code to add markers to map using android google maps v2

Question

I have lat&long values from database.how to display markers based on lat &long values using android google map api v2.In original android google maps,we display mark

Answer 1

I'm guessing the issue is that you are multiplying your latitude/longitude values by 1E6 instead of dividing them by 1E6. If your stored values came from GeoPoints, that might be your issue. Otherwise, the way you are adding the Markers is fine and should work.

i.e. the lat/lng values you pass to new LatLng() should look like 45.4,-95.5 NOT 45400000,-95500000

Check out the following code:

//mMap is a GoogleMap and point is a GeoPoint
this.mMap.addMarker(getMarker(point, drawableId))

...

public MarkerOptions getMarker(GeoPoint point, int drawableId)
{
    return new MarkerOptions()
    .position(new LatLng(point.getLatitudeE6() / 1000000.0, point.getLongitudeE6() / 1000000.0))
    .icon(BitmapDescriptorFactory.fromResource(drawableId));
}
