android原生JSON解析实例
我们在android项目开发的时候，经常要对JSON进行解析，很多朋友在寻找相关的实例，小编整理详细的相关分析说明，一起来看下。
JSONObject：JSON数据封装对象
JSONArray：JSON数据封装数组
Bean:
packagenet.bwie.jsonobject;
importjava.util.List;
publicclassShoppingBean{
privateStringmsg;
privateInfoBeaninfo;
publicStringgetMsg(){
returnmsg;
}
publicvoidsetMsg(Stringmsg){
this.msg=msg;
}
publicInfoBeangetInfo(){
returninfo;
}
publicvoidsetInfo(InfoBeaninfo){
this.info=info;
}
@Override
publicStringtoString(){
return"ShoppingBean{"+
"msg='"+msg+'\''+
",info="+info+
'}';
}
publicstaticclassInfoBean{
privateintcat_id;
privateListgood;
privatebooleanurl;
publicintgetCat_id(){
returncat_id;
}
publicvoidsetCat_id(intcat_id){
this.cat_id=cat_id;
}
publicListgetGood(){
returngood;
}
publicvoidsetGood(Listgood){
this.good=good;
}
publicbooleanisUrl(){
returnurl;
}
publicvoidsetUrl(booleanurl){
this.url=url;
}
@Override
publicStringtoString(){
return"InfoBean{"+
"cat_id="+cat_id+
",good="+good+
",url="+url+
'}';
}
publicstaticclassGoodsBean{
privatelongadd_time;
privateStringcolorcode;
privateStringcurrency_price;
privateStringdescription;
privateStringgoods_id;
privateStringgoods_name;
privateStringthumb;
publiclonggetAdd_time(){
returnadd_time;
}
publicvoidsetAdd_time(longadd_time){
this.add_time=add_time;
}

publicvoidsetCurrency_price(Stringcurrency_price){
this.currency_price=currency_price;
}
publicStringgetDescription(){

this.description=description;

publicStringgetGoods_id(){

}
publicvoidsetGoods_id(Stringgoods_id){
this.goods_id=goods_id;
}
publicStringgetGoods_name(){
returngoods_name;
}
publicvoidsetGoods_name(Stringgoods_name){
this.goods_name=goods_name;

'}';
}
}
}
}
