禁用所有位置提供程序后，如何在android中获取位置？
[英]How can you get a location in android when all location providers are disabled?
问题描述
LocationManager has a method, getlastknownlocation. 
LocationManager有一个方法getlastknownlocation。 From the documentation this method: "Returns a Location indicating the data from the last known location fix obtained from the given provider. This can be done without starting the provider " 从文档中，此方法：“返回一个位置，该位置指示从给定提供程序获得的最新已知位置修复程序中的数据。 这可以在不启动提供程序的情况下完成 ”
However this method only returns a location if the provider is currently enabled. 但是，如果当前启用了提供程序，则此方法仅返回位置。
I'm a little confused by this, if this method can get a cached location without starting the provider, why would it only return a location if the provider is currently enabled? 我对此感到有些困惑，如果此方法可以在不启动提供程序的情况下获取缓存的位置，为什么仅在当前启用了提供程序的情况下才返回位置？
How can I guarantee a location, however inaccurate and outdated it may be, even if all providers are disabled? 即使所有提供商都被禁用，我如何保证一个位置，无论它有多准确和过时？

You can't. 你不能 If the user hasn't got any location providers enabled, you can't deliver a location. 如果用户未启用任何位置提供程序，则无法传递位置。 If the user hasn't enabled GPS and the user has no Internet connection, you can't get a network-based location (network-based location requires assistance from the server). 如果用户尚未启用GPS且用户没有Internet连接，则无法获得基于网络的位置（基于网络的位置需要服务器的协助）。
Sometimes you just can't tell the user where he is (or was). 有时您只是无法告诉用户他（或曾经）在哪里。
