you have parse json response , store different categories in different arraylist , based on user selection of render position can use selected arraylist.

you can parsing json response this

jsonobject jsonobject = new jsonobject(response); // response json string gettting server      jsonarray jsonarray = jsonobject.getjsonobject("product_categories");      arraylist<categorydisplay> catdislist = new arraylist<>();     arraylist<defaultdisplay> defaultdislist = new arraylist<>();      (int = 0; < jsonarray.length(); i++) {         jsonobject jsonobject = jsonarray.getjsonobject(i);         somemodel somemodel = new somemodel();         if (jsonobject.has("id")) {             somemodel.setid(jsonobject.getstring("id"));         }         if (jsonobject.has("name")) {             somemodel.setname(jsonobject.getstring("name"));         }          on.....          if(somemodel.getdisplay().equals("default")){             defaultdislist.add(somemodel);         }else{             catdislist.add(somemodel);         }      }
