获取两个地理点之间的距离

Get the distance between two geo points(获取两个地理点之间的距离)

问题描述

我想制作一个应用程序来检查用户最近的位置.我可以轻松获取用户的位置，并且我已经有了一个经纬度的地点列表.

I want to make an app which checks the nearest place where a user is. I can easily get the location of the user and I have already a list of places with latitude and longitude.

根据当前用户位置了解列表中最近位置的最佳方法是什么.

What would be the best way to know the nearest place of the list against the current user location.

我在谷歌 API 中找不到任何东西.

I could not find anything in the google APIs.

推荐答案

Location loc1 = new Location("");
loc1.setLatitude(lat1);
loc1.setLongitude(lon1);

Location loc2 = new Location("");
loc2.setLatitude(lat2);
loc2.setLongitude(lon2);

float distanceInMeters = loc1.distanceTo(loc2);
