Question

我一直试图将位图设置为MP3的封面艺术，但我似乎无法使其正常工作。它没有抛出任何错误，但是当我播放MP3时，位图没有显示。

这就是我目前所拥有的：

TagLib.File f = TagLib.File.Create("song.mp3");

Image currentImage = getAlbumArt(result.passedAlbumID);
Picture pic = new Picture();
pic.Type = PictureType.FrontCover;
pic.MimeType = System.Net.Mime.MediaTypeNames.Image.Jpeg;
pic.Description = "Cover";
MemoryStream ms = new MemoryStream();
currentImage.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
ms.Position = 0;
pic.Data = ByteVector.FromStream(ms);
f.Tag.Pictures = new IPicture[1] { pic };
pictureBox1.Image = currentImage; //testing the image is correct

f.Save();
ms.Close();

我正在使用以下代码，一切正常对我来说：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode){
        case OUR_REQUEST_CODE:
            if(resultCode == RESULT_OK) {
                //Do something useful with data
            }
            break;
    }
}

根据您提供的代码，我唯一注意到的是，我的代码使用了以下行

TagLib.File file = TagLib.File.Create(/*path to your mp3 file*/);
TagLib.Picture pic = new TagLib.Picture();
pic.Type = TagLib.PictureType.FrontCover;
pic.Description = "Cover";
pic.MimeType = System.Net.Mime.MediaTypeNames.Image.Jpeg;
MemoryStream ms = new MemoryStream();
/*your image*/.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
ms.Position = 0;
pic.Data = TagLib.ByteVector.FromStream(ms);
file.Tag.Pictures = new TagLib.IPicture[] { pic };
file.Save();
ms.Close();

而不是

file.Tag.Pictures = new TagLib.IPicture[] { pic };

如果你删除方括号内的f.Tag.Pictures = new TagLib.IPicture[1] { pic };，只需尝试一下。
