한나 던컨 :
나는 나의 대학 수업의 하나에 대한 안드로이드 응용 프로그램을위한 홈페이지를 구축하고있다. 내 그룹은 안드로이드 Studio를 사용하고 있습니다. 나는 것을 나는 레이아웃을 가지고하지만 난에 오신 것을 환영합니다라고하는 위 상단에있는이 무작위로 여분의 공간이있다.
나는 상단에 그 임의의 간격을 제거하고 그 아래로 내 개체의 나머지 부분을 밀어 어떻게 알아낼 수 없습니다 (보고서 목록 탐색 표시 줄 아래에 사라집니다)
여기 내 fragment_home.xml입니다

나는 다른 파일을 포함할지 모르지만 잘하면 문제는 그 네 개의 파일에 있습니다. 나는 그 간격을 제거하기 위해 많은 것들을 시도했습니다,하지만 난 그것을 제거하는 방법을 알아낼 수 없습니다.
사전에 감사합니다!
Mayokun :
당신의에서 activity_main.xml파일의 제거하려고 android:paddingTop="?attr/actionBarSize"어떤 액션 바가 없기 때문에 ConstraintLayout 라인을.
