Android程序之聚合数据全国天气预报查询API接口使用演示
一、项目演示效果如下：
二、使用 聚合数据SDK：
（1）我使用的是聚合数据上的天气预报查询，地址： https://www.juhe.cn/docs/api/id/39（2）注册账号—创建一个新应用（在个人中心页面—数据中心—申请数据）–填入自己的应用–找到分类–天气预报—全国天气预报
（3）下载sdk：https://www.juhe.cn/juhesdk/download
（4）参考开发文档：https://www.juhe.cn/juhesdk/adocs
接下来介绍了聚合数据SDK的初始化和权限的使用！
三、项目介绍
（1）项目截图（2）WeatherApplication.java这里作为sdk的初始化
这里是初始化聚合数据的SDK需要在application中添加 android:name="com.juhe.weather.WeatherApplication@author xuliugen/public class WeatherApplication extends Application {@Overridepublic void onCreate() { super.onCreate(); // 使用聚合SDK需要初始化的过程CommonFun.initialize(getApplicationContext());}
}我们需要在清单文件中加入：
android:name="com.juhe.weather.WeatherApplication"
（3）返回的json数据格式
{"resultcode": "200","reason": "successed!","result": {"sk": {"temp": "19","wind_direction": "西北风","wind_strength": "1级","humidity": "37%","time": "16:00"},"today": {"temperature": "5℃~19℃","weather": "多云转阴","weather_id": {"fa": "01","fb": "02"},"wind": "南风微风","week": "星期五","city": "成都","date_y": "2015年03月13日","dressing_index": "较舒适","dressing_advice": "建议着薄外套、开衫牛仔衫裤等服装。年老体弱者应适当添加衣物，宜着夹克衫、薄毛衣等。","uv_index": "最弱","comfort_index": "","wash_index": "较适宜","travel_index": "","exercise_index": "较不宜","drying_index": ""},"future": {"day_20150313": {"temperature": "5℃~19℃","weather": "多云转阴","weather_id": {"fa": "01","fb": "02"},"wind": "南风微风","week": "星期五","date": "20150313"},"day_20150319": {"temperature": "10℃~18℃","weather": "阴","weather_id": {"fa": "02","fb": "02"},"wind": "南风微风","week": "星期四","date": "20150319"}}},"error_code": 0
}
未来三天的json数据格式：
{"resultcode": "200","reason": "successed!","result": [{"weatherid": "01","weather": "多云","temp1": "16","temp2": "13","sh": "17","eh": "20","date": "20150313","sfdate": "20150313170000","efdate": "20150313200000"},{"weatherid": "02","weather": "阴","temp1": "19","temp2": "16","sh": "11","eh": "17","date": "20150320","sfdate": "20150320110000","efdate": "20150320170000"}],"error_code": 0
}（4）根据上述的json格式，我们需要创建相应的json试题对象，其中为了更好的处理，分别建立相应的类
上图中就是含有包含关系的json数据，容易出错！特此标记出来！
（5）WeatherService.java主要是处理后台服务的类，将数据的加载放在后台！
注意的是：
这里的白色部分的数值是在聚合数据上申请的时候的OpenID（在个人中心的中心可以找到OpenID！）
