Did I miss something? 回答1: After a bit a searching, I couldn't find such an option. I finally removed the location pin, and added a

问题 I am trying to get a GeoPoint for -23.4456 by 45.44334 What values do I pass into the constructor of the GeoPoint as it take Ints only. 回答1: GeoPoint coordinates are based in microdegrees (degrees * 1e6) -- written here float lat = -23.4456f; float lng = 45.44334f; GeoPoint gp = new GeoPoint((int)(lat * 1E6), (int)(lng * 1E6)); 回答2: rather than repeating the math throughout my app, i prefer to create a LatLonPoint: private static final class LatLonPoint extends GeoPoint { public LatLonPoint
