inv_gps.of_getcurrentposition( lstr_coordinates)
lwei=lstr_coordinates.dec_latitude
ljin=lstr_coordinates.dec_longitude

我用上面方法得到 经度和纬度， 但我点击多次，每次得到的值都不一样，偏差比较大，定位不准，怎样可以准确,不要变来变去？还有我现在这样是得到经度和纬度，但怎样可以得到具体的地点呢？如果不行那或者哪个网站可以通过经度和纬度查询到地址？ 谢谢

你好，

请参考附件PB 2019 R3的案例.
不需要安装地图软件，需要安装google play service, 国产手机可能不支持google play service。
你可以调用Google提供的API来进行经纬度和地址的转换，请参考。

是安卓手机，11版本，是不是手机上要安装地图软件，比如百度地图等呀？ 还有能不能发个实际的例子学习下，谢谢

你好，

你手机的OS版本是什么？其他手机有这个问题吗？这个跟网络环境有关系，同一位置，不同网络(WIFI,移动，电信等，2G/3G/4G/5G等)可能返回不同值，你可以有用其他定位app是否有同样问题。

经纬度和地址的互相转换，eon_mobile_mapex对象有提供函数of_coordinatetoaddress/of_addresstocoordinate支持，具体请参考。
