JSON字符串數組到JSON數組

我有一個字符串，如下面，我從網絡服務JSON字符串數組到JSON數組

收到現在，我想將其更改爲jArray（GSON libraray）。變量itemsJsonString包含通過Web服務接收到的字符串。

JsonArray jArray = new JsonArray(); 
JsonPrimitive element = new JsonPrimitive(gson.toJson(itemsJsonString)); 
jArray.add(element);

當我運行上面的代碼時，我得到Illegalstateexception不是json對象錯誤。

這是一個堆棧跟蹤。提供與strace的

剩下的就是充滿了JSON字符串

的可能有人能幫助我在這個問題上。我無法弄清楚我自己過去三天:(

爲什麼你不使用org.json內置android –

我正在使用Azure移動服務。 GSON與它密切配合。 – user3296042

Gson基本上是設計來轉換POJO類中的json響應。否則org.json是好的 –

做這樣

您可以輕鬆地解析JSON使用org.json

try { 
      JSONArray jArray = new JSONArray(responseString); 
      int size= jArray.length(); 
      for (int i = 0; i < size; i++) { 
       JSONObject item= jArray.getJSONObject(i); 
       System.out.println("id : " + item.getString("id")); 
       System.out.println("itemname : " + item.getString("itemname")); 
       System.out.println("itemdescription : " + item.getString("itemdescription")); 

        // ........ so on 

      } 
     } catch (Exception e) { 
     }

您可以使用此方法

public static ArrayList parseJSON(String url, int method,List<NameValuePair> params, Class classType) { 

    ArrayList list = new ArrayList();

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() 
      .permitAll().build(); 
    StrictMode.setThreadPolicy(policy); 
    String respo = ""; 
    try { 
     DefaultHttpClient httpClient = new DefaultHttpClient(); 

     HttpResponse httpResponse = null; 

     if (method == POST) { 

      HttpPost httpPost = new HttpPost(url); 

      // adding post params 
      if (params != null) { 
       httpPost.setEntity(new UrlEncodedFormEntity(params)); 
      } 

      httpResponse = httpClient.execute(httpPost); 

     } else if (method == GET) { 
      // appending params to url 
      if (params != null) { 
       String paramString = URLEncodedUtils 
         .format(params, "utf-8"); 
       url += "?" + paramString; 
      } 
      HttpGet httpGet = new HttpGet(url); 

      httpResponse = httpClient.execute(httpGet); 

     } 

     StatusLine statusLine = httpResponse.getStatusLine(); 

     int statuscode = statusLine.getStatusCode(); 
     Log.v("Pre School App", "Response code = " + statuscode); 

     if (statuscode == 200) { 
      HttpEntity entity = httpResponse.getEntity(); 
      respo = EntityUtils.toString(entity); 
      Log.e("Pre School App test ", "Status code = " + respo); 
     } else { 
      Log.e("Pre School App test ", "Status code = " + respo); 
     } 

     // HttpEntity entity = httpResponse.getEntity(); 
     // respo = EntityUtils.toString(entity); 

    } catch (Exception e) { 
     // Toast.makeText(myContext, "Error !" + e, 
     // Toast.LENGTH_LONG).show(); 
     e.printStackTrace(); 
    } 

    if (classType != null) { 
     try { 
      JSONArray jArray = new JSONArray(respo); 
      for (int i = 0; i < jArray.length(); i++) { 
       JSONObject json = jArray.getJSONObject(i); 
       Gson gson = new Gson(); 
       list.add(gson.fromJson(json.toString(), classType)); 

      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } else { 
     return null; 
    } 
    return list; 
}

只發布您的代碼的相關部分。 –

嘗試把.replaceAll("\\\","")在你的代碼只要你代碼解析您的JSON。它的選擇。 :)）
