I'm having some issue creating a layout for a league table. In my current layout, i have created a table with consists of two rows. The first row has the headings i want, and the second row has black fields that consist of the data that is obtained. I get the data from my server which contains an xml file. The problem i am having is not getting the data as i can do that.. The problem is that when i display the data i use a ListAdapter which need a layout linked to it. But when i link the appropriate layout, i get a repeat of header after every line... e.g.
TEAM P W L D P
Arsenal 1 1 1 1 1
TEAM P W L D P
Aston Villa 1 1 1 1 1
I'm sure its a simple error to fix.... maybe i have to you something else to display the data???
Below is the code for the main
public class tab_1 extends ListActivity {
public int a = Football_appActivity.league;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listplaceholder);
ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
if(a==1){
String xml = XMLfunctions.getXML_prem_table();
Document doc = XMLfunctions.XMLfromString(xml);
int numResults = XMLfunctions.numResults(doc);
if((numResults <= 0)){
Toast.makeText(tab_1.this, "League Table", Toast.LENGTH_LONG).show();
finish();
}
NodeList nodes = doc.getElementsByTagName("team");
for (int i = 0; i < nodes.getLength(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element)nodes.item(i);
map.put("id", XMLfunctions.getValue(e, "id"));
map.put("name", "" + XMLfunctions.getValue(e, "name"));
map.put("played", "" + XMLfunctions.getValue(e, "played"));
map.put("won", "" + XMLfunctions.getValue(e, "won"));
map.put("drawn", "" + XMLfunctions.getValue(e, "drawn"));
map.put("lost", "" + XMLfunctions.getValue(e, "lost"));
map.put("points", "" + XMLfunctions.getValue(e, "points"));
mylist.add(map);
}
**
ListAdapter adapter = new SimpleAdapter(this, mylist , R.layout.main_tab,
new String[] { "name", "played", "won", "drawn", "lost", "points"},
new int[] { R.id.item_title, R.id.item_played, R.id.item_won,
R.id.item_drawn, R.id.item_lost, R.id.item_points});**
setListAdapter(adapter);
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
@SuppressWarnings("unchecked")
HashMap<String, String> o = (HashMap<String, String>) lv.getItemAtPosition(position);
Toast.makeText(tab_1.this, o.get("name") + " have Won '" + o.get("won") + "' games, and are currently on '" + o.get("points") + "' points!", Toast.LENGTH_LONG).show();
}
});
}
Below is the layout called main_tab.xml
<?xml version="1.0" encoding="utf-8"?>

Ok cool.. so i have changed the layout of the main_tab.xml and created a new layout called table_header.xml That contains the headings for the league e.g. Name, Played, Won, Lost etc... But now i have an error in the logcat.. Below is the code what for main page...
if(a==1){
String xml = XMLfunctions.getXML_prem_table();
Document doc = XMLfunctions.XMLfromString(xml);
int numResults = XMLfunctions.numResults(doc);
if((numResults <= 0)){
Toast.makeText(tab_1.this, "League Table", Toast.LENGTH_LONG).show();
finish();
}
NodeList nodes = doc.getElementsByTagName("team");
setContentView(R.layout.table_header);
for (int i = 0; i < nodes.getLength(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element)nodes.item(i);
map.put("id", XMLfunctions.getValue(e, "id"));
map.put("name", "" + XMLfunctions.getValue(e, "name"));
map.put("played", "" + XMLfunctions.getValue(e, "played"));
map.put("won", "" + XMLfunctions.getValue(e, "won"));
map.put("drawn", "" + XMLfunctions.getValue(e, "drawn"));
map.put("lost", "" + XMLfunctions.getValue(e, "lost"));
map.put("points", "" + XMLfunctions.getValue(e, "points"));
mylist.add(map);
}
ListAdapter adapter = new SimpleAdapter(this, mylist , R.layout.main_tab,
new String[] { "name", "played", "won", "drawn", "lost", "points"},
new int[] { R.id.item_title, R.id.item_played, R.id.item_won,
R.id.item_drawn, R.id.item_lost, R.id.item_points});
setListAdapter(adapter);
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
@SuppressWarnings("unchecked")
HashMap<String, String> o = (HashMap<String, String>) lv.getItemAtPosition(position);
Toast.makeText(tab_1.this, o.get("name") + " have Won '" + o.get("won") + "' games, and are currently on '" + o.get("points") + "' points!", Toast.LENGTH_LONG).show();
}
});
The line for changing the layout i have used is: setContentView(R.layout.table_header);
is this correct????
The first error i get is (there is a long list, but i think this is the cause):
04-15 09:46:42.268: E/AndroidRuntime(346): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.julian.football_app/com.julian.football_app.tab_1}: java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'
