Java代码

@Override
    public void onBindViewHolder(VideosViewHolder holder, int position) {
        Video video = mList.get(position);
        holder.mTitle.setText(video.getTitle());
        holder.mPublishTime.setText(video.getPublishAt());
        Glide.with(context).load(video.getThumbnail()).into(holder.mThumbnail)
  }

Answer 1

您可以使用以下代码：Picasso.get（）。load（url）.placeholder（R.drawable.user_placeholder）// set Default Image .error（R.drawable.user_placeholder_error）// set default image .into（imageView）;
