我试图深入到：forecast>txt\u forecast>{icon，icon\u url，title，fcttext}

我目前使用的是一个专用的JSONParser类，它不太好用。目前看起来是这样的：

package com.garciaericn.forecaster.data;

import android.util.Log;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import java.util.ArrayList;
import java.util.List;

/**

 */
public class JSONParser {

    public static final String TAG = "JSONParser.TAG";


    public static List<Weather> parseForecast(String jsonString) {
        Log.i(TAG, "parseForecast entered");

        List<Weather> weatherJSON = new ArrayList<Weather>();

        try {
            // Create JSON
            JSONObject data = new JSONObject(jsonString);

            // Create Array of weather objects
            JSONArray forecast = new JSONArray(data.getJSONArray("forecast").toString());
            JSONObject txtForecast = forecast.getJSONObject("txt_forecast");
            JSONObject simpeForecast = forecast.getJSONObject(Integer.parseInt("simpleforecast"));

            // Loop through recipesJSON for desired info
            for (int i = 0; i < txtForecast.length(); i++) {
                Log.i(TAG, "In for loop at index: " + i + " Object: " + forecast.getJSONObject(i));

                // This is where I was tring to obtain those fields
            }

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

        Log.i(TAG, "JSON array: " + weatherJSON);

        return weatherJSON;
    }
}

公共类JSONParser{
公共静态最终字符串TAG=“JSONParser.TAG”；
公共静态列表parseForecast（字符串jsonString）{
Log.i（标记“parseForecast entered”）；
List weatherJSON=new ArrayList（）；
试一试{
//创建JSON
JSONObject数据=新的JSONObject（jsonString）；
//创建天气对象数组
JSONArray forecast=newjsonarray（data.getJSONArray（“forecast”）.toString（））；
JSONObject txtForecast=forecast.getJSONObject（“txt_forecast”）；
JSONObject simpeForecast=forecast.getJSONObject（Integer.parseInt（“simpleforecast”）；
//循环搜索所需的信息
对于（int i=0；iJSON中的
数组以
[
开头，而对象以
{
开头。forecast
在JSON中不是数组，因此请更改此设置


JSONArray forecast = new JSONArray(data.getJSONArray("forecast").toString());


到


另外，
forecastday
是数组。因此相应地更改逻辑。
这里是我为自己工作的try/catch


try {
    // Create JSON
    JSONObject data = new JSONObject(jsonString);

    // Create Array of weather objects
    JSONObject forecast = new JSONObject(data.getJSONObject("forecast").toString());
    JSONObject txtForecast = new JSONObject(forecast.getJSONObject("txt_forecast").toString());
    JSONArray forecastDay = txtForecast.getJSONArray("forecastday");


    // TODO: Add more details to weather object with following info.
    //JSONObject simpleForecast = forecast.getJSONObject(forecast.getJSONObject("simpleforecast").toString());
    //JSONArray simpleForecastDay = simpleForecast.getJSONArray("forecastday");

    // Loop through recipesJSON for desired info
    for (int i = 0; i < forecastDay.length(); i++) {
        Log.i(TAG, "In for loop at index: " + i + " Object: " + forecastDay.getJSONObject(i));

        // Obtain Fields
        String dayOfWeek = forecastDay.getJSONObject(i).getString("title");
        String condition = forecastDay.getJSONObject(i).getString("icon");
        String forecastText = forecastDay.getJSONObject(i).getString("fcttext");
        String iconURL = forecastDay.getJSONObject(i).getString("icon_url");

        // Create instance of Weather
        Weather tempWeather = new Weather(dayOfWeek, condition, forecastText, iconURL);

        weatherJSON.add(tempWeather);
    }
} catch (JSONException e) {
    e.printStackTrace();
}



试试看{
//创建JSON
JSONObject数据=新的JSONObject（jsonString）；
//创建天气对象数组
JSONObject forecast=新的JSONObject（data.getJSONObject（“forecast”）.toString（）；
JSONObject txtForecast=新的JSONObject（forecast.getJSONObject（“txt_forecast”）.toString（）；
JSONArray forecastDay=txtfecast.getJSONArray（“forecastDay”）；
//TODO:使用以下信息向天气对象添加更多详细信息。
//JSONObject simpleForecast=forecast.getJSONObject（forecast.getJSONObject（“simpleForecast”）.toString（））；
//JSONArray simpleForecastDay=simpleForecast.getJSONArray（“forecastday”）；
//循环搜索所需的信息
对于（int i=0；i
任何可靠的解析器在这方面都应该没有问题。你只需要了解它是什么。去json.org学习语法——学习只需要5-10分钟，然后事情就会变得更有意义。请注意，试图复制别人的json处理代码通常是一件傻事，因为代码必须不同（从根本上说）基于JSON的结构。（你的代码中有几处完全错误——基本上是胡说八道。）（不幸的是，你的JSON太长了，无法进行后期格式化，但你可以通过将其粘贴到at来查看格式化的JSON，缩进会使它更容易理解。）这是胡说八道：
forecast.getJSONObject（Integer.parseInt（“simpleforecast”）
。这是一种艰难的做法，没有什么好的理由：
newjsonarray（data.getJSONArray（“forecast”）.toString（））
谢谢，这确实帮助我理解了我的错误所在。

    JSONArray forecastDay = txtForecast.getJSONArray("forecastday");
