如何在Android中停止计时器? [英] How to stop the Timer in android?

问题描述

我正在开发一个在特定时间段内将消息发送到特定号码的应用程序. 问题在于它会在该时间段后继续发送该消息.我如何在该特定时间后停止计时器以停止发送该消息?

I'm developing an application which sends a message to a specific number in a specific period of time. The problem is that it continues sending that message after that period of time. How would I stop the timer after that specific time in order to stop sending that message?

推荐答案

     CountDownTimer waitTimer;
     waitTimer = new CountDownTimer(60000, 300) {

       public void onTick(long millisUntilFinished) {
          //called every 300 milliseconds, which could be used to
          //send messages or some other action
       }

       public void onFinish() {
          //After 60000 milliseconds (60 sec) finish current 
          //if you would like to execute something when time finishes          
       }
     }.start();

提早停止计时器:

     if(waitTimer != null) {
         waitTimer.cancel();
         waitTimer = null;
     }
