在数据库中重复时间和周日，在手表和手机上打开Android通知

Question

我正在开发一个应用程序，它允许我在智能手机或智能手表（安卓服装）上显示通知。通过保存特定时间（timepicker），描述（edittext）和工作日（切换按钮），数据将保存到数据库中。

我的问题是在正确的时间显示正确的通知，这是在之前创建的。保存到数据库工作，但在正确的时间显示通知不起作用。我多次尝试使用AlarmManager解决方案。但我不太确定如何使用它。 我的数据库看起来像：

public static final String KEY_ID_ACTION = "id";
public static final String KEY_DESCRIPTION = "description";
public static final String KEY_HOUR = "time_hour";
public static final String KEY_MINUTE = "time_minute";
public static final String KEY_MONDAY = "monday";
public static final String KEY_TUESDAY = "tuesday";
public static final String KEY_WEDNESDAY = "wednesday";
public static final String KEY_THURSDAY = "thursday";
public static final String KEY_FRIDAY = "friday";
public static final String KEY_SATURDAY = "saturday";
public static final String KEY_SUNDAY = "sunday";

我的AlarmManagerBroadcastReceiver看起来像这样：

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver {
final public static String ONE_TIME = "onetime";
DatabaseHandler db;

@Override
public void onReceive(Context context, Intent intent) {
    db = new DatabaseHandler(context);

    PowerManager pm = (PowerManager) context
            .getSystemService(Context.POWER_SERVICE);
    PowerManager.WakeLock wl = pm.newWakeLock(
            PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG");
    // Acquire the lock
    wl.acquire();

    // You can do the processing here.
    Bundle extras = intent.getExtras();
    StringBuilder msgStr = new StringBuilder();

    if (extras != null && extras.getBoolean(ONE_TIME, Boolean.FALSE)) {
        // Make sure this intent has been sent by the one-time timer button.
        msgStr.append("One time Timer : ");
    }
    Format formatter = new SimpleDateFormat("hh:mm:ss a");
    msgStr.append(formatter.format(new Date()));

    Toast.makeText(context, msgStr, Toast.LENGTH_LONG).show();

    // Release the lock
    wl.release();
}

public void SetAlarm(Context context, String hour, String minute) {
    AlarmManager am = (AlarmManager) context
            .getSystemService(Context.ALARM_SERVICE);
    Calendar cal = Calendar.getInstance(Locale.GERMAN);
    cal.set(Calendar.HOUR, Integer.valueOf(hour));
    cal.set(Calendar.MINUTE, Integer.valueOf(minute));
    cal.set(Calendar.SECOND, 0);
    //cal.set(Calendar.DAY_OF_WEEK, 1);
    cal.set(Calendar.DAY_OF_WEEK, 3);

    Long alarmTime = cal.getTimeInMillis();

    Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);
    intent.putExtra(ONE_TIME, Boolean.FALSE);
    PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);

    // After after 5 seconds
    am.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime,
            1000 * 5, pi);
}

public void CancelAlarm(Context context) {
    Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);
    PendingIntent sender = PendingIntent
            .getBroadcast(context, 0, intent, 0);
    AlarmManager alarmManager = (AlarmManager) context
            .getSystemService(Context.ALARM_SERVICE);
    alarmManager.cancel(sender);
}

public void setOnetimeTimer(Context context) {
    AlarmManager am = (AlarmManager) context
            .getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);
    intent.putExtra(ONE_TIME, Boolean.TRUE);
    PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
    am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), pi);
}
}

使用以下代码，我可以设置闹钟，并且还会显示祝酒词。

public void onetimeTimer(View view) {
    Context context = getActivity().getApplicationContext();
    if (alarm != null) {
        alarm.setOnetimeTimer(context);
    } else {
        Toast.makeText(context, "Alarm is null", Toast.LENGTH_SHORT).show();
    }
}

此外，工作日的使用已经有效，但只能创建一个通知，甚至不会从数据库中获取数据，也不会每周重复一次通知。我从数据库中删除通知后，不知道如何停止通知的警报。
