How can I get position in google map?

Question

I want to find position of location(with latitude and longitude).

I try to get the (latitude, longitude) of left-top and right-bottom points of map and lerp to calculate the position.

However, I don't know coordinate of left-top and right-bottom points. How can I get or calculate them?

Answer 1

You are looking for the VisibleRegion class.

From a MapFragment you can use:

VisibleRegion visibleRegion = getMap().getProjection().getVisibleRegion();

Answer 2

Center:

map.getCameraPosition().target;

Bounds:

LatLngBounds curScreen = map.getProjection().getVisibleRegion().latLngBounds;

Where you then access left-top and right-bottom points using:

curScreen.northeast

and

curScreen.southwest
