Java的线程错误IllegalThreadState线程已经启动 [英] Java Threading Error IllegalThreadState thread already started

问题描述

每当我开始我的主题我总是做此项检查。我没有找到任何地方，我呼吁启动线程而不做以下

Whenever I start my thread I always do this check. I did not find anywhere that I called start on thread without doing the check below

if (!myThread.isAlive())
    myThread.start();

不过，我最终IllegalThreadStateException：线程已经启动。这实际上崩溃我的应用程序（机器人）。那么，有没有一些其他的检查，我需要启动一个线程之前做？

Nevertheless, I end up with IllegalThreadStateException : Thread already started. This actually crashes my app (android). So is there some other check I need to do before starting up a thread?

推荐答案

您应该检查线程已经开始使用<一个href="http://download.oracle.com/javase/1.5.0/docs/api/java/lang/Thread.html#getState%28%29">getState()并启动它仅当它的状态是NEW ，否则，创建新的线程（如果需要）。

You should check if the thread has already started using getState() and start it only if its state is NEW, otherwise create new thread (if needed).
