多线程更新UI 系统死掉报stop Woring

Question

--： Thread updateThread = new Thread(updateList);//更新列表线程--

哪位能帮解决下。

Answer 1

正常运行没有问题！运行一会就就报Stop working错，

Answer 2

重新学习多线程、异步流程设计。把你的所有的 Thread.Sleep 语句都删除掉！这里，一个好的控制程序，一定不是不写 Sleep 的高运行效率低资源占用的程序。

Answer 3

你把所有的 Thread.Sleep 语句删除掉，就能完整搞懂这类程序设计模式。如果还拿这“死循环+阻塞”的思路去模拟事件驱动程序设计思路，终究只是玩一玩儿刚学线程概念时的小 demo，只能做少量的简单工作。

Answer 4

backgroundWorker 组件。在里面写代码。自动帮你处理费那个劲

Answer 5

 
能说的详细点么？万分感谢。刚接触多线程，本来以为很简单，就按硬件提供的Demo写了，结果

Answer 6

按你的提示用了backgroundWorker组件；稳定性确实提升了。性能还是没得到有效控制。
