android 使用 recyclerview 渲染服务端图片列表不显示？-灵析社区

`Recyclerview` 的 `layout` 布局文件如下： 适配器代码如下： public class ImageRecyclerViewAdapter extends RecyclerView.Adapter { private final Activity activity; private final List images; public ImageRecyclerViewAdapter(Activity activity, List images) { this.activity = activity; this.images = images; } @NonNull @NotNull @Override public ImageViewHolder onCreateViewHolder(@NonNull @NotNull ViewGroup parent, int viewType) { LayoutInflater inflater = LayoutInflater.from(parent.getContext()); // 注意第三个参数；仅返回视图，不附加视图到parent View view = inflater.inflate(R.layout.recyclerview_item_image, parent, false); return new ImageViewHolder(view); } @Override public void onBindViewHolder(@NonNull @NotNull ImageViewHolder holder, int position) { String src = this.images.get(position); ImageView imageView = holder.getImageView(); // 填充src Glide.with(this.activity.getBaseContext()) .load(src) .into(imageView); } @Override public int getItemCount() { return this.images.size(); } } 通过上述代码渲染视图图片不显示！如果给图片布局设置一个高度又可以正常显示，这是为什么？
