andriod链接sql server 数据库
我用andriod通过web service链接sql server 数据库;下面是链接数据库时的两个类，但是返回回来的总是空值，请大家帮我看下package com.example.stock;

import java.sql.DriverManager;

sql server webservice android模拟器 数据库 --------------------编程问答-------------------- 怎么没人说话啊，我断点跟踪时总是跑到System.out.println("退出" + vs); 来 --------------------编程问答-------------------- j = TS.indexOf(ifString);

如果找到了字符串，
k>j就跑到退出的地方了。 --------------------编程问答-------------------- 为什么会这样呢，public ArrayList<String> inputStreamtovaluelist 总是返回空值
