Question

我已经调用了一个web服务作为响应，我得到了一个json字符串。我尝试了破坏字符串但我收到错误。我试过调试，我发现它正在捕获块中。

jsonObject = new JSONObject(result);
            if (jsonObject == null) {
                Toast.makeText(context, "nothing to show", Toast.LENGTH_LONG)
                        .show();
            }
            NewDataSet = jsonObject.getJSONObject("NewDataSet");
            Table = NewDataSet.getJSONObject("Table");
            sync = Table.getJSONArray("Table");
            for (int i = 0; i < sync.length(); i++) {
                JSONObject jobj = sync.getJSONObject(i);
                Event event = new Event();
                String Action_Flag = jobj.getString("Action_Flag");
                event.eventAddress = jobj.getString("Address");
                String Batch_ID = jobj.getString("Batch_ID");
                event.eventCity = jobj.getString("City");
                event.companyCode = jobj.getString("Company_Code");
                event.countryCode = jobj.getString("Country_Code");
                event.eventId = jobj.getString("Event_ID");
                event.eventname = jobj.getString("Event_Name");
                event.venue = jobj.getString("Event_Venue");
                event.iEventCode = jobj.getString("IEvent_Code");
                event.eventStatus = jobj.getString("IEvent_Status_Code");
                String Is_Synced = jobj.getString("Is_Synced");
                String ISponsor_Code = jobj.getString("ISponsor_Code");
                event.startDate = jobj.getString("Setup_Date_Time");
                event.sponsorName = jobj.getString("Sponsor_Name");
                event.state = jobj.getString("State_Code");
                event.endDate = jobj.getString("TearDownDateTime");
                String TearDownDateTime_Val = jobj
                        .getString("TearDownDateTime_Val");

                DatabaseHandler db = new DatabaseHandler(context);
                if (Action_Flag.equals("1")) {
                    long id = db.insertEvents(event);
                    Log.e("Insert value", String.valueOf(id));
                } else if (Action_Flag.equals("2")) {
                    long id = db.updateEvent(event);
                    Log.e("Update value", String.valueOf(id));
                } else {
                    int id = db.deleteEvent(event.eventId);
                    Log.e("delete value", String.valueOf(id));
                }
            }

        } catch (JSONException e) {

            e.printStackTrace();
        }

Answer 1

尝试以下代码： -

在获取表值时使用jsonobject

Table = NewDataSet.getJSONObject("Table");

但它是jsonarray所以如下所示

JSONArray table = NewDataSet.getJSONArray("Table");

注意： -

{}表示jsonobject

[]表示jsonarray

Json解析器无法在我的应用程序中工作
