I have a ListView
with custom rows. When any of these rows is
clicked, the ListView's data is regenerated. I'd like the list to
scroll back to the top when this happens.
I initially tried using setSelection(0)
in each row's OnClickListener
to achieve this but was unsuccessful (I believe because the ListView
loses its scroll position when its data is invalidated - so my call to
setSelection is undone. I still don't understand how the ListView
decides where to scroll to after invalidation, though).
The only working solution I know of was given by Romain Guy here: http://groups.google.com/group/android-developers/browse_thread/thread/127ca57414035301
It involves (View.post
)ing the call to _listView.setSelection(0)
. I
found this to perform quite poorly.
The newly generated list shows up with its scroll location unchanged
and there is a considerable delay before it scrolls back to the top.
Is there any better way to achieve this functionality?
Any help would be much appreciated.
Thanks!
call listView.setSelectionAfterHeaderView();
to scroll to top
I have tried lot but this one worked for me
list.smoothScrollToPosition(0);
I simply use listview.setSelection(0);
Works fine for me.
