Android：onCreateOptionsMenu在一个片段中膨胀所有其他片段中的菜单

Question

To begin with, I have a fragment-based app. On the first fragment user sees recyclerview and I'm calling onCreateOptionsMenu() which makes menu with a searchview . The problem is, when I switch to other fragments I also see this menu. And if another fragment has its own menu, inflater adds items from both menus. As a result, I see my searchview -icon everywhere. Can you please explain me, what am I doing wrong?

Try to override onCreateOptionsMenu() in all your fragments and call super.onCreateOptionsMenu() before anything else. Alternatively , use menu.clear() in those other fragments.
