Android 警报管理器开始时间

Question

我有这段代码，但闹钟不会从时间开始。我希望 myReceiver 从 start of minutes 开始并从 start of times 开始重复。我怎样才能做到这一点？

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闹钟：

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);

确保您已经在 AndroidManifest.xml 中声明了 myReceiver BroadcastReceiver。
