Question

我正在尝试将数据从JSONObject作为数组返回，以便我可以遍历它们。关于udacity的android开发培训，但培训中使用的JSON结构与我使用的不同。下面是我的班级

  private String[] getWeatherDataFromJson(String forecastJsonStr)
            throws JSONException {

        // These are the names of the JSON objects that need to be extracted.
        final String OWM_LIST = "rules";
        final String OWM_DESCRIPTION = "game_rules_content";

        JSONObject forecastJson = new JSONObject(forecastJsonStr);
        JSONArray weatherArray = forecastJson.getJSONArray(OWM_LIST);
        Log.v(LOG_TAG, "success: " + forecastJson.getInt("success"));

       //I guess my problem is starts here
       String[] resultStrs = new String[1];

        for(int i = 0; i < weatherArray.length(); i++) {

            String rule;
            // Get the JSON object representing the day
            JSONObject dayForecast = weatherArray.getJSONObject(i);
            rule = dayForecast.getString(OWM_DESCRIPTION);
            Log.v(LOG_TAG, "sammy: " + rule);

             // how do i return my json data as array for i loop through the array with for
            resultStrs[0] = rule;

        }

        for (String s : resultStrs) {
            Log.v(LOG_TAG, "Forecast entry: " + s);
        }
        return resultStrs;

    }

Answer 1

你可以发布链接获取json或你的json。如果可以，你应该尝试使用gson库来解析json，例如：gson example

Answer 2

你应该编写类似这样的代码。

 resultStrs[i] = rule;

这将解决您的问题。欢呼声。
