1.动态设置padding，拿ImageView为例：

ImageView imageView = new ImageView(Context context);
imageView.setPadding(left,top,right,bottom);

拿LinearLayout里边放ImageVIew例

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(20, 20);
params.setMargins(20, 0, 20, 0);
imageView.setLayoutParams(params);

 1、DedeCMS顶级栏目启用二级域名，参考以下2篇文章，在此不作赘述。

DedeCMS栏目二级域名设置教程：http://www.d8zhan.com/dedecms/2614.html

IIS服务器下做301永久重定向设置方法：http://www.d8zhan.com/db/php_bc/7945.html

2、启用二级域名后，有朋友发现原网址、二级域名都可以访问同一篇文章，如www.d8zhan.com/help/caiji/2543.html和help.d8zhan.com/caiji/2543.html，www.d8zhan.com/help/caiji/2543.html并没有自动跳转到 help.d8zhan.com/caiji/2543.html。

这时，我们可以在iis6里对目录help做下重定向，方法如下：右键“help”，选择“属性”->“目录”，然后设置重定向到URL：http://help.d8zhan.com$s$q，然后选择下面1、3两项，保存即可。
