Question

i`m looking for way to position expandableListView group on top, when expanded.
I tried onGroupExpand, or in performItemClick of ExpandableListView.

setSelectedPositionFromTop(int, int), partialy works, but if it starts in a time when system starts it’s own scroll, than list is overscrolled, and group is out of screen.

Sorry for messy description, but it’s hard to say without showing exactly what i need.

Answer 1

I have solution to this problem. It’s not gentle one, but it works quite fine.
Expandable listView messures is it should move by child number. It seems, that system thinks that child is same height as parent(group), so if you put different size child it will cause problems with auto scrolling list.

My solution was to trick list to think that it has more children.
If my child is twice as big as group, i just return information that group has 2 children. Now, since it is data constructed list, i make check on my data, is there a data for 2 childs, or only 1, if i don’t have data for second child, i know that i can put 0 height view as second child.

It worked fine when i had to make List with small group, and than with 1 big child.

Since there was no answer to my question, i post this one, it may help someone.
