JSONObject给我错误

-1

我有一个json从服务器返回给我。我想迭代，但其gving我的错误在这条线的红色.getJSONObject（I）JSONObject给我错误

JSONObject obj = jsonHospitals.getJSONObject(i);

误差强调，给我两个选择 1变化optJSONObject（...） 2 - 将'i'的类型更改为'字符串'

我能做些什么来使用JSONObject并遍历json。我是新来的机器人，所以请忍受我的家伙！下面是一些代码

String responseData = new String(charArray); 

        JSONObject jsonHospitals = new JSONObject(responseData); 

        for(int i = 0; i< jsonHospitals.length(); i++){ 
         JSONObject obj = jsonHospitals.getJSONObject(i); 
         JSONObject hospital_obj = obj.getJSONObject("Hospital"); 
         String hospital_name = hospital_obj.getString("hospital_name"); 
         Log.v(TAG, hospital_name); 
        }

感谢 UPDATE * OK受审新的东西，所有张贴现在这里 *

我想这个代码

try { 

       URL hospitalFeedUrl = new URL("siteresponseaddress"); 
       HttpURLConnection connection = (HttpURLConnection)hospitalFeedUrl.openConnection(); 
       connection.connect(); 
       responseCode = connection.getResponseCode(); 
       if(responseCode == HttpURLConnection.HTTP_OK){ 
        InputStream inputStream = connection.getInputStream(); 
        Reader reader = new InputStreamReader(inputStream); 
        int contentLenght = connection.getContentLength(); 
        char[] charArray = new char[contentLenght]; 
        reader.read(charArray); 
        String responseData = new String(charArray); 

        JSONArray jsonHospitals = new JSONArray(responseData); 

        for(int i = 0; i< jsonHospitals.length(); i++){ 
         JSONObject obj = jsonHospitals.getJSONObject(i); 
         JSONObject hospital_obj = obj.getJSONObject("Hospital"); 
         String hospital_name = hospital_obj.getString("hospital_name"); 
         Log.v(TAG, hospital_name); 
        } 
        Log.v(TAG, responseData); 
       } 
       else { 
        Log.i(TAG, "Unsccessful HHTP Response Code "+ responseCode); 
       } 
       Log.i(TAG, "Code " + responseCode); 
      } 
      catch (MalformedURLException e) { 
       Log.e(TAG, "exception caught: ", e);  
      } 
      catch (IOException e) { 
       Log.e(TAG, "exception IO caught: ", e); 
      } 
      catch(Exception e){ 
       Log.e(TAG, "General exception", e); 
      }

NOW那给我在LOG LOG

请发布您试图解析的JSON样本。它不清楚，如果你实际上有一个JSON数组或对象。 –

@BrianRoach我猜它链接到他以前的问题@ http://stackoverflow.com/questions/21846806/how-to-parse-this-response-using-jsonobject – Raghunandan

而且，那里的答案告诉op *完全*如何解析它。 –

的一部分没有getJSONObject这需要INT作为PARAM。

http://developer.android.com/reference/org/json/JSONObject.html

public JSONObject getJSONObject (String name) 

Added in API level 1 
Returns the value mapped by name if it exists and is a JSONObject. 

Throws 
JSONException if the mapping doesn't exist or is not a JSONObject.

因此，错误。您需要发布您的JSON用于进一步的帮助

您的JSON似乎类似于我已经回答了@

how to parse this response using JSONObject

编辑一个在你前面的问题：

try 
    { 
    HttpClient httpclient = new DefaultHttpClient(); 
    httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); 
    HttpGet request = new HttpGet("your url "); 
    HttpResponse response = httpclient.execute(request); 
    HttpEntity resEntity = response.getEntity(); 
    String _response=EntityUtils.toString(resEntity); 
     JSONArray jr = new JSONArray(_response); 
     for(int i=0;i<jr.length();i++) 
     { 
     JSONObject jb = (JSONObject)jr.getJSONObject(i); 
     JSONObject jb1 =(JSONObject) jb.getJSONObject("Hospital"); 
     String name = jb1.getString("hospital_name"); 
     Log.i("name....",name); 
     } 
    }catch(Exception e) 
    { 
     e.printStackTrace();

@BrianRoach也许。不在这里http://developer.android.com/reference/org/json/JSONObject.html#getJSONObject(java.lang.String）。 – Raghunandan

在编辑之前，我实际上是在误读你的答案。 –

请看我的updat。我已经添加了一个详细的信息，CatLog正在说什么等 – Autolycus

变化：

JSONObject obj = jsonHospitals.getJSONObject(i);

发送至：

JSONObject obj = jsonHospitals.getJSONObject(String.valueof(i));

的原因是因为该功能getJSONObject需要一个字符串作为它的参数 - Link to API Documentation

您试图遍历一个JSONArray 改变这一行：

的JSONObject jsonHospitals =新的JSONObject （responseData）;

此

JSONAray jsonHospitals =新JSONAray（responseData）;

如果它仍然不起作用，你能否提供你的JSON resopnse。

请参阅更新谢谢 – Autolycus

如果输入JSON的类型是JSON阵列，你应该把它看作（见doc）：

JSONArray array = new JSONArray(responseData);

然后你就可以遍历它，使用：

for(int i = 0; i< array.length(); i++) { 
    array.getJSONObject(i); 
}

Hi Autolycus, 
      I think you have to parse responseData as JSONArray like below 

      **JSONArray jsonHospitals = new JSONArray(responseData);** 

      for(int i = 0; i< jsonHospitals.length(); i++){ 
        JSONObject obj = jsonHospitals.getJSONObject(i); 
        JSONObject hospital_obj = obj.getJSONObject("Hospital"); 
        String hospital_name = hospital_obj.getString("hospital_name"); 
        Log.v(TAG, hospital_name); 
       } 

     Hope it will work for you :)
