尋找我和朋友之間最近的距離 (Finding nearest distance between me and friends)

問題描述

尋找我和朋友之間最近的距離 (Finding nearest distance between me and friends)

我需要在 android.now 我有我的當前位置，我的意思是緯度、經度和朋友位置集找到最近的位置。我需要找到離我最近的朋友？誰能建議我如何在android中做到這一點？

參考解法

方法 1:

Use Location class. It has a method called distanceTo(Location loc) to calculate the distance between two Locations.

Location myLocation = new Location("LocProvider");
myLocation.setLatitude(latitude);
myLocation.setLongitude(longitude);

//Same as above, Setup friendLocation 

float distance = myLocation.distanceTo(friendLocation);
