            Two adapters for one recycler view
            Asked 2020-Oct-09 at 04:22

            I have a bit of a dilemma. I'll try to explain it as simply as I can.

            My app has a page where I show a feed of posts through a recycler view (represented by the blue rectangles):

            This is simple enough, as I've created a PostAdapter class for the recycler view where I handle all the child view logic.

            Now I have another requirement where I need a page that shows a post (blue rectangle) at the top of the recycler view, and then the replies to that post below it (represented by the red rectangles):

            Please remember that the blue and red rectangles are simplifications. Each of these views has dozens of child views and hundreds of lines of code of logic each.

            I've created another class, ReplyAdapter, for the recycler view on this page, which handles all the logic for the replies.

            My problem now becomes: how can I also show the post (blue rectangle) at the top of the recycler view?

            I know that I can modify ReplyAdapter to allow for multiple types (as explained here), but because these are already two separate classes, each with their own complex logic, that's not really a possibility for me.

            So my question is: is there a way to keep the logic of the two adapters separate while still being able to use both under the same recycler view? If so, how? If no, what should I do?

            ...

            ANSWER

            Answered 2020-Oct-09 at 04:22

            If your use case is exactly this - data from PostAdapter on top, data from ReplyAdapter below - then androidx.recyclerview.widget.ConcatAdapter may help. As its name implies, it concatenates adapters.

            Android RecyclerView items empty when being swiped after switching apps
            Asked 2020-Sep-29 at 14:32

            First of all, I have looked at similar questions (for example, this one: Android RecyclerView ItemTouchHelper revert swipe and restore view holder). This already helped a great deal, until I - more or less, accidentally - noticed my current (and hopefully, final) issue with this screen of mine.

            Let's start with the setup:
            I have a fragment with a RecyclerView filled with some CardView items (it's a little fancier, but that's what is important right now). I also created an ItemTouchHelper with the implementation of SimpleCallback (nothing in onMove()) to make swiping the items (right) possible. For the record: I am using API 27 right now. So far, so good.

            What I want to achieve:
            I want to be able to swipe the items to be notified through the onSwiped() method of my SimpleCallback implementation. Also, I do NOT want the items to disappear, be removed, or otherwise taken out of my list of items in the RecyclerView. I just want to swipe them and have them return to their original position afterward (and yes, I know that it is sort of assumed that swiped items get removed). I am using the notifyItemChanged() method of my adapter in the onSwiped() method (also tried using notifyDataSetChanged()).

            The problem:
            Funnily enough, that works (mostly thanks to the aforementioned question) - until I hit that "app switch" button (don't know if there's actually one official name for it) and send the app to the background. Once I put it in the foreground again and start swiping, the items will not (visually) return. They are still on the list, and if I scroll or click the "app switch" button again, they will be displayed properly again (but won't return on swiping). Same if I navigate back one screen and come back to the list.
            That makes me think something happens when I send the app to the background and recover it. Something different than navigating to that screen (in which case everything works as intended) - which I thought would more or less produce the same results. Any ideas what I might be overlooking here?

            Answered 2020-Sep-29 at 14:32

            After some testing, I finally found the source of the issue:

            I had both the RecyclerView and its Adapter initialised through onStart() of the Fragment and not onViewCreated(). After changing that, I got the proper results I wanted.

            Lesson learned: Set your RecyclerView's Adapter as early as possible, unless you want to deal with sometimes strange issues.

            RecyclerView onScrolled method of addOnScrollListener not called except only once
            Asked 2020-Jan-11 at 15:14
            Background:

            I am implementing pagination logic with RecyclerView by adding addOnScrollListener function.

            Problem faced:

            The onScrolled method is called once when the RecyclerView adapter is loaded with dy value of 0. However when the list reaches its end when scrolled, the onScrolled method is not triggered while the onScrollStateChanged is triggered correctly.

            Here is my Adapter:

            Update onMove() changes in recycler view data to room database
            Asked 2019-Nov-01 at 09:50

            Following some articles, I am trying to create an android app with the following:

            • A recyclerview which fetches data from room database using live data.
            • Data structure is a list of custom objects with an attribute for ordering the data.

            Features in recyclerview:

            • Drag and drop for reordering data
            • Swipe to delete
            • UNDO action for swipe to delete

            Referred articles:

            1. Google codelabs for room database and live data
            2. AndroidHive article for recyclerview swipe to delete and undo to restore deleted item
            3. Medium post by Paul Burke for drag/drop in recycler view
            4. Medium post by Paul Burke for customizing dragged item in recycler view
            5. SO Post to detect drop event in recycler view

            My problem:
            Data reordering is not updated in the room library.

            Note:
            I am using an attribute for data ordering

            Please refer this GitHub repository if you need more details of the implementation.I have created a sample app for this question.
            (Adding complete code in question seems too long, kindly refer my github repository for the code)

            Please drop a comment if code of a particular file is required.I am not sure which code to post.
