Question

我想从WorldWeatherOnline解析简单的天气数据但是当我发出请求并用JSON解析它时，我的列表中没有响应这是来自WWO的JSON数据：

                "weatherIconUrl": [

                ],

                "winddirection": "NNE",
                "windspeedKmph": "15",
                "windspeedMiles": "9"
            }
        ]
    }
}

这是我解析JSON的代码

if (status == 200) {
    HttpEntity entity = response.getEntity();
    String data = EntityUtils.toString(entity);

    JSONObject jsono = new JSONObject(data);
    JSONArray jarray = jsono.getJSONArray("current_condition");

    for (int i = 0; i < jarray.length(); i++) {
        JSONObject object = jarray.getJSONObject(i);

        Weather weather = new Weather();
        weather.cloudcover(object.getString("cloudcover"));
        weather.sethumidity(object.getString("humidity"));
        actor.setweatherDesc(object.getString("weatherDesc"));
        weatherList.add(weather);
    }
}

请有人提出如何解析这4个参数的想法。提前致谢

当前条件位于数据json对象内部，您不会进入该对象。试试这个

                    JSONObject jsono = new JSONObject(data);
                    JSONObject weatherData = jsono.getJSONObject("data"); 
                    JSONArray currentData = weatherData.getJSONArray("current_condition");

Android中解析JSON数组数组
