Как ограничить автозаполнение google местами в конкретной стране?

Я хочу ограничить свои места для захвата auto complete api в конкретной стране только сейчас, когда я получаю все предложения по всему миру … Пожалуйста, решите проблему заранее

В Android мы можем ограничиться таким образом:

Добавить AutoCompletionFilter в коде вместо того, чтобы передавать значение null


Чтобы ограничить автозагрузку Google в Австралии.

 AutocompleteFilter filter = new AutocompleteFilter.Builder().setCountry("AU").build(); 

Страна ограничивает результаты. Это должен быть код страны ISO 3166-1 Alpha-2 (без учета регистра). Если это не будет установлено, фильтрация не будет происходить. См. Эту ссылку для разных кодов стран https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2

@Saipraneeth Nandi Исправьте строку вашего кода, как показано ниже:

 mPlaceArrayAdapter = new PlaceArrayAdapter(this, android.R.layout.simple_list_item_1, LAT_LNG_BOUNDS, filter); 

Просто добавьте это в свой запрос, который вы отправляете в google places api:

 components=country:your_country_code 

Здесь вы можете найти код страны.

Пример :

 https://maps.googleapis.com/maps/api/place/autocomplete/json?input=bhubaneshwar&components=country:in&sensor=false&key=your_key 

Дайте мне знать, если это то, что вы хотите.
