LocationManager 最佳实施？
是否建议使用不同的侦听器实现 LocationManager.NETWORK_PROVIDER 和 LocationManager.GPS_PROVIDER ，然后取消注册侦听器 locationManager.removeUpdates(locationListener) ？
因为 GPS_PROVIDER 需要很多时间来返回值，有时甚至不回电？
另外，我们可以有一个 locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);在带有 postDelayed 的处理程序中以避免在没有任何回调的情况下出现死锁？
有人帮忙吗？
提前致谢！！！

Is it advisable to implement both LocationManager.NETWORK_PROVIDER and LocationManager.GPS_PROVIDER with the differenct listener and then unregister the listeners locationManager.removeUpdates(locationListener) ?
Because GPS_PROVIDER takes lot of time to return the values and sometimes doesn't even gives a call back?
Also, we can have a locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); in handler with a postDelayed to avoid a deadlock in case there aren't any callbacks?
Any help by anyone?
Thanks in advance!!!

嗯，据我所知，locationManager.getLastKnownLocation 会立即返回，所以您不应该看到任何死锁？
如果您确实需要管理自己的 LocationListener，建议首先注册一个 Network-One 和两个 GPS-One。使用网络监听器接收第一个位置（粗略）。配置一个 GPS 位置侦听器以接收所有 GPS 更新。一旦位置足够准确，切换到托管 GPS 位置监听器，该监听器仅每 x 秒和 x 米差接收更新。请参阅http://developer.android.com/guide/topics/ location/obtaining-user-location.html 了解更多示例。
如果您想在地图上显示位置，请尝试 MyLocationOverlay。它为您完成这一切。
Hm afaik locationManager.getLastKnownLocation returns instantly, so you should not see any deadlocks?
If you really need to manage your own LocationListeners, it is advisable to first register a Network-One and a two GPS-ones. Use the network-Listener to receive a first location (rough). Configure one GPS-Location-listener to receive all GPS-Updates. Once the location is accurate neough, switch to a managed GPS-Location-Listener, that only receives updates every x seconds and x meters diff. See http://developer.android.com/guide/topics/location/obtaining-user-location.html for more examples.
If you want to display the location on a map, try MyLocationOverlay. It does all that for you.
理想情况下，这个问题将不再有效，因为谷歌最终发布了新版本的位置侦听器，这将更有效地解决这个问题。

Ideally this question wont be valid anymore, since Google finally released newer version of location listeners which would take care of this more effectively.
