制作一个定位对象的Andr​​oid与纬度和经度值 [英] Making a Location object in Android with latitude and longitude values

问题描述

予具有其中一个位置的纬度和经度值存储在数据库中，这是我下载一个程序。

I have a program in which latitude and longitude values of a location are stored in a database, which I download.

我想获得这些坐标之间的距离，和我现在的位置。

I want to get the distance between these coordinates, and my current location.

该位置类有一个简单的方法来找到两个位置的物体之间的距离，所以我想我会做一个定位对象的坐标，然后调用方法。

The Location class has a simple method to find the distance between two Location objects, so I figured I'd make a Location object with the coordinates, then call the method.

有没有一种简单的方法来做到这一点？此外，如果有另外一个可靠的，非常简单的公式，不会弄乱的东西太多了，那工作了。谢谢。

Is there an easy way to do this? Also, if there's another reliable, fairly simple equation that won't clutter things too much, that would work too. Thanks.

（android.location.Location）

(android.location.Location)

您是否在寻找<一href="http://developer.android.com/reference/android/location/Location.html#distanceBetween%28double,%20double,%20double,%20double,%20float%5B%5D%29">this?

这似乎并不真正需要做的地点类，所以可能更适合你

It doesn't seem to require actually making a location class so might be more suited to you
