If I remember correctly you should be able to adapt this

Overlapping Views in Android

to your needs

(relative layout and android:background="#0000")

since GLSurfaceView is a View it should work.

I fixed it. using

    gLSurfaceView.setEGLConfigChooser(8,8,8,8,16,0);
    gLSurfaceView.setRenderer(this);
    RelativeLayout rl = new RelativeLayout(this);
    BgLayout bgl = new BgLayout(this);
    gLSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
    gLSurfaceView.setZOrderOnTop(true);
    rl.addView(bgl);
    rl.addView(gLSurfaceView);
