Hello!
I extend AutoCompleteTextView and override preformFiltering function in order to get results from database. I'm getting the results but then nothing is shown. And getView in custom adapter is never called. The strange thing that If I preload items (inside init() function) I can see them... May by anyone can point me to the right solution? Thanks.
public class CityAutoCompleteTextView extends AutoCompleteTextView {
private DataDatabase mCity;
private CityAutoCompleteArrayAdapter mCityAutoCompleteAdapter;
private ArrayList<CityAutoCompleteListItem> mCityListItems;
public CityAutoCompleteTextView(Context context) {
super(context);
init();
}
public CityAutoCompleteTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public CityAutoCompleteTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public City getItem(int position) {
return mCityAutoCompleteAdapter.getItem(position).getCity();
}
private void init() {
mCity = new DataDatabase(this.getContext());
mCityListItems = new ArrayList<CityAutoCompleteListItem>();
mCityAutoCompleteAdapter = new CityAutoCompleteArrayAdapter(this.getContext(), R.layout.autocomplete_list, mCityListItems);
this.setAdapter(mCityAutoCompleteAdapter);
}
@Override
protected void performFiltering(CharSequence text, int keyCode) {
String stext = text.toString();
Cursor cur = mCity.getCitiesMatches(stext);
mCityListItems.clear();
if (cur==null) {
mCityAutoCompleteAdapter.notifyDataSetChanged();
return;
}
while(!cur.isAfterLast()) {
City city = new City(cur.getInt(0),cur.getString(1));
CityAutoCompleteListItem item = new CityAutoCompleteListItem(city, "Unknown province/state",cur.getString(2));
mCityListItems.add(item);
cur.moveToNext();
};
cur.close();
mCityAutoCompleteAdapter.notifyDataSetChanged();
super.performFiltering(text, keyCode);
}
}
