나는 SD 카드에 음악에서 앨범 아트를 얻기에 문제가public void onBindViewHolder(SongHolder holder, final int position) {
//holder.tvIndex.setText(String.format(Locale.US, "%d", position));
holder.tvSongTitle.setText(songList.get(position).getTitle());
holder.tvArtistName.setText(songList.get(position).getArtist());

, 앨범을 얻을 수있는 가장 쉬운 방법은 무엇입니까 예술, 그리고 그것을 imageview에 표시? 내가 잘못하고있는 것에 대한 단서가 없다.이 포럼의 다른 게시물을 살펴 보았지만 아무 소용이 없지만 올바르게 수행하는 방법을 찾지 못했습니다.
감사합니다,

'MediaSto re.Audio.Albums.EXTERNAL_CONTENT_URI'는 이미 예술이있는 URI입니다. 왜 Uri.parse ("file : //"'? –
songList.get (position) .getAlbumart() 만 필요합니까? – Vince
그 값이 무엇인지는 분명하지 않습니다. URI가 아닌 문자열입니다. https://stackoverflow.com/a/23681332/2308683 –
