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NotificationnotificationManager.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NotificationnotificationManager.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
