Hello ernestoyaquello,
It would be good if this repo had some sort of CI, so that we could see if there are any breaking changes.
Love
Yer best pal in the world
and your next of kin
Can we stop the drag at some point and when the user releases the dragging, there will be a button, and then, after clicking on the button, the action invokes?
Hi, first thank you for the wonderful lib
My question, is that any way to manipulate BehindSwipedItemLayout, for exemple i want to show and hide a progressBar onItemSwiped
private val onItemSwipeListener = object : OnItemSwipeListener<MyItem> {
override fun onItemSwiped(position: Int, direction: OnItemSwipeListener.SwipeDirection, item: MyItem): Boolean {
// Show loading view
Handler(Looper.getMainLooper()).postDelayed({
dataSet[position].status = "3"
Log.v("status : ", "3")
mAdapter.notifyItemChanged(position)
Log.v("delay : ", "2 Sec")
}, 2000)
// Hide loading view
return true
}
}Thank you!

What is wrong? I am using AndroidX
By the way the library is really well made. Thanks a lot for your effort!
I have 2 completely separated recyclers which are in different fragments in ViewPager. When I remove a swipe or drag flag from one of them it is automatically removed in the second which I find confusing.
Fragment 1:
recyclerOne.layoutManager = LinearLayoutManager(context!!)
recyclerOne.adapter = adapterOne
val orientation = DragDropSwipeRecyclerView.ListOrientation.VERTICAL_LIST_WITH_VERTICAL_DRAGGING
orientation.removeSwipeDirectionFlag(DragDropSwipeRecyclerView.ListOrientation.DirectionFlag.RIGHT)
recyclerOne.orientation = orientation
Fragment 2:
recyclerTwo.layoutManager = LinearLayoutManager(context!!)
recyclerTwo.adapter = adapterTwo
val orientation = DragDropSwipeRecyclerView.ListOrientation.VERTICAL_LIST_WITH_VERTICAL_DRAGGING
orientation.removeSwipeDirectionFlag(DragDropSwipeRecyclerView.ListOrientation.DirectionFlag.LEFT)
recyclerTwo.orientation = orientation
The above code will make both recyclers unswipable in either directions instead of making then swipable in different directions.
Hi is there a java example of this ? :) would be nice
Thanks for your great library.
I have implemented my fragments which shows live prices with your recyclerview.
But I have a problem with item long click listener.
The issue is that item long click events are not fired when refresh items per 500ms or less time.
How can I solve this issue?
Best.
I noticed a few things in your example app:
You set the divider and item_layout via XML, but at the same time, the BaseListFragment subclasses set the divider and item_layout programmatically. Should users follow this? If this is the case the README should be updated since the README only talks about setting it in via XML.
Should we implement the same logic found in onItemAddedListener in the BaseListFragment, in order to add new items to the RecyclerView? Specifically, I'm puzzled as to why you had to call adapter.insertItem(position, item)--does this mean the adapter doesn't hold a reference to the list that was passed to its constructor?
In fragment_vertical_list.xml, why are you setting behind_swiped_item_bg_color to @color/swipeBehindBackground, but on VerticalListFragment's setupLayoutBehindItemLayoutOnSwiping method, you are setting behindSwipedItemBackgroundColor to @null? Why are you duplicating the setting of the color?
Does this library support layout animation? I wonder if I'll be able to set custom grid animation with appear delay
I've been trying to use the recycler view within a NestedScrollView but it seems to lose all of the recycle-ability, I've searched around stack overflow and I've tried enabling/disabling isNestedScrollEnabled but doesn't seem to work.
Normal RecyclerView works just normal in nestedScroll View
I like this component but am not sure that it can be used with a PagedListAdapter. Do you know if can be?

Following the basic setup described in the readme, drag, drop, and swipe works well, but I noticed that when I do not continue with swiping and return the item to its starting position or if I release the item, the item background color remains set to behind_swiped_item_bg_color.
Item Click not working if whole item view passed into getViewToTouchToStartDraggingItem() for drag view. if there is not drag icon and whole view used for click as well as drag at the same time then item click listener will not be called.
Hi @ernestoyaquello,
I'm trying to integrate this with some workaround implementation of firestore adapter from Firebase UI samples. However, it gives me an error throwing out of bounds exception (since I cannot access the internal code of your library). It would be nice to have a firebase or firestore adapter support.
PS. I want to mention that I'm having fun using your library. Thank you for your impressive open-source work.
I implement this library to show the grid item with drag & drop feature. I want to disable that feature for the latest item.
Do you know any way to handle it?
Thank you.
I see that you made the adapter take in the dataset inside the constructor. Would it be possible to update this to include either the dataset in the constructor or use a method called updateDataset(list:Mutablelist){}. This would allow the use of DiffUtil in adapters. Would you be able to possibly add that as a method and allow the constructor list to be null-able?
list.scrollTo(..)
list.scrollToPosition(..)
linearLayoutManager.scrollToPositionWithOffset(..) also not working
Can you help me how to do this?
Currently, drag-n-drop isn't working quite well when one has different view types. You can still drag items of the same view type but when "jumping" from one to another the animation just cuts off.

Thanks for working on the swipe functionality. I have one further suggestion. Currently the library fires the ‘onItemSwiped’ callback and immediately removes the item from the array list. This makes it impossible to add undo/other functionality as I cannot intercept the delete.
I have pulled the library and simply deleted the ‘remove’ function call. I can then call ‘remove’ from my own app whenever I like. In my case I show a confirmation dialog in the onItemSwiped before calling remove.
Is there any way to change position only two list items (swipe only two) views. That means the the dragged one and the one where the dragged item is dropped.
Hi @ernestoyaquello
First of all thanks a lot for this wonderful library 👍
I've just started using it so I might miss something but I am using MaterialCardView for the list item layout - swipe background comes without corner radius on it 😞
It can be easily demonstrated in your sample app if you set the corner radius to 20dp (in list_item_vertical_list_cardview.xml) for example.
I've made a quick demo video on this:
In my code, I need to set the corner radius to 0dp to avoid such an issue 😞
Can you please help with this?
Spent a long time trying to decode the Kotlin example to work in Java, and still having troubles. At this point, i'm not sure if it's me, or it simply isn't compatible. A Java example would be useful.
It Would be helpful if you add
Short left swipe
Long left swipe
Short right swipe
Long right swipe
functionality separately

How to simulate:
Create a draggable adapter with at least 2 elements.
Quickly click on one and next on the other until the crash comes.
Please let me know if you need any further info or explanation.
I need this to be fixed. Thanks in advance!
As far as I've seen from the code, onScrolled(RecyclerView recyclerView, int dx, int dy) is used for onListScrolled(scrollDirection: OnListScrollListener.ScrollDirection, distance: Int).
But onScrollStateChanged(RecyclerView recyclerView, int newState) is unsued.
What about adding a new method to the listener to indicate changes in the state of the scroll? I think the changes in the code would be pretty small.
This feature could be helpful in some situations.
Looking forward to feedback.
I want to disable swipe on some screen programmatically?unable to do this
Can I use DragDropSwipeRecyclerview in conjunction with LiveData in the room?
I'm inquiring because DataSet is in List format.
I am trying to move an item from one recyclerview to another vertically but I can't do it and I don't see any example, any idea?
I want to Implement Partial Swipe to show delete Button , and OnClick Of Button to Perform Action. How can I do that in this library.
can we use this adapter without inheritance. I mean I must use composition. How to do that
When link I click no web app opens
Hi, my divider is not displayed and everything that should appear in the background (icons and color). Swipe works, but when the swipe does not appear the icon and the background color, as well as the listeners do not work. I specified parameters both through the XML and in the code. Nothing has changed. Perhaps this is due to the fact that the list is inside in ViewPager?!

I faced a strange bug. I have grid recycler (3 cols) with for example 50 draggable and 50 non-draggable items. When I'm dragging an item to the botom and release after the point where last draggable item goes out of the screen and gets recycled, scroll up to the place of last draggable position (where my dragged view is located now), I'm seeing 3 empty cells
Hey, is it possible only to allow swiping in one direction (primary or secondary)? Possibly they could be renamed to Left/Right or Start/End to follow convention?
Also it would be great if the Adapter would feature the DiffUtil ListAdapter for nice animations :)

Whenever the list pull pulled from top to bottom, new data set is called and that in turn calls 'setupRecyclerView' and provides it with new data list and as soon as I refresh the list, both the behindSwipedItemLayout disappears and I get empty background when swiped.
Hi!
The first thing I want to mention is it would be nice if you add an option to start dragging on long click (where the current touch listener in TouchHelper is)
Also it'd be a great thing if you add a feature to animate dragged view (kinda DragViewAnimator interface) (For example to scale view up on drag started and down on ended)
I need to send the new items positions to server
This happens to me when I delete items from my data source (LiveData) and then I try to update the dataSet.
viewModel.items.observe(this@MyFragment, Observer { adapter.dataSet = it })
Also if you try to move the opaque item, his opacity will become normal again.
This does not happen when you use the default behavior of the swipe, which as far as I've seen uses removeItem(position: Int)
On the other hand, when adding an item everything seems to be ok.
I'm not sure this happens. I will try to reproduce it in a smaller project asap.
Hello,
maybe I've not really gotten it but I can't create a grid view with 5 columns and 2 rows.
mList.numOfColumnsPerRowInGridList = 5 or mList.numOfRowsPerColumnInGridList = 2 don't have any effect.
Any hints are appreciated.
My recycler, receives some different types of item views, in my current implementation, I use the viewType inside onCreateViewHolder, to differentiate and inflate different layouts. I wonder if it is possible to do this with your library?
Confused, this seems to extend RecyclerView 1.2x, but it's missing getBindingAdapterPosition()
Seems to default to both directions but hoping for right to left only. Looks like something to do with the ListOrientation but cannot figure out the Java syntax.
In my OnCreateView fragment, I am setting these properties based on a "lock UI" preference, which prevents swiping left/right/reordering.
In short, I need to restart the activity for this to take effect, it doesn't work setting this within the fragment OnCreateView, even though the code paths are being executed at the expected time. Is there something else I need to do here, or is this a bug?
Thanks.
_binding.list.setOrientation(DragDropSwipeRecyclerView.ListOrientation.VERTICAL_LIST_WITH_VERTICAL_DRAGGING);
if (PreferenceManager.getDefaultSharedPreferences(getContext()).getBoolean("UI_LOCKED", false))
{
_binding.list.disableSwipeDirection(DragDropSwipeRecyclerView.ListOrientation.DirectionFlag.LEFT);
_binding.list.disableSwipeDirection(DragDropSwipeRecyclerView.ListOrientation.DirectionFlag.RIGHT);
}
else
{
_binding.list.enableSwipeDirection(DragDropSwipeRecyclerView.ListOrientation.DirectionFlag.LEFT);
_binding.list.enableSwipeDirection(DragDropSwipeRecyclerView.ListOrientation.DirectionFlag.RIGHT);
}
