when i call the notifyDataSetChanged(), but the getView seems not work
as expect.
for example, there are 10 rows, after my filter by Filterable
interface, there's 1 row left, and i call notifyDataSetChanged()
, so the getView would excute 10 times, but not 1 time
how to rebind the list data after filter?
this is my code:
static class ContactListAdapter extends BaseAdapter implements
Filterable {
private final NameFilter filter;
@Override
public Filter getFilter() {
// TODO Auto-generated method stub
return filter;
}
private class NameFilter extends Filter{
@Override
protected FilterResults performFiltering(CharSequence
constraint) {
final FilterResults oReturn = new
FilterResults();
final ArrayList<Contact> results = new
ArrayList<Contact>();
//if (arrayContacts == null)
arrayContacts = mListContacts.getContacts();
if (constraint != null)
if (arrayContacts != null &&
arrayContacts.size() > 0) {
for (final Contact c :
arrayContacts) {
if
(c.getDisplayName().startsWith(
constraint.toString()))
results.add(c);
}
}
oReturn.values = results;
return oReturn;
}
@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
arrayContacts = (ArrayList<Contact>)
results.values;
Log.i("info", "filtered contacts count:" +
Integer.toString(arrayContacts.size()));
notifyDataSetChanged();
}
}
}
