我需要将基于URL的视频缩略图显示到ImageView我的ListView项目的视图子项中,我找到了这个帖子但没有工作.

结果

码

        thumb_image.setImageBitmap(new LoadVideoThumbnail().execute(URLs.videos +"/"+videos.get(position).getId()+".mp4").get());

的AsyncTask

public class LoadVideoThumbnail extends AsyncTask<String, Object, Bitmap>{

        @Override
        protected Bitmap doInBackground(String... objectURL) {
            //return ThumbnailUtils.createVideoThumbnail(objectURL[0], Thumbnails.MINI_KIND);
            return ThumbnailUtils.extractThumbnail(ThumbnailUtils.createVideoThumbnail(objectURL[0], Thumbnails.MINI_KIND), 100, 100);
        }

        @Override
        protected void onPostExecute(Bitmap result){
             //img.setImageBitmap(result);
        }

    }
