Answer 1

It is not about support as answered abowe. The cause of issue is that GLSurfaceView is not on the view level. In short: for you case you have GLSurfaceView at the first level, then other views with holes in views abowe GLSurfaceView (this handles by windows manager, and it dosent matter where you put GLSurfaceView on xml, it will be on first level in any case and others views on next level)

So, what you need is to force view update, and there is work around: you should put scroll with GLSurfaceView or (RecyclerView with GLSurfaceViews) "between" two FrameLayouts. something like this:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout   
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent" >

     <ScrollView
        android:fillViewport="true"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

       ---- here should be linear layout with your glView, or RecyclerView instead if required ----
     </ScrollView>

   --- this frame also required: ---
   <FrameLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="@android:color/transparent" />

</FrameLayout>

Answer 2

You may use below lines for removing over scrolling :

glView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
glView.setZOrderOnTop(true);
glView.setZOrderMediaOverlay(true); 

And for removing black background :

linearLayout.setBackgroundColor(context.getResources().getColor(R.color.white));
linearLayout.addView(glView);

Also add below line in your manifests file :

android:hardwareAccelerated="true"

Hosting SurfaceViews inside ScrollView (or Listview, etc.) is currently not supported.
