Child view (bubble) positioning issue when map is rotated.

[GoogleCodeExporter]

1. Rotate the map: mapView.setMapOrientation(90.0f);

2. Add a child view to the MapView, using MapView.LayoutParams:
MapView.LayoutParams lp = new MapView.LayoutParams(
    MapView.LayoutParams.WRAP_CONTENT,
    MapView.LayoutParams.WRAP_CONTENT,
    position, MapView.LayoutParams.BOTTOM_CENTER, 
    offsetX, offsetY);
mapView.addView(childView, lp);

=> At this stage, the child view position is OK. 

3. Pan the map manually on screen. 
=> The child view position is moving, but not in relation with the mapview. 

The issue is probably in MapView.onLayout: in this method, map orientation is 
never taken into account (as done for instance in rotateTouchEvent).

This is definitely an issue and tough to fix. I was playing around with a 
solution that would manipulate the added view's translateX/Y parameters that 
was moderately successful but still needed work.

Hi Marc, 

I found a working solution. 

See: 
https://drive.google.com/file/d/0B_8VOmRyW664QTJ3bE0zZjFZbGc/edit?usp=sharing

Basically: 

- In onLayout, it applies rotation of children geoPoint around the center of 
the map (=> this rotation was missing anyway in this method). 

- In scrollTo, call onLayout to force layout computation of children. It seems 
OK (zoom, pan, animateTo), but I'm not sure this is the best place to really 
cover all possible cases.
