两个已知的 android 地理位置之间的角度 [英] Angle between two known android geolocations

问题描述

我想找到两个已知地理位置之间的角度.基本上我想要的是，我想引导一个箭头，它的尾点在我当前的位置，箭头指向一个固定的地理位置.所以我在想，如果不知何故，我能够在这两个地理位置之间获得一个角度，那么我也可以这样做.

I want to find an angle between two known geolocations.Basically what I want is, I want to direct an arrow whose tail point is at my current location and arrow head is pointing towards a fixed geolocation. So I am thinking if somehow, I am able to get an angle between these two geolocations then propably i will be able to do the same.

你们有什么建议可以更好地做到这一点.任何帮助将不胜感激.

Do you guys have some suggestions to do it in a better manner. Any help would be appreciated.
