PlaceAutocomplete不适用于setBoundsBias

Question

我使用带有setBoundsBias的PlaceAutocomplete来更精确地限制城市地址，但是当我输入Autocomplete时，不能使用我设置的边界。

请帮助我，谢谢！

LatLngBounds latLngBounds = new LatLngBounds(new LatLng(15.924677, 108.335373), new LatLng(16.218292, 107.821762));
AutocompleteFilter filter = new AutocompleteFilter.Builder()
                .setCountry("VN")
                .setTypeFilter(AutocompleteFilter.TYPE_FILTER_ADDRESS)
                .build();
try {
        Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY)
                    .setBoundsBias(latLngBounds)
                    .setFilter(filter)
                    .build(this);
            startActivityForResult(intent, REQUEST_CODE_AUTOCOMPLETE);
        } catch () {
        }
