android 如何停止 mHandler.postDelayed

Question

我有一个应用程序，我将 mHandler 用作计时器......它工作正常，然后 Runnable MuPdeteTimeTask 工作......这是一个代码......

    mHandlerTime.removeCallbacks(mUpdateTimeOutTask);
                mHandlerTime.postDelayed(mUpdateTimeOutTask, delay_timeoutzz);   

......................................

    private Runnable mUpdateTimeOutTask = new Runnable() {
           public void run() {
               Toast.makeText(getApplicationContext(), "TimeOut of session is reached! Session will be force closed!", Toast.LENGTH_LONG).show();
               new UploadTask().onCancelled();
                       }
        };

我怎么能阻止它或想定义“延迟”的新含义？？？？

Answer 1

你肯定可以做这样的事情，

取两个变量，

boolean delayedAgain = false;
long newDelayedTimeFromNow=5000;

然后在您的可运行应用逻辑中，

Runnable  mUpdateTimeOutTask = new Runnable() {             
            @Override
            public void run() {
                if(delayedAgain)
                {
                    delayedAgain = false;
                    mHandlerTime.postDelayed(this, newDelayedTimeFromNow);  
                    return;
                }
                else
                {
                    // DO JOB ON TIME.
                }                   
            }
        };

现在从你的另一个任务，

if(somethingIsDone)
{
  delayedAgain = true;
  newDelayedTimeFromNow = 3000;
}
