                    Intent currSong = new Intent(DisplaySongsActivity.this, SongActivity.class);

    String selection = MediaStore.Audio.Media.IS_MUSIC + "!=0";
    Cursor myCursor = getContentResolver().query(songUri, null, selection, null, null);


    if (myCursor != null && myCursor.moveToFirst()) {
        int id_Column = myCursor.getColumnIndexOrThrow(MediaStore.Audio.Media._ID);

        do {

            Long songId = myCursor.getLong(id_Column);

            String songData = myCursor.getString(data_Column);
            String songName = myCursor.getString(title_Column);
            String songArtist = myCursor.getString(artist_Column);
            String songAlbum = myCursor.getString(album_Column);

            QuerySongs querySongs = new QuerySongs(songId, songData, songName, songArtist, songAlbum);
            songList.add(querySongs);

        } while (myCursor.moveToNext());
        myCursor.close();
    }
}

}

Song constructor class;

public QuerySongs(Long songId, String songData,  String songName, String songArtist, String songAlbum){
    this.id = songId;
    this.albumId = albumId;
    this.data = songData;
    this.title = songName;
    this.artist = songArtist;
    this.album = songAlbum;

}

public Long getId(){
    return id;
}

public Long getAlbumId(){
    return albumId;
}

public String getData(){
    return data;
}


public String getTitle() {
    return title;
}


public String getArtist() {
    return artist;
}

public String getAlbum(){
    return album;
}

So this are my 2 classes, and i want to display the album art of all songs in an imageView. i'm trying it with Picasso to load it to imagevie but doesn't work, i'm doing something wrong with the path i think, i don't know how to get the path of an album. How can i solve this? Thanks,

Answer 1

The problem with the code is on your path. You instantiated path = to the position which is a number. To get path it must be:

 String path = songsList.get(position).get(MediaStore.Audio.Albums.ALBUM_ART);

You could use Glide or Picasso to show your images.
