please take a look on new StickyHeaderGridLayoutManager(SPAN_SIZE);

Not working in dialog.

Hi. My adapter good working anywhere but not working in dialog. RecyclerView is "empty" (but I see little gray line). itemsCount > 0

val dialog = MaterialDialog.Builder(activity)
                .customView(R.layout.paid_sites_dialog, false)
                .positiveText(R.string.done)
                .negativeText(R.string.cancel)
                .build()

        val freeSitesTrigger = dialog.findViewById(R.id.freeSitesTrigger) as FreePaidTriggerButton
        val sitesRecyclerView = dialog.findViewById(R.id.sitesRecycler) as RecyclerView
        sitesRecyclerView.layoutManager = StickyHeaderGridLayoutManager(3)
        sitesRecyclerView.adapter = FilterPaidSitesAdapter()
        dialog.show()

Sluggish behavior in the scroll for large dataset

Video: https://imgur.com/a/aF5b3nB
Tested sample app with the following data:

private static final int SPAN_SIZE = 3;
private static final int SECTIONS = 50;
private static final int SECTION_ITEMS = 200;

Expand / Collapse sections?

Is it possible to expand and collapse sections dynamically? I'd like to add click listeners to the headers that hide/show the items in it, but can't find a solution at the moment. Let me know if you need any more info. thanks!!

getSectionHeaderPosition not working when isSectionHeaderSticky return false

SwipeRefreshLayout - the RecyclerView is not pulled down

I have a RecyclerView with StickyHeaderGridLayoutManager and when using SwipeRefreshLayout the RecyclerView is not pulled down

Update SDK & Support Libs

Pleas Update to current SKD Version (27)

Removing last item from group does not remove header.

So I have a group with sub-items. When I remove the items it works fine with

notifySectionItemRemoved(section, item)

This removes the item, but if it's the last item, the header remains.
I have tried

notifySectionHeaderChanged(section);

and I have even tried using the initial RecyclerView adapter's

if (mGroupedList.get(section).postList.size() == 0) { notifyItemRemoved(section);}

Still no luck. Is there anything else I need to do to remove it?

ScrollBar not work fine

Updating data using notifySectionDataSetChanged while multithreading

In calculateSections method, the getSectionCount is called twice: the first time to populate mSections list and the second time to calculate mSectionIndices. This is working fine in case the whole work is done in one thread.

In my case, I had a big number of data to work on and I used several threads to do so and after finishing working on a section, I call the if the notifySectionDataSetChanged to be executed on the UI thread.

In some cases, if the work on the other threads is being processed faster than the UI thread, the values returned by getSectionCount between the first call and the second one, are different:

I/Sticky: section count before : 4
I/Sticky: section : StickyHeaderGridAdapter$Section@25ef8b0d
I/Sticky: section : StickyHeaderGridAdapter$Section@3c6a5ac2
I/Sticky: section : StickyHeaderGridAdapter$Section@14fbf0d3
I/Sticky: section : StickyHeaderGridAdapter$Section@8d80410
E/Sticky: section count after : 5

I fixed this by calling the getSectionCount only once.

Recyclerview and Viewpager as an Item of Sticky Header

Hi,

I have a performance issue especially API 19-20-21. I have a Viewpager and four horizontal recyclerview's which has different views inside my main recyclerview which has a adapter that extends StickyHeaderGridAdapter. While scrolling up and down if screen contains the sub recyclerviews or viewpager, frame drops.

Here is my implementation for recyclerviews. Is there any way to improves its performance. Because of the recyclers' views are different I can't use the same viewpool for them.

`final ViewHolderLowerRecyclerSlider lowerSlider = (ViewHolderLowerRecyclerSlider) viewHolder;
final LinearLayoutManager lowerSliderMan = new LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false);
lowerSlider.rvMainPageSlider.post(new Runnable() {
@OverRide
public void run() {
LowerCuffAdapter upperCuffAdapter = new LowerCuffAdapter(context, mData.get(section).getItems(), new MainPageAdapterClick() {
@OverRide
public void onItemClick(NewsItemsModel newsItem) {
clickListener.onItemClick(newsItem);
}
});
lowerSlider.rvMainPageSlider.setLayoutManager(lowerSliderMan);
lowerSlider.rvMainPageSlider.addItemDecoration(new CustomItemDecorationHorizontal(5, 10, 5, 10));
lowerSlider.rvMainPageSlider.setAdapter(upperCuffAdapter);
}
});

        lowerSlider.rvFinance.post(new Runnable() {
            @Override
            public void run() {
                FinanceAdapter financeAdapter = new FinanceAdapter(context, financeList);
                LinearLayoutManager financeLayManager = new LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false);
                lowerSlider.rvFinance.setLayoutManager(financeLayManager);
                lowerSlider.rvFinance.setAdapter(financeAdapter);
            }
        });

        lowerSlider.rvWeather.post(new Runnable() {
            @Override
            public void run() {
                LinearLayoutManager weatherLayManager = new LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false);
                WeatherAdapter weatherAdapter = new WeatherAdapter(context,list);

                lowerSlider.rvWeather.setLayoutManager(weatherLayManager);
                lowerSlider.rvWeather.setAdapter(weatherAdapter);
            }
        });`

PagedList support.

I'm trying (and failing) to get this working with a PagedList for convenient paging of large datasets. Is this something you plan on introducing in the future?

How to disable headers?

I'm testing the library. I appreciate your work.

My question is, what's the best way for actually disabling the headers functionality?

The point is that I don't always need them on the RecyclerView I'm using, so I'd like to be able to switch it off conditionally.

Is the recommended way to simply return empty / invisible Views from onCreateHeaderViewHolder? This seems to do the trick, but I wonder if there was perhaps some more elegant way of accomplishing this.

Support for RTL languages

In RTL languages, the first item in a grid list would be in the top right. Currently, with StickyHeaderGridLayoutManager it's always in the top left.

The standard GridLayoutManager allows you to specify RTL layout, for RTL language support. It'd be great if StickyHeaderGridLayoutManager allowed you to do the same.

clicking an item affects another item

Hi,

There's nothing wrong with the grid but when I click an item - say section 0, item 10 - the onClick action is triggered on section 0, item 0! I log the section and position and they're always correct. here's the onBindItemViewHolder method:

`public void onBindItemViewHolder(ItemViewHolder viewHolder, final int section, final int position) {
final SubjectViewHolder holder = (SubjectViewHolder) viewHolder;
Subject subject = subjects.get(section).get(position);

    holder.tvName.setText(subject.getNameEn());


    Glide.with(context)
            .load(subject.isSelected() ? R.drawable.ic_star_selected : R.drawable.ic_star)
            .into(holder.ivSelection);


    holder.tvName.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.e("CLICK", "SEC: " + section + " POS: " + position);
            Flubber.with()
            .animation(Flubber.AnimationPreset.POP)
            .duration(600)
            .createFor(holder.tvName)
            .start();
        }
    });`

How can I fix this?

How to scroll to desired header position?

Hey,

Horizontal Scrolling

Does this support horizontal scrolling? Thank you and God bless.
