Async task inside fragment starts to execute before opening its fragment

I am creating an app with tabs with fragment and swipable views ...
I have xml parser fragment which works in asynctask in background ..
The problem is that when i open the other fragment and not the xml parser fragment it starts the asynctask and shows progressbar dialog that keeps the user waiting till the task complete! How do i make it like that it will start the async task when i go to that xmlparser fragment only ? Can anybody help?
My code:

Unable to show values in listview on android/eclipse

"http://54.251.60.177/StudentWebService/StudentDetail.asmx"
The above link is the web service, which contains two methods namely
GetStudentDetails
GetStudentsDetailsXML
The input values for this method is "carrier" for both methods
I am trying to consume this web service from android by the method SOAP.Actually the second method service is returning the values in the form of XML,here i am trying to consume this method and trying to show that returned values into List-view.But after getting run of my emulator,its simply just showing a black screen.
How to achieve my requirements? Can any one make me clear.
Please find my sources for reference

Thanks in advance!..

After the line:
// selecting single ListView item
ListView lv = getListView();
if the adapter related to lv is adapter (a few lines above), I would put this way,though it works with ArrayAdapter and not ListAdapter:
lv.setAdapter(adapter);
then, you have to add elements to the adapter with adapter.add(what you add, which is a string if I'm not wrong according to the documentation),and when all is added add:
adapter.notifyDataSetChanged();
The last one is to make the elements to be shown on the screen

content:encoded XMLParser android

Ok, about this specific situation, I have large XML file that should be parsed and shown in Android, and the part of it is here:
.
.
<rss xmlns:content="http://purl.org/rss/1.0/modules/content/:
.
.
<item>
<title>RTS1</title>
<pubDate>Tue, 14, Aug 2012</pubDate>

<br>09:00 Kamiondzije .................. 23:15 Film<br>]]>
</content:encoded>
<item>
In my main, app I have done this:
public class Main extends ListActivity {
// All static variables
static final String URL = "http://tvprofil.net/rss/feed/channel-group-2.xml";
// XML node keys
static final String KEY_ITEM = "item"; // parent node
static final String KEY_NAME = "title";
static final String KEY_DATE = "pubDate";
static final String KEY_DESC = "content:encoded";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayList<HashMap<String,String>> menuItems = new ArrayList<HashMap<String,String>>();
XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(URL); //get XML
Document doc = parser.getDomElement(xml); // get DOM elem.
NodeList nl = doc.getElementsByTagName(KEY_ITEM);
//loop
for (int i=0; i< nl.getLength(); i++){
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element) nl.item(i);
//add to map
map.put(KEY_NAME, parser.getValue(e, KEY_NAME));
map.put(KEY_DATE, parser.getValue(e, KEY_DATE));
map.put(KEY_DESC, parser.getValue(e, KEY_DESC));
// hash => list
menuItems.add(map);
}
ListAdapter adapter = new SimpleAdapter(this, menuItems, R.layout.list_item,
new String[]{KEY_NAME, KEY_DESC, KEY_DATE}, new int[]{
R.id.name, R.id.description, R.id.date
});
setListAdapter(adapter);
//singleView
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
String name = ((TextView)view.findViewById(R.id.name)).getText().toString();
String date = ((TextView)view.findViewById(R.id.date)).getText().toString();
String description = ((TextView)view.findViewById(R.id.description)).getText().toString();
//intent
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra(KEY_NAME, name);
in.putExtra(KEY_DATE, date);
in.putExtra(KEY_DESC, description);
startActivity(in);
}
});
}
}
please, look closely at:
static final String KEY_DESC = "content:encoded";
I've tried with:
static final String KEY_DESC = "encoded";
and even with:
static final String KEY_DESC = "http://purl.org/rss/1.0/modules/content/encoded";
but nothing works.. doesn't show anything nor in Log.w when I set it nor on phone...
I'll even post parser class, I don't want any confusion:
public class XMLParser {
// constructor
public XMLParser() {
}

do you have count tag in your xml.have you checked?
because in numResults function.it returns result according to count tag in xml.

This code parses XML data from web service. It Works.
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_servis_uygulamasi);
Button btn=(Button)findViewById(R.id.button1);
btn.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
String pSoapAction = "http://tempuri.org/GetMagazaList";
String pMethodName = "GetMagazaList";
String pNameSpace = "http://tempuri.org/";
String pUrl ="";
SoapObject result =(SoapObject)getWebServisDATA(pUrl, pMethodName, pNameSpace, pSoapAction, "333");
TextView tv =(TextView)findViewById(R.id.textView2);
try

You should not be making URL connections in onCreate. This is discouraged in earlier Android versions and is enforced by the framework as of Honeycomb. You need to use a worker thread or (equivalently, but easier) an AsyncTask. See the Painless Threading blog post in the Android docs.

Use Dom xml parsing , see this sample here
and download this sample too
