I've never done this, so this is very rough. YMMV. Also, I am assuming
that 42 is a position and that you have no headers or footers on the
list.

Step #1: Confirm that 42 is in the range from
getFirstVisiblePosition() to getLastVisiblePosition(). Do something if
it's not.

Step #2: If it is, subtract 42 from getFirstVisiblePosition() to get a
child index.

Step #3: Call getChildAt() to get the row View at the specified child index.

Step #4: Use stuff like getX(), getY(), etc. to find out where that View is.
