Basically, I have a slight problem with interprating a remove feature. The user clicks on a button that is in the ListView, a PopupMenu is then promted and displays "Unfriend", "Unfollow", "Messgae" and "Cancel". When the user clicks on "Unfriend", the Friend that the user wants to unfreind is then removed.
I have a problem with three things; Searching and Removing(to a slight degree):
1 When the User uses the search feature, the Unfriend option becomes non-usable. If the user clicks unfriend. It does nothing...
2 When the User attempts to search for a user than they have previously removed as a friend. It actually displays that user in the search results.
3 When a User removes a friend, and then searches for another friend to remove. It adds all of the previously removed friend back into the list.
There must be something I am doing wrong? Maybe I'm storing data and then re-using it to a certain degree somewhere else down the line?
I DO NOT get any exceptions from this code. It actually runs with minor faults.
