I tried Klaus' SetTextSize code snippet and, on two EditTexts 40dip and 45dip high (Designer + AutoScaleAll), the text become too high.
I think this is due to the fact that the routine does not take into account the upper and lower padding plus an invisible space of the EditText.
Using the code below I get a better resizing (HiddenLabelPart is an empirical value that represents the invisible part of the EditText but it is functional):
