Ii. Use the aggregate data SDK:
(1) aggregated data official website address: http://www.juhe.cn/
(2) register an account-create a new application (on the personal Center page-Data Center-apply for data)-enter your application-find category-Weather Forecast-National Weather Forecast
(3) download the sdk (because the project uses a version of, please download: Included in my project !)
(4) Reference development documents: http://www.juhe.cn/juhesdk/adocs
This section describes the initialization and permission usage of the aggregate data SDK!
Iii. Project Introduction
(1) project
(2) WeatherApplication. java is used as sdk initialization.
Package com. juhe. weather; import com. thinkland. juheapi. common. commonFun; import android. app. application;/*** here is the SDK for initializing aggregated data. ** you need to add android: name = "com. juhe. weather. weatherApplication ** @ author xuliugen **/public class WeatherApplication extends Application {@ Override public void onCreate () {super. onCreate (); // use the aggregation SDK to initialize CommonFun. initialize (getApplicationContext ());}}
We need to add the following to the configuration file:
android:name="com.juhe.weather.WeatherApplication"
(3) returned json Data Format
{"Resultcode": "200", "reason": "successed! "," Result ": {" sk ": {" temp ":" 19 "," wind_direction ":" northwest wind "," wind_strength ":" Level 1 ", "humidity": "37%", "time": "16:00"}, "today": {"temperature": "5 ℃ ~ 19 ℃ "," weather ":" Cloudy to overcast "," weather_id ": {" fa ":" 01 "," fb ":" 02 "}," wind ": "Nanfeng Breeze", "week": "Friday", "city": "Chengdu", "date_y": "August March 13, 2015", "dressing_index": "More comfortable ", "dressing_advice": "We recommend that you wear thin coats, denim shirts, and other clothing. Old and weak people should add appropriate clothing, and should wear jackets and thin sweaters. "," Uv_index ":" weakest "," comfort_index ":" "," pai_index ":" More suitable "," travel_index ":" "," exercise_index ": "Not suitable", "drying_index": ""}, "future": {"day_20150313": {"temperature": "5 ℃ ~ 19 ℃ "," weather ":" Cloudy to overcast "," weather_id ": {" fa ":" 01 "," fb ":" 02 "}," wind ": "Nanfeng Breeze", "week": "Friday", "date": "20150313"}, "day_20150319": {"temperature": "10 ℃ ~ 18 ℃ "," weather ":" Overcast "," weather_id ": {" fa ":" 02 "," fb ":" 02 "}," wind ": "Nanfeng Breeze", "week": "Thursday", "date": "20150319" }}, "error_code": 0} json data format for the next three days: {"resultcode": "200", "reason": "successed! "," Result ": [{" weatherid ":" 01 "," weather ":" Multi-cloud "," temp1 ":" 16 "," temp2 ":" 13 ", "sh": "17", "eh": "20", "date": "20150313", "sfdate": "20150313170000", "efdate ": "20150313200000" },{ "weatherid": "02", "weather": "Yin", "temp1": "19", "temp2": "16 ", "sh": "11", "eh": "17", "date": "20150320", "sfdate": "20150320110000", "efdate ": "20150320170000"}], "error_code": 0}
(4) based on the preceding json format, we need to create corresponding json question objects. For better processing, we need to create corresponding classes respectively.
Contains json data containing links, which is prone to errors! Mark it!
(5) WeatherService. java is mainly used to process Background services and load data in the background!
Note:
Here, the value of the white part is the OpenID applied for on the aggregated data (you can find the OpenID on the home page of the personal center !)
