How to set unit for Paint.setTextSize()

by

I know this topic is old and already answered but I would like to also suggest this piece of code:

int MY_DIP_VALUE = 5; //5dp

int pixel= (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
                              MY_DIP_VALUE, getResources().getDisplayMetrics());
