api 11 版本之前：

//显示通知信息  
        protected void showNotification() {  
            NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);  
    //              Notification notification = new Notification(this,R.drawable.ic_launcher);  
            Notification notification = new Notification(R.drawable.ic_launcher,"",System.currentTimeMillis() );  
            PendingIntent contentIndent = PendingIntent.getActivity(MainActivity.this, 0, new Intent(MainActivity.this,MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);  
            notification.setLatestEventInfo(MainActivity.this, "您的BMI值过高", "通知监督人", contentIndent);  
            //加i是为了显示多条Notification  
            notificationManager.notify(i,notification);  
            i++;  
        }

api版本之后：

protected void showNotification2() {  
            NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);  
            Builder builder = new Notification.Builder(MainActivity.this);  
            PendingIntent contentIndent = PendingIntent.getActivity(MainActivity.this, 0, new Intent(MainActivity.this,MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);  
            builder . setContentIntent(contentIndent) .setSmallIcon(R.drawable.ic_launcher)//设置状态栏里面的图标（小图标） 　　　　　　　　　　　　　　　　　　　　.setLargeIcon(BitmapFactory.decodeResource(res, R.drawable.i5))//下拉下拉列表里面的图标（大图标） 　　　　　　　.setTicker("this is bitch!") //设置状态栏的显示的信息  
                   .setWhen(System.currentTimeMillis())//设置时间发生时间  
                   .setAutoCancel(true)//设置可以清除  
                   .setContentTitle("This is ContentTitle")//设置下拉列表里的标题  
                   .setContentText("this is ContentText");//设置上下文内容  
            Notification notification = builder.getNotification();  
            //加i是为了显示多条Notification  
            notificationManager.notify(i,notification);  
        }

但是如果你的minsdk版本是8的话，毕竟这个是大多数，那么只好选择就版本了，虽然ide会提示此方法已删除
