好的，这对我有用..

static  String getImageFromFeed(String _HtmlString) {

    Pattern p=null;
    Matcher m= null;
    String sUrl ="";



    try {

         p= Pattern.compile("src='(.*?)'");
         m= p.matcher(_HtmlString);

    } catch (Exception e) {
        sUrl = e.toString();
    }

    if  (m.find())
         {
          sUrl=m.group(1);

         }

    return sUrl;
}
