public void removeCells(int fromPosition, int toPosition) {
    for(int i = fromPosition; i <= toPosition; ++i) {
        SimpleCell cell = (SimpleCell)this.cells.get(i);
        this.cells.remove(cell);
        this.removeCellType(cell);
    }

    this.notifyItemRangeRemoved(fromPosition, toPosition - fromPosition + 1);
}

isin't this always going to crash (Outofrange Index exception) at the position ((toPos - fromPos / 2) + 1)? Because this,cells is mutating..

We should replace SimpleCell cell = (SimpleCell)this.cells.get(i); with SimpleCell cell = (SimpleCell)this.cells.get(fromPosition);

or simply delete reverse

  for(int i = toPosition; i >= fromPosition; i--) {
        SimpleCell cell = (SimpleCell)this.cells.get(i);
        this.cells.remove(cell);
        this.removeCellType(cell);
    }

It is possible to add sticky footer ?

Need to be able to hide the load more view when it comes to the error from the server.

Hi again. Thatnks for fixer. I have found another one thing. There's no way to disable autoloading.
I mean I have loaded all elements, but there's no way to disable loading progress.

Having a sticky header section will overlap the top few views while you scroll up and down. However, onClick and onSwipe motions are still detected from the cell while interacting with the section header v1.1.6

Hi again, I have found another problem: loading view doesn't work with grid layout.

Is there a way to "Pull-To-Refresh" in SimpleRecyclerView?

Thanks for awesome lib !
About the auto load more feature, is it possible to add the footer (loading progress bar, etc.) ?

See this branch - https://github.com/ersin-ertan/Recycler/tree/multiTypeCrash

I'm testing two different types, TextCell and TextCell2, each of which uses their own data model of Text and Text2, respectively.

Press ADD to add a new TextCell2 to the list - > crash

java.lang.ClassCastException: com.nullcognition.recycler.TextCell2$ViewHolder cannot be cast to com.nullcognition.recycler.TextCell$ViewHolder at com.nullcognition.recycler.TextCell.onBindViewHolder(TextCell.java:15)

Headers are not showing up on init, only after I scroll down and up they appear to be drawn.
If I have only one item, I can't scroll and I can't see the header at all.
Do you have any idea why would that happen?

Header items appear to be unable to use either percentage guidelines (if
using ConstraintLayout) or align-to-right (if using RelativeLayout). This is
unfortunate, because the data items themselves work perfectly with ConstraintLayout
percentage guidelines, useful for aligning data into columns. In our case
we want the subsection header row items to show labels for those columns,
but due to this issue the header row layout directives are ignored, causing
(severe) misalignment.

Even using ancient RelativeLayout is problematic as it also ignores directive
to align to parent right edge -- the workaround for now is to use RelativeLayout
and progressively lay items out left to right, but this puts us back in old-school
dpi level territory, which was eliminated when ConstraintLayout percentages
were introduced.

The image attached below demonstrates the same ConstraintLayout .xml (using percentage guidelines)
when used standalone vs. when added via SimpleRecylerView "SimpleSectionHeaderProvider"
(note that the data items themselves successfully use ConstraintLayout percentage
guidelines to arrange data in columns, but the header rows ignore those directives)

Not doing anything fancy, should be similar to the bundled demo app (in kotlin) e.g.

    private fun addRecyclerHeaders(inflater: LayoutInflater, simpleRecyclerView: SimpleRecyclerView, historyListType: HistoryListType) {
        val sh = object : SimpleSectionHeaderProvider<SKResultsUIList>() {
            override fun getSectionHeaderView(skResultsUIList: SKResultsUIList, i: Int): View {
                val view = inflater.inflate(R.layout.result_history_list_header_card_view, null, false)
                ...
                return view
            }
            override fun isSameSection(currItem: SKResultsUIList, nextItem: SKResultsUIList): Boolean {
                return currItem.simpleRVCategory === nextItem.simpleRVCategory
            }

            // Optional, whether the header is sticky, default false
            override fun isSticky(): Boolean {
                return true
            }
        }
        simpleRecyclerView.setSectionHeader(sh)
    }

I have added an onCellClickListener to the cells in my recyclerview, which is a list of podcasts. The selected podcast should start playing when the user taps a cell in the list, but the onCellClicked method is never called. I have also added an onCellLongClicked method, and this one works fine, but it is not my intended functionality for the app.

Here is the code where I bind the data and create the listeners:

    List<DataManager.Podcast> podcasts = DownloadData.podcastList;
    List<DataManager.PodcastCell> cells = new ArrayList<>();
    for (DataManager.Podcast podcast:podcasts) {
        DataManager.PodcastCell cell = new DataManager.PodcastCell(podcast);
        cell.setOnCellClickListener(new SimpleCell.OnCellClickListener<DataManager.Podcast>() {
            @Override
            public void onCellClicked(DataManager.Podcast item) {
                Log.d("test", "CLICK");
            }
        });
        cell.setOnCellLongClickListener(new SimpleCell.OnCellLongClickListener<DataManager.Podcast>() {
            @Override
            public void onCellLongClicked(DataManager.Podcast item) {
                Log.d("test", "LONGCLICK");
            }
        });
        cells.add(cell);
    }
    recyclerView.addCells(cells);

And here's the console output when I attempt both types of clicking:
08-23 11:48:55.811 8394-8394/com.gmail.lpizzanakin.myfirstvbgapp D/test: LONGCLICK
08-23 11:48:56.767 8394-8394/com.gmail.lpizzanakin.myfirstvbgapp D/test: LONGCLICK
08-23 11:48:57.579 8394-8394/com.gmail.lpizzanakin.myfirstvbgapp D/test: LONGCLICK
08-23 11:48:58.410 8394-8394/com.gmail.lpizzanakin.myfirstvbgapp D/test: LONGCLICK
08-23 11:49:02.141 8394-8394/com.gmail.lpizzanakin.myfirstvbgapp D/test: LONGCLICK
08-23 11:49:03.442 8394-8394/com.gmail.lpizzanakin.myfirstvbgapp D/test: LONGCLICK
08-23 11:49:04.155 8394-8394/com.gmail.lpizzanakin.myfirstvbgapp D/test: LONGCLICK
08-23 11:49:05.382 8394-8394/com.gmail.lpizzanakin.myfirstvbgapp D/test: LONGCLICK

I don't see any differences between my implementations of both listeners, so I don't think there should be anything wrong with my code.

Quite hard to reproduce, but I played with it a little, and it crashed. Here's the log:

An amazing library that makes work even smoother and faster.
One feature to be added if possible which is FastScroll ability!

after I set the section header, how can I remove it without clear all my recyclerview?

Next section header does not stick if previous section has 1 item. Video of the bug: https://drive.google.com/open?id=1guFkYZtu5yd_bT6OTB3TktbZD6OZhumq

Standard implementation with recyclerView.enableSwipeToDismiss(swipeToDismissCallback, LEFT, RIGHT); crashing after element is swiped.

I want to remove items from recyclerview with the sticky header, but no luck at all. I tried with clearing all ArrayList before loading but no luck. I tried with rView.removeAllCells(true);. It will remove items with sticky header, but I tried to add items again (in same activity) first sticky header gets doubled and empty spaces are adding to the recyclerview.

  protected abstract long getItemId();

When DownloadCell getItemId() return 0. the recycler cell method onBindViewHolder will never be called.

The log of my debug are as follow.
Why onBindViewHolder called, must call getItemId?
I must provide a valid id for cell?

E: getItemId: a(cell data)
E: getItemId: a(cell data)
E: onBindViewHolder: position=1; aa(cell data)
E: getItemId: b(cell data)
E: getItemId: b(cell data)
E: onBindViewHolder: position=2; b(cell data)
E: getItemId: c(cell data)
E: getItemId: c(cell data)
E: onBindViewHolder: position=3; c(cell data)

    private class DownloadCell extends SimpleCell<DownloadBean, DownloadViewHolder> {

        private DownloadCell(DownloadBean item) {
            super(item);
        }

        @Override
        protected int getLayoutRes() {
            return R.layout.adapter_offline_download_item;
        }

        @NonNull
        @Override
        protected DownloadViewHolder onCreateViewHolder(ViewGroup viewGroup, View view) {
            return new DownloadViewHolder(view);
        }

        @Override
        protected void onBindViewHolder(DownloadViewHolder holder, int i, Context context, Object o) {
            DownloadBean item = getItem();
            OfflineManager.DownloadTileInfo info = item.downloadTileInfo;
            holder.textTileName.setText(info.getTileName());
        }

        @Override
        protected long getItemId() {
           // don't have a valid id.
            return 0;
        }
    }

This is a nice library to use, thank you for your hard work! However the recent change has the side effect of adding lots of method count because of using Kotlin library I guess.

Can this be resolved in near the future? e.g. have a different branch which doesn't include kotlin.

Hi there, first of all i'd like to say thanks for making SimpleRecyclerView.

I noticed a strange issue recently. I've added cell.setOnCellClickListener2 in bind data which intents to a new window. Strangely, when I come back to the RecyclerView, that tapped item/cell moves to the top of the recyclerview. It's difficult for me to put it down in words but I hope you understand.

Initial load does not show any section headers.
Demo Code - https://github.com/ersin-ertan/Recycler @jaychang0917

Section headers that should be visible are improperly placed in between in position, but overlapping the views without the appropriate layout/spacing.

Scrolling the header off screen or scrolling to another header will show the header correctly.

Hi man, your lib is awesome. I've found an issue with autoloader.
I don't even know if it's a bug, autoloader doesn't work if all elements are visible. For example, I have endless list with 10 start elements on the screen. On the big screen these elements don't fill a whole screen, but I still expect recycler to call more elements to download, but it doesn't.
But it's ok if I SimpleRecyclerView#setLoadMoreToTop() with true flag.

hi love this library , one possible enhance is headers and footers , mostly for when the actual layout is grid and need a header to linear

SimpleRecyclerView has no addHeadView function，used like ListView

getCell and getAllCells are not updated.

I verified this with break points showing that the two get calls will occur before the MyCell.onBindViewHolder with the changedPayload, even when updateCell is called before the two gets.

recyclerView.updateCell(1, new Text("1000", 0));

        Log.i("GETAFTERUPDATE", ((TextCell) recyclerView.getCell(1)).getItem().text);

        int total = 0;
        for (SimpleCell sc : recyclerView.getAllCells()) {

Hi, dude! It's a really cool view, thank you for this!
But category for grid looks so strange. It's working only for full lines. For example, I have 2 columns in my grid. And if I add catagory after 3 elements, 4 elements added to this category too.
And can you add "multiselect" function?

hi,
I'm using this lib for section in recyclview but how to add search filter in list

Something like:
recyclerView.addCellInSectionHeader(int position, SimpleCell cell, SectionHeaderProvider provider);

Where position is relative to the section.
Insertion can take optional params of insert to top/bottom.

When i scroll my recycler view to end and scroll again to top, some item in the top change and become not correct. Please tell me if i miss something. Thank you!

Im using kotlin and have been following the guide in the readme.

Problem 1
I came across the section below in the readme and i cannot get it to work.

class BookCell(item: Book) : SimpleCell<Book>(item) {
  override fun getLayoutRes(): Int {
    return R.layout.cell_book
  }

  override fun onBindViewHolder(holder: SimpleViewHolder, position: Int, context: Context, payload: Any) {
    holder.textView.text = item.title
  }
}

Android Studio does not recognize textView in this line:
holder.textView.text = item.title

I did create the layout file and have a textView with the matching Id so im not sure whats going on.

I was under the impression that maybe you were doing some sort of compile time generation to generate the holder to be used based off of the layout file, but that cant be because com.jaychang.srv.kae.SimpleCell uses SimpleViewHolder explicitly which only extends com.jaychang.srv.SimpleViewHolder.

Problem 2
Cant create list of SimpleCell type in kotlin that is shown in the Multiple Types section of the readme.

List<Book> books = DataUtils.getBooks();
List<Ad> ads = DataUtils.getAds();
List<SimpleCell> cells = new ArrayList<>();

My version, In Kotlin

val books:MutableList<Book> = DataUtils.getBooks();
val ads:MutableList<Ad> = DataUtils.getAds();
val cells:MutableList<SimpleCell> = mutableListOf()

Android Studio is complaining about SimpleCell in the list declaration ( MutableList<SimpleCell> ) stating that I must add the Type argument.

One type argument expected for class SimpleCell<T>

I am very confused and would greatly appreciate it if you could provide a more detailed guide for using this library with kotlin and perhaps several kotlin example activities in the source.

I suppose for the time being i can write this in java but that also means other areas of my app that are already in kotlin will have to be converted back to java, which is a bummer. :(

When I hit a refresh button in my app to reload the SimpleRecyclerView with section headers, I use an AsyncTask to get the data to create the sections and cells. I run the .removeAllCells() onPreExecute, create the cells in the doInBackground, and add the cells to the recylerView in the onPostExecute. However, the recyclerView seems to do some sort of caching and adds an extraneous section to the beginning and then adds an extraneous cell to the end of each section after each refresh.

I've added images below for reference:

On initial load...

After first refresh...

After second refresh...

You can see the pattern, and it continues with each refresh. Any thoughts on how to solve this issue? Thanks

Something is really weird happening here, he object is always null!

Although, I tried to follow the exact way you did in the sample app but still, the object it null!
Anything I need to consider in here?

Thank you.

I use

ActivityOptionsCompat options = ActivityOptionsCompat.makeClipRevealAnimation(view, 0, 0, 0, 0);

to startActivity, but cell.setOnCellClickListener not have view. How to get view when use default cell. Thanks

When setLoadingMore(true) is called (which in turn calls showLoadMoreView()), a call to addCell method is added to the UI message queue and isLoadMoreViewShown is set to true.

If setLoadingMore(false) is called right after that, removeCell method is called immediately and isLoadMoreViewShown is set to false.

The problem is that at this moment the runnable that calls addCell is still in the message queue, therefore it will be called later. But when it's called, it adds this cell despite the fact that isLoadMoreViewShown is false. Now the cell is displayed, and it's not possible to hide it with another call to setLoadingMore(false), because hideLoadMoreView() thinks that it's already hidden.

does the add or update not work with simpleCell , because for these operation

 public void onNext(List<SimpleCell> value) {
                        new WeakHandler().postDelayed(() -> {
                            mSwipeRefreshLayout.setRefreshing(false);
                            if (value.size() > 0) {
                                mRecyclerview.addOrUpdateCells(value); // cannot resolve method 'addOrUpdateCells
                            }
                        }, 500);
                    }

Am getting cannot resolve method 'addOrUpdateCells
library version

Section Header cannot click

If you create a SimpleRecyclerView with an empty state view, it doesn't show the empty state view unless you add items first then remove them later.

I replicated with the sample project. If loadBookingsFromNetwork() is removed from the onCreate of EmptyStateViewActivity.java:

  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_empty_view);
    ButterKnife.bind(this);

    init();
    //loadBooksFromNetwork();
  }

Then when the activity is opened, the empty state view is not shown. Once you hit add then remove all, it will appear.

Hi, thanks for library!
But i have issue with section header in list. If I have Relative layout like view for header, it's showing wrong. It ssems like width = "wrap_content", although it match parent.
See screenshot. I use identical view for items and header.

Hello, I have a recycler view that displays list of different events, each event type is represented by different Cell type, however I would like to have section header that would group them by date. Currently I do not see a way to have one section header for multiple cells types.

Any advise welcome,
Thanks!

Hey,

I have and filter and I have to call notifiyDatasetChanged but its not working so I am called removeAll and then add new cells so cells are working fine, but headers are not working fine because my headers are also different so I have to call addRecyclerHeaders, headers names appears fine but there is blank space on above the headers. What I understand there is an space of previous headers.

Please lemme know how can I remove all headers too ?

I've found two problems with the documentation. First, the signature of onBindViewHolder is incorrect. The example code shows it as

onBindViewHolder(ViewHolder holder, int position, Context context, List<Object> payloads)

but it is actually

onBindViewHolder(ViewHolder holder, int position, Context context, Object payload)

Second, the example code uses Butterknife but does not mention anything about installing or configuring it. If this library relies on (or is intended to be used with) Butterknife, that should be explicitly called out. If it does not, then example code should be provided that does not require Butterknife.

When i move the last item from the bottom to top and then top to bottom with hight speed.
The order of item between first to the last be auto change and be wrong.

Do you have any idea why would that happen?

Hi again, thanks for fixes ! I think there's a bug with setLoadingMore(). I think there should be check if loading is already shown.

it seems that addOrUpdateCells() fails/crashes when the SimpleRecyclerView is empty.

at some point, the SimpleRecyclerView code checks for the mapping of type/name and since the recyclerview isempty (addCell or addCells not called) it crashes.

As a workaround, I have to add a dummycell at the initialization

Currently if your section SECTION A {1,2,3,4,5}, then adding element 0 will result in it being placed under the section view and not visible to the user. Perhaps instead of the views moving up with the addition, they could move down making room for the add element in the 0th spot.
