    android:background="@drawable/gradient_animation_list"
    android:orientation="vertical">


    <com.google.android.gms.maps.MapView

public class ContactDetail extends Fragment implements OnMapReadyCallback{
    MapView mMapView;
    GoogleMap mGoogleMap;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.view_contact_hd, container, false);

        mMapView = (MapView) v.findViewById(R.id.mapview);
        mMapView.onCreate(savedInstanceState);
        mMapView.getMapAsync(this); //this is important

        return v;
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mGoogleMap = googleMap;
        LatLng pp = new LatLng(43.1, -87.9);
        mGoogleMap.getUiSettings().setZoomControlsEnabled(true);
        mGoogleMap.addMarker(new MarkerOptions().position(pp));
        mGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(pp, 10));
    }

    @Override
    public void onResume() {
        super.onResume();
        mMapView.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        mMapView.onPause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mMapView.onDestroy();
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        mMapView.onSaveInstanceState(outState);
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mMapView.onLowMemory();
    }
}

Did you know that there is a Wizard for adding this to your app? You can use the Android Live Templates to create this (then you will have most of the work done for you automatically).

Try: File>New>Google>Google Map Activity (you will need to convert to Fragment yourself).

You can add this as an Activity, the convert it to a Fragment, they are similar, and you will be able to see exactly the way to do this. – Booger Dec 27 '18 at 16:54
