是的，你可以检查以下是代码:

public boolean isGPSEnabled(Context mContext) 
{
    LocationManager lm = (LocationManager)
    mContext.getSystemService(Context.LOCATION_SERVICE);
    return lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
}

在manifest文件中的权限下:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

是的，你可以检查以下是代码:

public boolean isGPSEnabled(Context mContext) 
{
    LocationManager lm = (LocationManager)
    mContext.getSystemService(Context.LOCATION_SERVICE);
    return lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
}

在manifest文件中的权限下:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

在我看来，这个if子句很容易检查位置服务是否可用:

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if(!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) && !locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
        //All location services are disabled

}

public class LocationUtil {
private static final String TAG = LocationUtil.class.getSimpleName();

public static LocationManager getLocationManager(final Context context) {
    return (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
}

public static boolean isNetworkProviderEnabled(final Context context) {
    return getLocationManager(context).isProviderEnabled(LocationManager.NETWORK_PROVIDER);
}

public static boolean isGpsProviderEnabled(final Context context) {
    return getLocationManager(context).isProviderEnabled(LocationManager.GPS_PROVIDER);
}

// Returns true even if the location services are disabled. Do not use this method to detect location services are enabled.
private static boolean isPassiveProviderEnabled(final Context context) {
    return getLocationManager(context).isProviderEnabled(LocationManager.PASSIVE_PROVIDER);
}

public static boolean isLocationModeOn(final Context context) throws Exception {
    int locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);
    return locationMode != Settings.Secure.LOCATION_MODE_OFF;
}

public static boolean isLocationEnabled(final Context context) {
    try {
        return isNetworkProviderEnabled(context) || isGpsProviderEnabled(context)  || isLocationModeOn(context);
    } catch (Exception e) {
        Log.e(TAG, "[isLocationEnabled] error:", e);
    }
    return false;
}

public static void gotoLocationSettings(final Activity activity, final int requestCode) {
    Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
    activity.startActivityForResult(intent, requestCode);
}

public static String getEnabledProvidersLogMessage(final Context context){
    try{
        return "[getEnabledProvidersLogMessage] isNetworkProviderEnabled:"+isNetworkProviderEnabled(context) +
                ", isGpsProviderEnabled:" + isGpsProviderEnabled(context) +
                ", isLocationModeOn:" + isLocationModeOn(context) +
                ", isPassiveProviderEnabled(ignored):" + isPassiveProviderEnabled(context);
    }catch (Exception e){
        Log.e(TAG, "[getEnabledProvidersLogMessage] error:", e);
        return "provider error";
    }
}

}

使用isLocationEnabled方法检测位置服务是否已启用。

https://github.com/Polidea/RxAndroidBle/issues/327#页面将提供更多信息为什么不使用被动提供程序，而是使用定位模式。

我使用这样的方式NETWORK_PROVIDER，但你可以添加和GPS。

LocationManager locationManager;

在onCreate中

   isLocationEnabled();
   if(!isLocationEnabled()) {
        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
        builder.setTitle(R.string.network_not_enabled)
                .setMessage(R.string.open_location_settings)
                .setPositiveButton(R.string.yes,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
                            }
                        })
                .setNegativeButton(R.string.cancel,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                dialog.cancel();
                            }
                        });
        AlertDialog alert = builder.create();
        alert.show();
    } 

检查方法

protected boolean isLocationEnabled(){
    String le = Context.LOCATION_SERVICE;
    locationManager = (LocationManager) getSystemService(le);
    if(!locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
        return false;
    } else {
        return true;
    }
}

要检查网络提供者，你只需要将传递给isProviderEnabled的字符串更改为LocationManager。NETWORK_PROVIDER如果你检查GPS提供者和网络提供者的返回值-两个false都表示没有位置服务
