notification新旧用法

api10版本以前 
  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, "通知内容", "通知", contentIndent);  
       
        notificationManager.notify(id,notification);  
        
    } 
api10以后

protected void showNotification() {  
        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("通知!") //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("title")//设置下拉列表里的标题  
           .setContentText("contenttext");//设置上下文内容  
        Notification notification = builder.getNotification();  

        notificationManager.notify(id,notification);  
    }
