Android Complex JSON parsing

There are two kinds of structures for JSON construction: ObjectAnd Array
JSON is simply called objects and arrays in JavaScript, so these two structures are objects and arrays of 2 structures that can represent a variety of complex structures.
The following is a JSON format in the project, it is not very complicated, post the parsing method and thinking:

{"Result": true, "Msgtype": 3, "count": +, "BatchId": "hb20140711", "Companyfullname": "Hubei Province network Bo Exhibition Co., Ltd.", "Goodsid": "P002", "Goodsname": "Hubei ge Dian Internet Industry Exposition", "Goodsdes": "3as.jpg", "goodsimg": "/company/download/goods_img/ 9a036-4c39-418d-a1d7-d5dadba66ab3.jpg "," menulist ": [{" title ":" Exhibitor Guide "," Menucontent ":" c.jpg\ "" c2.jpg\ "" C3.jpg\ ""}, {"title": "Exhibitor", "menucontent": "? Exhibitor List 1XXX Investment Co., Ltd. 2XXX Network Technology Co., Ltd. 3XXX Zhai Technology Co., Ltd."},{"title": "Exhibition Overview", "Menucontent": "Exposition Status one, Expo venue and schedule: August 2014 14-15th           08:30-17:00                  Launch date: August 16, 2014            08:30-17:00          August 17, 2014             08:30-17:00        August 18, 2014           08:30-14:00        "}]}

Analysis:1. A single entity has a multiple attribute 2. There is a collection in the Entity 3. The collection also has its own properties
Solution: 1. Create entity (entity of commodity information, entity in collection Menulist) 2. list< Collection Menulist entity >3 is created in the commodity entity class. Add Menulist collection to the base product information after parsing it
Commodity entity information: Goodsresultinfo.java

the final use and results:

           Parse result data, pass to page display            goodsresultinfo mgoodslist = Goodsresultparser.parsejson (result);            Intent resultintent = new Intent (this,goodsdetailsactivity.class);            Resultintent.putextra (result,mgoodslist);            StartActivity (resultintent);

Results:

Goodsresultinfo [batchid=hb20140711, Count=16, companyfullname= Hubei Province network Bo Exhibition Co., Ltd., goodsdes=<p><a target= "_self" href= "http://www.365yunshang.com/10805" ></A></P>, goodsid=p002, goodsImg=/company/ Download/goods_img/937ea036-4c39-418d-a1d7-d5dadba66ab3.jpg, Goodsname=, Menulist=null, msgType=3, Hubei ge Dian Internet Industry Exposition Result=true, Mgoodsresultitem=[[email protected], [email protected], [email protected]]

Of course, this kind of solution is not necessarily the most perfect, can also introduce third-party open-source jar to complete, but the internal implementation method and principle are similar. (This method is for reference only)
