copied!<p>I was stuck on a similar problem until I looked at the documentation and realized that <code>MapView</code> extends <code>ViewGroup</code>, so overlaying a <code>GlSurfaceView</code> actually ends up being pretty trivial. </p> <p><code>MapView.addView(...)</code> and <code>MapView.LayoutParams</code> allow you to some pretty useful things like place a <code>View</code> at a specific <code>GeoPoint</code> on the map.</p> <p>More documentation: <a href="https://developers.google.com/maps/documentation/android/reference/com/google/android/maps/MapView.LayoutParams.html" rel="nofollow">https://developers.google.com/maps/documentation/android/reference/com/google/android/maps/MapView.LayoutParams.html</a></p> <p>Here's what I did:</p> <pre><code>@Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.mapview); MapView map_view = (MapView) findViewById(R.id.map_view); CustomGlView gl_view = new CustomGlView(this); // This is where the action happens. map_view.addView(gl_view, new MapView.LayoutParams( MapView.LayoutParams.FILL_PARENT, MapView.LayoutParams.FILL_PARENT, 0,0, MapView.LayoutParams.TOP_LEFT ) ); } </code></pre> <p>Plus also do what the solution above states. I sub-classed GlSurfaceView, so mine looks slightly different:</p> <pre><code>public CustomGlView(Context context) { super(context); YourCustomGlRenderer renderer = new YourCustomGlRenderer(); setEGLConfigChooser(8, 8, 8, 8, 16, 0); setRenderer(renderer); getHolder().setFormat(PixelFormat.TRANSLUCENT); // Have to do this or else // GlSurfaceView wont be transparent. setZOrderOnTop(true); } </code></pre>

Querying!
