加载专辑封面的代码

    if(cursor != null && cursor.moveToFirst()){

        int titleColumn = cursor.getColumnIndex(MediaStore.Audio.Media.TITLE);
        int idColumn = cursor.getColumnIndex(MediaStore.Audio.Media._ID);
        int artistColumn = cursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);
        int albumColumn = cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM);
        long albumID = cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ID);

        do {
            long thisID = cursor.getLong(idColumn);

            String thisTitle = cursor.getString(titleColumn);
            String thisArtist = cursor.getString(artistColumn);
            String thisAlbum = cursor.getString(albumColumn);

            Glide.with(this)
                    .load(albumID)
                    .asBitmap()
                    .into() //How do I return a value?

            medialist.add(new SongInfo(thisID, thisTitle, thisArtist, thisAlbum, //Bitmap variable));
        }
        while (cursor.moveToNext());

我正在尝试使用Glide将专辑封面加载到列表视图中。但是，我遇到了麻烦;

medialist.add（新的SongInfo（..）;

Answer 1

你做错了：用这个：

medialist.add(new SongInfo(thisID, thisTitle, thisArtist, thisAlbum,albumID));

现在，在listview适配器类中，获取medialist并使用glide方法：定义：

Context con;

现在在适配器的构造函数中：

public CustomAdapter(List<Medialist> items, Context context) {
        medialist= items;
        this.con = context;
    }

Glide.with(con)
                    .load(medialist.getAlbumID)
                    .asBitmap()
                    .into(imageview)

使用Listview将专辑封面加载到Glide中
