创建使用半正矢公式，Android的V2的方法 [英] Creating a method using Haversine Formula, Android V2

问题描述

我不是真的很好用的数学，但我需要计算的标记两个不同位置的距离。事情是这样的：

I'm not really good with mathematics but I need to calculate the distance of two different locations of the markers. Something like this:

public double CalculationByDistance(double initialLat, double initialLong, double finalLat, double finalLong){

return distance;
}

或者是有，我可以计算出两个标记的距离的任何其他方法，我也尝试过谷歌的答案..但找不到任何。

Or is there any alternative ways that I can calculate the distance of two markers, also I tried to google for answers.. but couldn't find any.

参考： http://en.wikipedia.org/wiki/Haversine_formula

注释是AP preciated :)谢谢！

Comments are appreciated :) Thanks!!

推荐答案

试试这个，比半正矢简单多了！

Try this, much simpler than Haversine!

Location me   = new Location("");
Location dest = new Location("");

me.setLatitude(myLat);
me.setLongitude(myLong);

dest.setLatitude(destLat);
dest.setLongitude(destLong);

float dist = me.distanceTo(dest);
