[Android] 피아노 어플만들기  (0) 2018.08.17
[Android] Open API 사용해서 부산 버스 어플 만들기  (5) 2018.08.17
반응형

미니 플젝으로 피아노 만들어보았다.



HorizontalScrollview에 FrameLayout을 얹고 white keyboard, black keyboard를 배치하였다.


피아노 키에 대해서 잘 모르는 관계로... 저 첫시작 도가 c1인지 c2인지.. 잘 모르겠다..


피아노 음은 일일이 음을 따올수가 없어서 어플 다운받아서 디컴파일하여 음을 가져왔다.


https://apkpure.com/ << 컴퓨터에서 apk파일 다운로드 하는 사이트


디컴파일 하는 방법을 이것 저것 다 시도해보다가


https://www.youtube.com/watch?v=VLsJETb3m4M << 유튜브의 이 영상을 보고 많은 도움을 얻었다.


http://www.javadecompilers.com/ << 영상에서 소개해주는 디컴파일 사이트


(참고로..

평소 음원 확장자를 .mp4나 wav파일만 알고 있어서 이걸로 찾으려니 안찾아졌다..

디컴파일하여 얻은 음원의 확장자는 ogg였다.

ogg란?

------------------------------------------------------------------------------------------------------------------------------------------------

Ogg(오그)는 멀티미디어 컨테이너 포맷이다. 특허권으로 보호되지 않는 오픈 표준 파일 형식으로 멀티미디어 비트스트림을 효율적으로 전송하고 처리할 수 있게 하기 위해 Xiph.Org 재단에서 개발한 것이다.

------------------------------------------------------------------------------------------------------------------------------------------------

지식 하나 더 얻어간다@_@)


프로젝트 폴더\res폴더에 디컴파일하여 얻은 음원을 raw폴더를 생성하여 여기에 넣어준다.


레이아웃 가로모드 설정하기 위해서 프로젝트 폴더 경로를 따라 res 폴더로 들어가서 한개로 되어있는 layout폴더를



이렇게 두개로 나눠준다.(각각 폴더 안에 xml파일 포함되어 있음.)


결과적으로 안드로이드 스튜디오 가서 폴더를 확인해보면 layout폴더 밑에 actibvity_main(2)라고 설정 되어있는것을 볼 수 있다.




다음은 piano xml, java코드이다.


< activity_main.xml> 

버튼이 많은 관계로 엄청 길다...

[Android] Open API 사용해서 부산 버스 어플 만들기  (5) 2018.08.17
반응형

미니 플젝으로 평소에 만들어보고 싶었던 '부산 버스' 어플을 구현하였다.


API는 공공데이터 포털(data.go.kr)에서 받아왔으며 xml로 파싱하여 값을 받아왔다.


api 파싱과 값 뽑아오는 부분에서는 정말 맨땅에 헤딩이어서 이틀 밤샘 삽질하다가 겨우겨우 해결했다ㅠㅠ


http://movie13.tistory.com/1 << 여기 이 블로그에서 많은 도움을 받았다!!


위의 사이트에서 원하는 api를 검색 후 활용신청하고 end point 와 service key를 받아놓는다. 참고문서도 내려받아서 참고하면된다.


UI부분에 좀 더 투자를 하고 싶었지만 값을 받아내는데 급급해서 사진만 넣고 스크롤뷰에 textview만 넣었다..


<레이아웃>



버스번호와 정류장 번호를 입력하면 해당 정류장에 입력한 버스가 언제 도착하는지를 알려준다.



근데.. 제작 다하고 발표하는 날에 치명적인 오류가 발생하였다..



????? 현재시각 오전 11:13 인데 절대 버스가 없을리가 없는데 왜이렇지 하고 코드분석을 했는데...


알고보니


띠용 ...... 이럴수가....


이 상태가 된지 2주가 넘은거같은데 처리 부탁드립니다...(_ _)


아래는 안드로이드에서 작업한 xml과 java코드이다.
