我在23个以下设备中获得当前位置,但在23个仿真器设备中获得(0.0,0.0)纬度和经度.
编辑 目前我正在使用融合位置提供程序获取当前位置
public class ContactUsFragment extends Fragment implements ConnectionCallbacks, OnConnectionFailedListener, LocationListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i("TAG", "OnCreate Called");
locationManager = (LocationManager) getActivity()
.getSystemService(Context.LOCATION_SERVICE);
buildGoogleApiClient();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
final Bundle savedInstanceState) {
// Inflate the layout for this fragment
view = inflater.inflate(R.layout.fragment_contact_us, container, false);
Log.i("TAG", "OnCreateView Called");
setComponants(view); // **** Method For Set Componants Of Layout
这是点击它的Map Image我想获得当前位置并将其传递给设备的Native Google Map应用程序以导航到目标位置
mapImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i("TAG", "On ImageView Click");
if (Build.VERSION.SDK_INT >= 23) {
if (checkPermission(Manifest.permission.ACCESS_FINE_LOCATION, getActivity().getApplicationContext(), getActivity())) {
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
navigateToGoogleMap();
} else {
showSettingsAlert();
}
} else {
requestPermission(Manifest.permission.ACCESS_FINE_LOCATION, PERMISSION_REQUEST_CODE, getActivity().getApplicationContext(), getActivity());
}
} else {
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
navigateToGoogleMap();
} else {

}
}
}
});
return view;
}

*当我在下面的API23设备中使用时,此代码正常工作,但当我尝试使用marshmallow设备时,它会给出当前位置0.0,0.0*
