The searchview cancels the view (View) of search by filter, how to cancel the searchView?

I did not know how to formulate the question but I will try to be more explicit in the development; I have a searchView which I'm looking for in a recycleview merchandise. up there all ok.

searchView code

//CREAMOS MENU PARA BUSCAR ARTICULOS - Declaracion V7.SEARCHVIEW
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.searchfile, menu);
    final MenuItem myActionMenuItem = menu.findItem(R.id.search);
    searchView = (SearchView) myActionMenuItem.getActionView();


    changeSearchViewTextColor(searchView);
    ((EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text)).
            setHintTextColor(getResources().getColor(R.color.icons));
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            if (!searchView.isIconified()) {
                searchView.setIconified(true);
            }
            myActionMenuItem.collapseActionView();

            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            final List<ArticulosBean> filtermodelist = filter(list, newText);
            pAdapter.setfilter(filtermodelist);
            return true;
        }

    });

    return true;
}

Then the method to store the new list:

  //CREAMOS METODO DE TIPO LIST PARA RECIBIR LOS NUEVOS ARTICULOS SEGUN ESCRITURA
private List<ArticulosBean> filter(List<ArticulosBean> pl, String query) {
    query = query.toLowerCase();
    final List<ArticulosBean> filteredModeList = new ArrayList<>();
    for (ArticulosBean model : pl) {
        final String text = model.getName().toLowerCase();
        if (text.contains(query.toString())) {
            filteredModeList.add(model);
        }
    }
    return filteredModeList;
}

Well up here all right. with this I allow myself to do the searches on the list. The problem comes when I add an item to the menu to filter by item (eg Permfumeria, Bazaar, Drinks, etc).

    //METODO PARA LLENAR LA LISTA CON LOS ARTICULOS SEGUN RUBRO
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    switch (id) {
        case R.id.overflow: //NUEVO ITEM OVERFLOW

            final String[] arrays = getResources().getStringArray(R.array.rubros_item); //ARRRAY PREDEFINIDO

            AlertDialog.Builder builder = new AlertDialog.Builder(ScrollingActivity.this); //MUESTRO EL ARRAY EN UN ALERT DIALOG

            builder.setTitle("Elige un rubro:").setSingleChoiceItems(arrays, UNSELECTED, new DialogInterface.OnClickListener() { //UNSELECT = -1
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    selected = which;
                }
            }).setNegativeButton(android.R.string.cancel, null).setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    if (selected != UNSELECTED) {
                        list.clear(); //LIMPIO LISTA
                        listaArticuloPorRubro(arrays[selected].toString()); //LLENO SEGUN RUBRO
                        // Toast.makeText(getApplicationContext(), arrays[selected], Toast.LENGTH_SHORT).show();
                    }
                }
            });

            AlertDialog mDialog = builder.create();
            mDialog.show();

    }
    return super.onOptionsItemSelected(item);
}

If I search on the aforementioned search view, then this item does not answer me, that is, if I want to move to another list according to the heading, it does not update my view, it's like the searchview blocks it to the method:

This is the method that brings me the new list according to the heading:

 private void listaArticuloPorRubro(String rubro) {

    final String URLf = "https://www.servicioswebtsas.com/WebServicePedidos/lista_articulos_filtrado.php?rubro=" + rubro;
    final StringRequest stringRequest = new StringRequest(Request.Method.GET, URLf, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            try {
                JSONArray jsonArray = new JSONArray(response);
                for (int i = 0; i < jsonArray.length(); i++) {
                    ArticulosBean articulos = new ArticulosBean(jsonArray.getJSONObject(i).getString("nombre_articulo"), jsonArray.getJSONObject(i).getString("imagen_url"), //PUEDO PONER UN STRING GRACIAS A LA LIBRERIA PICASSO EN ADAPTER
                            jsonArray.getJSONObject(i).getDouble("precio"), jsonArray.getJSONObject(i).getInt("stock"));

                    list.add(articulos);

                }
                pAdapter.notifyDataSetChanged();
                //Toast.makeText(getApplicationContext(), jsonArray.toString(), Toast.LENGTH_SHORT).show();
            } catch (JSONException e) {
                Log.d("PENDRIVE", e.toString());
                e.printStackTrace();
            }

        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // Toast.makeText(getApplicationContext(), "ERROR: " + error, Toast.LENGTH_SHORT).show();
            Log.d("ERROR LISTA", error.toString());
        }
    });

    RequestQueue requestQueue = Volley.newRequestQueue(this);
    requestQueue.add(stringRequest);


}

I hope I have been clear! Thank you very much for your patience to read my problem.
