不显示Android的通知

我正在尝试在设定的时间段后使用以下命令发出通知：

scheduleNotification(getNotification("Notification content..") differ);

以及以下功能-

private Notification getNotification(String content) {
        Notification.Builder builder = new Notification.Builder(this);
        builder.setContentTitle("Scheduled Notification");
        builder.setContentText(content);
        builder.setSmallIcon(R.drawable.icon);

        return builder.build();
}


private void scheduleNotification(Notification notification, long delay) {

        Intent notificationIntent = new Intent(this, NotificationPublisher.class);
            notificationIntent.putExtra(NotificationPublisher.NOTIFICATION_ID, 1);
        notificationIntent.putExtra(NotificationPublisher.NOTIFICATION, notification);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);        
        long futureInMillis = SystemClock.elapsedRealtime() + delay;
        AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
        alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, futureInMillis, pendingIntent);
}

记录延迟值后，我得到57580，大约57秒，但即使在这段时间之后，我在状态栏上也没有收到任何通知

请帮助。

您需要一个

广播接收器

从系统获取通知

public static class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        getNotification(String content);
    }        
}

记住在AndroidManifest中声明类：

<receiver android:name=".AlarmReceiver" />

你应该用一个广播接收器来做这个把戏。在onReceive（）中安排报警和启动通知。。。。。
