imgview.setImageResource(R.drawable.img);
이런식으로 해서 imgview의 그림을 바꾸려고 합니다.
그런데 바뀌질 않습니다.
에러같은게 뜨질 않는걸로 보아, invalidate같은게 있어야 적용될 것 같다고 추측만 해볼 뿐입니다.
혹시 수정된 layout의 내용을 다시 불러오는 그런 함수같은게 없을까요?




아래는 해결 되었습니다.

        Intent intent = new Intent(this, Information9.class);
        startActivity(intent);
그냥 액티비티 전환이 안됩니다...
Information9 클래스가 담긴 자바파일도 있고 매니페스트에도 다른 것들과 똑같이 넣었는데
이것만 런타임이 뜹니다...


올린김에 한가지 더 여쭈어보자면
xml 파일 내의 TextView 말인데요
이거 정해진 width값보다 글자 수가 길면 자동으로 다음줄로 넘어 가도록 하는 옵션 없습니까?
찾기가 참 힘듭니다.

   

부탁드립니다.
