推荐答案

是的，这是可以做到。

您可以拨打<一个href="http://developer.android.com/reference/android/location/LocationManager.html#getAllProviders%28%29"><$c$c>LocationManager.getAllProviders()并检查是否 LocationManager.GPS_PROVIDER 包含在列表中。

You can call LocationManager.getAllProviders() and check whether LocationManager.GPS_PROVIDER is included in the list.

仅供参考，我相信所有已发布的Andr​​oid手机都配备了GPS。这不是说Android的似乎是担心，例如：提GPS作为由<返回的设备属性之一href="http://developer.android.com/intl/fr/reference/android/content/pm/PackageManager.html#getSystemAvailableFeatures%28%29"><$c$c>PackageManager.getSystemAvailableFeatures().

Just for reference, I believe all released Android phones come with a GPS. It's not something that Android seem to be worrying about, e.g. mentioning GPS as one of the device attributes returned by PackageManager.getSystemAvailableFeatures().
