Android - removeUpdates不删除监听器

我一直试图从我的位置管理器中删除位置更新，但即使在removeupdates被调用后，GPS符号也会持续显示。我确保已经传递了正确的侦听器变量名称，并且为侦听器更新执行了代码。我只想找到一次用户的位置。Android - removeUpdates不删除监听器

首先使用LocationManager.NETWORK_PROVIDER时，你不应该看到的GPS标志都没有。

我看你使用谷歌地图的Android API v2的，所以我的猜测是，你把这里的代码之外，你有

map.setMyLocationEnabled(true);

，显示蓝点并不断对其进行更新，同时显示与ActivityMapFragment/MapView 。

是的，这是正确的我已经设置了此代码之外。这将有助于GPS符号出现吗？ – Garbit

@Garbit是的。 'GoogleMap'使用'LoactionClient'在内部使用'LocationManager'与GPS和NETWORK提供者。 –

它是否耗尽电池，我应该在短时间内设置为false？ – Garbit
