I am new to the community and I have a problem, I want to implement the Endless Scroll or Infinite Scroll as some call it in a recycler view to load items, since I currently show the 11500 results in recycler view , this same within a fragment .
I forgot to comment that I use Butterknife .
This is my code in fragment :
private RecyclerView recyclerView;
private SolicitudesGeneradasAdapter adapter;
private RecyclerView.LayoutManager layoutManager;
private Call<SolicitudesGeneradasList> call;
private SolicitudesGeneradasService service;
private Unbinder unbinder;
@BindView(R.id.swipeSolicitudesGeneradas)
SwipeRefreshLayout swipeEventosRecientes;
@BindView(R.id.tvResultados)
TextView tvResultados;
public SolicitudesGeneradasFragment() {}
@Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_solicitudes_generadas, container, false);
unbinder = ButterKnife.bind(this, view);
service = API.getApi().create(SolicitudesGeneradasService.class);
call = service.obtenerSolicitudesGeneradas(API.KEY, getUUID());
swipeEventosRecientes.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
refresh();
}
});
call.enqueue(new Callback<SolicitudesGeneradasList>() {
@Override
public void onResponse(Call<SolicitudesGeneradasList> call, Response<SolicitudesGeneradasList> response) {
setSolicitudesGeneradas(response.body().getSolicitudes(), container, inflater);
}
@Override
public void onFailure(Call<SolicitudesGeneradasList> call, Throwable t) {
Toast.makeText(getActivity(), "Al parecer algo salio mal", Toast.LENGTH_SHORT).show();
}
});
return view;
}
private void setSolicitudesGeneradas(final ArrayList<SolicitudesGeneradas> solicitudes, ViewGroup container, LayoutInflater inflater) {
recyclerView = (RecyclerView) container.findViewById(R.id.recyclerView);
adapter = new SolicitudesGeneradasAdapter(solicitudes, R.layout.recycler_view_manttos_correctivos, new SolicitudesGeneradasAdapter.OnItemClickListener() {
@Override
public void onItemClick(String idSolicitud, int position) {
Intent intent = new Intent(getActivity(), DetalleSolicitudActivity.class);
intent.putExtra("idSolicitud", idSolicitud);
startActivity(intent);
}
});
layoutManager = new LinearLayoutManager(inflater.getContext());
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(adapter);
tvResultados.setText(Integer.toString(solicitudes.size()) + " Resultados");
}
@OnClick(R.id.tvFiltros)
public void filtros() {
Toast.makeText(getActivity(), "Has pulsado los filtros!", Toast.LENGTH_SHORT).show();
}
private void refresh() {
getFragmentManager()
.beginTransaction()
.detach(SolicitudesGeneradasFragment.this)
.attach(SolicitudesGeneradasFragment.this)
.commit();
}
public String getUUID() {
String uuid;
uuid = Settings.Secure.getString(getActivity().getContentResolver(), Settings.Secure.ANDROID_ID);
return uuid;
}
@Override
public void onDestroyView() {
super.onDestroyView();
unbinder.unbind();
}
}
This is the code of my Adapter:
public class SolicitudesGeneradasAdapter extends RecyclerView.Adapter<SolicitudesGeneradasAdapter.ViewHolder> {
private ArrayList<SolicitudesGeneradas> solicitudesGeneradas;
private int layout;
public OnItemClickListener itemClickListener;
public SolicitudesGeneradasAdapter(ArrayList<SolicitudesGeneradas> solicitudes, int layout, OnItemClickListener listener) {
this.solicitudesGeneradas = solicitudes;
this.layout = layout;
this.itemClickListener = listener;
}
@Override
public SolicitudesGeneradasAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(layout, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
}
@Override
public void onBindViewHolder(SolicitudesGeneradasAdapter.ViewHolder holder, int position) {
SolicitudesGeneradas solicitudesGeneradas = this.solicitudesGeneradas.get(position);
holder.bind(solicitudesGeneradas.getIdSolicitud(),
solicitudesGeneradas.getNombreSucursal(),
solicitudesGeneradas.getFechaRegistro(),
solicitudesGeneradas.getFolioSolicitud(),
solicitudesGeneradas.getNivel(),
solicitudesGeneradas.getSubcategoriaDescripcion(),
solicitudesGeneradas.getUltimoStatus(),
itemClickListener);
}
@Override
public int getItemCount() {
return solicitudesGeneradas.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
@BindView(R.id.tvNombreSucursal)
TextView tvNombreSucurusal;
@BindView(R.id.tvFechaHoraRegistro)
TextView tvFechaHoraRegistro;
@BindView(R.id.tvFolio)
TextView tvFolio;
@BindView(R.id.tvNivelEstatus)
TextView tvNivelEstatus;
@BindView(R.id.tvSubcategoriaDescripcion)
TextView tvSubcategoriaDescripcion;
@BindView(R.id.tvEstatus)
TextView tvEstatus;
public ViewHolder(View itemView) {
super(itemView);
ButterKnife.bind(this, itemView);
}
public void bind(final String id, final String sucursal, final String fechaRegistro, final String folio, final String nivel, final String subcategoriaDescripcion, final String ultimoEstatus, final OnItemClickListener listener) {
tvNombreSucurusal.setText(sucursal);
tvFechaHoraRegistro.setText(fechaRegistro);
tvFolio.setText(folio);
tvNivelEstatus.setText(nivel);
tvSubcategoriaDescripcion.setText(subcategoriaDescripcion);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
listener.onItemClick(id, getAdapterPosition());
}
});
tvEstatus.setText(ultimoEstatus);
}
}
public interface OnItemClickListener {
void onItemClick(String name, int position);
}
The truth is that I have followed several tutorials, but I do not load, I do not know if I'm wrong or I'm wrong, I thought if I have to put a LIMIT in my MySQL query and go passing the amount that I want to add as if it were the pagination of a website.
I hope you have explained me well, anyway I appreciate your attention.
Thank you!
