So after a long time, I've finally found a way to display an Horizontal RecyclerView into another RecyclerView.
I followed this tutorial: http://mithunkumarc.blogspot.com/2016/09/nested-recyclerview-or-inner-recycler.html
To put some context, I am fetching some JSON data, into an object called "Application". I have three different fragments. These fragments are displaying RecyclerView with the previous data.
Into these applications, I have for each one a list of photos. So I followed the mentionned tutorial to display these photos into another RecyclerView (Sounds a lot like Nested RecyclerView)
But when I launch my first fragment, I encounter the following error:

Child Adapter (also onCreateViewHolder & onBindViewHolder)
@NonNull
@Override
public PhotoAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View mPhotoItem = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_application_photo, parent, false);
return new ViewHolder(mPhotoItem);
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
final Application mApplication = mListOfApplications.get(position);
if (mApplication != null) {
if (!mApplication.getmListOfViews().isEmpty()) {
for (int i = 0; i < mApplication.getmListOfViews().size(); i++) {
String mPath = mApplication.getmListOfViews().get(i)
.replaceAll("\\[", "")
.replaceAll("\"", "")
.replaceAll("\\]", "");
mApplication.getmListOfViews().set(i, mPath);
}
for (int j = 0; j < mApplication.getmListOfViews().size(); j++) {
ImageView mImageView = holder.mPhotoIV;
int width = mImageView.getLayoutParams().width;
int height = mImageView.getLayoutParams().height;
Picasso.get()
.load(mApplication.getmListOfViews().get(j)).resize(width, height)
.error(R.drawable.ic_no_photo_foreground).into(mImageView, new com.squareup.picasso.Callback() {
@Override
public void onSuccess() {
}
@Override
public void onError(Exception e) {
}
});
}
}
}
}
EDIT: Method getItemCount from PhotoAdapter
@Override
public int getItemCount() {
return mListOfPhotos.size();
}
I have debugged my application, mListOfApplications and mListOfPhotos have the right and expected data.
What am I missing :)?
