我想在我的应用程序中获取经度和纬度的值，但是我的问题是Iam获取带有值的负号。虽然值是正确的，但不知道为什么要使用值获取负号。< / p>
java类的代码：

纬度表示赤道以北和以南。经度表示本初子午线的东西方。
纬度为负表示赤道以南，经度为负表示本初子午线以西。
位置数据通常以纬度和经度对的形式表示，如下所示：
37.427619，-122.166972 [斯坦福大学胡佛塔]
下面的简单框架可以帮助您解码位置对。
+ + : North and East
+ - : North and West
- - : South and West
- + : South and East
请注意，该框架的中心点是几内亚湾本初子午线与赤道相交的0,0。

LatLong可以为正也可以为负。
示例：
44.389061321549, -114.659369144245是美国爱达荷州的有效LatLong。
只需复制您的LatLong，然后将其粘贴到Google Maps的搜索框中，即可获得LatLong的确切位置。
