QUESTION
I am developing a mobile application using Xamarin.Forms
, and for testing purposes I am trying to read a local json
file and displaying its contents into a CarouselView
. However, I am not able to do it: I am correctly parsing the file, but then it is not showed in the UI.
The xaml
code (with only the CarouselView
part) is as follows:

QUESTION
I have a problem in a Xamarin.Forms application that I am developing. I need to read the content of a .json
file, to be showed in a CarouselView
. I am using Newtonsoft.Json
library to parse the file.
However, it continously gives to me an error that it cannot find the file. The c#
code is as follows:
ANSWER
Answered 2022-Feb-24 at 12:58I would suggest the following points:
in Visual Studio, it's possible to copy a file in the output folder. Please check the property windows when you click on the JSON file. Maybe it will not copy to the bin folder where your EXE or code is running.
Before you are starting with DeserializeObject, I would check the path if the file really exists. File. Exists() Method.
When you access the file, check if you are in the right folder. Maybe your file is in another subfolder, and you are one folder above.
For accessing, use total paths to avoid issues.

I have a running XF App with a lot of database accesses through an Azure API. So far all was running quite well. Due to layout changes I changed to a shell based navigation. I worked through the whole stuff but faces a huge problem. My app.xaml.cs is loding a lot of controllers:

I would like to know how to deal with an error in CarouselView in Xamarin. I have written the following in Xaml and linked it to a group of photos.
...ANSWER
Answered 2022-Jan-28 at 06:29I would suggest you try the plugin : https://github.com/luberda-molinet/FFImageLoading .
Use CachedImage instead of built in Image
, since it would display a default placeholder image if the load is failed ,so in this case it will not crash .
QUESTION
I am using Xamarin.Forms OxyPlot Chart. I have a collectionview and in each collectionview item has an expander and inside each of those expanders is a PlotView
...ANSWER
Answered 2021-Dec-16 at 03:10See github ToolmakerSteve / repo OxyplotApp1, for working version.
"This PlotModel is already in use by some other PlotView control"
After various tests on iOS, I conclude that using (CollectionView or ListView) + Expander + Oxyplot on iOS is fundamentally not reliable.
Oxyplot seems to worsen known issues with Expander and CollectionView.
Therefore, the most important fix is to stop using these collection views. Replace use of CollectionView
with:

QUESTION
I'm trying to use CarouselView to create a horizontal ListView since a client of mine does not like the vertical ListView I have implemented in their project. I tried to follow several tutorials, but to no avail.
I have a hunch that the issue is with the nuget packages I downloaded or with the namespace I'm using in the xml. I am using Visual studio 2019 in a Xamarin Android App.
Here is a list of nuget packages I downloaded for the Carousel View:
CarouselView
CarouselView.FormsPlugin
CarouselView.FormsPlugin.Fix
Xamarin.Forms v5.0.0.2083
Here is the code in my content_main.xml
...ANSWER
Answered 2021-Sep-06 at 06:36From document What is Xamarin.Forms? ,we know that
Xamarin.Forms is an open-source UI framework. Xamarin.Forms allows developers to build Xamarin.Android, Xamarin.iOS, and Windows applications from a single shared codebase.
Xamarin.Forms allows developers to create user interfaces in XAML with code-behind in C#. These interfaces are rendered as performant native controls on each platform.
At runtime, Xamarin.Forms utilizes platform renderers to convert the cross-platform UI elements into native controls on Xamarin.Android, Xamarin.iOS and UWP. This allows developers to get the native look, feel and performance while realizing the benefits of code sharing across platforms.
So, you can use Xamarin Forms controls (CarouselView
) in forms'app,and deploy the app to your android devices or ios devices.
From above description you posted, I think you're confused about CarouselView
's usage.
Since the CarouselView
is a control of xamarin form, you should use it in xamarin forms's app rather than referencing it in Android.
For how to use CarouselView
, you can refer to the official document : Xamarin.Forms CarouselView.
And there is a sample(Xamarin.Forms - CarouselView) included in this document, you can download it and deploy it to your android device which will help you understand it better.
