안드로이드 - actionbar tab 도와주세요

actionbar 를 이용하여 4개의 tab을 구현하였습니다. 그리고 하나의 tab안에서 검색버튼을 누르면 새로운 fragment 가 뜨면서 검색한 대상의 정보가 나옵니다. 여기서 에러가 납니다. 새로운 fragment 가 뜬 상태에서 다른 tab클릭시 앱이 죽어버립니다. Error : java.lang.IllegalArgumentException: No view found for id 0x7f070052 (org.jsb.busgod.busgod:id/pager) for fragment BusStop{42a68a00 #7 id=0x7f070052 BusStop} 라도 뜹니다.

메인액티비티 setContent(activity_main.xml) -> TabViewPager -> TabViewPager 의 fragment중 LineNumber 검색버튼 클릭-> InfoFragment 해당 정보 보여 -> 다른 탭 클릭 앱 죽음

같은 container를 사용해서 죽는걸까요? 도와주세요 ㅠㅠ

생깁니다. 그래서 구조를 한번바꿔봤는데요. 지금 TabViewPager가 클래스로 빠져있고 메인엑티비티.xml에 있는 프레임레이아웃에 붙어서 view를 보여주는 구조잖아요. 그리고 InfoFragment 클래스도 프레임레이아웃에 붙어서 보여주고요. 그래서 TabViewPager클래스를 지우고 안에있는 코드를 메인엑티비티 onCreate메서드 안으로 옮겼구요. 메인엑티비티.xml레이아웃에 프레임레이아웃 안에 <viewpager android:id="@+id/xxxx>를 만들어서 탭+viewpager화면은 viewpager에 붙어서 보여주게끔하고 디테일한 정보를 보여주는 프래그먼트들은 프레임레이아웃에 붙어서 보여주게끔 구조를 바꿔봤는데요. 일단 디테일한정보를 보여주는 화면이 보여진상태에서 다른 탭을 클릭시 죽지는 않고 이동은 잘됩니다. 근데 프레임레이아웃이라서 그런지 내용이 겹쳐서보이네요.. 지금 또 다른 난관에 부딪혔습니다.
