Actually i try to do xml parsing from my local host and retrieve the value into the spinner.
what my doubt is i also need to retrieve the value inside the attribute which was present inside the book node (i,e) . I refer many tutorials and source codes still i cant able to do it. Any one please help to do it. Thanks in advance.

android xml parsing does not show results?

I am newbie to android, I am trying to parse xml data from http://www.astrology.com/horoscopes/daily-horoscope.rss, I grab the code from
How can I parse xml from url in android? here, I used sherLock library, I also set internet permissions in manifest, but still unable to grab it, here is the same code except a little modification,
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/* Create a new layout to display the view */
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(1);
/* Create a new textview array to display the results */
TextView name[];
//TextView website[];
//TextView category[];
try {
URL url = new URL("http://www.astrology.com/horoscopes/daily-horoscope.rss");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(url.openStream()));
doc.getDocumentElement().normalize();
NodeList nodeList = doc.getElementsByTagName("item");
/** Assign textview array lenght by arraylist size */
name = new TextView[nodeList.getLength()];
// website = new TextView[nodeList.getLength()];
//category = new TextView[nodeList.getLength()];
for (int i = 0; i < nodeList.getLength(); i++) {
Node node = nodeList.item(i);
name[i] = new TextView(this);
//website[i] = new TextView(this);
//category[i] = new TextView(this);
Element fstElmnt = (Element) node;
NodeList nameList = ((Document) fstElmnt).getElementsByTagName("title");
Element nameElement = (Element) nameList.item(0);
nameList = ((Node) nameElement).getChildNodes();
name[i].setText("Name = " + ((Node) nameList.item(0)).getNodeValue());
//category[i].setText("Website Category = " + ((org.w3c.dom.Element) websiteElement).getAttribute("category"));
layout.addView(name[i]);
//layout.addView(website[i]);
//layout.addView(category[i]);
}
} catch (Exception e) {
System.out.println("XML Pasing Excpetion = " + e);
}
/** Set the layout view to display */
setContentView(layout);
}
Remember I am extending my MainActivity class from SherlockActivity, when I execute the code, only action bar appears!

How to tackle the delay in loading an activity?

I have made changes to my code, as I have given this.setContentView(sv); right at the beginning of onCreate(), but the view is loading only after executing try catch it seems. Is it really possible to show the view before executing try catch?

After analyzing your onCreate(), it is obvious that your Activity would take a while to show. All of your UI is designed and added dynamically and must (according to your code) wait for the data to load and be parsed and organized. In other words, you are blocking your UI with your data processing.
Consider moving your data loading to an AsyncTask. Also consider designing/loading your UI before the data. This would allow your user to see something, even if its not complete. And you can always add Views or change the display properties after the onCreate(). It will also get reduce the perception of the UI lag.

As the others have said move your work into an AsyncTask so that it's not blocking main thread. If you're interested in seeing exactly what's taking all the time then I'd suggest taking some time to read up on TraceView - it's a great tool for profiling.

suggestion move big try block to another thread, don't block the ui.

Can't parse XML with DOM in android

I am having some trouble parsing XML in Android from an URL. I don't know if it's the XML parsing that's the problem or only when I am trying to show it on the screen because
setListAdapter(new ArrayAdapter<String>(ANDROIDXMLActivity.this, android.R.layout.simple_list_item_1, stopNumbers));
wont show anything. The code below works perfectly in a java program.

Solved it. I had forgot to add internet permission in the manifest.
