Ejaz Asghar commented on FLEX-33611:
------------------------------------
@OmPrakash Muppirala ,
I'm able to improve the performance using iconItemRenderer , i was previously
extending labelItemRenderer and adding my BitmapImage using Gorup to sprite. So
this problem is fixed, however i had to spend 4 hours to understand the
implementation of iConItemrenderer, for example it is not clear how to change
the index (setChildIndex) of the bitmapImage and other several questions,
perhaps an article explaining how bitmaps r handled in IconRenderer and how can
we customize their rendering order, partial opacity to each individual bitmap
etc can b published on apache blog after the release. Otherwise it vl b really
difficuilt for new users to customize or add more bitmaps to IconItemRenderer
and still make it perform better.
You can close this issue, Thanks

> Hi,
> my app which shows 100 160x160 images on a tile layout works great on iOS,
> but on many devices even Nexus 7 or Nexus 10 scrolling is very very slow. We
> cant launch the product with this. However vertical layout is much much
> better on same devices.
> It looks like TileList require a rewrite for mobile devices. I even specified
> fixed values to columns, and tile sizes which are all 160x160 (no variable
> heights/widths). but still its pretty slow.
> I'd appreciate if you guys incorporate a mobile friendly Tilelayout for Flex
> 4.10, which provide fixed sizes of tiles and scroll as fast as vertical
> layout.
>
> Thanks
