i use the code below to populate a recycler view containing image views and it works perfectly

}
long animationDelay = PHOTO_ANIMATION_DELAY + viewHolder.getAdapterPosition() * 30;

public static class PhotoViewHolder extends RecyclerView.ViewHolder {

PhotoViewHolder(View view) {
super(view);
ButterKnife.bind(this, view);
}
void bindView(FeedItem feedItem){
this.feedItem = feedItem;
}
}
}
but when i use
#Override
public void onPhotoClick(View v,int position, List<FeedItem> feedItems) {
FeedItem item = feedItems.get(position);
String name = item.getName();
Toast.makeText(getContext(),name + "Is the name ", Toast.LENGTH_LONG).show();
}
i get an error showing that my adapterposition is -1 and i am not sure where the -1 comes from because even when i remove the global variable initialized to -1 i still get -1 as the adapter position
In your onCreateViewHolder method you're returning new instance of PhotoViewHolder instead of cellFeedViewHolder in which you have defined your clicks.

The above code is my class which extends RecyclerView. Do I have to add some animator to expand the items. If yes where and how ?
I develop a fragment using Horizontal RecyclerView in a Vertical RecyclerView (like Google Play Store).
When i notifyDataSetChanged from the parent RecyclerView, the child RecyclerView lose the position because the setAdapter is call in the onBindViewHolder I think. Also when i scroll to the 5th position in the first horizontal recyclerview if i scroll down and come back up i loose the 5th position.
I try to use RecyclerView.scrollToPosition() but that don't work.
So i think i have two solution :
a way (by a method or setting) to keep the position of my child recycler view. (BEST SOLUTION)
a way to set manually the recyclerview position to where it was before the refresh. (ELSE SOLUTION)

If someone has a solution for me
Thank you
Store x scroll offset in a SparseArray for position and restore when bind view holder.
public class ProfilesCardViewListAdapter extends RecyclerView.Adapter<ProfilesCardViewListAdapter.ItemRowHolder> {
private SparseIntArray sparseArray = new SparseIntArray();
#Override
public void onBindViewHolder(final ItemRowHolder holder, final int position) {
// Use srollBy for animate scrolling
holder.itemRecyclerView.srollBy(sparseArray.get(position, 0), 0);
// Or scrollTo for restore previous x offset
//holder.itemRecyclerView.srollTo(sparseArray.get(position, 0), 0);
holder.itemRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
sparseArray.put(position, dx);
}
}
}
}
I found a solution, i use the onTouchListener in the child recyclerView to set a scrollPosition (i don't use onScrollListener because this method is deprecated) i implement a getter to this field to get the scroll position from the parent RecyclerView and so at the end of the onBindViewHolder in the parent RecyclerView i call (child)RecyclerView.scrollToPosition(scrollPosition).
And that's make the job

How can handle with this situation -> I have a list of itens in a recyclerView and I want to choose one of those option: green, yellow or red face to get the value of object from list item I chose
So I thought something like bellow, but when I select one of those faces anything happens. I think that button click listener doesn't work. Please someone can drive me to a better suggestion that works, give me an example or could me tell what am I doing wrong?
