[android-developers] Error

[aashutosh]

I have a button in main activity which activates another activity
whose code is as follows:


--
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listplaceholder);

ArrayListHashMapString, String mylist = new
ArrayListHashMapString, String();


String xml = XMLfunctions.getXML();
Document doc = XMLfunctions.XMLfromString(xml);

int numResults = XMLfunctions.numResults(doc);

if((numResults = 0)){
finish();
}

NodeList nodes = doc.getElementsByTagName(tournaments);

for (int i = 0; i  nodes.getLength(); i++) {
HashMapString, String map = new HashMapString, 
String();

Element e = (Element)nodes.item(i);
map.put(id, XMLfunctions.getValue(e, id));
map.put(name,  + XMLfunctions.getValue(e, name));
map.put(date, Date Started:  + XMLfunctions.getValue(e,
date));
map.put(nextmatch, Next Match:  +
XMLfunctions.getValue(e, nextmatch));
mylist.add(map);
}

ListAdapter adapter = new SimpleAdapter(this, mylist ,
R.layout.main1,
new String[] { name, date,nextmatch },
new int[] { R.id.item_title,
R.id.item_subtitle,R.id.item_subsubtitle });

setListAdapter(adapter);

final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView? parent, View view, int
position, long id) {

if(position==0)
{
Intent intent=new
Intent(Ongoingtournaments.this,info1.class);
startActivity(intent);
}
}
the XMLfunctions class do the work of XML parsing.
