推荐答案

要创建一个状态栏通知，这样在您的onCreate方法：

To create a status bar notification, do this in your onCreate Method:

1. 获取一个参考NotificationManager：

1. Get a reference to the NotificationManager:

  String ns = Context.NOTIFICATION_SERVICE;
  NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

实例化的通知：

Instantiate the Notification:

  int icon = R.drawable.notification_icon;
  CharSequence tickerText = "Hello";
  long when = System.currentTimeMillis();

  Notification notification = new Notification(icon, tickerText, when);

定义通知的扩展信息和意图：

Define the Notification's expanded message and Intent:

  Context context = getApplicationContext();
  CharSequence contentTitle = "My notification";
  CharSequence contentText = "Hello World!";
  Intent notificationIntent = new Intent(this, MyClass.class);
  PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

  notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

通过通知到NotificationManager：

Pass the Notification to the NotificationManager:

  private static final int HELLO_ID = 1;

  mNotificationManager.notify(HELLO_ID, notification);

就是这样。您的用户现在已经收到通知。

That's it. Your user has now been notified.
