java - Android 每日通知在错误的时间多次显示

Question

我正在尝试让 Android 通知在每天中午出现。每当设备启动时，通知似乎都会显示一次，然后偶尔会出现一次。

这是我的服务:

public class myService extends Service {
public static final String TAG = "LocationLoggerServiceManager";
@Override
public void onCreate() {
    // TODO Auto-generated method stub
    super.onCreate();
    Log.v(TAG, "on onCreate");
}


@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, LoginActivity.class), 0);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("App name")
            .setContentText("Notification")
            .setContentIntent(contentIntent)
            .setDefaults(Notification.DEFAULT_SOUND)
            .setAutoCancel(true);
    NotificationManager mNotificationManager =
        (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify("main", 1, mBuilder.build());

    return super.onStartCommand(intent, flags, startId);
}

@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return null;
}
}

和接收者:

   public class MyBroadcastReceiver extends BroadcastReceiver {

public static final String TAG = "LocationLoggerServiceManager";
@Override
public void onReceive(Context context, Intent intent) {
    Log.d(TAG, "Broadcast Received");
    handleMessage(context, intent);
}


private void handleMessage(Context context, Intent intent)
{
    PendingIntent contentIntent = PendingIntent.getService(context, 0, new Intent(context, myService.class), 0);

    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    alarmManager.cancel(contentIntent);
    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, 12);
    calendar.set(Calendar.MINUTE, 00);
    calendar.set(Calendar.SECOND, 00);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24*60*60*1000 , contentIntent);
}
}

任何指示都值得赞赏。谢谢。

我尝试设置自己的通知/警报类。我发现管理它的唯一方法是扩展 Android 日历。

如果您想尝试这种方式，请参阅此链接作为开始:

我有一个这种方法的示例，但是我正在工作，如果您需要的话，我可以稍后提供我的代码!
