GoogleMap map;

TextView txt;

String[] mapTypes={"Normal","Hybrid","Satellite","Terrain"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
            .getMap();

    txt=(TextView)findViewById(R.id.textView1);

//to set map Type
    map.setMapType(GoogleMap.MAP_TYPE_NORMAL);

//To set the marker on map on specific location using lat lag
    // latitude and longitude
    double latitude = 18.520430300000000000;
    double longitude = 73.856743699999920000;

    // create marker
    MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("My Location");

    // change color to the marker icon
    marker.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_CYAN));

    // adding marker
    map.addMarker(marker);

    // Create an array adapter to populate dropdownlist 
    ArrayAdapter adapter =new ArrayAdapter(getBaseContext(), android.R.layout.simple_spinner_dropdown_item, mapTypes);

    /** Enabling dropdown list navigation for the action bar */
    getActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);

    /** Defining Navigation listener */
    ActionBar.OnNavigationListener navigationListener=new ActionBar.OnNavigationListener() {

        @Override
        public boolean onNavigationItemSelected(int itemPosition, long itemId) {
            Toast.makeText(getBaseContext(), "U Select : "+mapTypes[itemPosition], Toast.LENGTH_SHORT).show();
            if (mapTypes[itemPosition].equals("Normal")) {
                map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
            }
            else if (mapTypes[itemPosition].equals("Hybrid")) {
                map.setMapType(GoogleMap.MAP_TYPE_HYBRID);
            }
            else if (mapTypes[itemPosition].equals("Satellite")) {
                map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
            }
            else if (mapTypes[itemPosition].equals("Terrain")) {
                map.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
            }
            return false;
        }
    };

    // Setting dropdown items and item navigation listener for the actionbar 
    getActionBar().setListNavigationCallbacks(adapter, navigationListener);

}
