A layout manager for the RecyclerView with interchangeable linear, grid, and staggered displays of views, all with configurable section headers including the sticky variety as specified in the material design docs.

Last update: Jan 2, 2023

Overview

SuperSLiM

This is the version 5 development branch.

What is Version 5

Version 5 is the current development branch for SuperSLiM. Once Milestone 3 is reached it will become the main branch for the library. Currently available from this branch are the following things:

an adapter implementation backed by a DAG
a layout manager that can layout a hierarchy of nested sections
a linear section layout
predictive animations for item changes
support for layout configurations; layout direction (LTR, RTL), reverse layout, stack from end, and horizontal and vertical layout configurations.
an example app
way too much work for what you see

What does it not yet have? Lots. See the project plan for more details, and support me on patreon.

Scrolling issues

Hi,

I think I found another issue:

I have a grid layout with variable size cards. If the first card in the last line is bigger than the rest it is cut off. Also I can't scroll back to the top in this case.

The layout item is completely displayed if I first scroll down and then turn the display (probably repainting the view)

Edit: I am using the width-based version of the grid layout. Edit 2: If I scroll fast enough I will get the complete item visible

Headers are displayed underneath the regular cards

Hi again!

I found another issue: Sticky headers are somehow displayed below my cards. this may have something to do with the elevation level of a card on Android 5, but I am really not sure.. Could you have a look at it and make sure that headers are always on top? (telling me what may be wrong is also an option ;) )

findFirstCompletelyVisibleItemPosition and findLastCompletelyVisibleItemPosition don't find anything.

The following stack trace occurs if I try to use the layoutManagers.findFirstCompletelyVisibleItemPosition to obtain the position of the first item on the screen.

java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.ViewGroup$LayoutParams android.view.View.getLayoutParams()' on a null object reference at android.support.v7.widget.RecyclerView$LayoutManager.getPosition(RecyclerView.java:5017) at com.tonicartos.superslim.LayoutManager.findFirstCompletelyVisibleItemPosition(LayoutManager.java:139)

I do not get a NPE if I switch the call to layoutManager.findFirstVisibleItemPosition().

I can use the later as a work around to obtain the position, but the former is preferable.

This is with version 4.12 of SuperSLiM.

Gridlayout ignores margins

Hi!

first of all: a nice library. A bit hard to setup, but the result is amazing!

I have a little issue: The GridSectionLayoutManager ignores the margin on my layouts.

I have some CardViews that use a layout_margin of 8dp in the topmost view. The default layoutmanagers in the RecyclerView support library recognize this margin and render the views accordingly. However your manager requires another view wrapped around it to make the margin visible.

Better handling of end-of-list removal

If notifyDataSetChanged() is called when the user has scrolled to the end of a long list, and several rows at the end of the list have been removed, the new list is laid-out improperly. You get a list that is scrolled past the end, presenting just white space. You can drag-down on the white space area and the tail-end of the list scrolls back into view.

The Android LinearLayoutManager handles this case by scrolling the list back to the first position, which isn't ideal, but it is better than scrolled past the (new) end.

Index out of bounds exception sometimes when updating the recylcer view
I am getting index out of bounds exception when I sometimes update the recycler view. All I am doing is

Replacing the dataset in the recycler adapter

Calling notifyDataSetChanged();

My getItemCount returns just returns the count of the dataset.

I am not sure if there is a bug in my code or not. I only started noticing this issue after around 0.4.4 (or some other release near that). Here is the crash log. I am using the latest version 0.4.7.

Sporadic NullPointerException in 0.4.5 on devices running KitKat

Using the the 0.4.5 release. This is happening for some of our users, but unfortunately we are unable to reproduce it, so it's hard to say why it's happening. All reports are coming from devices running KitKat (4.4.2 and 4.4.4) and this apparently happens upon loading the activity (or shortly thereafter?).

This stack trace closely resembles https://github.com/TonicArtos/SuperSLiM/issues/4, but we're obviously using a more recent version.

I will update this issue as soon as I can find more useful information (sorry it's so vague!), but I thought I'd report it in the meantime in case anyone has ideas.

Initialization thoughts.

I'd like to discuss the initialization process. Right now, the initialization code for SuperSLiM is a bit verbose:

layoutManager = new LayoutManager();
headerManager = new LinearSectionLayoutManager(layoutManager);
layoutManager.registerSectionLayoutManager(0, headerManager);
gridManager = new GridSectionLayoutManager(layoutManager, getActivity());
gridManager.setNumColumns(3);
layoutManager.registerSectionLayoutManager(1, gridManager);
recyclerView.setLayoutManager(layoutManager);

We currently have to initialize the all SLM's (including the default SLM's) ourselves, keep track of the index and correctly match these in our view binding/xml.

I would love to be able to do something like:

layoutManager = LayoutManager.enableLinearSLM().enableGridSLM(context, 3).addCustomSLM(new MySLM()).build()
recyclerView.setLayoutManager(layoutManager);

We could then use some sort of tag so then

final LayoutManager.LayoutParams lp = (LayoutManager.LayoutParams) holder.itemView.getLayoutParams();
lp.sectionManager = 0

would become something like

lp.setSLM(LinearSLM.tag)

I'm not sure how this would work via XML, but this shows exactly what SLM is being used without having to switch from your adapter to recyclerview implementation to match up ids.

Scrolling issue with Sticky Headers on

When you use this library with a RecyclerView that sits inside a swipe to refresh layout, or any other layout that handles vertical scrolling (i.e. a bottom sheet behavior), if you scroll up the list to the top and keep going, it will trigger the swipe to refresh or the bottom sheet dragging BEFORE the RecyclerView reaches the top of the list, so before it gets to the first header.

This issue seems to go away if I don't use the library, in both scenarios.

Is this covered by the Apache 2.0 License?

Hi,

I cannot find a license for this project here on GitHub. I would like to ask if there is one. There seems to be a project page here: https://tonicartos.nz/SuperSLiM/ in which you say that this is covered by the Apache 2.0 License. Is that correct. If so, would you mind adding the license file to the GitHub repo too? Thank you in advance.

Kind regards, Rafael

It looks like getChildAt(0) sometimes return null. Do we need to handle NPE here?

@Override public void onItemsUpdated(RecyclerView recyclerView, int positionStart, int itemCount) { super.onItemsUpdated(recyclerView, positionStart, itemCount); View first = getChildAt(0); View last = getChildAt(getChildCount() - 1); if (positionStart + itemCount <= getPosition(first)) { return; } if (positionStart <= getPosition(last)) { requestLayout(); } }

Version 5

Version 5 replaces all previous version of SuperSLiM. It is a complete and robust rewrite of the library fixing fundamental flaws that made SuperSLiM unworkable in version 4 and earlier. As older versions of the library are not compatible and are inescapably broken, they will not be updated in any form.

Version 5 introduces a new interface for both the adapter and section layout managers (SLMs). You do not have to use the provided adapter, if you wish to, you can implement your own adapter, the only requirement is to implement the AdapterContract interface. The interface for SLMs is not yet finalised, however the general layers of abstraction are. The intent is to make implementing SLMs as simple as possible, hiding as much complexity in the library as much as possible.

About this milestone

Milestone 1 is not yet a usable form of the new library, however, you can try out the new API and determine whether the new direction of the library is right for you. Currently implemented are the internal graph, an adapter, a nested linear layout without scrolling, and predictive animations.

Future development

The next milestone, Milestone 2, will be a usable library with support for nested linear sections, scrolling, and various header configurations. Milestone 3 and later will extend the utility of the library with things such as grid layouts, section footers, watchable events, and also other things like examples and tutorials. A roadmap is available on Trello.

v0.4.13(May 11, 2015)
Added tests and fixes for layout, scrolling, and find methods. Deprecated set methods on GridSLM, these will be removed in 0.5.

Due to pixel fitting on calculated columns, some grid columns and cells can be a slightly different width from others. In previous versions they were all the same, but could end out overlapping.

Fixed find first completely visible methods to actually find something (#88).

Fixed numerous minor layout bugs that resulted in views being attached just outside the viewable area.

Fixed a few layout bugs that resulted in some views overlapping by one pixel or being off by one pixel.
