findViewById is not defined by Fragment

findViewById is not defined by Fragment

AutoCompleteTextView autoCompView =
(AutoCompleteTextView) findViewById(R.id.autocomplete_city);
Gives me an error
The method findViewById is undefined for the type CityFragment.
with:
public class CityFragment extends Fragment {
public CityFragment() {}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.city,
container, false);
AutoCompleteTextView autoCompView =
(AutoCompleteTextView) findViewById(R.id.autocomplete_city);
autoCompView.setAdapter(
new PlacesAutoCompleteAdapter(this,
R.layout.list_item)
);
return rootView;
}
}
I basically just copied the code from
https://developers.google.com/places/training/autocomplete-android
Any ideas why I get the error?
