I used to give simple ids to Android Views, but lately, I stopped that altogether because of this issue.
Let\'s say I have 2 layouts, one named first_layout.xml>
I too faced same issue, when i copied widget from an one activity to another activity and tried to change ID in copied widget. It prompt a dialog box and i clicked "No (Local Only)". But, i feel no use of that option. it still updated ID in old activity too.
Workaround:
Try to change ID or Attributes through Code(Text Editor) not from Design.
I feel google should address this issue and remove this bug.
