android 计时器CountDownTimer 安卓计时器代码 一、基本定义 Chronometer(计时器)组件与DigitalClock都继承自TextView,因此他们都会显示一段文本。但Chrnometer并不显示当前时间,它显示的是从某个起始时间开始,一共过去了多长时间。 二、属性和方法 1、属性:Chronometer(计时器)组件用法比较简单,它只提供了一个android:...
查看CountDownTimer 源码(API 25), 发现start() 中计算的 mStopTimeInFuture(未来停止倒计时的时刻,即倒计时结束时间) 加了一个 SystemClock.elapsedRealtime() ,系统自开机以来(包括睡眠时间)的毫秒数,后文中以“系统时间戳”简称。 即倒计时结束时间为“当前系统时间戳 + 你设置的倒计时时长 mMillisInFuture ...
