滑动不从网址加载图片

Question

我有一个问题我是使用Glide从网址加载图片但是如果徽标网址为空则我需要进行验证，然后使用另一个网址来获取图片，但它不起作用我不知道为什么

     @Override
        public void onBindViewHolder(SearchHorizontalAdapter.ViewHolder holder, int position) {

            holder.mTitle.setText(premiumsList.get(position).getName());

            if(premiumsList.get(position).getLogo_url_string()==null){
           Glide.with(this.activity).load(premiumsList.get(position).getUrl()).into(holder.mImg);
                Log.d("",String.valueOf(premiumsList.get(position).getUrl()));
            }
else{
            Glide.with(this.activity).load(premiumsList.get(position).getLogo_url_string()).into(holder.mImg);
    }
        }

Answer 1

你关心小事：

1. 根据活动/片段
传递正确的上下文
2. 使用.placeholder
3. 使用.error轻松识别问题

编辑：请尝试此操作并尽可能提供堆栈跟踪

@Override
public void onBindViewHolder(SearchHorizontalAdapter.ViewHolder holder, int position) {

    holder.mTitle.setText(premiumsList.get(position).getName());

    if(premiumsList.get(position).getUrl()!=null){

        Glide.with(this.activity).load(premiumsList.get(position).getUrl())
            .listener(new RequestListener<String, GlideDrawable>() {
            @Override
            public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
                Log.e("IMAGE_EXCEPTION", "Exception " + e.toString());
                return false;
            }

            @Override
            public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
                Log.d("Sometimes the image is not loaded and this text is not displayed");
                return false;
            }
        })
        .into(holder.mImg);
    }
    else{      
        Glide.with(this.activity).load(premiumsList.get(position).getLogo_url_string()).into(holder.mImg);
    }
}
