Aby skonfigurować styl oparty na danych w przypadku zbiorów danych, wykonaj te czynności.
Uzyskiwanie klucza interfejsu API i włączanie interfejsów API
Zanim zaczniesz używać stylów opartych na danych w przypadku zbiorów danych, musisz mieć: projekt w Google Cloud z kontem rozliczeniowym oraz włączone pakiety Maps SDK na Androida i Maps Datasets API. Więcej informacji znajdziesz w tych artykułach:
Ulepszony mechanizm renderowania map jest dostępny od wersji 18.0.0 pakietu Maps SDK na Androida. Ten moduł renderujący wprowadza wiele ulepszeń, w tym obsługę definiowania stylów map w Google Cloud, w pakiecie Maps SDK na Androida.
Wraz z wprowadzeniem pakietu SDK Map Google na Androida w wersji 18.2.0 Google zmieniło domyślny mechanizm renderowania z starszego na ulepszony. Ta zmiana oznacza, że ulepszony moduł renderowania mapy jest teraz domyślnie używany w aplikacji podczas tworzenia nowej aplikacji lub przebudowywania istniejącej.
Tworzenie identyfikatora mapy
Aby utworzyć nowy identyfikator mapy, wykonaj czynności opisane w sekcji Tworzenie identyfikatora mapy. Ustaw typ mapy na Android.
Styl oparty na danych w przypadku zbiorów danych wymaga identyfikatora mapy. Jeśli identyfikator mapy jest nieprawidłowy lub go brakuje, styl oparty na danych w przypadku zbiorów danych nie może się wczytać. W ramach rozwiązywania problemów możesz użyć MapCapabilities, aby sprawdzić, czy styl oparty na danych w przypadku zbiorów danych jest obsługiwany.

To learn more, see:\n\n- [Set up your Google Cloud project](/maps/documentation/android-sdk/cloud-setup)\n\n- [Enable Maps SDK for Android and get an API key](/maps/documentation/android-sdk/get-api-key)\n\n- [Enable the Maps Datasets API](https://console.cloud.google.com/apis/library/mapsplatformdatasets.googleapis.com)\n\nEnable the new maps renderer\n\nAn upgraded map renderer is available as of version 18.0.0 of the\nMaps SDK for Android. This renderer brings many improvements, including\nsupport for Cloud-based maps styling, to Maps SDK for Android.\n\nWith the release of version 18.2.0 of the Maps SDK for Android, Google switched the\ndefault renderer from the legacy renderer to the upgraded map renderer. This\nchange means that the upgraded map renderer is now used by default in your app\nwhen you build a new app or rebuild an existing app.\n| **Caution:** To use data-driven styling for datasets in your app, your app must be built using the upgraded map renderer. If you are adding data-driven styling for datasets to an existing app, rebuild the app to use the upgraded map renderer. For more information, see [New Map Renderer](/maps/documentation/android-sdk/renderer).\n\nCreate a map ID\n\nTo create a new map ID, follow the steps at\n[Create a map ID](/maps/documentation/get-map-id#create-a-map-id). Be sure to\nset the Map type to **Android**.\n\nCreate a new map style\n\nTo create a new map style, follow the instructions in\n[Create and use map styles](/maps/documentation/android-sdk/cloud-customization/map-styles)\nto create the style, and\n[associate the style with the map ID you just created](/maps/documentation/android-sdk/cloud-customization/map-styles#associate-style-with-map-id).\n\nUpdate your map initialization code\n\nThis step requires the map ID you just created. It can be found on your\n[Maps Management](https://console.cloud.google.com/google/maps-apis/studio/maps) page.\n\nTo add the map ID to your initialization code, see\n[Add the map ID to your app](/maps/documentation/get-map-id#add-a-map-id-to-your-app).\n\nCheck map capabilities (required)\n\nData-driven styling for datasets requires a map ID. If the map ID is missing, or an\ninvalid map ID is passed, data-driven styling for datasets cannot load. As a\ntroubleshooting step, you can use\n[`MapCapabilities`](/android/reference/com/google/android/gms/maps/model/MapCapabilities)\nto check if data-driven styling for datasets is supported.\n| **Caution:** Some devices might not support the new map renderer and therefore cannot display data-driven styling for datasets. You must use `MapCapabilities` to check for support at runtime. If data-driven styling for datasets is not supported, define a fallback option. For device requirements for the new map renderer, see [Supported\ndevices](/maps/documentation/android-sdk/renderer#supported-devices). \n\nKotlin\n\n\n```java\nval capabilities: MapCapabilities = googleMap.getMapCapabilities()\nSystem.out.println(\"Data-driven Styling is available: \" + capabilities.isDataDrivenStylingAvailable())\n```\n\n\u003cbr /\u003e\n\nJava\n\n\n```java\nMapCapabilities capabilities = googleMap.getMapCapabilities();\nSystem.out.println(\"Data-driven Styling is available: \" + capabilities.isDataDrivenStylingAvailable());\n```\n\n\u003cbr /\u003e\n\nNext steps\n\n- [Create and manage a dataset](/maps/documentation/android-sdk/dds-datasets/create-dataset)"]]
