我沒有通過getDescription()方法得到完整的描述,我錯在哪裏?RSS閱讀器沒有得到完整描述
RSSReader.java
public class RSSReader extends Activity implements OnItemClickListener
{
public final String RSSFEEDOFCHOICE = "someurloffeedburner?format=xml";
public final String tag = "RSSReader";
private RSSFeed feed = null;
/** Called when the activity is first created. */
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
// go get our feed!
feed = getFeed(RSSFEEDOFCHOICE);
// display UI
UpdateDisplay();
}
private RSSFeed getFeed(String urlToRssFeed)
{
try
{
// setup the url
URL url = new URL(urlToRssFeed);
// create the factory
SAXParserFactory factory = SAXParserFactory.newInstance();
// create a parser
SAXParser parser = factory.newSAXParser();
// create the reader (scanner)
XMLReader xmlreader = parser.getXMLReader();
// instantiate our handler
RSSHandler theRssHandler = new RSSHandler();
// assign our handler
xmlreader.setContentHandler(theRssHandler);
// get our data via the url class
InputSource is = new InputSource(url.openStream());
// perform the synchronous parse
xmlreader.parse(is);
// get the results - should be a fully populated RSSFeed instance, or null on error
return theRssHandler.getFeed();
}
catch (Exception ee)
{
// if we have a problem, simply return null
return null;
}
}
public boolean onCreateOptionsMenu(Menu menu)
{
super.onCreateOptionsMenu(menu);
menu.add(0,0,0, "Choose RSS Feed");
menu.add(0, 1, 1, "Refresh");
Log.i(tag,"onCreateOptionsMenu");
return true;

我越來越描述第1二,三線由feedburners網址驗證碼。所以這是我的這兩個文件的代碼幫助我瞭解我應該做些什麼修改才能得到完整的描述。
你是對的我有我的XML文件的問題。感謝答覆。 – tejas178
