android - 与邮政编码的位置距离

Question

Android API 有Location.distanceBetween()，它接受两个纬度/经度值并返回以米为单位的距离。有没有一种方法可以让我只有一个邮政编码才能达到这个距离？

You may want to use Android's Geocoder API. Something like this should work:

String locationName = zipCode + ", " + countryName;
Geocoder geoCoder = new Geocoder(context, Locale.getDefault());     
try {
    List<Address> address = geoCoder.getFromLocationName(locationName, 1);    
    double latitude = address.get(0).getLatitude();
    double longitude = address.get(0).getLongitude();
    Location.distanceBetween(...);
} catch (IOException e) {
    e.printStackTrace();
}

You need to include the country's name because of this: Get latitude and longitude based on zip using Geocoder class in Android
