本地通知不重复 [英] local notification not repeating

问题描述

我需要向用户显示每2小时完成一次注册的通知，我将其设置为几分钟，以便进行测试，但是我的通知只有在不再发送时才会出现. 请提出建议.

I need to show notification for completing registration to user in every 2 hrs , I have set it to few mins for testing , but my notification comes only once it never come again . Please suggest.

我的重复任务代码:

public void createNotification() {
    Intent notificationIntent = new Intent(context, ShowNotification.class);
    PendingIntent contentIntent = PendingIntent.getService(context, 0, notificationIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    //  am.cancel(contentIntent);

    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.add(Calendar.SECOND, 60); // first time
    long frequency= 60 * 1000; // in ms

    am.setRepeating(AlarmManager.RTC,  calendar.getTimeInMillis(), frequency, contentIntent);


}

我的代码在使用中:

public class ShowNotification extends Service {

private final static String TAG = "ShowNotification";

@Override
public void onCreate() {
    super.onCreate();

   Intent mainIntent = new Intent(this, DashBoardActivity.class);

    NotificationManager notificationManager
            = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

    Notification noti = new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentIntent(PendingIntent.getActivity(this, 0, mainIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT))
            .setContentTitle("HELLO " + System.currentTimeMillis())
            .setContentText("Please complete all the steps for registration")
            .setDefaults(Notification.DEFAULT_ALL)
            .setSmallIcon(R.drawable.ic_launcher)
            .setTicker("ticker message")
            .setWhen(System.currentTimeMillis())
            .build();

    notificationManager.notify((int) System.currentTimeMillis(), noti);
   // ToastUtil.displayToast(this , "my msg");
    Log.i(TAG, "Notification created");
}

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

}

推荐答案

您需要覆盖Service的onStartCommand并将onCreate的代码移到那里.如下所示

You need to override onStartCommand of Service and Move your code of onCreate there. Like below

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    // And move all codes of onCreate here


Intent mainIntent = new Intent(this, DashBoardActivity.class);

NotificationManager notificationManager
        = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

Notification noti = new NotificationCompat.Builder(this)
        .setAutoCancel(true)
        .setContentIntent(PendingIntent.getActivity(this, 0, mainIntent,
                PendingIntent.FLAG_UPDATE_CURRENT))
        .setContentTitle("HELLO " + System.currentTimeMillis())
        .setContentText("Please complete all the steps for registration")
        .setDefaults(Notification.DEFAULT_ALL)
        .setSmallIcon(R.drawable.ic_launcher)
        .setTicker("ticker message")
        .setWhen(System.currentTimeMillis())
        .build();

notificationManager.notify((int) System.currentTimeMillis(), noti);
// ToastUtil.displayToast(this , "my msg");
Log.i(TAG, "Notification created");



    // We want this service to continue running until it is explicitly
    // stopped, so return sticky.
    return START_STICKY;
}
