Android Question how to delete record from customlist view based on item value

[Makumbi]

Please i have this code below to i wanted to use so that i can delete a recode on the item value say date for example because in my log i see a different value please help

    Log("ItemLongClick " & Index)
    Log(Value)
    Msgbox2Async("Do you to delete this Message?", "Delete", "Confirm", "", "Cancel", Null, True)
    Wait For Msgbox_Result (Result As Int)
    If Result <> DialogResponse.POSITIVE Then Return
    clvMessages.RemoveAt(Index)

so the delete also happens in my sql lite database too

    oSQL.ExecNonQuery("CREATE TABLE tbl_Messages (Id INTEGER PRIMARY KEY, Timestamp INTEGER, ChatClientName TEXT,  Message TEXT, IOflag TEXT)")
