【问题描述】：

我正在开发一个基于 REST API 远程数据的 android 应用程序，其中我制作了一个带有“接受”和“拒绝”两个按钮的ListView。

当用户选择“接受”按钮时，JSON 属性的某些部分必须更改为 true，如果他们选择“拒绝”按钮，JSON 属性的某些部分必须更改为false 和 @POST 它。

我该怎么做？

到目前为止我做了什么：

我的主要活动：

public class ViewRefundRequest extends AppCompatActivity

    ProgressBar progressBarVRR;
    private ListView viewRefundRequestListView;
    RelativeLayout vrrMainLayout;

    ApiService serviceVRR;
    TokenManager tokenManagerVrr;

    Call<List<ViewRefundRequestModel>> callViewRefundRequestData;

    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_view_refund_request);

        tokenManagerVrr = TokenManager.getInstance(getSharedPreferences("prefs", MODE_PRIVATE));
        serviceVRR = RetrofitBuilder.createServiceWithAuth(ApiService.class, tokenManagerVrr);

        progressBarVRR = (ProgressBar) findViewById(R.id.viewRefundRequestProgressBar);
        viewRefundRequestListView = (ListView) findViewById(R.id.viewRefundRequestListView);

        //Rest Api call
        allViewRefundRequestData();
    

    private void updateUI(List<ViewRefundRequestModel> VrrModel) 

        AdminViewRefundRequestAdapter adapterVrr = new AdminViewRefundRequestAdapter(VrrModel, this);
        viewRefundRequestListView.setAdapter(adapterVrr);

    

    private void allViewRefundRequestData() 
        progressBarVRR.setVisibility(View.VISIBLE);
        callViewRefundRequestData = serviceVRR.getAllViewRefundRequest();
        callViewRefundRequestData.enqueue(new Callback<List<ViewRefundRequestModel>>() 
            @Override
            public void onResponse(@NotNull Call<List<ViewRefundRequestModel>> call, @NotNull Response<List<ViewRefundRequestModel>> response) 
                progressBarVRR.setVisibility(View.GONE);

                if (response.isSuccessful() && response.body() != null)

                    updateUI(response.body());

                else 

                    if (response.code() == 401) 
                        startActivity(new Intent(ViewRefundRequest.this, LoginActivity.class));
                        finish();
                        tokenManagerVrr.deleteToken();
                        Toast.makeText(ViewRefundRequest.this, "User session expired, Login again", Toast.LENGTH_LONG).show();
                    
                
            

            @Override
            public void onFailure(@NotNull Call<List<ViewRefundRequestModel>> call, @NotNull Throwable t) 
                progressBarVRR.setVisibility(View.GONE);

                Snackbar snackbar = Snackbar.make(findViewById(android.R.id.content), "Network Status: " + t.getMessage(), Snackbar.LENGTH_LONG);
                View snackbarView = snackbar.getView();
                snackbarView.setBackgroundColor(Color.parseColor("#f5003d"));
                TextView tv = (TextView) snackbarView.findViewById(R.id.snackbar_text);
                tv.setTextColor(Color.WHITE);
                snackbar.show();
            
        );
    

    @Override
    protected void onDestroy() 
        super.onDestroy();

        if (callViewRefundRequestData != null) 
            callViewRefundRequestData.cancel();
            callViewRefundRequestData = null;
        
    

我的适配器类：

public class AdminViewRefundRequestAdapter extends BaseAdapter 

private List<ViewRefundRequestModel> viewRefundRequestModels;
    private Context context;

    public AdminViewRefundRequestAdapter(List<ViewRefundRequestModel> viewRefundRequestModels, Context context) 
        this.viewRefundRequestModels = viewRefundRequestModels;
        this.context = context;
    

    @Override
    public int getCount() 
        return viewRefundRequestModels.size();
    

    @Override
    public Object getItem(int position)       

        return viewRefundRequestModels.get(position);
    

    @Override
    public long getItemId(int pos) 
        return pos;
    

    @Override
    public View getView(int position, View view, ViewGroup viewGroup) 

        if (view == null)
            view = LayoutInflater.from(context).inflate(R.layout.model_view_refund_reques, viewGroup, false);
        

        TextView patient_name = view.findViewById(R.id.patient_name_VRR_Model);
        TextView patient_id = view.findViewById(R.id.patient_id_VRR_Model);
        TextView item_name = view.findViewById(R.id.item_name_VRR_Model);
        TextView category = view.findViewById(R.id.category_VRR_Model);
        TextView quantity = view.findViewById(R.id.quantity_VRR_Model);
        TextView amount = view.findViewById(R.id.amount_VRR_Model);
        TextView discount = view.findViewById(R.id.discount_VRR_Model);
        TextView amount_after_discount = view.findViewById(R.id.amount_after_discount_VRR_Model);
        TextView refund_note = view.findViewById(R.id.refund_note_VRR_Model);

        Button make_decisionBtn_Yes = view.findViewById(R.id.make_decisionBtn01_VRR_Model);
        Button make_decisionBtn_No = view.findViewById(R.id.make_decisionBtn02_VRR_Model);

        make_decisionBtn_Yes.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View view) 
                //accept the request and make the certain portion of the Json Object property to true
            
        );

        make_decisionBtn_No.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View view) 
                //accept the request and make the certain portion of the Json Object property to false
            
        );

        final ViewRefundRequestModel thisModelResponse = viewRefundRequestModels.get(position);

        Patient patient = thisModelResponse.getPatient();
        String patientName= patient.getFirstName()+" "+patient.getLastName();

        Item item =thisModelResponse.getItem();
        String itemName= item.getName();

        ItemCategory itemCategory = item.getItemCategory();
        String itemCategoryName = itemCategory.getName();

        patient_name.setText(patientName);
        patient_id.setText(Integer.toString(thisModelResponse.getPatientID()));
        item_name.setText(itemName);
        category.setText(itemCategoryName);
        quantity.setText(Integer.toString(thisModelResponse.getServiceQuantity()));
        amount.setText(Double.toString(thisModelResponse.getServiceActualPrice()));
        discount.setText(Double.toString(thisModelResponse.getDiscount()));
        amount_after_discount.setText(Double.toString(thisModelResponse.getServiceListPrice()));
        refund_note.setText(thisModelResponse.getRefundNote());

        return view;
    

必须更改 JSON 文件的这一部分：

【参考方案1】：

首先你必须改变你的实现并使用RecyclerView。此外， ViewRefundRequestModel 是一个对象，因此您将其映射到List，如我所见。您可以根据按钮更改字段RefundStatus 的状态。后者必须在RecyclerView.Adapter 的onBindViewHolder 内完成。请搜索RecyclerView的实现。总而言之，我假设您可以将您的列表与帖子一起发送。

【讨论】：

你可以使用retrofit

是的，我确实在使用改造，但我的问题是如何修改我获取的数据并将其从适配器以特定用户 ID 为目标发送或发回？请看图片
