In OpenGL, you need to write a text renderer. There are several
examples and implementations floating around on the web.
For example, I wrote a class that, given a font and a font size,
generates an atlas texture and stores all of the individual character
locations and metrics for me. I then use that class to draw dynamic
text everywhere in my scene. It took me a few hours to write and
works great. The interface looks like:
public TextRenderer(Context context, GL10 gl, GraphicsConfiguration
graphicsConfig, Typeface tf, float fontSize, int stroke, int
horizSpacing) {}
public void drawTextLine(GL10 gl, int x, int y, char[] text, int
length) {}
I recommend doing something like that.
There are other ways, of course. You can load in the geometry from a
true-type font and render that, though I don't know how easy it will
be in ES to handle the curves and lack of polygon mode.
