I am struggling to get my item centered in the carousel view, as simple as this sounds for same reason the item always starts at starts.
I need to display the items one at the time.
<StackLayout x:Name="innerStack"
HorizontalOptions="CenterAndExpand">
<Label Text="tesyt"
HorizontalOptions="Center"
VerticalOptions="CenterAndExpand"></Label>
<CarouselView HorizontalScrollBarVisibility="Never" BackgroundColor="Blue"
x:Name="carousel"
HorizontalOptions="CenterAndExpand"
VerticalOptions="CenterAndExpand"
HeightRequest="500"
> <CarouselView.ItemsLayout>
<LinearItemsLayout Orientation="Horizontal" ItemSpacing="0"/>
</CarouselView.ItemsLayout>
<CarouselView.ItemsSource >
<x:Array Type="{x:Type Label}">
<Label Text="tesyt" TextColor="Green" Margin="10,0,0,0"
></Label>
<Label Text="tesyt" TextColor="Brown"></Label>
</x:Array>
</CarouselView.ItemsSource>
</CarouselView>
</StackLayout>
I am struggling to get my item centered in the carousel view。
If you want to set item center in carouselview, you can set HorizontalOptions="CenterAndExpand" and VerticalOptions="CenterAndExpand" for item in carouselview datatemplate.
And I find there are some error for carouselview.itemsource, you can refer to x:Array markup extension firstly, you can also take a look the following code:
<CarouselView
x:Name="carousel"
BackgroundColor="Blue"
HeightRequest="500"
HorizontalOptions="CenterAndExpand"
HorizontalScrollBarVisibility="Never"
VerticalOptions="CenterAndExpand">
<CarouselView.ItemsLayout>
<LinearItemsLayout ItemSpacing="20" Orientation="Horizontal" />
</CarouselView.ItemsLayout>
<CarouselView.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>mono</x:String>
<x:String>monodroid</x:String>
<x:String>monotouch</x:String>

I am using a stack layout as its the easiest with responsive but I am trying to get to items side by side I am trying to mimic running apps with speed and distance.
My Main question is how would one get the speed and distance to look similar to the design I can't get the spacing right in a stack layout
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="WellbeingNinja.Views.BmiInfo">
<ContentPage.Content>
<StackLayout Orientation="Horizontal" Spacing="0" Padding="0" VerticalOptions="StartAndExpand">
<Frame x:Name="frameTotalSpeed" CornerRadius="7" >
<StackLayout>
<Label x:Name="lblSpeedText" Text="Distance"></Label>
<Label x:Name="lblSpeed" VerticalTextAlignment="Center" HorizontalTextAlignment="Center" Text="0.00" FontSize="Large" ></Label>
</StackLayout>
</Frame>
<Frame x:Name="frameTotalDistance" CornerRadius="7">

<Label x:Name="lblDistance" VerticalTextAlignment="Center" HorizontalTextAlignment="Center" Text="0.00" FontSize="Large" ></Label>

I am trying to mimic this style here
use a Grid
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50*" />
<ColumnDefinition Width="50*" />
</Grid.ColumnDefinitions>
<Frame Grid.Column="0" x:Name="frameTotalSpeed" CornerRadius="7" >

I need to set the height of the list view so that the bottom view cell is not cut off whenever adding or removing a view item. I can achieve it for some iPhone models, but not the others. It seems it’s not a right way to achieve it by iPhone model. My questions are:
1. On some iPhone models, why the top position shifts down by about 25 pixels after adding a view item?
2. How to find the absolute top position Y coordinate of the list view?
It seems AbsoluteLayout.LayoutBounds="0,0,1,1" AbsoluteLayout.LayoutFlags="All" doesn’t help. VerticalOptions="Start" doesn’t help either.
Note:
1. no such an issue on Android phones.
2. Observation only: It seems that changing the margin of the listview header brandStack has no effect on the layout, eg. cannot see increased margins.
3. The following two screenshots show that the top position of the listview header has moved down a bit after an item is added to the listview.

The top position shifts down because the margin you set in the listView:
<ListView BackgroundColor="Orange" Margin="15">
Remove the Margin="15" and the space will disappear.
BTW, you can add page-safe-area-layout to make it looks better:
<ContentPage ...
xmlns:ios="clr-namespace:Xamarin.Forms.PlatformConfiguration.iOSSpecific;assembly=Xamarin.Forms.Core"
Title="Safe Area"
ios:Page.UseSafeArea="true">
<StackLayout>
...
</StackLayout>

I am trying to create layout similar to Android cardview.
My progress for now.

As you can see It looks guide well. However when I change Image property Aspect="Fill" to Aspect="AspectFill" images would lost round corners.

My code
<Frame
VerticalOptions="Start"
Margin="8"
CornerRadius="10"
Padding="0"
BackgroundColor="White"
IsClippedToBounds="False">
<StackLayout Spacing="0">
<Image
HeightRequest="150"
Source="{Binding ImageUrl}"
Aspect="AspectFill"
/>
<StackLayout

Is there solution to have Image with property Aspect="AspectFill" and with rounded corners?
I have Xamarin Forms Cross Platform project with a ListView whose ViewCell contains a StackLayout. I hide and show the StackLayout when the user clicks on an image. There is a known issue with the ViewCell not resizing correctly on iOS and solution I found was to use ForceUpdateSize method on the ViewCell in order to for the app on iOS to resize the cell. This is working from the aspect of resizing the ViewCell - however after calling the method, I loose the three buttons at the bottom of ViewCell. The buttons are in a grid and all the code, xaml and screen shots are below. Any help with resolving this would be greatly appreciated.

Show Details code from the View Model
public void ShowDetailText(long pl_PlaceID)

try

if (lobj_Place != null)

}
catch (Exception ex)

App.ProcessException(ex);
}
}
Any suggestions would be greatly appreciated.
No one every really responded to my post so I started looking for other controls to use. I found SyncFusion had a ListView control also. It seemed to be a pretty easy drop in for the Xamarin Forms ListView control (add the needed namespace and prefix all the controls with the SyncFusion ListView namespace). On iOS you still needed to call extra code when the size of the list item entry expanded but the SyncFusion code seems to work cleaner than the Xamarin code as the problem did not manifest when using the SyncFusion ListViewcontrol.
Here is the code I had to include in the code behind for the page in my PCL project. (lvPlaces is the name of my ListView control in the XAML)
if (Device.RuntimePlatform == Device.iOS)
{
lvPlaces.ForceUpdateItemSize();
}
