英文:
Best practice stop thread when finish processing queue
问题
我正在尝试理解最佳实践，以便创建一个线程，确保排队的消息以同步方式执行，并且一旦没有更多消息需要处理，线程就会自行结束。
我已阅读了Handler和ServiceExecutor的文档，并且发现ExecutorService的submit方法返回一个Future对象，我可以从中调用Future.get()，但这样我就需要另一个线程在Runnable的执行完成时得到通知。
另外在Executor的文档中，他们有一个SerialExecutor的示例，在这里我猜我可以检查队列的大小以便结束线程。
老实说，我认为肯定有更好的方法来实现这种行为，所以我想知道什么是最佳实践。
编辑：
我并不是一次性拥有所有的消息，所以我不知道线程何时会停止，除非我想要强制终止它。如果没有特定的条件，我希望它一直运行，直到完成处理所有消息。
英文:
I'm trying to understand which would be the best practice to have a thread which ensures that the messages queued are executed in a synchronous way and it finishes itself once it hasn’t more messages to process.
I've been reading the documentation of Handler and ServiceExecutor and I found ExecutorService's submit method returns a Future object from which I could call Future.get() but then I would need another thread to be noticed when the execution of the Runnable has finished.
Also on Executor's doc they have a SerialExecutor example where I guess that I could check the size of the queue in order to finish the thread.
Honestly I think that there has to be a better way to achieve this behaviour, so I was wondering which is the best practice.
Edit:
I don't have all the messages at once, so I don't know when the thread will stop or until I want to force it to stop. If not, I'd like to keep running until it has finished processing all the messages.
