我正在尝试将RSS源添加到我的Android应用程序中，我正在检索Feed，例如标题，描述和Feed的链接，但无法获取特定Feed的图像。
以下是我的DefaultXmlHandler类。请过去帮帮我。
public class XmlHandler extends DefaultHandler {
private RssFeedStructure feedStr = new RssFeedStructure();
private List<RssFeedStructure> rssList = new ArrayList<RssFeedStructure>();
private int articlesAdded = 0;
// Number of articles to download
private static final int ARTICLES_LIMIT = 15;
StringBuffer chars = new StringBuffer();
public void startElement(String uri, String localName, String qName, Attributes atts) {
chars = new StringBuffer();
if (qName.equalsIgnoreCase("media:content"))
{
if(!atts.getValue("url").toString().equalsIgnoreCase("null")){
feedStr.setImgLink(atts.getValue("url").toString());
}
else{
feedStr.setImgLink("");
}
}
}
public void endElement(String uri, String localName, String qName) throws SAXException {
if (localName.equalsIgnoreCase("title"))
{
feedStr.setTitle(chars.toString());
}
else if (localName.equalsIgnoreCase("description"))
{
feedStr.setDescription(chars.toString());
}
else if (localName.equalsIgnoreCase("pubDate"))
{
feedStr.setPubDate(chars.toString());
}
else if (localName.equalsIgnoreCase("encoded"))
{
feedStr.setEncodedContent(chars.toString());
}
else if (qName.equalsIgnoreCase("media:content"))
{
}
else if (localName.equalsIgnoreCase("link"))
{
try {
feedStr.setUrl(new URL(chars.toString()));
}catch (Exception e){}
}
if (localName.equalsIgnoreCase("item")) {
rssList.add(feedStr);
feedStr = new RssFeedStructure();
articlesAdded++;
if (articlesAdded >= ARTICLES_LIMIT)
{
throw new SAXException();
}
}
}
public void characters(char ch[], int start, int length) {
chars.append(new String(ch, start, length));
}
public List<RssFeedStructure> getLatestArticles(String feedUrl) {
URL url = null;
try {
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
url = new URL(feedUrl);
xr.setContentHandler(this);
xr.parse(new InputSource(url.openStream()));
} catch (IOException e) {
} catch (SAXException e) {
} catch (ParserConfigurationException e) {
}
return rssList;
}
}
