我试图从我的android设备中选择一个文件，我启动意图，当在弹出窗口中单击特定按钮（pasirinktiFela按钮）时，我可以选择我的文件，然后我试图通过Log.d（）查看选择的内容，但它没有显示结果。
下面是我的片段类KorepetitoriuiPatvirtintiMokiniai，它有onActivityResult方法。

public class KorepetitoriuiPatvirtintiMokiniai extends Fragment {

    private RecyclerView recyclerView;
    private ArrayList<KorepetitoriuiPatvirtintasMokinysKortele> arrayList;
    private KorepetitoriuiPatvirtintiMokiniaiCardAdapter adapter;

    }

    public static KorepetitoriuiPatvirtintiMokiniai newInstance() {
        KorepetitoriuiPatvirtintiMokiniai fragment = new KorepetitoriuiPatvirtintiMokiniai();
        Bundle args = new Bundle();
        fragment.setArguments(args);
        return fragment;
    }

    @Override

        recyclerView = view.findViewById(R.id.recyclerKorepetitoriuiPatvirtintiMokiniai);
        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(this.getContext()));
        emptyRecycler = view.findViewById(R.id.neraMokiniuKorepetitoriui);

        arrayList = new ArrayList<KorepetitoriuiPatvirtintasMokinysKortele>();

        GautiPatvirtintusMokiniusTask task = new GautiPatvirtintusMokiniusTask(prisijungti.currentKorepetitorius.getId());
        task.execute();

        return view;
    }

                    arrayList.add(new KorepetitoriuiPatvirtintasMokinysKortele(vardasMokinio, mokinioId));

我的适配器类：

我的保持器类别：

public class KorepetitoriuiPatvirtintiMokiniaiCardHolder extends RecyclerView.ViewHolder{
    
        public static TextView mokinioVardas;
        public static Button parasyti, pridetiMedziaga;
    
        public KorepetitoriuiPatvirtintiMokiniaiCardHolder(@NonNull View itemView) {
            super(itemView);
    
            mokinioVardas = itemView.findViewById(R.id.vardasKorteleMokinioPatvirtintas);
            parasyti = itemView.findViewById(R.id.korepetitoriusParasyti);
            pridetiMedziaga = itemView.findViewById(R.id.korepetitoriusPridetiMedziaga);
        }
    }

我做错什么了吗？
试图通过在我的Android应用程序中单击按钮从我的Android设备中获取文件，并检查所选文件是否实际上是通过日志选择的，没有得到任何结果。
