  //custom adapter is here
public class CustomVideoListViewAdapter extends ArrayAdapter<AudioModel> {
Context vcontext;
public CustomVideoListViewAdapter(Context context, int resourceId,
                             List<AudioModel> items) {
    super(context, resourceId, items);
    this.vcontext= context;
}
private class VideoViewHolder {
    ImageView imageView;
    TextView txtTitle;
    TextView txtDesc;
}
public View getView(int position, View convertView, ViewGroup parent) {
    CustomVideoListViewAdapter.VideoViewHolder holder = null;
    AudioModel rowItem = getItem(position);
    String path=rowItem.getaPath();
    Bitmap thumb = ThumbnailUtils.createVideoThumbnail(path,
            MediaStore.Images.Thumbnails.MINI_KIND);

    LayoutInflater mInflater = (LayoutInflater) vcontext
            .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.video_list, null);
        holder = new CustomVideoListViewAdapter.VideoViewHolder();
        holder.txtTitle = (TextView) convertView.findViewById(R.id.video_file_nameView);
        holder.imageView = (ImageView) convertView.findViewById(R.id.videothumbnail_view);
        convertView.setTag(holder);
    } else
        holder = (CustomVideoListViewAdapter.VideoViewHolder) convertView.getTag();
    holder.txtTitle.setText(rowItem.getaName());
    holder.imageView.setImageBitmap(thumb);

    return convertView;
}

运行此应用程序代码时，我无法获取视频文件列表的缩略图，但视频未显示但声音正在播放。
我已经设置了两个不同的自定义适配器来显示视频列表和音频列表...我在这里遇到的问题是视频列表未按预期从视频列表布局中显示...

listview与自定义适配器不显示缩略图...而是显示不同的图片
