在通知内显示API数据

Question

我有一项服务API，用于检索数据，并且我设法获取了数据，但是它仍然是API格式。 我想在发出的通知中显示API数据，我需要解决此问题的方法...

    public class ReminderBoardcast extends BroadcastReceiver {
    InterfaceApi mApiService;
    String username;
    final String usr = "nanda";
    List<NotifModel> arraymodel = new ArrayList<>();
    Notif_Get adapter;
    int total1;

    public void onReceive(Context context, Intent intent){
        username = usr;
        daftar();
    }

    private void daftar() {
        new dapatdata().execute();
    }

    private  class dapatdata extends AsyncTask<Void,Void,Void> {
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }

        @Override
        protected Void doInBackground(Void... voids) {
            mApiService = UtilsApi.getApiSerivce();
            mApiService.getkelompok(username)
                    .enqueue(new Callback<List<NotifModel>>() {
                        @Override
                        public void onResponse(Call<List<NotifModel>> call, Response<List<NotifModel>> response) {
                            if (response.isSuccessful()){
                                try {
                                    if (response == null){
                                        System.out.println("DATA NULL");
                                    }else {
                                        System.out.println("DATA ADA");
                                        List<NotifModel> models = response.body();
                                        arraymodel.addAll(models);
                                        adapter = new Notif_Get(arraymodel, ReminderBoardcast.this);
                                        adapter.notifyDataSetChanged();
                                        System.out.println("TOTAL DATA: "+adapter.getItemCount());
                                        int total = adapter.getItemCount();


                                    }
                                }catch (Exception e){
                                    System.out.println("EROR");
                                }
                            }else {
                                System.out.println("TIDAK SUKSES");
                            }
                        }

                        @Override
                        public void onFailure(Call<List<NotifModel>> call, Throwable t) {

                        }
                    });

            return null;
        }

        public void jalankan(Context context, Intent intent){
            NotificationCompat.Builder builder = new NotificationCompat.Builder(context, "notifyLemubit")
                    .setSmallIcon(R.drawable.ic_launcher_background)
                    .setContentTitle("INFO CUSTOMER")
                    .setContentText("Halo, this is notification")
                    .setPriority(NotificationCompat.PRIORITY_DEFAULT);

            NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(context);
            notificationManagerCompat.notify(200, builder.build());

        }

    }
}

在jalankan()中，它是用于通知的代码，而在daftar()中，它是用于获取API的代码
