I am using the Paging 3 Library with Lazy Column and a BottomNavigation Menu in my Activity. Each Composable Screen attached to the BottomNavMenu uses a Composable that in turn uses Lazy Columns. When I navigate between the Composables using the compose navigation library I want the recomposed composable to retain the scroll position and the lazyListState
I have tried the following but doesn't work:

Answered 2021-May-05 at 13:39You probably need to do collectAsLazyPagingItems()

QUESTION
I recently found myself writing the following code:
...ANSWER
Answered 2021-Apr-19 at 15:00When you use ::listener
, you are sort of creating an anonymous class that implements the interface, each time. However, as your test shows, the .equals
of the anonymous classes will return that they are equal, which usually wouldn't be the case with an anonymous class (created with object:
syntax). So, two instances created using ::listener
will be equivalent with ==
but not with ===
.
Sets typically use .equals
equality (==
) to determine if an instance is a duplicate, but it's possible to create a Set backed by IdentityHashMap so it effectively behaves as a Set using identity comparison. This breaks the Set contract, but a class could be using it internally for some reason.
Whether it is safe to use this depends on whether the class you're working with compares listener instances by .equals
or identity. If it's possible it's using an IdentityHashMap to store and compare listeners, then this is not safe.

I am trying to save data into async storage every time when data in redux store changes, But I am getting an error when I am trying to update user's Name and saving it then I am able to see the changes when Application is open but when I close the application and open it again then it is showing the Old User's Name that I have updated.
For example if my current Name is "Aviansh" and I have updated it to "Anshu" then I am to see "Anshu" when Application is open but when I close the application and open it again then I am able to see "Avinash" again that is not expected
Code for saving Data in Local Storage
...ANSWER
Answered 2021-Mar-29 at 12:24You have mentioned in the comments that you use redux-persist
, but in the code sample you have posted, there is no redux-persist
setup - this is what you are missing.
There is no need to save/load the data from async storage manually if you are using redux-persits
, just follow the instructions in the package readme carefully.
QUESTION
Hello Guys im using Android Jetpack Paging library 3, I'm creating a news app that implements network + database scenario, and im following the codelab by google https://codelabs.developers.google.com/codelabs/android-paging , im doing it almost like in the codelab i almost matched all the operations shown in the examples https://github.com/android/architecture-components-samples/tree/main/PagingWithNetworkSample.
It works almost as it should...but my backend response is page keyed, i mean response comes with the list of news and the next page url, remote mediator fetches the data, populates the database, repository is set, viewmodel is set...
The problem is : when recyclerview loads the data , following happens:recyclerview flickers, items jump, are removed , added again and so on. I dont know why recyclerview or its itemanimator behaves like that , that looks so ugly and glitchy. More than that, when i scroll to the end of the list new items are fetched and that glitchy and jumping effect is happening again.
I would be very grateful if you could help me, im sitting on it for three days , thank you very much in advance.Here are my code snippets:
...ANSWER
Answered 2021-Mar-19 at 18:15Just following up here from comments:
Setting pageSize = 10
fixes the issue.
The issue was with pageSize
being too small, resulting in PagingSource
refreshes loading pages that did not cover the viewport. Since source refresh replaces the list and goes through DiffUtil
, you need to provide an initialLoadSize
that is large enough so that there is some overlap (otherwise scroll position will be lost).
BTW - Paging loads additional data automatically based on PagingConfig.prefetchDistance
. If RecyclerView
binds items close enough to the edge of the list, it will automatically trigger APPEND / PREPEND loads. This is why the default of initialLoadSize
is 3 * pageSize
, but if you're still experiencing additional loads, I would suggest either adjusting prefetchDistance, or increasing initialLoadSize
further.
QUESTION
I have a RecyclerView that uses a PagingDataAdapter to show its items. On initial load of the entire page, I want to show a Shimmer loading placeholder. However, when I try to do this, the loading placeholder also shows up for a small content change of a single item. This makes the entire screen flicker because it hides the RecyclerView during loading and reshows it once the content change has been loaded. I don't want the loading placeholder to show for a single content change.
I am checking the loading state in the load state listener for the adapter:
...ANSWER
Answered 2021-Mar-13 at 21:40Are you using RemoteMediator
? If so, you can just observe changes to CombinedLoadStates.mediator.refresh
. CombinedLoadStates.refresh
is just a helper which combiens both mediator + source states for "common" use-case.
If you're only using PagingSource
and updating DB / invalidating separately from RemoteMediator
, you can also check against adapter.itemCount
to determine "initial load".

QUESTION

This website originally had one filter, but I added another one, wanting each of them to work independently (i.e. filter by category (events), and also filter by states).
It seems it's still acting as one filter, as in I can only select one variable between the two filters set up. How can I adjust the functions so each filter operates independently?
...ANSWER
Answered 2021-Jan-17 at 08:50First of all, you have a duplicate function showAllProducts
, which you have also linked to two different buttons. I suppose you intended to have two different functions, one for each "All" button, so add a function called showAllEvents
and another showAllStates
, and reference those as button handlers.
On the question: you should move the filtering to one function which will take the two filters into account. You could use this.title
and this.titleState
to perform the filtering, making sure you treat the "All" case correctly.
So the filtering functions, which you bind to your HTML, should become:

Install loadState
You can use loadState like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the loadState component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
