Handler 的postDelayed 这方法的作用是什么?
public final boolean postDelayed(Runnable r, long delayMillis)
看英文文档 没看明白。。。
求解释
Causes the Runnable r to be added to the message queue, to be run
* after the specified amount of time elapses.
(前后的懂,下面这句就悲催了)
* The runnable will be run on the thread to which this handler
* is attached.
==========
网上说 每 delayMillis 执行一次, 为啥我测试一下 只执行一次?
这是为啥?
=========================
还有哪位明白人顺便把post 等该方法中的postAtTime等其他方法也解释一下
不胜感激
