Question

I have a ListView with quite “high” rows. The rows have quite complex layouts, and I’d like to get ListView to scroll to exactly a child element of a row. Is this possible?

I’ve only found .smoothScollToPosition(), but I can only specify a whole row in that. I need something more precise, to e.g. scroll to a child element in the middle of a row.

Thanks.

Answer 1

Take a look at the ListView method smoothScrollToPositionFromTop (inherited from AbsListView)

Smoothly scroll to the specified
adapter position. The view will scroll
such that the indicated position is
displayed offset pixels from the top
edge of the view. If this is
impossible, (e.g. the offset would
scroll the first or last item beyond
the boundaries of the list) it will
get as close as possible. The scroll
will take duration milliseconds to
complete.

You’ll be responsible for calculating the offset required to land in the middle of a row – that is beyond the scope of your question as it stands.
