Question

我正在解析以下json响应但是在解析时存在一些问题，我尝试的代码没有解析，我没有得到任何异常或响应。

我申请解析它的代码是：

    ArrayList<Model_BarcodeDetail> DownloadBarcode(String api_token) {
            ArrayList<Model_BarcodeDetail> barcodeList = new ArrayList<Model_BarcodeDetail>();
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost postRequest = new HttpPost(Utility.BASE_URL
                    + "?q=webservice/barcode_list&token=" + api_token +"&page="+"1"
                    + "&return=json");
            String url = Utility.BASE_URL
                    + "?q=webservice/barcode_list&token=" + api_token +"&page="+"1"
                    + "&return=json";
            System.out.println("======url::"+url);
            String result = "";
            ArrayList<Model_BarcodeDetail> group_list = null;
            ArrayList<Model_BarcodeList_Child> child_list = null;
            try {
                group_list = new ArrayList<Model_BarcodeDetail>();

                ResponseHandler<String> responseHandler = new BasicResponseHandler();
                result = httpClient.execute(postRequest, responseHandler);

                JSONObject root = new JSONObject(result);
                JSONObject obj = root.getJSONObject("");
                System.out.println("====objjjj: "+obj.toString());
                JSONArray arraylist=obj.names();


                for (int i = 0; i < arraylist.length(); i++) {
                    child_list = new ArrayList<Model_BarcodeList_Child>();
                    JSONObject jsonObj = arraylist.getJSONObject(i);
                    System.out.println("---json" + jsonObj);
                    Model_BarcodeDetail data = new Model_BarcodeDetail();
                    data.setReference((jsonObj.getString("ref")));
                    System.out.println("======refinprsing--"+data.getReference());
//                  data.setName((jsonObj.getString("name")));

//                  data.setTotal(data.getPrice().trim());
//                  data.setFixedTotal(data.getPrice().trim());
                    JSONArray obj2 = jsonObj.getJSONArray("barcodes");

                    for (int j = 0; j < obj2.length(); j++) {
                        JSONObject json = obj2.getJSONObject(j);
                        System.out.println("---json" + json);
                        Model_BarcodeList_Child data2 = new Model_BarcodeList_Child();
                        data2.setBarcode((json.getString("barcode")));
                        System.out.println("=======barcodeinparsing: "+data2.getBarcode());
                        data2.setColor((json.getString("color")));
                        data2.setSize((json.getString("size")));
                        data2.setPrice(json.getString("price"));
                        data2.setStock(json.getString("stock"));
                        data2.setAlis_code(json.getString("alias_code"));
                        child_list.add(data2);
                    }

                    data.setChildItems(child_list);
                    group_list.add(data);
                }
                for (int k = 0; k < group_list.size(); k++) {
                    System.out.println("-----==data itemref "
                            + group_list.get(k).getReference());
                    for (int y = 0; y < group_list.get(k).getChildItems().size(); y++) {
                        System.out.println("-----====data color "
                                + group_list.get(k).getChildItems().get(y)
                                        .getColor());

                    }
                }
            } catch (Exception e) {
                Log.i("Exception in DownloadBarcodechanges method: ", e.getMessage());
                return null;
            }
            return group_list;

        }

这是json：

Answer 1

基于json提供的更改：

JSONObject root = new JSONObject(result);
JSONObject obj = root.getJSONObject("");
System.out.println("====objjjj: "+obj.toString());
JSONArray arraylist=obj.names();

对此：

     JSONObject root = new JSONObject(result);
     JSONArray arraylist= root.names();

     for (int i = 0; i < arraylist.length(); i++) {
                    child_list = new ArrayList<Model_BarcodeList_Child>();
                    JSONObject jsonObj = root.getJSONObject(arrayList.getString(i));

我还会添加一个检查以查看该名称是否等于寻呼机，在这种情况下继续;

Answer 2

根据你的json Response做解析如下

JSONObject root = new JSONObject(result);
JSONArray array = root.getJSONArray("array");
String boolean = root.getString("boolean");
String null= root.getString("null");
String number= root.getString("number");
String string = root.getString("string");
JSONArray array_1 = root.getJSONArray("object");

首先检查你的结果是否为空？请查看日志。

Answer 3

这是解决方案

  JSONObject root = new JSONObject(result);

    if(root != null){
        Iterator iter = root.keys();

        while (iter.hasNext()){
            try {
                String key = (String) iter.next();

                JSONObject itemObject = root.getJSONObject(key);


            } catch (JSONException e) {

            }
        }
    }
