Android 闹钟管理器开始时间

Question

我有这段代码，但闹钟不会从一开始就开始。我希望myReceiver 从分钟开始，并从时间开始重复。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报警：

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);

确保您在AndroidManifest.xml 中声明了myReceiver BroadcastReceiver。
