我不明白为什么它在片段中显示的问题：这是代码。2问题是由于我们在inflator中使用的return语句引起的。

public class Information extends Fragment {

    private RecyclerView deleteNoticeRecyler;
    private ArrayList<AlertData> list;
    private AlertsAdapter adapter;
    private DatabaseReference reference;

    private static final String ARG_PARAM1 = "param1";
    private static final String ARG_PARAM2 = "param2";

    private String mParam1;
    private String mParam2;

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

    public static Information newInstance(String param1, String param2) {
        Information fragment = new Information();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, param1);
        args.putString(ARG_PARAM2, param2);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1);
            mParam2 = getArguments().getString(ARG_PARAM2);
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_information, container, false);

        deleteNoticeRecyler = getView().findViewById(R.id.deleteNoticeRecycler);

        reference= FirebaseDatabase.getInstance().getReference().child("Notice");

        deleteNoticeRecyler.setLayoutManager(new LinearLayoutManager(getContext()));
        deleteNoticeRecyler.setHasFixedSize(true);

        getAlerts();

    return null;
    }
    private void getAlerts(){
        reference.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                list = new ArrayList<>();
                for(DataSnapshot snapshot  : dataSnapshot.getChildren()){
                    AlertData data = snapshot.getValue(AlertData.class);
                    list.add(data);
                }
                adapter = new AlertsAdapter(getContext(),list);
                adapter.notifyDataSetChanged();
                deleteNoticeRecyler.setAdapter(adapter);
            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

                Toast.makeText(getContext(),databaseError.getMessage() ,Toast.LENGTH_SHORT).show();
            }
        });
    }
}

我的问题的图片

由于这个问题，我的其他问题，我的其他问题有关的findViewbyid也是不工作。
