如何在android中的片段中创建通知

我正在尝试在片段中创建通知。我有错误。能帮忙吗

这是我的密码

NotificationManager notification = (Notification) getSystemService(getActivity().NOTIFICATION_SERVICE);
int icon = R.drawable.ic_launcher;
CharSequence tickerText = "your daily tip";
long when System.currentTimeMillis();
Context context = getActivity();
CharSequence contentTitle = "AutoKit";
CharSequence = contentText = "hi";
Intent notificationIntent = new Intent();
PendingIntent contentIntent = PendingIntent.getActivity(getActivity(), 0, notificationIntent, 0);
Notification notification = new Notification(icon, tickerText, when);
notification.setLatestEventInfo(context, contextTitle, contentText, contentIntent);
notificationManager.notify(1, notification);

错误在第一行。

用这一行更改您的第一行，应该做到以下几点：

NotificationManager notification = ( NotificationManager ) getActivity().getSystemService( getActivity().NOTIFICATION_SERVICE );
