Hi, I am trying to develop a Android Google Map application, which is
basically Gmap with my own marker geo layer. Since android.com is
banned in China, I have to search support from Google user groups. I
have no idea which groups I should call for help, android group or
google map group. Anyway here is my questions:

I am working on Android SDk1.5. I want to reproduce the floating
buttons presented in android Google map, which stands for three
buttons: ZoomControl (left), FocusChange (middle), and ListControl
(right). (Pls check ref1. ) I checked some open source projects, if
designer can place these controls in the layout.xml with relative
layout, to place them over (on the top of) the mapview. It may solve
some problem, however in the SDK1.5' add-on gmap jar, the
getZoomControl is discarded. I can only setBuiltInZoomControl(true) to
enable the builtin zoomcontrol. By default, the "BuiltIn" Zoom Control
is placed at Bottom/Center. (Pls check ref 2.) I have no idea how to
relocate the "BuiltIn" Zoom Control to the left as native GMAP does.

So:

How to relocate the BuiltIn Zoom Control ?
How to add addtional custom control (buttons/overlays) with
BuiltInZoomControl ? What functions should be overriden for the detail
implementaiton, Such as synhcorization with the visibility?
I am appreciated if the answer can be offered with code snippet or
references to any internet site.
