Question

我希望在系统时间戳到达特定时间时调用一个函数。无论如何比CountDownTimer好吗？应该在服务上调用它，因为我希望它在应用程序关闭时仍然运行。

非常感谢。

你必须使用BroadcastReceiver和AlarmManager这样。

//Create alarm manager
AlarmManager malarmMngr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);

//Create pending intent & register it to your alarm notifier class
Intent intent = new Intent(this, yourBroadcastReceiver.class);
PendingIntent mPendInt = PendingIntent.getBroadcast(this, 0, intent, 0);

//set your time stamp (for once in future)
malarmMngr .set(AlarmManager.RTC_WAKEUP, yourtimestamp, mPendInt);

现在创建yourBroadcastReceiver类来调用函数。

public class yourBroadcastReceiver extends BroadcastReceiver {
    public MyReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // This method is called when this BroadcastReceiver receives an Intent broadcast.
        // Call your function here
    }
}

在特定时间戳调用函数的最佳方法
