Question

i have a GLSurfaceView, that has a texture that i need to change when i click on a button.
How can i do this on android.
I managed something with:

            Intent intent = getIntent();
            finish();
            startActivity(intent);

But i need to refresh only openGL and not the whole program

Answer 1

this is NOT the way to refresh your view. you need to use the invalidate function.
