问题描述
我创造100分钟延时定时器关机服务,如果它没有完成。看起来是这样的:
I create 1 minute delayed timer to shutdown service if it's not completed. Looks like this:
private Handler timeoutHandler = new Handler();
里面的onCreate()
inside onCreate()
timeoutHandler.postDelayed(new Runnable()
{
public void run()
{
Log.d(LOG_TAG, "timeoutHandler:run");
DBLog.InsertMessage(getApplicationContext(), "Unable to get fix in 1 minute");
finalizeService();
}
}, 60 * 1000);
如果我得到工作之前,这个1分钟完成 - 我希望得到取消,但不是这个延迟的事情知道如何
If I get job accomplished before this 1 minute - I would like to get this delayed thing cancelled but not sure how.
推荐答案
您不能真正做到这一点有一个匿名的Runnable。如何拯救了Runnable到一个名为变量?
You can't really do it with an anonymous Runnable. How about saving the Runnable to a named variable?
Runnable finalizer = new Runnable()
{
public void run()
{
Log.d(LOG_TAG, "timeoutHandler:run");
DBLog.InsertMessage(getApplicationContext(), "Unable to get fix in 1 minute");
finalizeService();
}
};
timeoutHandler.postDelayed(finalizer, 60 * 1000);
...
// Cancel the runnable
timeoutHandler.removeCallbacks(finalizer);
