使用Glide库时ImageView无法显示图片URL的问题求助

之前能正常获取图片URL并显示在RecyclerView项的ImageView里，修改后失效，无法定位问题原因。

逻辑代码 #

if (currentMsg.type == "photo"){            
    viewHolder.binding.sentImgL.visibility = View.VISIBLE
    viewHolder.binding.sentTxtMsgL.visibility = View.GONE
    //holder.binding.sentImg.setImageURI(currentMsg.urlImg?.toUri())
    Glide.with(holder.itemView.context).load(currentMsg.message).into(holder.binding.sentImg)
}

排查建议 #

• 确认currentMsg.message的有效性：打印该字段值，检查是否为空、缺少http/https前缀，或者是无效的图片链接。
• 检查Glide依赖：确认build.gradle中Glide的依赖配置未被误删，无版本冲突。
• 验证ImageView布局：确认sentImg未被父布局遮挡，且自身visibility属性正常。
• 添加Glide错误监听，获取加载失败详情：

Glide.with(holder.itemView.context)
     .load(currentMsg.message)
     .listener(new RequestListener<Drawable>() {
         @Override
         public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
             e.printStackTrace();
             return false;
         }

         @Override
         public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
             return false;
         }
     })
     .into(holder.binding.sentImg);

• 检查网络权限：若加载网络图片，确保AndroidManifest.xml中已添加<uses-permission android:name="android.permission.INTERNET"/>。
• 排查混淆问题：若开启代码混淆，确认proguard规则中已包含Glide的相关配置。
