JAVA中用代码自己创建一个JsonObject对象

JsonObject object=new JsonObject();
JsonArray array=new JsonArray();
JsonObject lan1=new JsonObject();
lan1.addProperty("type", 1);
lan1.addProperty("timing", "40:20");
lan1.addProperty("time", "2016-06-23 13:44:40");
lan1.addProperty("price", "40.20");
lan1.addProperty("mainprice", "40.20");
lan1.addProperty("productname", "香薰SOD密 润肤奶膏身体乳");
array.add(lan1);
JsonObject lan2=new JsonObject();
lan2.addProperty("type", 2);
lan2.addProperty("time", "2017-06-23 13:44:40");
lan2.addProperty("timing", "22:10");
lan2.addProperty("price", "22.10");
lan2.addProperty("mainprice", "22.10");
lan2.addProperty("productname", "男女夏季补水祛痘淡印芦荟膏");
array.add(lan2);
JsonObject lan3=new JsonObject();
lan3.addProperty("type", 3);
lan3.addProperty("time", "2018-06-23 13:44:40");
lan3.addProperty("timing", "41:30");
lan3.addProperty("price", "41.30");
lan3.addProperty("mainprice", "41.30");
lan3.addProperty("productname", "精美剪刀一把");
array.add(lan3);
object.add("data", array);
Log.i("object=",object+"");

打印出：

 I/object=: {"data":[{"type":1,"timing":"40:20","time":"2016-06-23 13:44:40","price":"40.20","mainprice":"40.20","productname":"香薰SOD密 润肤奶膏身体乳"},
         {"type":2,"time":"2017-06-23 13:44:40","timing":"22:10","price":"22.10","mainprice":"22.10","productname":"男女夏季补水祛痘淡印芦荟膏"},
         {"type":3,"time":"2018-06-23 13:44:40","timing":"41:30","price":"41.30","mainprice":"41.30","productname":"精美剪刀一把"}]}
