广播接收器,GPS状态? [英] Broadcast receiver for GPS state?
问题描述
有没有办法当GPS开启被通知开/关?
Is there a way to be notified when the GPS is switched on/off?
我注意到,当设备关闭了再打开,getLastKnownLocation(供应商)为空。所以,我要救当GPS关闭到数据库的位置。
I noticed that when the device is switched off an then on again, getLastKnownLocation(provider) is null. So I want to save the location when the GPS is switched off to a database.
推荐答案
注册一个BroadcastReceiver来监听LocationManager的<一个href="http://developer.android.com/reference/android/location/LocationManager.html#PROVIDERS_CHANGED_ACTION"相对=nofollow> PROVIDERS_CHANGED_ACTION 意图。当GPS提供商(和其他供应商)启用/禁用这将播出。
Register a BroadcastReceiver to listen for the LocationManager's PROVIDERS_CHANGED_ACTION Intent. This will be broadcast when the GPS provider (and other providers) is enabled / disabled.
