【问题描述】：
当我单击检查按钮时，应用程序在处理作业时停止。
我想获得实时结果。
这是我的代码。
我用这个应用程序检查了一些雅虎帐户。
点击check的时候我想一个一个的得到结果，但是点击check的时候必须等到所有的账户都被check之后才能得到结果。

【问题讨论】：
-
您必须让您的应用程序异步运行，以便获得非阻塞 UI，例如，通过在新的
Thread中运行您的checkcurrent()方法。这里有一个关于 Java 多线程的教程：beginnersbook.com/2013/03/multithreading-in-java -
感谢我是新的 Java 编码器，你能修改我的代码吗？
