/** Called when the activity is first created. */

private static final int id=1;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Notification notification = new Notification(R.drawable.ic_launcher,"开始下载",System.currentTimeMillis());// 获得一个Notification对象
Intent intent = new Intent(this, NotificationActivity.class);// 这个是设置点击那个下拉框时，由那个进入到那个Activity
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);//获得系统的NotificationManager
PendingIntent contentintent=PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(this, "正在下载", "下载完成", contentintent);//下拉框时，listview上面的文字

manager.notify(id,notification);//使用或者激活这个Notificaiton
