MyAdapter

从网上参考了一些资料，发现android的SimpleAdapter在ListActivity中使用时，只能加载drawable中的图片，不能加载网络图片

参考了别人写的资料，重写了以下SimpleAdapter的setViewImage(ImageView v, String value)方法

主要参考：http://android.group.iteye.com/group/blog/616262，特此鸣谢！！！

/**********************************************************
* 自己写的Adapter，继承SimpleAdapter，使其可以加载网络图片资源，哇嘎嘎
