Question

我正在开发警报应用程序，我需要在所有日子里同时重复调用警报。我正在使用代码来调用警报，

c = Calendar.getInstance();

    c.set(Calendar.HOUR_OF_DAY,10);
    c.set(Calendar.MINUTE, 0);
    c.set(Calendar.SECOND, 0);
    c.set(Calendar.MILLISECOND, 0);

Intent intent = new Intent(HomeActivity.this, MyAlarmService.class);
            PendingIntent pendingIntent = PendingIntent.getService(HomeActivity.this, 123123, intent, 0);
            alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
            alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, c.getTimeInMillis(), (24*60*60*1000), pendingIntent);

通过使用此代码，我只在上午10点调用当天，而不是所有日子。还有另一种方法吗？

Answer 1

更新时间，每隔5分钟响铃：

Intent intent = new Intent(this, this.getClass());
PendingIntent pendingIntent =
    PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

long currentTimeMillis = System.currentTimeMillis();
long nextUpdateTimeMillis = currentTimeMillis + 5 * DateUtils.MINUTE_IN_MILLIS;
Time nextUpdateTime = new Time();
nextUpdateTime.set(nextUpdateTimeMillis);

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
   alarmManager.set(AlarmManager.RTC, nextUpdateTimeMillis, pendingIntent);

设置闹钟每天工作时间（例如，上午8点至晚上18点）

// if not the time to ring, set to the next day
if (nextUpdateTime.hour < 8 || nextUpdateTime.hour >= 18)
{
    nextUpdateTime.hour = 8;
    nextUpdateTime.minute = 0;
    nextUpdateTime.second = 0;
    nextUpdateTimeMillis = nextUpdateTime.toMillis(false) + DateUtils.DAY_IN_MILLIS;
}
else{
    // call your alarm
}

在班级MyAlarmService中，当闹钟开启时，请重置闹钟。在设置闹钟时，您甚至可以在意图中发送MyAlarmService的值（可能是为了停止闹钟）

如何使用Android中的警报管理器每天获得重复警报？
