Android Alarm Manager的开始时间

Question

我有此代码，但“警报”不会从时间开始开始。 我希望myReceiver从分钟的开头开始，并且也从时间的开头开始重复。 我该如何实现？

PendingIntent pendingIntent3;
AlarmManager manager =(AlarmManager) getSystemService(Context.ALARM_SERVICE);


Intent alarmIntent3 = new Intent(getBaseContext(), myReceiver.class);
pendingIntent3 = PendingIntent.getBroadcast(getBaseContext(), 0, alarmIntent3, 0);


manager.setRepeating(AlarmManager.ELAPSED_REALTIME  _WAKEUP,
                SystemClock.currentThreadTimeMillis(),
                1*60*1000, pendingIntent3);

Answer 1

使用以下代码设置重复警报：

Intent alarmIntent3 = new Intent(getBaseContext(), myReceiver.class);
PendingIntent pendingIntent3 = PendingIntent.getBroadcast(getBaseContext(), 0, alarmIntent3, PendingIntent.FLAG_UPDATE_CURRENT);

// Current time
Calendar calendarNotifiedTime = Calendar.getInstance();
calendarNotifiedTime.setTimeInMillis(System.currentTimeMillis());
calendarNotifiedTime.set(Calendar.SECOND, 0);

// Set alarm
AlarmManager manager =(AlarmManager) getSystemService(Context.ALARM_SERVICE);
manager.setRepeating(AlarmManager.RTC_WAKEUP, calendarNotifiedTime.getTimeInMillis(), 1*60*1000, pendingIntent3);

确保已在AndroidManifest.xml声明了myReceiver BroadcastReceiver。
