@Override
public ItemCategoryViewAdapter.ViewHolder onCreateItemViewHolder(ViewGroup parent, int itemType) {
    View view = LayoutInflater.from(context).inflate(R.layout.indiv_stall_detail_category, parent, false);
    return new ItemCategoryViewAdapter.ViewHolder(view);
}

@Override
public HeaderViewHolder onCreateHeaderViewHolder(ViewGroup parent, int headerType) {
    View v = LayoutInflater.from(context).inflate(R.layout.cart_header, parent, false);
    return new HeaderViewHolder(v);
}

Code reference for the above error.

Thanks in advance

I had the same error after updating support libraries to version 27.1.0

[Dona278]

@elitelokesh seems to be caused by onCreateGhostHeaderViewHolder in SectioningAdapter.java and related to this pull request.

The parent.addView() method used here attach the view to the parent, so the problem aren't onCreateItemViewHolder or onCreateHeaderViewHolder custom implementation.

I found this workaround: override onCreateGhostHeaderViewHolder method into custom adapter like the others

@Override
public GhostHeaderViewHolder onCreateGhostHeaderViewHolder(ViewGroup parent) {
    final View ghostView = new View(parent.getContext());
    ghostView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));

    return new GhostHeaderViewHolder(ghostView);
}

@Dona278 your answer really help me Thanks. My problem is also 27.1.0 not working on that .

[KennyGoers]

Is there a release pending?

[milanPansuriya]

I am facing the same issue is there any update on this issue?

[CeccoCQ]

Same issue.

[milanPansuriya]

I had found the solution for this plz update your code `public GhostHeaderViewHolder onCreateGhostHeaderViewHolder(ViewGroup parent) { LayoutInflater inflater = LayoutInflater.from(parent.getContext());

View v = inflater.inflate(R.layout.ghost_view, parent, false); return new GhostHeaderViewHolder(v); }`

Please add an empty layout to onCreateGhostHeaderViewHolder

[WeiLianYang]

@Dona278 Thanks very much! I've solved the problem.

[kshipraShelke]

same error

[rion18]

I tried @Dona278's solution but now my recyclerview is completely empty. Any ideas? Debugging execution, I noticed that after onCreateGhostHeaderViewHolder, no onCreateItemViewHolder is being called. I have a NestedScrollView, and inside is the RecyclerView.

[Vishal99784]

@Dona278 Thanks very much! I've solved the problem.

[Arxing]

@Dona278 Thanks!!! I solved the problem.

[Divala]

@Dona278 thanks!!

[sacdulanga]

@Dona278 Thank you!

[chandmohd]

@Dona278 hey Thank you , I have migrated my project into AndoridX so had a problem so i tried your solution and it perfectly worked !

[Dona278]

After a year seeing that my workaround still helps makes me happy! 🎉

[TothSteven]

@Dona278 Thank you! You saved the day for me :)

[MuruganSKutty]

I tried @Dona278 solution now above issue cleared but recyclerview is empty(showing nothing). I'm using 'com.android.support:appcompat-v7:27.1.1' & 'org.zakariya.stickyheaders:stickyheaders:0.7.6'. Please update if any solution.

[TothSteven]

Hi @MuruganSKutty I also use 'com.android.support:appcompat-v7:27.1.1' and 'org.zakariya.stickyheaders:stickyheaders:0.7.6' and for me works perfectly

[MuruganSKutty]

I found another cause of invisible recyclerview, i.e (Recylerview is present inside the NestedScrollView). Please any help @Dona278 , @TothSteven .

[TothSteven]

Hi @MuruganSKutty I'm using it in a tabLayout with fragments and initialize the sectioningAdapter in the Fragments onCreate and poputale the items in the Fragments onResume, have not tested it with NestedScrollView

[ShamylZakariya]

Hey I want to apologize to everybody. My job has been very demanding, and I've had to ignore all this. I've fixed the bug, and am upgrading to androidx, newer gradle etc. I will push a release in the next few days.

[Crasheng]

@Dona278 hey Thank you , I have migrated my project into AndoridX so had a problem so i tried your solution and it perfectly worked !

@Dona278 @chandmohd i have updated to AndroidX and in my customer Adapter the one extending the SectionAdapter i have override the same method and it still gives me the same problem
