How to draw an overlay on a SurfaceView used by Camera on Android?

SurfaceView probably does not work like a regular View in this regard.

Instead, do the following:

1. Put your SurfaceView inside of a
   FrameLayout or RelativeLayout in
   your layout XML file, since both of
   those allow stacking of widgets on
   the Z-axis
2. Move your drawing logic
   into a separate custom View class
3. Add an instance of the custom View
   class to the layout XML file as a
   child of the FrameLayout or
   RelativeLayout, but have it appear
   after the SurfaceView

This will cause your custom View class to appear to float above the SurfaceView.
