메신저 완전히 새로운 자바와 안드로이드 dev에 그래서 잘하면 내가 뭘하려고 노력하고 설명 할 수 있습니다 (따라서 나는 내 코드에 너무 많은 의견을 가지고 시도하고 도움이 될 수 있습니다. 나와 함께).최종 변수가 아니거나 전역 변수입니까? 나는 1을 추가하고 다시 루프를 추가하고 싶지만 어떻게
ibnext 버튼을 클릭하면 그림 (및 연관된 txt 파일)이 다음 그림으로 변경되기를 원하기 때문에 자산 폴더에 그림 집합이 있습니다. 간단하게 유지하려면 txt 파일과 사진 이름 1.TXT & 1.JPG, 2.txt 있습니다 & 2.JPG 등
다음은 내 코드와 첫 번째 이미지 및 TXT를 표시하기위한 모든 작동하지만 "progressL1"에 1을 더한 다음 이미지와 txt를 다시 그릴 수는 없습니다. 나는 나에게 많은 의미를 가지지 않는 최종 변수와 전역 변수를 검색하는 루프에 갇혀있다.
도움말을 잘하십시오, 미안 그 같은 초보자 질문을하지만,이와 손실에 임 ...받은

내가 원하는 것에 더 가깝다고 생각하지만, progressL1이 ++ 이후 public loadDataFromAsset 섹션을 호출하는 방법을 아직도 모른다.
이 코드가 더 좋다고 생각하십니까? 누구를 생각해?
