以编程方式启用GPS（无需导航到位置设置）

Question

如何通过点击弹出屏幕上的“开启”选项（无需导航到位置设置），以编程方式启用GPS，因为它确实发生在官方Google地图应用中？

Answer 1

The Google Maps app is using what is now available to us as SettingsApi the Play Services SDK. You can use SettingsApi to inquire as to whether your desired LocationRequest can be fulfilled with whatever location providers are enabled. If it cannot be fulfilled, and Play Services thinks that the user can change this, you can ask for the dialog that you see Maps display pop up.

Using SettingsApi is not especially simple. Here a sample app for that. Using ACTION_LOCATION_SOURCE_SETTINGS , as suggested in Laurenswuyts' answer, is much simpler to implement.

Answer 2

That's because they are using the Settings API in the play services as described in Commonsware's answer, which is a bit difficult. You are better off with the "old" method:

Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
