Each MotionEvent has the current state of all pointers. If you are explicitly tracking one pointer that went down and hasn't gone up, you can map its ID to the index of the pointer data with this: http://developer.android.com/reference/android/view/MotionEvent.html#findPointerIndex(int)
I can't imagine very many cases where you are handling any kind of multi-touch data where you wouldn't be doing something about all active pointers, though.
