How to overlay GLSurfaceView over a MapView in Android?

Question

Hi,

I want to create a simple Map based application in android ,where i can display my current position.Instead of overlaying a simple Image on the MapView to represent the position, i want to overlay the GLSurfaceView on the MapView. But i don't know how to achieve this. Is there any way to do that?. Please anybody knows the solution help me.

You need to create the GLSurfaceView and set its EGLConfigChooser like this:

glSurfaceView.setEGLConfigChooser(8, 8, 8, 8, 16, 0);

then set the format of the holder to translucent

glSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);

and add the GLSurfaceView and the MapView to the Layout

setContentView(glSurfaceView);

addContentView(mapView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));

finally in your renderer you'll need to set the clear color so it is transparent

gl.glClearColor(0, 0, 0, 0);
