我正在尝试以以下特定格式获取一个 json 文件。

{
   "business":[
      {
     "id":"13",
     "category":"Dinner",
     "subcategory":"",
     "name_eng":"dinner 1",
     "name_arab":"dinner 1",
     "mobile":"12345",
     "address":"not now",
     "logo":"1.gif",
     "contact":"Call",
     "open_time":"10 PM",
     "close_time":"8 PM"
     }
  ],
   "business_cat":[
  [
     "cat 1",
     {
        "name":"dish 1",
        "id":"7",
        "name_arab":"dish1",
        "desc_eng":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "desc_arab":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "price":"200 KD",
        "logo":"laptop.jpeg"
     },
     {
        "name":"dish 2",
        "id":"8",
        "name_arab":"dish 2",
        "desc_eng":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "desc_arab":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "price":"123789",
        "logo":"micky.jpg"
     },
     {
        "name":"dish3",
        "id":"13",
        "name_arab":"dish3",
        "desc_eng":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "desc_arab":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "price":"300 KD",
        "logo":"1.jpg"
     },
     {
        "name":"new dish",
        "id":"15",
        "name_arab":"new dish",
        "desc_eng":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "desc_arab":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "price":"213 KD",
        "logo":"12.jpg"
     }
   ],
   [
     "cat2",
     {
        "name":"dish3",
        "id":"14",
        "name_arab":"dish3",
        "desc_eng":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "desc_arab":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "price":"123 KD",
        "logo":"10.jpg"
     },
     {
        "name":"dish 4",
        "id":"16",
        "name_arab":"dish4",
        "desc_eng":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "desc_arab":"5 Chicken Legs\r\n5 Hamous\r\n5 Fires\r\n5 Pepsi",
        "price":"110 KD",
        "logo":"3.jpg"
        }
     ]
   ]
}

现在我如何访问“business”、“business_cat”和“business_cat”、“cat 1”和“cat 2”名称以及“cat 1”和“cat 2”中的所有对象。请这对我来说处理这样的json数据有点复杂，帮帮我。

尝试如下：

使用以下方法读取 JSON：

   public static String parseJSON(String p_url) {
    JSONObject jsonObject = null;
    String json = null;
    try {
        // Create a new HTTP Client
        DefaultHttpClient defaultClient = new DefaultHttpClient();
        // Setup the get request
        HttpGet httpGetRequest = new HttpGet(PeakAboo.EmailUrl + p_url);
        System.out.println("Request URL--->" + PeakAboo.EmailUrl + p_url);
        // Execute the request in the client
        HttpResponse httpResponse = defaultClient.execute(httpGetRequest);
        // Grab the response
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                httpResponse.getEntity().getContent(), "UTF-8"));
        json = reader.readLine();
        System.err.println("JSON Response--->" + json);
        // Instantiate a JSON object from the request response
        jsonObject = new JSONObject(json);
    } catch (Exception e) {
        // In your production code handle any errors and catch the
        // individual exceptions
        e.printStackTrace();
    }
    return json;
}

之后解析如下：

      try{
          String response=parseJSON(URL);
        JSONObject responseJson = new JSONObject(response);
        JSONArray m_bus_cat=responseJson.getJSONArray("business_cat");
            for(int i=0; i<m_bus_cat.length(); i++){
                     JSONObject catJson = new JSONObject(i);
                      if(catJson .has("cat 1")){
                       JSONArray resultArr = resultInstanceJson.getJSONArray("cat 1");
                    for(int j=0; j<resultArr.length(); j++){
                        String Name = catJson .getString("name");
                       String id=catJson.getString("id");
                    }
                 }
                }
            }
        }
    }catch(Exception e){
        e.printStackTrace();
    }

尝试以下代码来解析响应数据

这jsonString是您从响应中获得的字符串。

try {
        JSONObject jsonObject=new JSONObject(jsonString);
        JSONArray business=jsonObject.getJSONArray("business");
        for(int i=0;i<business.length();i++){
            JSONObject businessObject=business.getJSONObject(i);
            //you can store in array or arraylist
            String id=businessObject.getString("id");
            String category=businessObject.getString("category");
            // and so on
        }

        JSONArray businessCat=jsonObject.getJSONArray("business_cat");
        for(int i=0;i<businessCat.length();i++){
            JSONArray businessCatInner=businessCat.getJSONArray(i);
            String cat=businessCatInner.getString(0);

            for(int j=0;j<businessCatInner.length();j++){
                JSONObject businessInnerObject=businessCatInner.getJSONObject(i);
                //you can store in array or arraylist
                String name=businessInnerObject.getString("name");
                String name_arab=businessInnerObject.getString("name_arab");
                // and so on    
            }


        }
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
