URL에서 이미지 시퀀스 가져 오기 및 표시

Question

나는이 링크 www.repubblica.it/rss/tecnologia/rss2.0.xml에서 일련의 이미지를 표시하는 방법을 찾으려고합니다. 내 RSS 애플 리케이션에서 그들을 보여 줘야하지만이 인수에 붙어 있어요. 이미지는이 태그 <enclosure url="http://www.repstatic.it/content/nazionale/img/2014/02/06/201914230-3e1f0f4a-c5e4-413a-acd0-f15b781438eb.jpg" length="24317" type="image/jpeg"/>에 있습니다 (예 :). 도와 주시겠습니까? 어떤 도움을 주셔서 감사합니다. 이 내 Handler :

if ("enclosure".equals(qName)) { 
     for (int i = 0; i < attributes.getLength(); i++) 
      if (attributes.getQName(i).equals("url")) 
       String url = attributes.getValue(i); 

피드 : 요소에서 URL을 반환이 코드를 추가하려면이 방법

public void startElement(String uri, String localName, String qName,Attributes attributes)
