You can use the below code. With the below code it will ask to turn the GPS on .
public class Activity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks,

private Location mLastLocation;
// Google client to interact with Google API
private GoogleApiClient mGoogleApiClient;
// boolean flag to toggle periodic location updates
private boolean mRequestingLocationUpdates = false;
private LocationRequest mLocationRequest;
// Location updates intervals in sec

.addLocationRequest(mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY));
result =
LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override

Here API <= 21 gps permission will be granted automatically(if you have defined permission on manifest) and for marshmallow and above you need to ask for runtime permission(also add permission in manifest) but to turn on GPS after permission granted you can use the above code.
With this code one alertbox comes up and ask to turn on the GPS(if not active). So you can directly turn on GPS with the above code.
Hope this help you.
Cheers!!
