How to use MapView in android using google map V2?

I want to show a map in on of my activity.

In google map V1 we use -

 <com.google.android.maps.MapView
        android:id="@+id/mapview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:apiKey="@string/api_map_key"
        android:clickable="true"
        android:enabled="true" />

and extend the activity by using MapActivity class.

In Versing 2 it uses Fragment instead of mapview and have to extend activity by FragmentActivity instead normal Activity. ex-

<fragment
            android:id="@+id/map"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            class="com.google.android.gms.maps.SupportMapFragment" />

Now Can I use Same way to create mapview instead of Fragment using version 2 .()

Can anyone use MapView using V2?

SomeFragment.java

public class SomeFragment extends Fragment implements OnMapReadyCallback{
 
    MapView mapView;
    GoogleMap map;
 
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.some_layout, container, false);
 
        // Gets the MapView from the XML layout and creates it
        mapView = (MapView) v.findViewById(R.id.mapview);
        mapView.onCreate(savedInstanceState);
 
    
        mapView.getMapAsync(this);
        
 
        return v;
    }
 
   @Override
   public void onMapReady(GoogleMap googleMap) {
       map = googleMap;
       map.getUiSettings().setMyLocationButtonEnabled(false);
       map.setMyLocationEnabled(true);
       /*
       //in old Api Needs to call MapsInitializer before doing any CameraUpdateFactory call
        try {
            MapsInitializer.initialize(this.getActivity());
        } catch (GooglePlayServicesNotAvailableException e) {
            e.printStackTrace();
        } 
       */
        
        // Updates the location and zoom of the MapView
        /*CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(43.1, -87.9), 10);
        map.animateCamera(cameraUpdate);*/
        map.moveCamera(CameraUpdateFactory.newLatLng(new LatLng(43.1, -87.9)));

    }

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


    @Override
    public void onPause() {
        super.onPause();
        mapView.onPause();
    }
 
    @Override
    public void onDestroy() {
        super.onDestroy();
        mapView.onDestroy();
    }
 
    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mapView.onLowMemory();
    }
 
}

</LinearLayout>

Solution 2:

More complete sample from here and here.

Or you can check out my layout sample. p.s no need to put API key in the map view.

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">

    <com.google.android.gms.maps.MapView
            android:id="@+id/map_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="2"
            />

    <ListView android:id="@+id/nearby_lv"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:background="@color/white"
              android:layout_weight="1"
            />

</LinearLayout>
