Android 如何将日期从适配器更新到recyclerView？

当我发送新数据或更新信息时，如何更改我的回收视图

我使用了一个

dapter.notifyDataSetChanged（），但它不工作

我尝试了更多的方法，但这一切都不能改变我的回收者的看法

在我的代码中

 recyclerView =  view.findViewById(R.id.recyclerCoin);
        recyclerView.setHasFixedSize(true);
        layoutManager = new LinearLayoutManager(getActivity());
        recyclerView.setLayoutManager(layoutManager);
        listCoinDiamondModel = new ArrayList<>();
        requestQueue = Volley.newRequestQueue(getActivity());
        getData();
        adapter = new CoinAdapter(listCoinDiamondModel, getActivity());
        recyclerView.setAdapter(adapter);

private void sendGift(String postUserID) {
        final String postUserIDD = postUserID;
        final String GiftAmount = this.GiftAmount.getText().toString().trim();
        final String flag = "1";
        StringRequest stringRequest = new StringRequest(Request.Method.POST, URL_GIFTCOIN,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        try {
                            JSONObject jsonObject = new JSONObject(response);
                            String success = jsonObject.getString("success");
                            if (success.equals("1")){
                                adapter.notifyDataSetChanged();
                            }

                        } catch (JSONException e) {

你能告诉我怎么办吗
