Glide not reload the images from server - android-glide

Question

I have a recyclerview that displays photos.
this is my adapter:
public class CustomerImageListAdapter extends RecyclerView.Adapter<CustomerImageListAdapter.Holder> {
private Context context;
private List<String> imageUrls;
public CustomerImageListAdapter(Context context, List<String> imageUrls) {
this.context = context;
this.imageUrls = imageUrls;
}
#NonNull
#Override
public Holder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View rootview = LayoutInflater.from(context).inflate(R.layout.customer_onitemclick_image_viewpager_item, parent, false);
return new Holder(rootview);
}
#Override
public void onBindViewHolder(#NonNull Holder holder, int position) {
Glide.with(context).load(imageUrls.get(position)).into(holder.imageView);
if (imageUrls.size() != 0) {
for (int i = 0; i < imageUrls.size(); i++) {
Log.i("urls", "onBindViewHolder: " + imageUrls.get(i));
}
}
}
#Override
public int getItemCount() {
return imageUrls.size();
}
class Holder extends RecyclerView.ViewHolder {
ImageView imageView;
public Holder(#NonNull View itemView) {
super(itemView);
imageView = itemView.findViewById(R.id.customer_onitemclick_image_viewpager_item_imageview);
}
}
public void setImageUrls(List<String> imageUrls1) {
imageUrls.addAll(imageUrls1);
notifyDataSetChanged();
}
}
when i set the "imageurls" in the constructor, recyclerview show the images perfectly;
imageListAdapter = new CustomerImageListAdapter(getContext(),urls);
but when i set in constructor "new ArrayList()" and use "setImagesUrls" method to update "imageurls",
then recyclerview don't show images .
imageListAdapter = new CustomerImageListAdapter(getContext(),new ArrayList<String>());
...
...
...
#Override{
public void onChanged(List<String> strings)
imageListAdapter.setImageUrls(strings);
}
While based on the "log" ,address of the images are received from the server.
#Override
public void onBindViewHolder(#NonNull Holder holder, int position)
{
Glide.with(context).load(imageUrls.get(position)).into(holder.imageView);
if (imageUrls.size() != 0) {
for (int i = 0; i < imageUrls.size(); i++) {
Log.i("urls", "onBindViewHolder: " + imageUrls.get(i));
}
}
}
thanks for your help
