更改RecyclerView适配器后更新片段

Question

当用户握住RecyclerView并将其从数据库中删除时，我正在尝试更新片段上的itemview。

我看到了许多答案，并尝试了一些实现，但均未成功。我已经尝试过notify()方法。我不确定如何处理这个问题，也不确定我尝试的方法是否可行。该对象确实删除，并且在重新加载片段时，该项目已消失。有人可以帮忙吗？

这是适配器：

public void onBindViewHolder(MyViewHolder holder, @SuppressLint("RecyclerView") final int position) {
    final OfflineModule model = assList.get(position);
    holder.textView_name.setText(model.getCode());
    holder.textView_bio.setText(model.getDesc());
    holder.txtIDMod.setText(model.getId());        
    holder.itemView.setOnLongClickListener((View v) ->{
        // Use the Builder class for convenient dialog construction
        AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
        builder.setMessage("Delete " + model.getCode() + "?")
                .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        RealmHelper helper;
                        Realm realm;
                        // initialize realm
                        Realm.init(mContext);
                        //SETUP REEALM
                        RealmConfiguration defaultConfig = new RealmConfiguration.Builder()
                                .schemaVersion(0)
                                .build();
                        realm=Realm.getInstance(defaultConfig);
                        helper = new RealmHelper(realm);
                        List<FAssessment> assessmentList =helper.retrieveAF(model.getId());
                        assert assessmentList != null;
                        realm.executeTransaction(new Realm.Transaction() {
                            @Override
                            public void execute(Realm realm) {
                                for(FAssessment a : assessmentList) {
                                    a.deleteFromRealm();
                                }
                            }
                        });
                        OfflineModule result = realm.where(OfflineModule.class)
                                .equalTo("code", model.getCode()).findFirst();
                        assert result != null;
                        realm.executeTransaction(new Realm.Transaction() {
                            @Override
                            public void execute(Realm realm) {
                                result.deleteFromRealm();
                            }
                        });
                    }
                })
                .setNegativeButton("No", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                    }
                });
        builder.create();
        builder.show();
        return true;
    });

}

活动：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_tab_update,
            container,
            false);
    ButterKnife.bind(this, view);
    RelativeLayout = contentuserimportMod;
    RelativeLayout1 = delResMod;
    moduleID = Objects.requireNonNull(getActivity()).getIntent().getStringExtra("id");
    moduleCode =Objects.requireNonNull(getActivity()).getIntent().getStringExtra("code");
    moduleName =Objects.requireNonNull(getActivity()).getIntent().getStringExtra("desc");
    Realm.init(Objects.requireNonNull(getContext()));
    RealmConfiguration defaultConfig = new RealmConfiguration.Builder()
            .schemaVersion(0)
            .build();

    realm=Realm.getInstance(defaultConfig);
    helper = new RealmHelper(realm);
    init();
    getAssessList();
    return view;
}
private void init(){
    linearLayoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.HORIZONTAL, false);
    AssList.setLayoutManager(linearLayoutManager);
    textView1.setText("Assessments - "+moduleName);
    List<AssessmentType> list = helper.retrieveAT();
    List<String> listString = new ArrayList<>();
    for(AssessmentType a : list) {
        listString.add(a.getDesc());
    }
    adapter = new ArrayAdapter<>(Objects.requireNonNull(getContext()), android.R.layout.simple_spinner_dropdown_item, listString);
    adapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item);
    spinnerOffline.setAdapter(adapter);
}
private void getAssessList(){
    RealmHelper helper=new RealmHelper(realm);
    FAssessmentList =helper.retrieveAF(moduleID);
    AssessTabUpdateAdapter adapter = new AssessTabUpdateAdapter(getContext(), FAssessmentList);
    AssList.setAdapter(adapter);
    adapter.notifyDataSetChanged();
    AssList.setAdapter(adapter);
}    

}

我希望删除立即显示，或者只是在删除发生时像在片段上重新加载一样调用，以便从视图中删除已删除的项目。
