double distance;
Location locationA = new Location("point A");
locationA.setLatitude(latA);
locationA.setLongitude(lngA);
Location locationB = new Location("point B");
locationB.setLatitude(latB);
LocationB.setLongitude(lngB);
distance = locationA.distanceTo(locationB);
以上code不工作,我得到0.0公里的距离是多少? 另外在位置类的构造函数,什么是字符串提供商的意思。 在上述$ C $词现在用PointA和PointB作为供应商。
the above code is not working and i am getting 0.0 Km as distance? Also in the constructor of the location class, what does the string provider mean. In the above code i am using PointA and PointB as the providers.
为什么上面的code不工作?
why is the above code not working?
感谢你在前进。

尝试Location.distanceBetween(..)
更新:
如果您是从的GeoPoint越来越纬度/经度,然后他们在microdegrees。您必须通过1e6个繁殖。
If you are getting lat/lon from GeoPoint then they are in microdegrees. You must multiply by 1e6.
