我正在使用org.json.JSONException:我的json数组中没有item的值

问题描述 投票:0回答:1

即使我在json数组中有“ feels_like”,您也可以在日志信息中看到错误,但表明它不存在

CODE:

    protected void onPostExecute(String s) {
        super.onPostExecute(s);
        try {
            JSONObject jsonObject = new JSONObject(s);
            String weather = jsonObject.getString("weather");
            String temperature = jsonObject.getString("main");
            String ans = weather + temperature;
            Log.i("ans",ans);

            JSONArray arr = new JSONArray(ans);
            for (int i=0;i<arr.length();i++){
                JSONObject jsonpart = arr.getJSONObject(i);

                getweather.setText(jsonpart.getString("feels_like") + "\n" + jsonpart.getString("description"));

            }

        }catch (Exception e){
            e.printStackTrace();
        }
    }

错误:

根据堆栈跟踪,看起来JSON中没有键(feels_like),或者尝试从错误的JSONObject访问。如果您发布JSON结构,可能有助于更好地理解。
