Searchview with Recyclerview in Android using Volley per pagin How to add search filters to the last page in a recycler view that consumes ten page?

I am doing a search filter by identity document in a Recyclerview that is per page, the problem is that at the time of making the filter it only looks for the first diez that is the current page. How would I filter the search from the current page until last page?

RecyclerActasAdapter.java

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

    public void filtrar(String query) {
        this.itemsMostrados = new ArrayList<>();

        if (query.length() == 0) {
            itemsMostrados = listaActas;
            layoutResultados.setVisibility(View.GONE);
        } else {
            ActasActivity actas= new ActasActivity();
            for (Datum data: listaActas) {
                if (data.getBeneficiario().getNumDocumento().contains(query)
                    //|| (data.getBeneficiario().getNombre().toLowerCase() + " " + data.getBeneficiario().getApellido().toLowerCase()).contains(text.toLowerCase())
                    || (data.getBeneficiario() != null ? data.getBeneficiario().getNombre() : "No registra" + " " + data.getBeneficiario() != null ? data.getBeneficiario().getApellido() : "No registra").contains(query)
                    //|| data.getPoblacion().getNombre().toLowerCase().contains(text.toLowerCase())
                    //|| data.getMunicipio().getMunicipio().toLowerCase().contains(text.toLowerCase())
                    ) {
                    itemsMostrados.add(data);

                }
            }

            layoutResultados.setVisibility(View.VISIBLE);
            txtResults.setText(itemsMostrados.size() + "");

        }

        notifyDataSetChanged();
    }

    public void actualizar() {
        itemsMostrados = listaActas;
        notifyDataSetChanged();
    }

ActasActivity.java

In this activity I try to create the condition to filter search to the last page but still continue to filter only the first 10 of the current page

  public void obtenerActas(boolean inicializar) {

        if (inicializar) {
            current_page = 1;
            last_page = 1;
            last_size_pages = 0;
        }

        final Promise<RespuestaActasDTO, BusinessException, RespuestaActasDTO> mPromise = actasService.obtenerActas(current_page);
        mPromise.done(result -> {
            if (progressDialog.isShowing()) {
                progressDialog.dismiss();
            }

            actualizarListadoActas(result, inicializar);

            if (progressBar.getVisibility() == View.VISIBLE) {
                progressBar.setVisibility(View.GONE);
            }

        });
        mPromise.fail(error -> {
            if (progressDialog.isShowing()) {
                progressDialog.dismiss();
            }

            if (progressBar.getVisibility() == View.VISIBLE) {
                progressBar.setVisibility(View.GONE);
            }

            Toast.makeText(mContexto, "Ocurrió un error consultando las actas", Toast.LENGTH_SHORT).show();
        });
    }

    public void actualizarListadoActas(RespuestaActasDTO respuestaActasDTO, boolean inicializar) {

        // logica para controlar la pagina a consumir y saber cual es la ultima pagina
        last_page = respuestaActasDTO.getLastPage();

        //SI PAGINA ACTUAL ES MENOR QUE ULTIMA PAGINA
        if (current_page < last_page) {
            current_page++;//ENUMEREME DESDE LA PAGINA ACTUAL

        }

        if (actasAdapter == null || inicializar) {
            listaActas = new ArrayList<>();
            listaActas = respuestaActasDTO.getData();

            recyclerViewActas.setAdapter(actasAdapter);

                    listaActas.addAll(ultimaLista);
                    actasAdapter.actualizar();
                }
            }
        }
        // Logical END to control the page to consume and know which is the last page ------>>>>


        if (agregarEventoBuscar) {
            agregarEventoBuscar = false;
            // buscador
            inputBuscar.setOnQueryTextListener( new SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    actasAdapter.filtrar(inputBuscar.getQuery().toString() );
                    return true;
                }

                @Override

                }
            } );

        }

Observation: I only filter the query if I scroll to the last page, Thanks for your support

java – How can I create a filter with SearchView javarecyclerviewAndroid Studio?

I watched PDF and YouTube tutorials for hours and it never came out. I can get the error "Why don't I understand it?" Not found.

I am a beginner in Android Studio and do not see the errors at first. I know the search engine code isn't complete, but I'm already desperate and I can't think of anything else.

java – How to filter a search with SearchView?

I'm setting up an application that displays a list of registered users in a specific activity ListView, This activity also has one Search View which serves to filter the data of ListView according to the written text. I would like to know how to filter this information.

Search View XML code:

activity code

protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState);
setContentView (R.layout.activity_accounts);
listAccountsAux = (ListView) findViewById (R.id.listAuxAccounts);
svContasAux = (SearchView) findViewById (R.id.sv_aux);
svCardContasAux = (CardView) findViewById (R.id.sv_card_aux);

svCardContasAux.setOnClickListener (new View.OnClickListener () {
@Run over
public void onClick (View v) {
svContasAux.setIconified (false);
