Question

我正在使用返回JSON的REST Web服务。但是JSON对象值是

＆＃34; [12]＆＃34;

当我打印时。该值必须仅为12，而不是"[]"

我的代码错了吗？我的代码：

 HttpClient httpClient = new DefaultHttpClient();
                HttpPost post = new HttpPost("http://applocalize.com.br/rest/rest.php");

                try {
                    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
                    nameValuePairs.add(new BasicNameValuePair("pg","categorias"));
                    nameValuePairs.add(new BasicNameValuePair("serv","buscar"));
                    nameValuePairs.add(new BasicNameValuePair("dt_atualizacao","0"));
                    try{
                        post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                    }catch (UnsupportedEncodingException e){

                    }

                    HttpResponse resp = httpClient.execute(post);
                    String respStr = EntityUtils.toString(resp.getEntity());

                    if (resp.getStatusLine().getStatusCode() == 200)
                    {
                        System.out.println(respStr);
                        JSONArray temp1 = new JSONArray(respStr);
                        for (int i=0; i < temp1.length(); i++) {
                            JSONObject obj = temp1.getJSONObject(i);
                            System.out.println(obj.getString("id"));
                        }


                    }
                    System.out.println("OKAY!");
                } catch (ClientProtocolException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (JSONException e) {
                    e.printStackTrace();
                }

当我打印id

时，我的logcat

02-20 13:45:32.560  31135-31135/com.localizeapp I/System.out﹕ ["52"]
02-20 13:45:32.560  31135-31135/com.localizeapp I/System.out﹕ ["53"]
02-20 13:45:32.560  31135-31135/com.localizeapp I/System.out﹕ ["54"]

编辑：

respStr：

02-20 13：45：32.210 31135-31135 / com.allapps.localizeapp I / System.out:[ {＆＃34; id＆＃34;：[＆＃34; 51＆＃34;]，＆＃ 34; titulo＆＃34;：[＆＃34; Chaveiro＆＃34;]，＆＃34; icone＆＃34;：[＆＃34;这里的基地64 ......太长了＆＃34;] < / p>

问题是您的网络服务正在将值返回为JSONArray。您可以更改Web服务以发送数据

"id":"51"

或者你可以替换

System.out.println(obj.getString("id"));

与

System.out.println(obj.getJSONArray("id").get(0));

getJSONObject返回错误的值
