SwipeToRefresh | Simple swipe to refresh view | Android library

In my app, I added a swipe down reload in kotlin, and It works. When you swipe down, it shows the refresh widget and then goes back up and starts to refresh the page. But it takes my app a few seconds to refresh since It's refreshing a website. Does somebody know how to only make the refresh widget go back up once the refresh is done?

Here's my code:

MainActivity.kt:

I'm trying to add a swipe down reload to my app in Kotlin. So to do this, as usual, I followed a tutorial. But I'm getting the error: Unresolved reference: setOnRefreshListener and Unresolved reference: isRefreshing Here is my code:

MainActivity.kt:

I have a RecyclerView that gets filled with paginated data.

I need to be able to refresh it via SwipeRefreshLayout, but so far, I am unable to do so.

I have tried plenty references that does similar to this, but without any success. Also, for letting you guys know, When I do refresh, the data gets retrieved correctly, but it is not being displayed on the recyclerView...

Also, when I move from that destination to another via Navigation and then, I hit back, it gets updated. I am not sure what I am missing or what I am doing wrong.

ViewModel:

I have Recyclerview showing media but when I scrolls items flickers or vibrates. I have tried many options mentioned in post like

My xml code :

I developed an android application in which I want to get data from the database without refreshing the app. I tried different methods but no one works for me. I am using PHP for fetching data from the database into my android app. Below is my code which is for now only fetching data from a database but I have to refresh the app if I update data in the database to get the updated value in the app. I want realtime values from the database, like, if I update data in the database, I want the same update in the app but without refreshing it.

The issue with reactive programming patterns for one-time events is that they may be re-emitted to the subscriber after the initial one-time event has occurred.

For LiveData the SingleLiveEvent provides a solution using an EventObserver which may also be applied to Kotlin Flow.

Can an AsyncSubject observable be created to handle the case of the SingleLiveEvent in RxJava? The main issue seems to be if there a way for an AsyncSubject to be manually "re-opened" to re-emit data after onComplete is called?

AsyncSubject seems like a potential solution for RxJava, without creating an EventObserver, as the documentation states that it will only publish it when the sequence is completed.

A loading boolean is emitted from the ViewModel method initFeed and view effect state to the view, a fragment in this case. The loading boolean works as expected on the initialization of the fragment and ViewModel sending true via onNext, and completing with onComplete on either a successful or erroneous attempt.

However, the attempt to re-emit a value fails when for example a swipe to refresh initiates the same initFeed method. It seems that onNext cannot be used after onComplete is called for the same object.

I got the following problem: I'm making an android webview app using fragments, and I want to implement a SwipeToRefresh action.

I tried to do it, but the app stops immediately after user's pull-to-refresh action. Here are different codes:

fragment_home.xml :

I'm looking to refactor an immutable view state's values in the Android ViewModel (VM) in order to do the following:

1. Update the view state in the VM cleanly without copying the entire view state
2. Keep the view state data immutable to the view observing updates

I've built an Android Unidirectional Data Flow (UDF) pattern using LiveData to update the view state changes in the VM that are observed in the view.

See: Android Unidirectional Data Flow with LiveData — 2.0

Full sample code: Coinverse Open App

The existing implementation uses nested LiveData.

• One LiveData val to store the view state in the VM
• Nested LiveData for the view state attributes as immutable vals

I have an AppBar and RecyclerView in CoordiantorLayout. SwipeToRefresh has to be fullscreen but RecyclerView not scrolling down then.
