안드로이드 텍스트 뷰는/두 배로 미러/응용 프로그램

Question

이 후 발생하는 것입니다 다시 시작한 후 마스크 : 내 응용 프로그램을 열

1) 정기적 인 작업을 수행합니다. 2) 내 응용 프로그램을 닫습니다 (조각 및 활동 삭제). 3) 응용 프로그램 서랍에서 내 응용 프로그램을 다시 엽니 다.

나는 라이프 사이클 이벤트에서 내가하고있는 일이라고 느낍니다. 그 중 누구와 마주 친 적이 있습니까? 뭐가 문제 야? 활동의

Answer 1

fm = getFragmentManager(); 
FragmentTransaction ft = fm.beginTransaction(); 

ft.add(R.id.frameContainer, main, "main"); 
ft.setCustomAnimations(R.animator.fade_in, android.R.animator.fade_out); 
ft.add(R.id.mediaControllerFrame, mdc); 
ft.commit(); 
getFragmentManager().executePendingTransactions(); 

첫 번째에서 단편 초기화 만 수행해야합니다 (onCreate()). 은 구성 변경 사항을 통해 조각을 유지하므로, 화면을 회전하려면 onCreate()이 다시 호출되며 매번 이전 인스턴스 위에 다른 인스턴스 인 main 및 mdc이 추가됩니다.

대신 조각 초기화 코드를 savedInstanceState이라는 null 체크로 감싸십시오.

if (savedInstanceState == null) { 
    fm = getFragmentManager(); 
    FragmentTransaction ft = fm.beginTransaction(); 

    ft.add(R.id.frameContainer, main, "main"); 
    ft.setCustomAnimations(R.animator.fade_in, android.R.animator.fade_out); 
    ft.add(R.id.mediaControllerFrame, mdc); 
    ft.commit(); 
    getFragmentManager().executePendingTransactions(); 
}
