是否Thread.sleep（）方法，使UI线程睡觉？ [英] Does Thread.sleep() makes the UI Thread to sleep?

问题描述

这会不会使当前UI线程睡觉？

 尝试
{
   视频下载（20）;
   onProgressUpdate（ⅰ）;
}赶上（InterruptedException异常E）{
      e.printStackTrace（）;
}
 

解决方案

如果你调用睡在UI线程阻塞UI线程。不要叫睡在UI线程上。你不应该阻止用户界面线程。

http://docs.oracle.com/javase/tutorial/至关重要/并发/ sleep.html

您会得到ANR

如果您实施发或 HandlerThread ，确保在等待工人的UI线程不会阻止线程完成，不叫 Thread.wait（）或视频下载（）。

另外，请检查下如何避免ANRS的话题

Will this make the current UI thread to sleep?

try 
{
   Thread.sleep(20);
   onProgressUpdate(i);
} catch (InterruptedException e) {
      e.printStackTrace();
}

解决方案

If you are calling sleep on the ui thread it blocks the ui thread. Do not call sleep on the ui thread. You should not block the ui thread.

http://developer.android.com/reference/java/lang/Thread.html

http://docs.oracle.com/javase/tutorial/essential/concurrency/sleep.html

You will get ANR

If you implement Thread or HandlerThread, be sure that your UI thread does not block while waiting for the worker thread to complete—do not call Thread.wait() or Thread.sleep().
