报警接收器类

public class AlarmReceiver extends BroadcastReceiver {

private static final int MY_NOTIFICATION_ID = 1;
private NotificationManager notificationManager;
private Notification myNotification;

// Context ctx = this;

@SuppressWarnings("deprecation")
@Override
public void onReceive(Context context, Intent intent) {
    try {
        NotificationManager mNM;
        mNM = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(
                R.drawable.ic_launcher, "Pixitch Notification !",
                System.currentTimeMillis());
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
                new Intent(context, AlarmManage.class), 0);
        // Set the info for the views that show in the notification panel.
        notification.setLatestEventInfo(context, "Pixitch Notification!",
                "Reminder For TakePhoto", contentIntent);
        mNM.notify(0, notification);
    } catch (Exception e) {
        Toast.makeText(
                context,
                "There was an error somewhere, but we still received an alarm",
                Toast.LENGTH_SHORT).show();
        e.printStackTrace();

    }
}

}

tmemills 的价值是 278,088

tmemills 大约需要 4.5 分钟，但

警报管理器正在立即运行

我无法找到问题所在，因为我是 Android 的初学者。请帮我

尝试这个：

am.setRepeating(AlarmManager.RTC_WAKEUP, tmemills + System.currentTimeMillis(), 
     AlarmManager.INTERVAL_DAY, sender);

摆脱tmemills. 用作调用 oncal_alarm.getTimeInMillis()的第二个参数，因为这是自您希望事件发生的 Unix 纪元以来的毫秒数。set()AlarmManager
