Java 从URL获取并显示一系列图像

我正试图找到你，从这个链接

www.repubblica.it/rss/tecnologia/rss2.0.xml

中显示一组图像的方法是什么。我必须在我的RSS应用程序中显示它们，但我一直坚持这个论点。 图像位于该标签中（例如）。 你能帮助我吗？感谢您的帮助。 这是我的

处理程序

：

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 {
 // TODO Auto-generated method stub
 }

 @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;
 }
 else if (localName.equalsIgnoreCase("title")){
 currentState = state_title;
 }
 else if (localName.equalsIgnoreCase("psi")){
 currentState = state_description;
 }
 else if (localName.equalsIgnoreCase("link")){
 currentState = state_link;
 }
 else if (localName.equalsIgnoreCase("pubdate")){
 currentState = state_pubdate;
 }
 else{
 currentState = state_unknown;
 }

 }

 @Override
 public void endElement(String uri, String localName, String qName)
 throws SAXException {
 // TODO Auto-generated method stub
 if (localName.equalsIgnoreCase("item")){
 feed.addItem(item);
 }
 }

  @Override
  public void characters(char[] ch, int start, int length)
  throws SAXException {
  // TODO Auto-generated method stub

  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);
  break;
 case state_description:
 item.setDescription(strCharacters);
 break;
 case state_link:
 item.setLink(strCharacters);
 break;
 case state_pubdate:
 item.setPubdate(strCharacters);
 break;
 default:
 break;
 }
 }
 else{
 // not "item" tag found, it's feed's parameter
 switch(currentState){
 case state_title:
 feed.setTitle(strCharacters);
 break;
 case state_description:
 feed.setDescription(strCharacters);
 break;
 case state_link:
 feed.setLink(strCharacters);
 break;
 case state_pubdate:
 feed.setPubdate(strCharacters);
 break;
 default:
  break;
 }
 }

  currentState = state_unknown;
 }
 }

请尝试以下代码：

用这种方法

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

添加此代码将从元素返回url：

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

if（“enclosure”.equals（qName））{
对于（int i=0；i

反馈给我

以及如何显示它们？我是否必须添加最终的int state_enclosure，并在public vois chatacter（）方法中添加以下内容：case state_enclosure:item.setEnclosure（strCharacters）；break；；case state_title:feed.setTitle（strCharacters）；break；如果您只需要不需要实现chatacter（）的url，您将从startElement方法中的url获取值，您需要将其保存在数组中，解析后下载它们，然后您可以在视图中显示它们，state_enclosure是什么意思？没有什么，我很困惑。因此，要在我的ArrayAdapter中显示它们，这段代码很好？请尝试{url url url=new url（“what's here？”）；HttpGet-httpRequest=null；httpRequest=new-HttpGet（url.tori（））；HttpClient-HttpClient=new-DefaultHttpClient（）；HttpResponse-response=（HttpResponse）HttpClient.execute（httpRequest）；HttpEntity-entity=response.getEntity（）；BufferedHttpEntity-b_-entity=new-BufferedHttpEntity（entity）；InputStream input=b_entity.getContent（）；Bitmap Bitmap=BitmapFactory.decodeStream（输入）；img.setImageBitmap（位图）；}catch（异常示例）{}上面的代码将自动获取url，然后您需要下载它们尝试此示例从url下载图像
