我正在开发Android应用程序;注册用户并使用网络服务向注册用户提供服务......
现在如何使用我的应用注册用户？...这是服务代码。
Web服务：
{"USERDETAIL DETAIL":[{"post":{"id":"42","fname":"hanif","lname":"khan","address":"Dhok Saiydan Road, Rawalpindi City, Pakistan","cellno":"1234","phone":"23444","email":"hukhan.surrani@gmail.com","experience":"6 year","category":"Auto","subcategory":"Auto Painting","password":"123","latitude":"33.570858","longitude":"73.048553","dated":"2015-09-11 12:10:23","last_loggedin":"2015-10-02 05:56:08","status":"1","last_profile_updated":"0000-00-00 00:00:00","active_code":"0","profile_image":"1441969837test.png"}}

这取决于您的服务器端，我建议使用Retrofit

然后尝试创建这个json的POJO类
{
"USERDETAIL DETAIL": [
{
"post": {
"id": "42",
"fname": "hanif",
"lname": "khan",
"address": "Dhok Saiydan Road, Rawalpindi City, Pakistan",
"cellno": "1234",
"phone": "23444",
"email": "hukhan.surrani@gmail.com",
"experience": "6 year",
"category": "Auto",
"subcategory": "Auto Painting",
"password": "123",
"latitude": "33.570858",
"longitude": "73.048553",
"dated": "2015-09-11 12:10:23",
"last_loggedin": "2015-10-02 05:56:08",

"active_code": "0",
"profile_image": "1441969837test.png"
}
}
]
}
即。 AppUser.java

现在..将你的json序列化为这个POJO对象
Gson gson=new Gson();
AppUsers appUsersObject=gson.fromJson(<your json>.toString(), AppUsers.class);
将Gson库添加到项目中
在Android工作室编译＆＃39; com.google.code.gson：gson：2.3.1＆＃39; 在eclipse gson.jar（谷歌和下载）
现在将UserdetailEntity对象添加到List userdetail;
PostEntity postEntity=new PostEntity();
postEntity.setId("newid"); // add all the attributes of postentity
UserdetailEntity userdetail=new UserdetailEntity();
userdetail.setPost(postEntity);
appUsersObject.getUserdetail().add(userdetail);
基本上，现在你必须处理这个＆＃34; appUsersObject＆＃34;而不是json字符串...因为你可以轻松处理这个对象..添加/删除/更新到这个对象，并通过会话在你的app中工作..
您可以将此AppUsers.java类创建为Singleton类
