获取并显示来自网址

的一系列图像

我试图找到yout，从此链接显示一组图像的方式是www.repubblica.it/rss/tecnologia/rss2.0.xml。我必须在我的RSS应用程序中显示它们，但我坚持这一论点。图片在这个标签<enclosure url="http://www.repstatic.it/content/nazionale/img/2014/02/06/201914230-3e1f0f4a-c5e4-413a-acd0-f15b781438eb.jpg" length="24317" type="image/jpeg"/>（例如）。你能帮我吗？任何帮助表示赞赏。这是我Handler：获取并显示来自网址

public class RSSHandler extends DefaultHandler { 

final int state_unknown = 0; 
final int state_title = 1; 
final int state_description = 2; 
final int state_link = 3; 
final int state_pubdate = 4; 
int currentState = state_unknown; 

RSSFeed feed; 
RSSItem item; 

boolean itemFound = false; 

RSSHandler(){ 
} 

RSSFeed getFeed(){ 
return feed; 
} 

@Override 
public void startDocument() throws SAXException { 
// TODO Auto-generated method stub 
feed = new RSSFeed(); 
item = new RSSItem(); 

} 

@Override 
public void endDocument() throws SAXException {

@Override 
public void startElement(String uri, String localName, String qName, 
Attributes attributes) throws SAXException { 
// TODO Auto-generated method stub 

if (localName.equalsIgnoreCase("item")){ 
itemFound = true; 
item = new RSSItem(); 
currentState = state_unknown;

} 

@Override

    String strCharacters = new String(ch,start,length); 

    if (itemFound==true){ 
    // "item" tag found, it's item's parameter 
    switch(currentState){ 
    case state_title: 
    item.setTitle(strCharacters);

试试这个代码：在这个方法中

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

添加以下代码将从元素返回的网址：

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

关于如何展示他们？我必须添加 _final int state_enclosure_和_public vois chatacter（）_方法添加此： _case state_enclosure： item.setEnclosure（strCharacters）; break; _; case state_title： feed.setTitle（strCharacters）; 休息; – Pier

如果你只需要你不需要的URL实现chatacter（），你会从startElement方法中的url中获得值，你需要将它保存在数组中，解析后下载它们，你可以在你的视图中显示它们，你用state_enclosure表示什么？ –

没什么，我很困惑。那么为了在我的ArrayAdapter中展示它们，这代码很好吗？ – Pier
