Answer 1

This is because it is the same View instance that is being used now that the first item is out of view.

For this purpose you will need to implement your own (Base)Adapter and store the information there as to which items should be strike through.
Then set the correct paint flags in the getView method as the views move in and out of view.

Answer 2

This is happening because of a view is reused. You need to store the position OR id of that object and provide stroke through effect accordingly. Hope it will help you out. For code reference or help please refer below link.It will definitely help you out
