Using GLSurfaceView class with android xml layouts

Question

I want to make use of the android xml layouts. I have put a glSurfaceView in a frame layout to use in conjunction with a linear layout like so...

Answer 1

Just reference your own class (with full packagename) in the xml, the same way you reference android.opengl.GLSurfaceView. Make sure that your subclass implements the proper constructor, and passes the context & attributes to the parent:

public MyGLSurfaceView(Context context, AttributeSet attrs)
{
   super(context, attrs);

Then you can fetch it using findViewById:

MySurfaceView glSurfaceView = 
             (MySurfaceView)findViewById(R.id.surfaceviewclass);

That should do the trick.

Answer 2

If everything corect, like you write in the xml-layout, the full Path to the Glsurfaceview-class : (and classname)

it works only if the class, GLSurfaceView, written in a own File. in this file for shure, the construktors need to be written correctly.

i read about ,1 constructor for xml-refer, and one for comunication between classes. constructor for xml-refer, and one for comunication between classes, can be found, if written correcly, inside GLSurfaceView . GLSurfaceView, is where you set the Renderer, set it in the the xml constructor, must be the only way, it works fine. (shown in anwer 1)

xml-constructor:

public MyGLSurfaceView(Context context, AttributeSet attrs) { super(context, attrs); setEGLContextClientVersion(2);
renderer = new Renderer(context); setRenderer(renderer);

If you some of this peoples, who cant get SurfaceView work, in xml-layout ore, who buy this book from Apress - Beginning 3D- Game-Development. dont be angry ore hurt yourself. At page 44-45 it be written, in one file. Write GLSurfaceView, like in my answer, in own file. Renderer is own file, where: onSurfaceCreated, onSurfaceChanged, onDrawFrame..can be found And The MainActivity
