两个已知的Andr​​oid geolocations之间的角度 [英] Angle between two known android geolocations

问题描述

我想找到两个已知geolocations.Basically之间的角度我想是的，我想直接箭头的尾巴点在我的当​​前位置，箭头是指向一个固定的地理位置。 所以我想，如果不知何故，我能得到这两个geolocations之间的角度，然后propably我就可以这样做。

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.

你们是否有一些建议，做一个更好的方式。任何帮助将是AP preciated。

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