If you want the text outside your OpenGL viewing area, you can place your GLSurfaceView within a layout, with the text in the other controls. This is the simplest option.

To place text within the GLSurfaceView, you either draw the individual characters as 3D ojbects and place them appropriately, or create a bitmap with the text you want and use it as the texture for a flat surface which you draw as part of your scene.
