How to get ascender/descender and x height for a given font

Question

I need to get a ascender/descender and x-height..

By using following code I can find the descender and the total height:

descender_height = paint.des         


        

Answer 1

This is what worked for me:

Paint.FontMetrics fm = paint.getFontMetrics();
int totalHeight = (int)(fm.bottom - fm.top + .5f);
