微调值不更新

Spinner value not update

这是我的 Country Spinner,在这里我获取国家 ID 并使用国家代码传入 ApiGetState 我正在获取州列表,在获取州列表后我想在 State Spinner 中设置它,我已经完成了所有操作但是如果我 select 国家第一次工作正常,但如果我改变国家,状态微调器不更新,我是否遗漏了这段代码中的某些内容?

country.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            scountry = parent.getItemAtPosition(position).toString();
            String cCode = scountry.substring(0, scountry.indexOf("-"));
            countryCode = Integer.parseInt(cCode);
            ApiGetStates(countryCode);
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

我在这里从服务器设置 StateSpinner 的值:-

public void onResponse(Call<StatesModel> call, Response<StatesModel> response) {
            if (response.isSuccessful()){
                StatesModel model = response.body();
                List<StatesModel.StatesModelDetail> list = model.getData();
                for (int i = 0; i < list.size(); i++){
                    stateData = list.get(i);
                    String stateName = stateData.getName();
                    String code = stateData.getId();
                    String finalname = code + "-" + stateName;
                    arrayList.add(finalname);
                    ArrayAdapter<String> adapter = new ArrayAdapter<>(getContext(), R.layout.simple_spinner_dropdown, arrayList);
                    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                    state.setAdapter(adapter);
                    adapter.notifyDataSetChanged();
                }

我做了这件事。只需清除“ApiGetStates(countryCode);”之前的数组列表并调用“adapter.notifyDataSetChanged();”根据 Sandeep Pareek,在“for 循环”之外。例如:-

arrayList.clear();
ApiGetStates(countryCode);
