Hello Guys,
I've written the following but I cannot figure out how to add the non
scrolling header Item. If I only extent an Activity then I cannot
override the onListItemClick method. This is why I have written it to
use the ListActivity class. Any help would be greatly appreciated,
here is my code so far:
public class HelloListAdapter extends ListActivity {
private ListView lv;
private TextView tv;
private ListAdapter la;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tv = new TextView(this);
tv.setText("Hello Text, Top of List");
lv = (ListView) getListView();
lv.addHeaderView(tv);
la = (ListAdapter) new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, COUNTRIES);
lv.setAdapter(la);
}
static final String[] COUNTRIES = new String[] {
"Afghanistan", "Albania", "Algeria", "American Samoa",
"Andorra",
"Angola", "Anguilla", "Antarctica", "Antigua and Barbuda",
"Argentina"
};
}
