I'm creating a simple swipe to delete or edit an item in recyclerView but I have an error :
java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
//I've found this code on Youtube //I've search in all the same problems and I didn't found a solution
