Android, opengl, move glsurfaceview

I have created glsurfaceview in xml file, I'd like to change X,Y of this glsurfaceView when the button is pressed. I have onSurfaceChanged() method and there are x,y variables. can I call this method for chane glsurfaceview position? if I can, how can I do it, or how can change position?

No, you can't, because onSurfaceChanged (GL10 gl, int width, int height) serves as an event. It is called by the OpenGL ES subsystem when your surface size has already changed. Therefore, it is for overriding and performing certain typical operations (as detailed here) when the size of your surface has already changed.

Since GLSurfaceView is a SurfaceView descendant and is part of the View hierachy, you can use the usual positioning methods (such as setX()) to set its position (but don't forget about screen- and density-independence that you should ensure in your Android applications).

As a side note: I don't know your application architecture and details, but when there is a need to re-position a GLSurfaceView, then usually there is an equivalent solution/workaround to the same problem that doesn't require repositioning.
