android客户端登录&注册的实现

MainActivity多线程的实现：

UserService 接口：

package com.example.loginconnect.service;

import org.json.JSONObject;

public interface UserService {

	public void userLogin(String loginName, String loginPassword)

			throws Exception;

	public void userResign(String loginName, String loginPassword,String surePassword,

			String realName, String cellphone1, String cellphone2,

			String cellphone3) throws Exception;

	public JSONObject selectUser(String loginName, String realname,

			String cellphone1, String cellphone2, String cellphone3)

			throws Exception;

}
