와는 TextView

Results.Java

나의 첫번째 문제는 내가 쿼리를 제출할 때, 두 번째 Fragment (fragment_results)는 "사라"정상 ListFragment 것이있다 (activity_main)가 나타납니다. 이 문제를 해결하는 방법을 모르겠습니다. 두 번째 문제는 Search Widget을 닫거나 닫을 때 OnCloseListener이 두 번째 Fragment (fragment_results)을 제거하고 ListFragment (activity_main)을 표시 할 것으로 예상됩니다. OnCloseListener에 이것을 구현했지만 아무 일도 일어나지 않습니다. 또는 OnCloseListener을 다른 것과 혼동하고 있습니까?

내가 도와 주시면 기쁠 것입니다.

첫 번째 문제는 onClick in xml을 메뉴 항목으로 설정하는 것입니다. 이것은 틀리며 전화하지 않습니다. onItemMenuSelected를 구현하려면 https://developer.android.com/guide/topics/ui/menus.html#RespondingOptionsMenu

을 사용하십시오.
