Android Menu duplication fixed with clear but it clears the parent activity menu

Question

I have created different fragment and populated some menu based on the fragment. I was getting duplicate menu items so I used clear as suggested various stackoveflow posts but the problem is when I use clear in fragment it also clears the main activity menu items.

Answer 1

Activity and all fragments inside it use the same Menu instance. So no matter where you call clear() method, all items will be deleted. Menu items that are used across all child fragments should be created inside Activity. Fragment-specific options should be created inside corresponding fragment. Ideally you should not have duplicated menu items. If two fragments have same menu item but third doesn't -- prefer create menu item inside every fragment but not single menu item inside activity. With this approach you will not get duplicates. But If you want just to delete duplicates you can use menu.removeItem(itemId) method. Also you can hide redundant item with menuItem.setVisible(false).
