The Listmodel is not efficient enough
When the ListElement amount exceed 600, the Listmodel seems slow.
[edit: fixed typo in title, eddy]
Can you elaborate on your use case? Some code on how you are using the ListModel?
If you give more information, it's easier for us to help you.
I need a list with such feature
- The data background should be dynamic increase from from the bottom
- The items in view should be grouped by category
- The group title item could be expanded/collapsed to show/disappear the items
- The highlighted item could be adjust when expanded/collapsed occurs
It could be very fast at the very beginning, however when the data about exceed 600, it always costs about 1 second on my device(An CortexA8 device).
At that period, I nearly could not move my mouse at all.
