Android Map API-更改缩放级别会导致标记位置不正确

Question

Sorry if this was asked before.. it seems so obvious problem but could not find any reference.

When adding marker to the map - not even custom one, just plane marker, and zooming in/out, the marker image "floats" around to different positions, even to different states! I am passing the proper Double to the lat/long etc.. zooming all the way in gets you to the correct place.

Looking at Google's own services such as Google+ location sharing, it seems to work fine for them.. so not sure what to make of it.. are they re-calculating the anchor for each zoom level? hmm

Appreciate any help! Thanks, Udi

Answer 1

I had the same problem adding marker.anchor(0,0); Fixed the problem.

Answer 2

I have same problem when adding marker to google map, the problem is wrong bitmap when try to convert and resize drawable resource, just use this:

    Marker marker = mMap.addMarker(new MarkerOptions()
    ...
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_merchant_location)));
