Question

将半径比转换为km或米。

如果我把radius = 500怎么办？半径500到公里或米的等效性是多少？

1个半径到公里是多少？

   StringBuilder googlePlacesUrl = new StringBuilder("https://maps.googleapis.com/maps/api/place/nearbysearch/json?");
        googlePlacesUrl.append("location=" + latitude + "," + longitude);
        googlePlacesUrl.append("&radius=10000");
        googlePlacesUrl.append("&type=" + "art_gallery");
        googlePlacesUrl.append("&sensor=true");
        googlePlacesUrl.append("&key=" + "AIzaSyCx8-ZK6m5FTgEoTaSRaUuALV-5Vnz1Co4");
        Log.d("getUrl", googlePlacesUrl.toString());
        return (googlePlacesUrl.toString());

半径参数以米为单位。所以你应该用米转换，然后在下面的url中传递它。

StringBuilder googlePlacesUrl = new StringBuilder("https://maps.googleapis.com/maps/api/place/nearbysearch/json?");
    googlePlacesUrl.append("location=" + latitude + "," + longitude);
    googlePlacesUrl.append("&radius=10000");
    googlePlacesUrl.append("&type=" + "art_gallery");
    googlePlacesUrl.append("&sensor=true");
    googlePlacesUrl.append("&key=" + "AIzaSyCx8-ZK6m5FTgEoTaSRaUuALV-5Vnz1Co4");
    Log.d("getUrl", googlePlacesUrl.toString());
    return (googlePlacesUrl.toString());
