I have ListView at my fragment where I try to select some items by LongClick. At my screen I can see 8 items ( on another smartphone I can see 6 items.) When I have a lot items in my ListView ( for example 23) and I LongClick on a first item as a result I see changed image, but if I scroll down I can see that 10 and 19 items has changed image too ( like they has been checked ). At the another smartphone after LongClick the first item I see change 8 and 16 too and etc). As you can see I get change ListView items images just after the same numbers of items as can present my smartphone. The real status of "additional" items not changed, only their image view. It's the strange behavior of ListView, which duplicate changing image of items view at each group ( group means the number ListView items a multiple the number of items which the smartphone can display simultaneously)
Whats wrong in my code or how to avoid this unexpected behavior of ListView? Thanx
