我没有通过 getDescription() 方法得到完整的描述我错在哪里。？

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;
    }

    public boolean onOptionsItemSelected(MenuItem item){
        switch (item.getItemId()) {
        case 0:
            Log.i(tag,"Set RSS Feed");
            return true;
        case 1:
            Log.i(tag,"Refreshing RSS Feed");
            return true;
        }
        return false;
    }


    private void UpdateDisplay()
    {
        TextView feedtitle = (TextView) findViewById(R.id.feedtitle);
        TextView feedpubdate = (TextView) findViewById(R.id.feedpubdate);
        ListView itemlist = (ListView) findViewById(R.id.itemlist);


        if (feed == null)
        {
            feedtitle.setText("No RSS Feed Available");
            return;
        }

        feedtitle.setText(feed.getTitle());
        feedpubdate.setText(feed.getPubDate());

        ArrayAdapter<RSSItem> adapter = new ArrayAdapter<RSSItem>(this,android.R.layout.simple_list_item_1,feed.getAllItems());

        itemlist.setAdapter(adapter);

        itemlist.setOnItemClickListener(this);

        itemlist.setSelection(0);

    }


     public void onItemClick(AdapterView<?> parent, View v, int position, long id)
     {
         Log.i(tag,"item clicked! [" + feed.getItem(position).getTitle() + "]");

         Intent itemintent = new Intent(this,ShowDescription.class);

         Bundle b = new Bundle();
         b.putString("title", feed.getItem(position).getTitle());
         b.putString("description", feed.getItem(position).getDescription());
         b.putString("link", feed.getItem(position).getLink());
         b.putString("pubdate", feed.getItem(position).getPubDate());

         itemintent.putExtra("android.intent.extra.INTENT", b);

         startActivityForResult(itemintent,0);
     }
 }

Showdescription.xml 文件

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:autoLink="all"
    android:text="story goes here ...."
    android:id="@+id/storybox"
    />
<Button
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Back"
    android:id="@+id/back"
    />    

</LinearLayout>

我从 feedburners url 获得了这段代码的前两三行描述。所以这是我的这两个文件的代码，帮助我了解我应该进行哪些更改以获得完整描述。

您的 XML 全文有描述吗？一些 XML 仅提供摘要，您需要从博客管理属性面板启用完整文章。即使这种更改对 feedburner 也不起作用，请检查 feedburner 管理面板。
