所以我在尝试查找RegionCode /坐标状态时遇到了这个问题。我(假设)已经正确实现了来自Maps API的反向地理编码。但是,现在我只能对数据进行实际处理。我的代码是

 String API_KEY = "AIzaSyABXoV5ktBurLqodVntX6ImhNHOjDBgciQ";

 GeoApiContext apiContext = new GeoApiContext.Builder()
   .apiKey(API_KEY)
   .build();

 LatLng test = new LatLng( -8.96238,-40.68703);
 GeocodingApiRequest geocodingApi = GmapsController.reverseGeocode(apiContext, test);


所以现在我有了这个geocodingApiRequest我的问题是我将如何去接收RegionCode字符串甚至地址JSON

最佳答案

给定API规范,取决于您是否要同步,我希望以下两个可以工作:

GeocodingResult[] results = geocodingApi.await();
for (GeocodingResult result: results) {
  String address = result.formattedAddress;
  // use it or check other fields on `result`
}


或异步行为

class FutureCompletingCallback implements PendingResult.Callback<GeocodingResult[]> {
    final CompletableFuture<GeocodingResult[]> resultsFuture;

    FutureCompletingCallback(CompletableFuture<GeocodingResult[]> resultsFuture) {
         this.resultsFuture = resultsFuture;
    }

    public void onResult(GeocodingResult[] results) {
        resultsFuture.complete(results);
    }

    public void onFailure(Throwable t) {
        resultsFuture.compleExceptionally(t);
    }
}

CompletableFuture<GeocodingResult[]> resultsFuture = new CompletableFuture<>();
geocodingApi.setCallback(new FutureCompletingCallback(resultsFuture));
// collect result synchronously
GeocodingResult[] results = resultsFuture.get()
// OR act asynchronously
resultsFuture.whenComplete(...some action...);
