias = new Detalle_Preferencia();
    SharedPreferences dato = PreferenceManager.getDefaultSharedPreferences(getContext());
    numero = dato.getString("numerito","");
    recyclerViewPref = (RecyclerView) vista.findViewById(R.id.recycler_pref);
    adapter = new Adaptador_Preferencias(lista_pref);
    adapter.setOnclickListener(new View.OnClickListener(){

        @Override
        public void onClick(View v) {
            Intent i = new Intent(getContext(),Recomendacion.class);
            preferencias.setGusto(lista_pref.get(recyclerViewPref.getChildAdapterPosition(v)).getGusto());
            preferencias.setNum_telef(numero);
            preferencias.setCod_cat("CO");
            Bundle mibundle = new Bundle();
            mibundle.putSerializable("detalle_pref",preferencias);
            i.putExtras(mibundle);
            startActivity(i);
        }
    });
    return vista;
}

private void llenarLista() {
    SQLiteDatabase db = conn.getReadableDatabase();
    Preferencia pref = null;
    lista_pref.clear();
    Cursor cursor = db.rawQuery("SELECT gusto FROM preferencia WHERE num_telef = '"+numero+"' AND cod_cat = 'CO'" ,null);
    while(cursor.moveToNext()){
        pref = new Preferencia();
        pref.setGusto(cursor.getString(0));
       lista_pref.add(pref);
    }
    db.close();
}

// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri) {
    if (mListener != null) {
        mListener.onFragmentInteraction(uri);
    }
}

@Override
public void onAttach(Context context) {
    super.onAttach(context);
    if (context instanceof OnFragmentInteractionListener) {
        mListener = (OnFragmentInteractionListener) context;
    } else {
        throw new RuntimeException(context.toString()
                + " must implement OnFragmentInteractionListener");
    }
}

@Override
public void onDetach() {
    super.onDetach();
    mListener = null;
}
public void onResume(){
    super.onResume();
    recyclerViewPref.setLayoutManager(new LinearLayoutManager(getContext()));
    llenarLista();
    recyclerViewPref.setAdapter(adapter);

public interface OnFragmentInteractionListener {

}

This is the tab code that shows the recycler of the category "food"

public class Adaptador_Preferencias extends RecyclerView.Adapter<Adaptador_Preferencias.PreferenciaViewHolder> implements View.OnClickListener {

ArrayList<Preferencia> list_pref;
private View.OnClickListener listener;

public Adaptador_Preferencias(ArrayList<Preferencia> list_pref) {
    this.list_pref = list_pref;

}

@Override
public PreferenciaViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.lista_pref,null,false);
    view.setOnClickListener(this);
    return new PreferenciaViewHolder(view);
}

@Override
public void onBindViewHolder(PreferenciaViewHolder holder, int position) {
    holder.preferencia.setText(list_pref.get(position).getGusto());

}

@Override
public int getItemCount() {
    return list_pref.size();
}
public void setOnclickListener(View.OnClickListener listener){
    this.listener = listener;
}
@Override
public void onClick(View view) {
    if (listener != null){
        listener.onClick(view);
    }
}

public class PreferenciaViewHolder extends RecyclerView.ViewHolder {
    TextView preferencia;

    public PreferenciaViewHolder(View itemView) {
        super(itemView);
        preferencia = (TextView) itemView.findViewById(R.id.txt_pref);


    }



}

Finally here I upload the adapter code of my recyclerview.
