有没有办法在 GPS 开启/关闭时收到通知?

Is there a way to be notified when the GPS is switched on/off?

我注意到当设备关闭然后再次打开时，getLastKnownLocation(provider) 为空.所以我想在 GPS 关闭时将位置保存到数据库中.

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PROVIDERS_CHANGED_ACTION 意图.这将在 GPS 提供程序(和其他提供程序)启用/禁用时广播.

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.
