Solicita el generador de vistas de la IU de sugerencias de búsqueda

Para obtener la vista de la IU de las sugerencias de búsqueda, primero debes obtener su generador siguiendo estos pasos:

Permite que tu clase Activity de destino implemente la interfaz GetSearchSuggestionsViewGeneratorCallback o usa la clase interna anónima.
Anula los métodos onSuccess(SearchSuggestionsViewGenerator) y onError(String) de la interfaz GetSearchSuggestionsViewGeneratorCallback.
Construye la instancia de la clase GetSearchSuggestionsViewOptions con una lista de contextos de búsqueda. (Opcional) Este objeto también toma un objeto SearchSuggestionsViewOptions que proporciona algunas opciones para personalizar el aspecto de la IU de las sugerencias de búsqueda.
Llama a la función getSearchSuggestionsView(GetSearchSuggestionsViewOptions, GetSearchSuggestionsViewGeneratorCallback) de SearchInAppsService.
Después de obtener el generador de IU, puedes considerar almacenarlo en un ViewModel para que no tengas que solicitar el generador de nuevo cuando la actividad deba volver a crearse (por ejemplo, cuando cambia la configuración mientras se ejecuta la app).

Cómo solicitar sugerencias de búsqueda basadas en la ubicación

El punto de entrada getSearchSuggestionsView también admite sugerencias de búsqueda basadas en la ubicación. Sigue estos pasos para compilar un objeto GetSearchSuggestionsViewOptions con una lista de objetos LocationContext. Luego, pasa el GetSearchSuggestionsViewOptions a la función getSearchSuggestionsView, siguiendo los pasos de la sección anterior.

(Obligatorio) Compila el objeto LocationContext con el objeto GeographicalRestrictions. El objeto GeographicalRestrictions toma un objeto CircularArea que contiene la latitud y longitud del centro del área y el radio del área.
(Opcional) Compila el objeto TimeRestrictions con el objeto TimeSegment. El objeto TimeSegment toma una cadena que representa el segmento de tiempo en formato ISO 8601.
Compila el objeto GeoTypeRestrictions con los tipos geográficos solicitados (opcional). Los tipos proporcionados se usan para ajustar la clasificación y el filtrado de los resultados que muestra el servicio. Los valores admitidos son: "restaurant", "cafe", "bar", "park", "zoo", "museum", "attraction", "atm", "bank", "hair_salon", "real_estate_agency", "bicycle_sharing_location", "car_rental_agency", "shopping_center", "grocery_store" y "hotel".

Cómo agregar la vista de la IU de sugerencias de búsqueda

Para getSearchSuggestionsView, el resultado final es un objeto SearchSuggestionsViewGenerator. Puedes usar la función populateView(Context) de este objeto para generar la vista de la IU y updateView(View) para actualizar la vista existente (especialmente para apps de Jetpack Compose).

En el caso de las apps de Jetpack Compose, debes usar AndroidView para consumir la vista clásica generada.
