안드로이드, 간단 투표 앱 결과 화면 출력

안드로이드, 스튜디오, 투표, 어플리케이션, 앱

결과화면까지 출력되게 하기

과제일시 : 2020-03-31

지난 주 과제 당시했었던 투표 어플은 기능으로따지만 절반정도만 완성된 상태였습니다.

[DEVELOPMENT/모바일앱개발] - 안드로이드, 간단한 투표 앱 만들기

안드로이드, 간단한 투표 앱 만들기

이번엔 이 투표하는 어플의 생명을 불어넣는 결과 화면 출력을 하려고 합니다.

저번 주 했던 것은 위 게시글을 확인하고 오시면 됩니다 :D 

먼저, 소스 코드를 보여드리겠습니다.

 오늘은 소스 코드가 생각보다 길게 느껴지지만 쉽게 생각하고 이해하면 화면을 한게 더 만들어 한쪽화면은 투표 화면을 만들고 투표 종료를 누르게 되면, 결과를 출력하는 화면을 하나 더 생성을 했습니다.

*.java에는 기능을 넣는다고 생각하면 편할 것 같고, *.xml에는 화면을 구성한다고 생각하면 편할듯합니다.

 

실행화면

아직은 많이 알아가야하는 단계라고 생각합니다. 좀 더 노력하고 열심히 하겠습니다.
