Not getting output while parsing the xml - android

I am using soap webservice and I have got the proper response, now i want to parse the response I have written code for that but I am not getting output, Can someone help me ?

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.

you should parse your XML with the help of xml pull parser
Following code will guide you for doing so
MyXmlPullParser objMyXmlPullParser = new MyXmlPullParser(context);
List<Map<String , String>> list = objMyXmlPullParser.readXml("Xml respose put here", "Table");
public class MyXmlPullParser
{
Context _context ;
public MyXmlPullParser(Context _context)
{
this._context = _context ;
}
public List<Map<String , String>> readXml(String XmlString , String ParentTag)
{
Map<String , String > map = new HashMap<String, String>();
List<Map<String , String >> list = new ArrayList<Map<String , String >>();
try
{
String Tag = "" ;
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser xpp = factory.newPullParser();
xpp.setInput(new StringReader (XmlString));
int eventType = xpp.getEventType();
while (true)
{
if(eventType == XmlPullParser.START_TAG)
{
Tag = xpp.getName();
}
else if(eventType == XmlPullParser.END_TAG)
{
Tag = "" ;
if(xpp.getName().equals(ParentTag))
{
list.add(map);
map = new HashMap<String, String>();
}
}
else if(eventType == XmlPullParser.TEXT)
{
String text = xpp.getText();
if(!Tag.equals("") && !Tag.equals(ParentTag))
{
map.put(Tag, text);
}
}
else if(eventType == XmlPullParser.END_DOCUMENT)
{
System.out.println("End document");
break ;
}
eventType = xpp.next();
}
}
catch (XmlPullParserException e)
{
Log.e("xml reader" , "error in parsing xml");
return null ;
}
catch (IOException e)
{
Log.e("xml reader" , "error in IO in xml");
return null ;
}
return list ;
}
Hope it may helps you

The application has stopped unexpectedly, specific case on android

Ok, I am working on one android application. It has many features, such as showing the News, Horoscope, TV schedule, Weather forecast ... Every piece of information is comming to me through RSS, using XML. Application works as it is supposed to do when I have wifi or 3G, but as soon as there is no wifi or 3G signal, or some of the links are down under maintenance I get kicked out of application and error like:
The application has stopped unexpectedly! Please Try Again.
I was trying to make some Activity that will show something like:
There was a problem with your request! Please make sure that wifi or 3G signals are available or try again later.
I've tried many ways but nothing seams to work. Here are a few classes that might help:

}
So basically, what I want to do is not to check whether there is or not wifi or 3G. I just want to implement that Activity that will show that there is an error and not allow instantly kicking out of application whenever error occures. Please, anyone?
To check if the device is connected to Wifi or 3G, you could create a method like this:
public boolean isOnline() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if(netInfo != null && netInfo.isConnected()) {
return true;
}
return false;
}
Then, if the Activity you are trying to launch is dependent on internet connection, you could do:
if(!isOnline) {
Toast.makeText(getApplicationContext(), "You are not connected to the internet", Toast.LENGTH_SHORT).show();
} else {
startActivity(*yourIntent);
}
You'll need these permissions in your manifest:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

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.

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

how to parse the xsd schema in android

I am using soap webService and using that I have received the response which is in xsd schema format. I dont know how to parse it, I have tried the code but its not working,Can someone help me.
My Main Class is
public class Mylearning extends ListActivity {
//ArrayList<cat> list = null;
private static final String SOAP_ACTION="http://yyy.mobi/GetLearningPortalsList";
private static final String METHOD_NAME ="GetLearningPortalsList";
private static final String NAMESPACE ="http://yyy.mobi/";
private static final String URL = "http://webservices.yyy.mobi/MobileLMSServices.asmx";
private Bundle bundleResult = new Bundle();
private JSONObject JSONObj;
private JSONArray JSONArr;
//private ArrayList<HashMap<String, Object>> myList;
SoapObject request;
TextView tv;
TextView tv1;
TextView tv2;
ListView mainListView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylearning);
//mainListView = (ListView) findViewById(R.id.main_listview);
request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("SiteURL","http://www.yyy.mobi/");
request.addProperty("PageID","1");
request.addProperty("SearchText","");
ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
SoapObject result = null;
envelope.setOutputSoapObject(request);
AndroidHttpTransport sab = new AndroidHttpTransport(URL);
sab.debug = true;
try {
sab.call(SOAP_ACTION, envelope);
if (envelope.getResponse() != null) {
result = (SoapObject) envelope.bodyIn;
String[] values = new String[result.getPropertyCount()];
int j = result.getPropertyCount();
String repons=result.toString();
// Log.d("result",repons.toString());
Document doc = XMLfunctions.XMLfromString(repons);
int numResults = XMLfunctions.numResults(doc);
if((numResults <= 0)){
Toast.makeText(Mylearning.this, "Geen resultaten gevonden", Toast.LENGTH_LONG).show();
finish();
}
NodeList nodes = doc.getElementsByTagName("result");
for (int i = 0; i < nodes.getLength(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element)nodes.item(i);
map.put("Course", XMLfunctions.getValue(e, "Course"));

}
});
}
}
catch (Exception e) {
e.printStackTrace();
}
}
}
My Xmlfunction class is
public class XMLfunctions {
public final static Document XMLfromString(String repons){
Document doc = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();

doc = db.parse(is);
Log.d("doc", doc.toString());
} catch (ParserConfigurationException e) {
System.out.println("XML parse error: " + e.getMessage());
return null;
} catch (SAXException e) {
System.out.println("Wrong XML file structure: " + e.getMessage());
return null;
} catch (IOException e) {
System.out.println("I/O exeption: " + e.getMessage());
return null;
}
return doc;
}
public final static String getElementValue( Node elem ) {
Node kid;
if( elem != null){
if (elem.hasChildNodes()){
for( kid = elem.getFirstChild(); kid != null; kid = kid.getNextSibling() ){
if( kid.getNodeType() == Node.TEXT_NODE ){
return kid.getNodeValue();
}
}
}
}
return "";
}
public static int numResults(Document doc){
Node results = doc.getDocumentElement();
int res = -1;
try{
res = Integer.valueOf(results.getAttributes().getNamedItem("count").getNodeValue());
}catch(Exception e ){
res = -1;
}
return res;
}
public static String getValue(Element item, String str) {
NodeList n = item.getElementsByTagName(str);
return XMLfunctions.getElementValue(n.item(0));
}
}
Take a look at this discussion
You can use the ksoap2 a SOAP Client Library to parse Responses
