QUESTION
My app consists in letting you add lists in which you can keep your notes. Therefore, I have this NotesListActivity where I can add and keep my Lists. I wanted to filter this lists following the https://www.youtube.com/watch?v=CTvzoVtKoJ8 tutorial and then I tried to adapt it to my code like below. Could you please tell me what is the problem here, cause I don't even get an error, I just not get any title of list as result. So, this is what I have in my RecyclerAdapter:
...ANSWER
Answered 2021-Jun-13 at 20:18The problem is that you are using an empty notesListAll list for filtering results; you need to populate it with the list of notes in the constructor
QUESTION
I am building an application where one of the pages has a webview. Currently the page has a the webview representable and a view. Webview is brought to the view using the UIViewControllerRepresentable. I am wondering firstly how when I tap the login button can I call a function inside the LoginWebview, and also secondly vice versa, how can I call a function in the LoginView from the LoginWebview. I currently have the set up so that when I click login it toggles the states which causes the updateUIView to trigger but how can I call a custom made function in there? And vice versa
Apologies for the long description above and if this a stupid question
Thanks :)

QUESTION
I'm diving into Kotlin Flow for the first time, and I'm wondering if with it ViewModel has a place anymore. ViewModel's advantage was that it was lifecycle aware and would automatically cancel subscriptions on the ViewModel's LiveData when the Activity gets destroyed. A Kotlin SharedFlow works similarly to LiveData in that it can be subscribed to by multiple observers. And in Kotlin a lifecycleScope coroutine should cancel all child coroutines upon the lifecycle ending. So if we had something like this:
...ANSWER
Answered 2021-Jun-13 at 06:40Keeping the whole discussion aside of LiveData vs SharedFlow or StateFlow. Coming onto ViewModels as you asked. If we are to go by documentation
The ViewModel class is designed to store and manage UI-related data in a lifecycle conscious way. The ViewModel class allows data to survive configuration changes such as screen rotations.
UI controllers such as activities and fragments are primarily intended to display UI data, react to user actions, or handle operating system communication, such as permission requests. Requiring UI controllers to also be responsible for loading data from a database or network adds bloat to the class. Assigning excessive responsibility to UI controllers can result in a single class that tries to handle all of an app's work by itself, instead of delegating work to other classes. Assigning excessive responsibility to the UI controllers in this way also makes testing a lot harder.
It's easier and more efficient to separate out view data ownership from UI controller logic.
I guess this sums it up quite well. It is true that lifeCycleScope can eliminate the need of ViewModel in a way, but ViewModel does more than just being a holder for LiveData.
Even if you want to use SharedFlow or StateFlow over LiveData I would suggest you still make use of ViewModel and inside it use a viewModelScope instead to still perform the usual and required separation of concerns between UI and data.
QUESTION
I am new into RxJava and I was under the impression that for each event each subscriber is being notified. So if we have N subscribers and a stream of X events the onNext for each of the N subscribers would be called. But when I run the following code:
ANSWER
Answered 2021-Jun-13 at 08:05RxJava sequences are synchronous by default thus the subscribe call above will run your emission code right there. To achieve the interleaving, you need a way to tell the source when both consumers are ready to receive. This can be done several ways:

As the title says, I'm trying to use swiperjs with Vue 2. I've used the API from swiper and another library "vue-awesome-swiper" to try and get it working. I get to the point with both approaches where everything appears functional but it's just the navigation buttons that aren't working and touch swiping is also disfuncitonal.
In each of the following approaches, I'm getting a seemingly perfect swiper but navigation is not working in either. I'm using vue 2.6 and swiper 6.7.
Here's what I have using vue-awesome-swiper:

ANSWER
Answered 2021-Jun-10 at 14:22you can use combineLatest:
combineLatest is an operator which you want to use when value depends on the mix of some others Observables. When an item is emitted by either of two Observables, combine the latest item emitted by each Observable via a specified closure and emit items based on the results of this closure.
