停止线并重新启动黑莓给人IllegalThreadStateException [英] Stop thread and again start giving IllegalThreadStateException in blackberry

问题描述

我使用以下code时获得 IllegalThreadStateException 例外：
我已经开始这个线程一次（使用 thread.start（）），并再次试图在其他地方开始，所以下面用code：

I am getting IllegalThreadStateException exception when using following code: I have already started this thread once(by using thread.start()) and again trying to start it at another place, so used following code:

thread.interrupt();
thread.start();

但 thread.start（）抛出 IllegalThreadStateException 。

我应该使用什么来解决呢？

What should I use to solve it?

推荐答案

发对象只是为了启动一次。如果你需要停止/中断发，然后想再次启动它，你应该创建一个新的实例，并调用开始（）就可以了：

Thread objects are only meant to be started once. If you need to stop/interrupt a Thread, and then want to start it again, you should create a new instance, and call start() on it:

thread.interrupt();  // if you need to make sure thread's run() method stops ASAP
thread = new MyThreadSubclass();
thread.start();

从API文档

IllegalThreadStateException - 如果线程已经启动

IllegalThreadStateException - if the thread was already started.

我知道这不是100％的清楚，你不能叫开始（）再次，即使你previously名为中断（ ），但这是它的工作方式。

I know it's not 100% clear that you can't call start() again, even if you previously called interrupt(), but that's the way it works.

如果你看一下 API文档对于标准的Java ，这个问题更加清晰。

If you look at the API docs for standard Java, this issue is more clear.
