QUESTION
I'm doing a Group Chat with Firebase and currently I'm using a RecyclerView to display chat messages and I'm having a problem. When you open the app in the fragmented home and you go to chat activity and start chatting (adding elements to recycler view) all goes fine. But, when you go via the NavigationDrawer to another fragment and get back to the chat fragment using again this Navigation Drawer. When you add one element in the chat it appears all in the blank it just displays the last message. Anybody knows why does this happens?
Here I leave the RecyclerView Adapter Code:
...ANSWER
Answered 2021-Jun-15 at 13:55To solve your problem you can just remove the OnResume method because you are initializing the array every time you change between fragments and that is the problem.

I have this code inside which I'm calling "makeView" function that returns a View, and in the makeView function I'm incrementing the variable "id" and passing it to the View, but when I do this it shows this error
"Updating a preview from SongsList_Previews in SongBook.app (2935) took more than 5 seconds."
And surprisingly when I comment out the line "self.id += 1" everything works. I'm new to SwiftUI, so forgive me if I left out some information.

I'm developing a simple navigator with mapbox API for Android.
I'm creating some routes using https://docs.mapbox.com/playground/directions/ playground and i would like to use the generated JSON to generate a DirectionsRoute object.
So i call DirectionsRoute.fromJson() but when i do it, the application crashes with this error:

QUESTION
I'm trying to use NavigationLink's isActive variable to pop back to the root view controller.
The problem I'm experiencing is that using isActive pushes the wrong row when clicking on a list item. Remove the isActive variable and everything works as expected.
Here's some example code for demonstration purposes:
...ANSWER
Answered 2021-Jun-14 at 21:41Because activateNavigationLink is just a Bool in your code, if it is true, every NavigationLink will register as active in your List. Right now, this is manifesting as the last item (C) getting pushed each time.
Instead, you'd need some system to store which item is active and then translate that to a boolean binding for the NavigationLink to use.
Here's one possible solution:
QUESTION
I'm hoping that I can attach a recording of my simulator to this request. I have a list of items that I create a NavigationLink for that call a child view with different data based on a value passed in. The child view is a large horizontal scroll view with pages that support months of the year. DragGesture controls the positioning of the horizontal scroll.
When I transition from the List to the child view it appears almost like it is swooping in from the right and when it transitions back to the parent list view you can see visual from both views appear briefly during the transition.
I believe it has something to do with the GeometryReader and Horizontal Scroll view, but can't figure out how to stabilize it...
The list view is:

Answered 2021-Jun-14 at 16:02Currently you are using a custom horizontal carousel view(or custom PageTabView etc.), but using TabView with PageTabViewStyle() is easier, unless you want a special animation.
