응용 프로그램에서 세 개의 탭을 만들고 각 탭 내에서 하위 활동을 열었습니다. 이제 내가 원하는 것은 탭의 상태를 저장하고 싶다는 것입니다. 예 : TAB-1의 자녀 활동을 위해 TAB-2를 누르면됩니다. TAB-1로 돌아 가면 초기 활동 대신 동일한 하위 활동에서 시작됩니다. 제발 도와주세요탭의 상태를 저장하고 싶습니다.
여기 내 코드 코드가 있습니다.

확인을 내가 원하는, 다음 ... 나는 당신이 달성하고자하는 것을 제대로 이해하지는 "이제 내가 원하는 것이된다 Tab의 상태를 저장하십시오. 예를 들어, TAB-1의 하위 작업을 수행하고 TAB-2 "를 누르십시오. 내가 아는 한 각각의 활동은 내부 상태를 onStop에 저장하고 onStart를 복원하는 책임이 있습니다. – eduyayo
@eduyayo Tab-1의 두 번째 하위 활동에서 Tab-2로 휴가를 전환하면 각 탭 안에 여러 하위 활동이 있습니다. Tab-1로 돌아 오면 두 번째 하위 활동이 초기 하위 활동 – user3679400
대신 동일한 데이터로 표시되어야합니다. 사용자가 tab1을 클릭했지만 여전히 활동 2를 표시합니까? – eduyayo
