내 MainActivity
에 FragmentA
, FragmentB
및 FragmentC
이라는 세 개의 탭을 추가하고 있습니다.조각의 백 스택이 작동하지 않습니다.
FragmentA
탭에서 목록 조각을 통해 연락처 목록을 채우고이 조각을 백 스택에 추가합니다. 이제 목록 항목 중 하나를 클릭하면 해당 연락처의 세부 조각이 동일한 탭 FragmentA
아래에 표시됩니다. 뒤로 버튼을 누르면 연락처 목록의 목록 조각으로 돌아갑니다.
자세한 내용은 뒤로 단추를 클릭하는 대신에 FragmentB
탭을 클릭하면 잘 작동하는 간단한 텍스트가 표시됩니다. 하지만 이제는 뒤로 버튼을 클릭하면 응용 프로그램을 닫을 수 있지만 목록 조각으로 돌아가서 FragmentB
탭 안에 남아 있으므로 두 조각이 병합됩니다. 내 MainActivity.java
에서

없음이 아니, 아니 활동과 조각과 응용 프로그램을 다루는 M.하지 각각의 탭을 클릭하면'MainActivity'의 UI를 사용하여 새로운 조각을 열고, 단편에 대해서는'onBackPressed'와 같은 것이 없습니다. –
fragmentA에서 fragment B로 전환하는 코드를 보여주세요. 2DFragment 또는 3D Fragment를 클릭 할 때마다 조각의 배낭을 지우라고 제안합니다. 해당 click 이벤트에서 먼저 fragment의 backstack을 pop 한 다음 새로운 fragment를로드하십시오. 확실히 작동 할 것입니다. – GrIsHu
그래, 그게 내가 기다리고있는 것 ... Thnx @ GrlsHu, 잠깐만, 내 코드에 내 게시물에 포함. –
