android - 如何在 Android 上使用 Retrofit2 从微调器中检索 2 个值

Question

我有代码可以从 JSON 调用数据至 Spinner , 并在 Toast 中显示数据当数据被选中时，但我想从JSON中获取第二个数据，例如类型我选择 "PERMIT" 它会在 Toast 中显示代码 "100" (这将是我保存到 TextView )

JSON:

{
    "total_results": "3",
    "value": 1,
    "status": true,
    "result": [
        {
            "GroupCode": "I",
            "Code": "100",
            "Type": "PERMIT",
            "MaxTotalReq": "0",
            "MinRequest": null
        }
    ]
}

到目前为止，我已经尝试显示来自 JSON 的“PERMIT”结果

    leaveType.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            String selected = parent.getItemAtPosition(position).toString();
            Toast.makeText(context, "Choose " + selected, Toast.LENGTH_SHORT).show();
        }
        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });

private void initSpinnerType(){
        RetrofitInterface api = RetrofitClient.getClient().create(RetrofitInterface.class);
        Call<LeaveTypeResponse> call = api.getDataPermit();
        call.enqueue(new Callback<LeaveTypeResponse>() {
            @Override
            public void onResponse(Call<LeaveTypeResponse> call, Response<LeaveTypeResponse> response) {
                if (response.isSuccessful()) {
                    List<LeaveType> leaveTypeItems = response.body().getResult();
                    for (int i = 0; i < leaveTypeItems.size(); i++){
                        String Code = leaveTypeItems.get(i).getCode(); // I want to show this when Selected
                        String leaveType = leaveTypeItems.get(i).getType();
                        listSpinner.add(leaveType);
                    }
                    listSpinner.add(0, "- SELECT TYPE -");

                    adapter = new ArrayAdapter<>(context, android.R.layout.simple_spinner_item, listSpinner);
                    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                    leaveType.setAdapter(adapter);

                } else {
                    Toast.makeText(context, "FAILED", Toast.LENGTH_SHORT).show();
                }
            }
            @Override
            public void onFailure(Call<LeaveTypeResponse> call, Throwable t) {
                t.printStackTrace();
                Toast.makeText(context, "CAN'T CONNECT", Toast.LENGTH_SHORT).show();
            }
        });
    }

如何设置变量 Code至 OnSelectedItem

[编辑]

String selected = parent.getItemAtPosition(position).toString();

此代码显示值 "PERMIT" 的 leaveType 变量的值我需要这个选择显示代码中的变量值 "100"

                    String Code = leaveTypeItems.get(i).getCode(); // I want to show this when Selected
                    String leaveType = leaveTypeItems.get(i).getType();
                    listSpinner.add(leaveType);
                    // Add your code into an separate ArrayList
                    listCode.add(code);
                }
                listSpinner.add(0, "- SELECT TYPE -");

                adapter = new ArrayAdapter<>(context, android.R.layout.simple_spinner_item, listSpinner);
                adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                leaveType.setAdapter(adapter);

            } else {
                Toast.makeText(context, "FAILED", Toast.LENGTH_SHORT).show();
            }

        }
    });
}

你的听众:

leaveType.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        // position -1 because in listspinner we add an extra String at 0 index
        String selectedCode=listCode.get(--position);
        String selected = parent.getItemAtPosition(position).toString();
        Toast.makeText(context, "Choose " + selectedCode, Toast.LENGTH_SHORT).show();
    }
    @Override
    public void onNothingSelected(AdapterView<?> parent) {
