运行通知取决于用户输入

Question

我想在android上运行通知取决于用户插入的日期和时间 我知道如何从活动开始通知，但我认为这不是我想要的， 任何人都可以帮我一些代码吗？

以下是您如何实现这一目标，您必须在用户选择的特定时间添加闹钟

public class TimerReceiverSyncInterval extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

    Log.d("TAG", "Sync OnReceive--");



    scheduleAlarms(context);
    context.startService(new Intent(context, NotificationServiceSyncInterval.class));

}

public static void scheduleAlarms(Context paramContext) {

    Calendar calendar = Calendar.getInstance();

    String[] splited = Utility.mPrefs.getSyncTime().split("\\s+");
    if (Utility.mPrefs.getSyncTime().contains("Minute")) {

        calendar.set(Calendar.MINUTE, Integer.parseInt(splited[0]));
    } else if (Utility.mPrefs.getSyncTime().contains("Hour")) {
        calendar.set(Calendar.HOUR, Integer.parseInt(splited[0]));
    }

    AlarmManager localAlarmManager = (AlarmManager) paramContext.getSystemService(Context.ALARM_SERVICE);
    PendingIntent localPendingIntent = PendingIntent.getService(paramContext, 0,
            new Intent(paramContext, NotificationServiceSyncInterval.class), PendingIntent.FLAG_UPDATE_CURRENT);

    if (Utility.mPrefs.getSyncTime().contains("Minute")) {

        localAlarmManager.setRepeating(AlarmManager.RTC, calendar.getTimeInMillis(),
                Integer.parseInt(splited[0]) * (60 * 1000), localPendingIntent);

    } else if (Utility.mPrefs.getSyncTime().contains("Hour")) {

        localAlarmManager.setRepeating(AlarmManager.RTC, calendar.getTimeInMillis(),
                Integer.parseInt(splited[0]) * (60 * 60 * 1000), localPendingIntent);

    }


}

}

用于处理/呼叫通知

public class NotificationServiceSyncInterval extends IntentService {

public NotificationServiceSyncInterval() {
    super("Sync Tracker Online");

}

public NotificationServiceSyncInterval(String paramString) {
    super(paramString);

}

@Override
protected void onHandleIntent(Intent intent) {
    Log.d("TAG", "Sync Handler call");
        callNotification();

}

public static void callNotification() {
    //Notification code
}
}
