GeoPointis only for Maps V1. To draw lines in Maps V2, you would add a Polylineto your GoogleMap:
GeoPoint仅适用于地图 V1。要绘制在地图V2线，你会添加一个折线给您GoogleMap：
PolylineOptions line=
new PolylineOptions().add(new LatLng(40.70686417491799,
-74.01572942733765),
new LatLng(40.76866299974387,
-73.98268461227417),
new LatLng(40.765136435316755,
-73.97989511489868),
new LatLng(40.748963847316034,
-73.96807193756104))
.width(5).color(Color.RED);
map.addPolyline(line);
(from this sample app, described in detail in this book)
