Android parses Json data of China weather network

Android parses Json data of China weather network

In Android development, a general APP updates the UI by obtaining server-side data. The data obtained from the server can be Json, and the data size is smaller than that of XML, here, we will analyze the data obtained on the Chinese weather network. Although it is no longer updated, it is still possible to learn it. For convenience, I can directly store the data to the local through txt, its data can be obtained through this page: http://m.weather.com.cn/data/101280601.html

Directory structure

In fact, the resolution is also very simple, key code

 

Private void json3 () {InputStream inputStream = null; String weatherinfo = null; try {System. out. println (pipeline> json3); inputStream = pipeline); weatherinfo = convertStreamToString (inputStream);} catch (IOException e1) {// TODO Auto-generated catch blocke1.printStackTrace ();} // obtain JSONObject jsonobject = null; JSONObject jsoncity = null; try {jsonobject = new JSONObject (weatherinfo); jsoncity = new JSONObject (jsonobject. getString (weatherinfo); WeatherInfo info = new WeatherInfo (); info. city = jsoncity. getString (city); info. cityid = jsoncity. getString (cityid); info. city_en = jsoncity. getString (city_en); info. date = jsoncity. getString (date); info. date_y = jsoncity. getString (date_y); info. fchh = jsoncity. getString (fchh); info. fl [0] = jsoncity. getString (fl1); info. fl [1] = jsoncity. getString (fl2); info. fl [2] = jsoncity. getString (fl3); info. fl [3] = jsoncity. getString (fl4); info. fl [4] = jsoncity. getString (fl5); info. fl [5] = jsoncity. getString (fl6); info. fx [0] = jsoncity. getString (fx1); info. fx [1] = jsoncity. getString (fx2); info. img [0] = jsoncity. getString (img1); info. img [1] = jsoncity. getString (img2); info. img [2] = jsoncity. getString (img3); info. img [3] = jsoncity. getString (img4); info. img [4] = jsoncity. getString (img5); info. img [5] = jsoncity. getString (img6); info. img [6] = jsoncity. getString (img7); info. img [7] = jsoncity. getString (img8); info. img [8] = jsoncity. getString (img9); info. img [9] = jsoncity. getString (img10); info. img [10] = jsoncity. getString (img11); info. img [11] = jsoncity. getString (img12); info. img_single = jsoncity. getString (img_single); info. img_title [0] = jsoncity. getString (img_title1); info. img_title [1] = jsoncity. getString (img_title2); info. img_title [2] = jsoncity. getString (img_title3); info. img_title [3] = jsoncity. getString (img_title4); info. img_title [4] = jsoncity. getString (img_title5); info. img_title [5] = jsoncity. getString (img_title6); info. img_title [6] = jsoncity. getString (img_title7); info. img_title [7] = jsoncity. getString (img_title8); info. img_title [8] = jsoncity. getString (img_title9); info. img_title [9] = jsoncity. getString (img_title10); info. img_title [10] = jsoncity. getString (img_title11); info. img_title [11] = jsoncity. getString (img_title12); info. img_title_single = jsoncity. getString (img_title_single); info. temp [0] = jsoncity. getString (temp1); info. temp [1] = jsoncity. getString (temp2); info. temp [2] = jsoncity. getString (temp3); info. temp [3] = jsoncity. getString (temp4); info. temp [4] = jsoncity. getString (temp5); info. temp [5] = jsoncity. getString (temp6); info. tempF [0] = jsoncity. getString (tempF1); info. tempF [1] = jsoncity. getString (tempF2); info. tempF [2] = jsoncity. getString (tempF3); info. tempF [3] = jsoncity. getString (tempF4); info. tempF [4] = jsoncity. getString (tempF5); info. tempF [5] = jsoncity. getString (tempF6); info. weather [0] = jsoncity. getString (weather1); info. weather [1] = jsoncity. getString (weather2); info. weather [2] = jsoncity. getString (weather3); info. weather [3] = jsoncity. getString (weather4); info. weather [4] = jsoncity. getString (weather5); info. weather [5] = jsoncity. getString (weather6); info. week = jsoncity. getString (week); info. wind [0] = jsoncity. getString (wind1); info. wind [1] = jsoncity. getString (wind2); info. wind [2] = jsoncity. getString (wind3); info. wind [3] = jsoncity. getString (wind4); info. wind [4] = jsoncity. getString (wind5); info. wind [5] = jsoncity. getString (wind6); info. img_title [0] = jsoncity. getString (img_title1); System. out. println (json = + info. toString ();} catch (JSONException e) {e. printStackTrace ();}}

I encapsulate the weather information separately.

Parsed result

Several websites can check Json data to see if the Json format is standard.

Http://jsonviewer.stack.hu/

Http://json.parser.online.fr/

These websites can format Json data for convenience.

If the format is incorrect, a prompt will be displayed to facilitate modification. Note that line breaks are not allowed when creating a file to save Json data.

Which of the following is false for our convenience?
