我一直在寻找一段时间,想要一种方法来排序这样的
JSON对象：
{"results": [
{
"layerId": 5,"layerName": "Pharmaceutical Entities","attributes": {
"OBJECTID": "35","FACILITYTYPE": "Pharmacy","FACILITYSUBTYPE": "24 Hr Pharmacy","COMMERCIALNAME_E": "SADD MAARAB PHARMACY"
},"geometryType": "esriGeometryPoint",},{
"layerId": 5,"attributes": {
"OBJECTID": "1","COMMERCIALNAME_E": "GAYATHY HOSPITAL PHARMACY"
},"attributes": {
"OBJECTID": "255","COMMERCIALNAME_E": "AL DEWAN PHARMACY"
},}
]}
并按“COMMERCIALNAME_E”的值按字母顺序排序：
{"results": [
{
"layerId": 5,"geometryType": "esriGeometryPoint"
},"COMMERCIALNAME_E": "GAYATHY HOSPITAL PHARMACY"
},"geometryType": "esriGeometryPoint"
}
]}
我找不到任何可以执行此操作的代码.谁能给我一些帮助？
解决方法
将这些JSON解析为对象集合,并使用比较器使用首选字段对其进行排序.
> Use GSON to parse it to collection of objects
例：
import com.google.gson.Gson;
class Person {
private int age;
private String name;
}
String json = "{'age':22,'name':'Jigar'}";
Gson gson = new Gson();
TestJsonFromObject obj = gson.fromJson(json,Person.class);
如果要从Object创建JSON.
Person p = new Person();
p.setName("Jigar");
p.setAge(22);
String jsonStr = new com.google.gson.Gson().toJson(obj);
