Here is a screenshot of the problem (Left= Xamarin.Forms previewer; Right= ADV 768x1080)
Code:
<Frame BackgroundColor="#292929" VerticalOptions="CenterAndExpand" Margin="20,0,20,0" CornerRadius="4" Padding="0">
<StackLayout Orientation="Vertical" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" Padding="5">
<StackLayout Orientation="Horizontal" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" BackgroundColor="Tomato">
<Label FontSize="Small" Text="ABBONAMENTO 30 giorni" TextColor="White"/>
<Label FontSize="Small" Text="€10,99" HorizontalOptions="EndAndExpand" TextColor="#ff9900"/>
</StackLayout>
<Button HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" Text="ISCRIVITI" TextColor="#eeeeee" BackgroundColor="#FF9900" CornerRadius="4"/>
</StackLayout>
</Frame>
The frames are put in a StackLayout, which parent is a Grid.
The problem persists on low resolution devices only.
Can you tell me why is this happening, and how to fix it?
I need this layout to be height-aware and responsive.

I do have the following XAML code. And the output is as shown below in the picture. How can I achieve to fill the image within its grid in the frame? Thank you for your help.
<CollectionView.ItemTemplate>
<DataTemplate>
<Grid Padding="10,20,10,0">
<Frame
Margin="5"
BackgroundColor="AntiqueWhite"
CornerRadius="20"
HasShadow="True"
HeightRequest="200"
HorizontalOptions="FillAndExpand">
<Grid RowDefinitions="7*,3*">
<Image
Grid.Row="0"
x:DataType="products:PopularProduct"
Aspect="AspectFill"
HorizontalOptions="FillAndExpand"
Source="{Binding FullImageUrl}"
VerticalOptions="FillAndExpand" />
</Grid>
</Frame>
</Grid>
</DataTemplate>
</CollectionView.ItemTemplate>
I would make use of StackLayout with something like this
<CollectionView.ItemTemplate>
<DataTemplate>
<StackLayout
HorizontalOptions="FillAndExpand"
Orientation="Horizontal"
VerticalOptions="FillAndExpand">
<Frame
Margin="10,20,10,20"
Padding="0"
BackgroundColor="AntiqueWhite"
HasShadow="False"
HeightRequest="200"
HorizontalOptions="FillAndExpand">
<StackLayout Orientation="Vertical">
<Frame
Padding="0"
CornerRadius="20"
HasShadow="True"
IsClippedToBounds="True">
<Grid RowDefinitions="7*,3*">
<Image
Grid.Row="0"
x:DataType="products:PopularProduct"
Aspect="AspectFill"
HorizontalOptions="FillAndExpand"
Source="{Binding FullImageUrl}"
VerticalOptions="FillAndExpand" />
<StackLayout
Grid.Row="1"
Margin="10"
Orientation="Vertical">
<Label Text="Any label if you want here" />
</StackLayout>
</Grid>
</Frame>
</StackLayout>
</Frame>
</StackLayout>
</DataTemplate>
</CollectionView.ItemTemplate>
I have a problem. I recently had this problem: Xamarin forms Add button in TabbedPage, but that is fixed using the accepted anwser. In short, I am using a CarouselView and an IndicatorView, so I can have an overlay over multiple screens. Both the views replace my TabbedPage, but the IndicatorView needs to look like the TabbedPageBar. The only good page about styling an IndicatorView was this one: https://learn.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/indicatorview.
Here is the page I have:
<StackLayout AbsoluteLayout.LayoutBounds="0,0,1,1"
AbsoluteLayout.LayoutFlags="All"
Padding="0"
Spacing="0">
<IndicatorView x:Name="indicatorView">
<IndicatorView.IndicatorTemplate>
<DataTemplate>
<StackLayout HorizontalOptions="FillAndExpand">
<Frame Margin="10">
<Label/>
</Frame>
</StackLayout>
</DataTemplate>
</IndicatorView.IndicatorTemplate>
</IndicatorView>
<CarouselView ItemTemplate="{StaticResource templateSelector}"
IndicatorView="indicatorView">
<CarouselView.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>1</x:String>
<x:String>2</x:String>
<x:String>3</x:String>
</x:Array>
</CarouselView.ItemsSource>
</CarouselView>
</StackLayout>
Now how can I let the IndicatorView look like a TabbedPageBar?
I think the key point here is remove the Shadow and CornerRadius of Frame, then you can customize the layout in the Frame. Here is an example:
<IndicatorView x:Name="indicatorView" >
<IndicatorView.IndicatorTemplate>
<DataTemplate>
<StackLayout HorizontalOptions="FillAndExpand" Spacing="0">
<Frame HasShadow="False" CornerRadius="0">
<StackLayout Orientation="Vertical">
<Image Source="Images"/>
<Label Text="123" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand"/>
</StackLayout>
</Frame>
</StackLayout>
</DataTemplate>
</IndicatorView.IndicatorTemplate>
</IndicatorView>
I have implemented a listview and in each item I want to have two labels, in each end horizontally. But in reality it just put the two labels next to eachother left aligned.
I read that maybe this is not possible with a stacklayout, as it doesn't take up more space than needed. (Even tried fill and fillandExpand which didn't help.)
Instead I should use a grid. But I have options on my listview, as grouping, refresh, caching, tapped, which I guess I don't have on a grid?
I would like to succeed with a listview if that is possible. Anyone have some insights to this layout issue?
Here is my xaml code:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="MyApp.Page.ItemsTest">
<ListView x:Name="ItemView"
ItemsSource="{Binding ItemGroup}"
CachingStrategy="RecycleElement"
IsGroupingEnabled="true"
HasUnevenRows="True"
ItemTapped="Handle_ItemTapped">
<ListView.GroupHeaderTemplate>
<DataTemplate>
<ViewCell>
<StackLayout BackgroundColor="#FFA500" Orientation="Vertical" Padding="10">
<StackLayout Orientation="Horizontal">
<Label Text="{Binding Heading}" TextColor="White" FontAttributes="Bold" />
</StackLayout>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.GroupHeaderTemplate>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Orientation="Horizontal" Padding="10" HorizontalOptions="FillAndExpand">
<Label Text="{Binding Name}" FontAttributes="Bold" HorizontalTextAlignment="Start"/>
<Label Text="{Binding Start, StringFormat='{0:HH:mm}'}" FontAttributes="Bold" HorizontalTextAlignment="End"/>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</ContentPage>
Central part is this:
<StackLayout Orientation="Horizontal" Padding="10" HorizontalOptions="FillAndExpand">
<Label Text="{Binding Name}" FontAttributes="Bold" HorizontalTextAlignment="Start"/>
<Label Text="{Binding Start, StringFormat='{0:HH:mm}'}" FontAttributes="Bold" HorizontalTextAlignment="End"/>
</StackLayout>
Update:
As requested I have a colored the background of the two labels and the stacklayout. It's the same output if I use HorizontalOptions="End" and HorizontalTextAlignment="End" at the same time or each one alone. Also if I remove the HorizontalOptions="FillAndExpand" on the stacklayout, it's still the exact same graphical output. (The orange color was already present)
Maybe you could use a Grid instead of the StackLayout and place each Label in a different Column:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Text="{Binding Name}" FontAttributes="Bold" HorizontalTextAlignment="Start"/>
<Label Grid.Column="1" Text="{Binding Start, StringFormat='{0:HH:mm}'}" FontAttributes="Bold" HorizontalTextAlignment="End"/>
</Grid>
You could also use nested StackLayout
<StackLayout>
<Label />
<Label Text="Gender:" FontAttributes="Bold"/>
<StackLayout Orientation="Horizontal">
<Label HorizontalOptions="Start" Text="First Name: " FontAttributes="Bold"/>
<Entry HorizontalOptions="EndAndExpand" Placeholder="First Name" MaxLength="256" Text="{Binding FirstName}"></Entry>
</StackLayout>
</StackLayout>
I have a page that contains a listview and Search bar control. There is a custom listview for android. My code as following:
<ContentPage.Content>
<ContentView>
<OnPlatform x:TypeArguments="View">
<OnPlatform.iOS>
<StackLayout Spacing="0">
<SearchBar x:Name="IosSearch"
Placeholder="Search"
TextChanged="IosSearchBar_OnTextChanged"
SearchButtonPressed="OnSearch" BackgroundColor="#19588F">
</SearchBar>
<ListView x:Name="EmpListViewIos"
ItemsSource="{Binding EmpModel.GroupedItems}"
ItemSelected="OnItemSelected"
SeparatorVisibility="Default">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Padding="8">
<StackLayout Spacing="4" Orientation="Horizontal">
<Label Text="{Binding FullName}" FontSize="15" TextColor="Gray" LineBreakMode="NoWrap"/>
</StackLayout>
<StackLayout Spacing="4" Orientation="Horizontal">
<Label Text="{Binding Department}" FontSize="Small" TextColor="#F68933" LineBreakMode="WordWrap"/>
</StackLayout>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</OnPlatform.iOS>
<OnPlatform.Android>
<StackLayout x:Name="androidListView">

As the representation of data is different due to that I am required custom listview for android according to it's layout defined. The above code works fine. The only problem is the redundancy, the search bar control is common for all platform but when I put the search bar control above the <ContentView> it doesn't work throws exception. Similarly the ListView is common for ios and windows only there is custom listview for android but I am forced to repeat the code for windows also same as android.
Can anyone suggest a more efficient way to achieve this. How can I apply platform specific condition only for android and common for windows and ios.
You could share the iOS and WinPhone views using a static resource:
<ContentPage>
<ContentPage.ResourceDictionary>
<StackLayout x:Key="iosOrWpView">
...
</StackLayout>
</ContentPage.ResourceDictionary>
<ContentView>
<OnPlatform x:TypeArguments="View" iOS="{StaticResource iosOrWpView}"
WinPhone="{StaticResource iosOrWpView}">
<OnPlatform.Android>
<StackLayout x:Name="androidListView">
...
</StackLayout>
</OnPlatform.Android>
</OnPlatform>
</ContentView>
<ContentPage>
Not really sure how to properly describe my problem using correct wording as I'm new to Xamarin and Xaml.
I have a Frame with several StackLayouts within and I want to slide a specific StackLayout outside the Frame without showing it outside the Frame.
I can currently do this with:
XAML:
<ContentPage
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:controls="clr-namespace:XLabs.Forms.Controls;assembly=XLabs.Forms"
xmlns:mr="clr-namespace:MR.Gestures;assembly=MR.Gestures"
x:Class="iRemote.UI.Maps.LocationFinderMap"
xmlns:map="clr-namespace:iRemote.Location"
Title="Location Finder">
<Frame HasShadow="true" OutlineColor="Color.Black" WidthRequest="700" HeightRequest="300" Padding="3"
BackgroundColor="White">
<mr:StackLayout x:Name="sl_main" Padding="2" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand"
Orientation="Horizontal" WidthRequest="200">
<StackLayout HorizontalOptions="Start" Orientation="Vertical">
<StackLayout HorizontalOptions="FillAndExpand" Orientation="Horizontal">
<Label Text="Parcel #" />
<Entry x:Name="txtParcel" WidthRequest="100" />
<Label HorizontalOptions="FillAndExpand" />
<Button x:Name="btnClose" BackgroundColor="#0786a3" BorderRadius="30" TextColor="White"
Text="Close" HorizontalOptions="End" />
</StackLayout>
<StackLayout HorizontalOptions="FillAndExpand" Orientation="Horizontal">
<Label Text="Meter #" />
<Entry x:Name="txtMeter" WidthRequest="100" />
</StackLayout>
<StackLayout HorizontalOptions="FillAndExpand" Orientation="Horizontal">
<SearchBar x:Name="search" Placeholder="Search" />
</StackLayout>
<StackLayout Padding="2" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
<StackLayout HorizontalOptions="FillAndExpand">
<mr:Image x:Name="img_map" Source="down" HeightRequest="19" WidthRequest="32" />
</StackLayout>
</StackLayout>
</StackLayout>
<StackLayout x:Name="sl_map" Padding="2" HorizontalOptions="FillAndExpand" HeightRequest="5"
VerticalOptions="FillAndExpand" IsVisible="true" WidthRequest="300">
<map:ExtendedMap
BackgroundColor="Blue"
x:Name="MP"
IsShowingUser="true"
MapType="Street" />
</StackLayout>
</mr:StackLayout>
</Frame>
</ContentPage>
Code-Behind:
if (panelShowing)
{
var rect = new Rectangle(this.Width - sl_map.Width, sl_map.Y, sl_map.Width, sl_map.Height);
sl_map.LayoutTo(rect, 250, Easing.CubicIn);
}
else
{
var rect = new Rectangle(this.Width + sl_map.Width - 40, sl_map.Y, sl_map.Width, sl_map.Height);
sl_map.LayoutTo(rect, 200, Easing.CubicOut);
}
However, sl_map simply just shows outside the frame. I want it to not be visible as it crosses the border of the frame. I hope that's clear enough. Again, sorry if I'm not using the correct terminology. I'm a WinForms guy.
