I found the correct way of doing this (This code is in the Activity class)
view = new MyGLSurfaceView(this, gameHandler);
editBox = new EditText(context);
editBox.setText("Hello Matron");
view.setRenderer(new OpenGLRenderer(gameHandler));
setContentView(view);
addContentView(editBox, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));The key is using addContentView method on the Activity class to add the editBox on top of the GLSurfaceView.
Hope this helps some googlers :)
Thanks! Ash
