Notification notification;

NotificationManager nMgr;//通知管理器

structure{

      nMgr=(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

}

function(){

     if(notification==null){
notification=new Notification();

}
notification.icon=R.drawable.ic_launcher;//左侧图片
notification.tickerText = "有新短消息了！";  
notification.when = System.currentTimeMillis();  
notification.setLatestEventInfo(this, "通知的消息title","消息内容", null); 
notification.number = 1;  //消息的数量
notification.flags |= Notification.FLAG_NO_CLEAR; // FLAG_AUTO_CANCEL表明当通知被用户点击时，通知将被清除。
nMgr.notify(1, notification);

}

notification.setLatestEventInfo方法中,需传contenxt,消息头,消息体与PendingIntent。PendingIntent为点击要跳转的activity。例如：

Intent i=new Intent(TestActivity1.this,TestActivity2.class);
PendingIntent it=PendingIntent.getActivity(getApplicationContext(), 0, i, 0);
