    copied!<p>This ids:</p> <pre><code>android:id="@+id/android:list1" android:id="@android:id/list1" </code></pre> <p>don't exist in the SDK. The id <code>android:id="@+id/list1"</code> is valid and if you use <code>findViewById(R.id.list1)</code> in the <code>Activity</code>(which has as its content the layout with the two <code>ListViews</code>) you'll find the <code>ListView</code>.</p> <p>Also, as your code suggests it appears you're trying to manipulate the two <code>ListViews</code> as one which would be plain wrong. In the <code>onPostExecute()</code> method you'll use the <code>setListAdapter()</code> method to set the adapter for the <code>ListView</code> with the id <code>android.R.id.list</code> and for the other <code>ListView</code> you'll do:</p> <pre><code>ListView second = (ListView) findViewById(R.id.list1); // set the adapter for this ListView </code></pre> <p>Regarding this code:</p> <pre><code> Uri feedUri = Uri.parse(myRssFeed.getItem(position).getLink()); Uri feedUri1 = Uri.parse(myRssFeed1.getItem(position).getLink()); Intent myIntent = new Intent(Intent.ACTION_VIEW, feedUri); Intent myIntent1 = new Intent(Intent.ACTION_VIEW, feedUri1); startActivity(myIntent); startActivity(myIntent1); </code></pre> <p>what are you trying to do starting two(?!?!) activities(to do what?!)?</p> <p>Edit:</p> <pre><code>try { URL rssUrl = new URL("http:/news.rss"); SAXParserFactory mySAXParserFactory = SAXParserFactory.newInstance(); SAXParser mySAXParser = mySAXParserFactory.newSAXParser(); XMLReader myXMLReader = mySAXParser.getXMLReader(); RSSHandler myRSSHandler = new RSSHandler(); myXMLReader.setContentHandler(myRSSHandler); InputSource myInputSource = new InputSource(rssUrl.openStream()); myXMLReader.parse(myInputSource); myRssFeed = myRSSHandler.getFeed(); RSSHandler myRSSHandler1 = new RSSHandler(); myXMLReader.setContentHandler(myRSSHandler1); URL rssUrl1 = new URL("http://events.rss"); InputSource myInputSource1 = new InputSource(rssUrl1.openStream()); myXMLReader.parse(myInputSource1); myRssFeed1 = myRSSHandler1.getFeed(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (ParserConfigurationException e) { e.printStackTrace(); } catch (SAXException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } @Override protected void onPostExecute(Void result) { if (myRssFeed!=null &amp;&amp; myRssFeed1!=null) { ArrayAdapter&lt;RSSItem&gt; adapter = new ArrayAdapter&lt;RSSItem&gt;(getApplicationContext(), android.R.layout.simple_list_item_1, myRssFeed.getList()); setListAdapter(adapter); ArrayAdapter&lt;RSSItem&gt; adapter1 = new ArrayAdapter&lt;RSSItem&gt;(getApplicationContext(), android.R.layout.simple_list_item_1,myRssFeed1.getList()); ListView lv = (ListView) findViewById(R.id.list1); lv.setAdapter(adapter1); } else { setListAdapter(new ArrayAdapter&lt;RSSItem&gt;(getApplicationContext(), android.R.layout.simple_list_item_1, new ArrayList&lt;RSSItem&gt;());); ArrayAdapter&lt;RSSItem&gt; adapterEmpty1 = new ArrayAdapter&lt;RSSItem&gt;(getApplicationContext(), android.R.layout.simple_list_item_1, new ArrayList&lt;RSSItem&gt;()); ListView lv = (ListView) findViewById(R.id.list1); lv.setAdapter(adapterEmpty1); } } </code></pre>
