java - 分页找不到当前位置

Question

我最近使用改造创建了一个带有 Api 的 recyclerview。我使用 OnScrollListener 进行了分页，它正在工作。但是当我点击某个文件时找不到它的位置，我该如何解决这个错误？

我在论坛中查看了有关它的信息，但没有找到与改造相关的任何内容。我只想选择文件并将其发送到另一个活动，以发送正确的 ID。

public class AcervoFragment extends Fragment {
    private Retrofit retrofit;
    private RecyclerView recyclerView;
    private AcervoAdaptador acervoAdaptador;
    private ProgressBar progressBar2;
    private List<Lancamentos> listaLancamentos = new ArrayList<>();
    private int pagina;
    private boolean aptoCarregar;

    public AcervoFragment() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_acervo, container, false);
        recyclerView = view.findViewById(R.id.recyclerViewAcervo);
        acervoAdaptador = new AcervoAdaptador(getActivity());
        recyclerView.setAdapter(acervoAdaptador);
