I currently have a listview which contains a couple of strings. These are called from a string array in strings.xml
<string name="app_name">Taxi Me</string>
<string-array name="taxi_array">
<item>Barrys Taxi</item>
<item>Boom Taxi</item>
</string-array>
What I was trying to do is create subitems for these so that i can show fields such as address and contact details etc. I made a customlistview a while back but cant work out how I can do it using the strings.xml file? Are there any particular tags I need to use so they show up in the list view?
Main Activity Code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final String[] taxi = getResources().getStringArray(R.array.taxi_array);
final String[] address = getResources().getStringArray(R.array.taxi_add);
setListAdapter(new ArrayAdapter<String>(this, R.layout.listtaxi, taxi));
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
for (int i = 0; i < taxi.length; i++) {
lv.add(new ListTaxi (taxi[i], address[i]));
}
/*lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
Toast.LENGTH_LONG).show();
}
});
*/
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> a, View v, final int position, long id)
{
final int selectedPosition = position;
AlertDialog.Builder adb=new AlertDialog.Builder(ListTaxi.this);
adb.setTitle("Taxi Booking");
adb.setMessage("You Have Selected: "+lv.getItemAtPosition(position));
adb.setPositiveButton("Book", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(getApplicationContext(), Booking.class);
intent.putExtra("booking", taxi[selectedPosition]);
startActivity(intent);
}
});
adb.setNegativeButton("Cancel", null);
adb.show();
}
});
EDIT: Okay, just for kicks, I threw this together. It compiles and functions correctly, see if you can adapt it for your particular needs:

_____END EDIT_______
You'd probably be better off using a database for something like this, to keep the records tied together. If you're set on using arrays, one thing you could do is make a separate array for each item you need (e.g. taxi_array, taxi_address_array, taxi_phone_array) then make a Taxi object in your code:
class Taxi {
String taxiName;
String taxiAddress;
String taxiPhone;
public Taxi(String name, String address, String phone) {
taxiName = name;
taxiAddress = address;
taxiPhone = phone;
}
}
private List<Taxi> taxiList;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String[] taxiNames = getResources().getStringArray("taxi_array");
String[] taxiAddresses = getResources().getStringArray("taxi_address_array");
String[] taxiPhones = getResources().getStringArray("taxi_phone_array");
taxiList = new ArrayList<Taxi>();
for (int i = 0; i < taxiNames.length; i++) {
taxiList.add(new Taxi(taxiNames[i], taxiAddresses[i], taxiPhones[i]));
}
}
(This is uncompiled code, some tweaks may be needed) But then you'll have a List of Taxi items, containing all of the compiled information from the different arrays. A database would still be a much better option (or even a CSV file with the data, in your assets).
