Hi:
everybody, I want to update Galley items, like change or remove
some items, or add new items, after I update my items ArrayList, the
Gallery will not update it immediately, I must drag it out of screen,
then drag it back, the update item will displayed, I tried invalidate
() method, I want use invalidate() to redraw Gallery, but it doesn't
work, I don't know why.
Anybody could give some suggestion?
Thanks.
