队列线程黑莓 [英] Queue Thread In Blackberry

问题描述

我看了看BB API（5.0），我无法找到连续执行批处理线程的任何方式。我知道BB对螺纹将推出的数量是有限的，所以我不想推出7如果用户点击贯穿东西速度不够快，但我无法找到像一个线程池什么。

I've looked at the BB API(5.0) and I can't find any way of serially executing a batch of threads. I know BB has a limit on the number of threads it will launch, so I don't want to launch 7 if the user clicks through things fast enough but I cannot find anything like a thread pool.

有一个简单的定为这还是我要创建一个数据结构？

Is there an easy fix for this or do I have to create a data structure?

推荐答案

如果你只是想在一个单线程串行执行一串任务和顺序并不重要，你可以创建一个的Timer 对象（它有其自己的线程），那么每个任务添加到它作为一个TimerTask 。如果您使用的0或1的延迟安排，它会基本上是尽快运行任务。而且，由于一个定时器只有一个线程，如果您安排多个任务的同时，将确保只有一个会同时运行。

If you just want to execute a bunch of tasks on a single thread serially and order isn't important, you could create a Timer object (which has its own thread) then add each task to it as a TimerTask. If you schedule it with a delay of 0 or 1, it will essentially run that task as soon as possible. And since a Timer only has a single thread, if you schedule multiple tasks concurrently, it will ensure that only one will run at a time.

顺便说一句，我是在黑莓开发者大会上，今年说给RIM的工程师，他说，作为OS 5.0中不再有限制了线程的数量 - 所以，这正成为越来越少的关注。

Incidentally, I was talking to a RIM engineer at the BlackBerry Developer Conference this year and he said that as of OS 5.0 there are no longer limits to the number of threads -- so this is becoming less and less of a concern.
