android - 如何为multiautocompletetextview预定义值在android中不起作用

Question

嗨，我有两种情况一种是具有预定义值的另一种是 multiautocompletetextview。

第一个场景：

从服务器我正在检查 id。如果数据库中存在 id，则希望显示预定义的值以及 multiautocompletetextview。

如果 id 不匹配，则第二种情况想要显示 multiautocompletetextview 列表。任何人都可以帮助如何将 predifed 值设置为 multiautocompletetextview。

爪哇：

String isbookingexist=getArguments().getString("isBookingexist");
        if(isbookingexist.equals("true")){
            FetchPatientMedicalDetails();
            GetPreExistingConditionList();
        }

预定义值：

FetchPatientMedicalDetails(){
pre_condition=medicalDataList.getExistingCondtn();
}

完整列表：

 private void GetPreExistingConditionList() {

            final APIService service = RetroClass.getRetrofitInstance().create(APIService.class);
            Call<MedicalInformationModel> call = service.GetMedicalInformationDropDownList();
            Log.wtf("URL Called", call.request().url() + "");
            call.enqueue(new Callback<MedicalInformationModel>() {
                @Override
                public void onResponse(Call<MedicalInformationModel> call, Response<MedicalInformationModel> response) {

                    Log.e("response", new Gson().toJson(response.body()));
                    if (response.isSuccessful()) {
                        Log.e("response", new Gson().toJson(response.body()));
                        MedicalInformationModel medicalInformationModel = response.body();
                        final ArrayList<PreExistingCondition_DropdownList> preExistingCondition = medicalInformationModel.getPreExistingCondition();
                        final ArrayList<Allergies_DropdownList> allergies_dropdown=medicalInformationModel.getAllergies();
                        final ArrayList<Symptoms_DropdownList> symptoms_dropdown=medicalInformationModel.getSymptoms();
                        final ArrayList<Complaints_DropdownList> complaints_dropdown=medicalInformationModel.getComplaints();

                        //Pre Existing Conditions Dropdownlist
                        for (PreExistingCondition_DropdownList preExistingCondition_dropdownList : preExistingCondition) {
                            String Id = preExistingCondition_dropdownList.getId();
                            String Conditions=preExistingCondition_dropdownList.getCondition();
                            PreExistingCondition_DropdownList preExistingCondition_dropdownList1 = new PreExistingCondition_DropdownList(Id,Conditions);
                            preExistingCondition_dropdownLists.add(preExistingCondition_dropdownList1);
                            Pre_Conditions.add(Conditions);

                            pre_existing_condition.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                                @Override
                                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                                    PreExistingCondition_DropdownList preExistingCondition_dropdownList1=preExistingCondition_dropdownLists.get(position);
                                    preconid=preExistingCondition_dropdownList1.getId();
                                    precontname=preExistingCondition_dropdownList1.getCondition();
                                }
                            });
                        }
                    }
                }
                @Override
                public void onFailure(Call<MedicalInformationModel> call, Throwable t) {
                    Log.d("error", t.getMessage());
                }
            });
        }
