获取附近地区的电话号码

标签: android google-maps google-places-api

我一直在关注显示附近地方的教程,在我的情况下,我需要附近的医院。我能够显示我当前的位置并显示附近的医院。但我想要做的是添加正在显示的医院的电话号码。我尝试在我的代码中添加formatted_phone_number,但它没有显示正确的电话号码,而是显示“-NA-”,这是没有可用号码时的默认值。

非常感谢任何帮助,谢谢!

GetNearbyPlacesData类的代码片段:

private void ShowNearbyPlaces(List<HashMap<String, String>> nearbyPlacesList) {
    for (int i = 0; i < nearbyPlacesList.size(); i++) {
        Log.d("onPostExecute","Entered into showing locations");
        MarkerOptions markerOptions = new MarkerOptions();
        HashMap<String, String> googlePlace = nearbyPlacesList.get(i);
        double lat = Double.parseDouble(googlePlace.get("lat"));
        double lng = Double.parseDouble(googlePlace.get("lng"));
        String placeName = googlePlace.get("place_name");
        String vicinity = googlePlace.get("vicinity");
        String formatted_phone_number = googlePlace.get("formatted_phone_number");
        LatLng latLng = new LatLng(lat, lng);
        markerOptions.position(latLng);
        markerOptions.title(placeName + " : " + vicinity);
        markerOptions.snippet(vicinity + formatted_phone_number);
        mMap.addMarker(markerOptions);
        markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED));
        //move map camera

1 个答案:

答案 0 :(得分:1)

在MapsActivity.class中,函数getUrl()正在&#34;医院&#34;作为supported types列表中不存在的参数之一。因此,结果类型是默认值,因为它不匹配任何支持的类型。 该回复将为您提供搜索请求附近所有地点的类型&#39;默认&#39;。要向Nearby Places API请求附近的医院,请通过医院而不是医院。

在代码中,您向Nearby Places API发出请求,并且不会返回formatted_phone_number作为响应。有关更多信息,请参阅documentation

要获取电话号码(formatted_phone_number或international_phone_number),请使用PlaceId向Place Details API发出请求。
