Google警告我們有關 PlaceID 的更改并提出建議；由于 Google 地圖數據庫的大規模更新，地點 ID 可能會發生變化。在這種情況下，地點可能會收到新的地點 ID，而舊 ID 會返回 NOT_FOUND 響應。您可以免費刷新地點 ID，方法是發出地點詳細信息請求，僅在字段參數中指定 ID 字段。不幸的是，他們的網站上沒有 Java/Kotlin 的示例代碼，除了指向他們的Web 服務的鏈接String placeID ="Some place ID"; List<Place.Field> placeFields = Arrays.asList( Place.Field.ID, ); // Construct a request object, passing the place ID and fields array. FetchPlaceRequest request = FetchPlaceRequest.builder(placeID, placeFields).build(); placesClient.fetchPlace(request).addOnSuccessListener((response) -> { Place place = response.getPlace(); if (!placeID.equals(place.getId())) { //update your old placeID } }).addOnFailureListener((exception) -> { if (exception instanceof ApiException) { //Place removed. } });這是用 Java 更新 placeID 的正確方法嗎？

我測試了我的數據庫并發現了發生更新的情況。下面的代碼包含更新的 placeID、刪除的 placeID 和仍然有效的 palceID，以便進行測試。
ArrayList<String> placeIDsList = new ArrayList<>();
placeIDsList.add("ChIJTaKjynxesBQREvi1CU5QUFg");
placeIDsList.add("EjhDdW1odXJpeWV0IE1haGFsbGVzaSwgVXp1biBTay4sIEV6aW5lL8OHYW5ha2thbGUsIFR1cmtleSIuKiwKFAoSCakQkmN8XrAUEVkLpNK_F4IJEhQKEgmFzKyYe16wFBGSjU7F2ooIIg");
placeIDsList.add("hIJy9YVxdxpsBQRq0-xUVJdZQ8");
// Specify the fields to return (in this example all fields are returned).
List<Place.Field> placeFields = Arrays.asList(Place.Field.ID);
for (String plc : placeIDsList ) {
// Construct a request object, passing the place ID and fields array.
FetchPlaceRequest request = FetchPlaceRequest.builder(plc, placeFields).build();
Log.e(TAG,"request for place with ID = " + plc);
placesClient.fetchPlace(request).addOnSuccessListener((response) -> {
Place place = response.getPlace();
if (!plc.equals(place.getId())) {
Log.e(TAG,"placeID renewed");
Log.e(TAG,"placeID old = " + plc);
Log.e(TAG,"placeID new = " + place.getId());
} else {
Log.e(TAG, "Place found: " + place.getId());
}
}).addOnFailureListener((exception) -> {
if (exception instanceof ApiException) {
ApiException apiException = (ApiException) exception;
int statusCode = apiException.getStatusCode();
// Handle error with given status code.
Log.e(TAG, "Place with ID "+plc+" not found");
Log.e(TAG, "Exception message is :" + exception.getMessage());
Log.e(TAG, "Status code = " + statusCode);
}
});
}
輸出是
E/MapsActivity: request for place with ID = ChIJTaKjynxesBQREvi1CU5QUFg

E/MapsActivity: Place with ID hIJy9YVxdxpsBQRq0-xUVJdZQ8 not found
E/MapsActivity: Exception message is :9012: INVALID_REQUEST
E/MapsActivity: Status code = 9012
E/MapsActivity: Place found: ChIJTaKjynxesBQREvi1CU5QUFg
似乎是status code 9102找不到地方。
