java - 如何在android中每天的特定时间做某事

Question

我想在每天上午 9:00 检查一些 url。但是我该怎么做呢？我确实检查了一些关于 AlarmManager 和 IntentService 的主题和文章，但我无法为我的应用程序聚在一起，是否有任何示例代码或其他东西？谢谢..

Answer 1

试试这个:

 /Create alarm manager

 AlarmManager mAlarmManger = (AlarmManager)getSystemService(Context.ALARM_SERVICE);

 //Create pending intent & register it to your alarm notifier class
 Intent intent = new Intent(this, AlarmReceiver_maandag_1e.class);
 intent.putExtra("uur", "1e"); // if you want
 PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

 //set timer you want alarm to work (here I have set it to 9.00)
 Calendar calendar = Calendar.getInstance();
 calendar.set(Calendar.HOUR_OF_DAY, 9);
 calendar.set(Calendar.MINUTE, 0);
 calendar.set(Calendar.SECOND, 0);

 //set that timer as a RTC Wakeup to alarm manager object
 mAlarmManger .set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
