Default Emojis are working fine in my Xamarin.Forms app and it's colorful. When I add Twitter color fonts its become B/W (black-white). This Procedure I followed.
Initialization
[assembly: ExportFont( "TwitterColorEmoji.ttf", Alias = "TwitterColorEmoji" )]
Here is the example code in xaml
<!-- This is not working -->
<Label x:Name="emojilbl" Text="\U+1F1E9" Margin="20,0,0,0"></Label>
<Label
x:Name="emoji2lbl"
Text="🇦🇨"
Margin="20,0,0,0"
TextColor="#5EE514"
FontSize="40"
FontFamily="TwitterColorEmoji"></Label>
<!-- This is not working -->
<Image BackgroundColor="Black">
<Image.Source>
<FontImageSource
FontFamily="TwitterColorEmoji"
Glyph="🇦🇨"
Size="40"
>
</FontImageSource>
</Image.Source>
</Image>
<!-- This is working fine with default font -->
<Label Text="🇦🇨" Margin="20,0,0,0" FontSize="40"/>
Why emoji is not showing its own color.
Thank for the help in advanced.
Solved issue by changing "Embedded resource" to "Resource" option.

I'm trying to accomplish something similar to the image below where in compact mode you have the icon and the text displayed under it.
I'm not that familiar with modifying the underlying template for the NavigationView to make this work. Can you give me an advice on how to do this?
The code for the NavigationView is pretty much the default one:
<winui:NavigationView
x:Name="navigationView"
Background="{ThemeResource SystemControlBackgroundAltHighBrush}"
IsBackButtonVisible="Collapsed"
IsBackEnabled="False"
IsPaneToggleButtonVisible="False"
IsSettingsVisible="False"
PaneDisplayMode="LeftCompact"
SelectedItem="{x:Bind ViewModel.Selected, Mode=OneWay}">
<winui:NavigationView.MenuItems>
<winui:NavigationViewItem x:Uid="Shell_Main" helpers:NavHelper.NavigateTo="views:MainPage">
<winui:NavigationViewItem.Icon>
<FontIcon Glyph="" />
</winui:NavigationViewItem.Icon>
</winui:NavigationViewItem>
<winui:NavigationViewItem x:Uid="Shell_WorkOrders" helpers:NavHelper.NavigateTo="views:WorkOrdersPage">
<winui:NavigationViewItem.Icon>
<FontIcon Glyph="" />
</winui:NavigationViewItem.Icon>
</winui:NavigationViewItem>
<winui:NavigationViewItem x:Uid="Shell_Materials" helpers:NavHelper.NavigateTo="views:MaterialsPage">
<winui:NavigationViewItem.Icon>
<FontIcon Glyph="" />
</winui:NavigationViewItem.Icon>
</winui:NavigationViewItem>
<winui:NavigationViewItem x:Uid="Shell_Documentation" helpers:NavHelper.NavigateTo="views:DocumentationPage">
<winui:NavigationViewItem.Icon>
<FontIcon Glyph="" />
</winui:NavigationViewItem.Icon>
</winui:NavigationViewItem>
</winui:NavigationView.MenuItems>
<i:Interaction.Behaviors>
<ic:EventTriggerBehavior EventName="ItemInvoked">
<ic:InvokeCommandAction Command="{x:Bind ViewModel.ItemInvokedCommand}" />
</ic:EventTriggerBehavior>
</i:Interaction.Behaviors>
<Grid>
<Frame x:Name="shellFrame" />
</Grid>
</winui:NavigationView>
NavigationView icons + text in compact mode
it's hard to make interface like the screenshot that you mentioned above, you need to edit the default NavigationViewItemPresenter style, and set icon above and content bottom.
For making navigation like above, we suggest you custom side navigation with SplitView to replace default NavigationView. and set ListView as pane content. Then you could design the nav item flexibly by customizing ItemTemplate .
For more detail please refer to Xaml-Controls-Gallery here.
I have a simple (Android) application in Xamarin.
Until now, it uses a single language, now I add a translation for a second language. I use resource .resx files and I use it in XAML like this:
<Span Text="{x:Static resource:AppResources.Text1}" />
where Text1 is loaded from a resource file (depend on language).
I don't know how to do a similar thing in the next line, where I use Binding and StringFormat:
<Label Text="{Binding Datum, StringFormat='Some text: {0}'}" />
I tried with:
<Label Text="{Binding Datum, StringFormat='{x:Static resource:AppResources.Text2} {0}'}" />
but it didn't work.
Any idea?
use Spans to combine data and text
<Label>
<Label.FormattedText>
<FormattedString>
<Span Text="{x:Static resource:AppResources.Text1}" />
<Span Text="{Binding Datum}" />
</FormattedString>
</Label.FormattedText>
</Label>
Font awesome icons are not working for me in Xamarin.Forms. This is my Label xaml
<Label TextColor="Red" FontFamily="FontAwesomeBrands" FontSize="Large" Text=""
RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent,
Property=Width,Factor=1}">
</Label>
I have added these file in Assests folder of android project
Output just showing empty symbol. how can I make it work?
Have you created platform-specific CustomRenderers for that?
Please, look at my answer, and follow the tutorial. Link to answer
Hope this helps!
I use Xam.FormsPlugin.Iconize and Xam.Plugin.Iconize NuGet packages for icons:
xmlns:iconize="clr-namespace:FormsPlugin.Iconize;assembly=FormsPlugin.Iconize"
<iconize:IconLabel Text="fa-question-circle" FontSize="Medium" TextColor="#666666" HorizontalTextAlignment="End"/>
I'm using Font Awesome 5 in my xamarin app. I would like to show an icon in a RadButton (Telerik):
<telerikInput:RadButton
Grid.Row="0" Grid.Column="0"
Text=""
FontSize="30"
Style="{StaticResource TelerikButtonStyle}"
Command="{Binding MyCommand}">
<telerikInput:RadButton.FontFamily>
<OnPlatform x:TypeArguments="x:String">
<On Platform="Android" Value="FontAwesome5Free-Solid-900.otf#Font Awesome 5 Free Solid" />
<On Platform="Windows" Value="Assets/Fonts/FontAwesome5Free-Solid-900.otf#Font Awesome 5 Free Solid" />
</OnPlatform>
</telerikInput:RadButton.FontFamily>
</telerikInput:RadButton>`
For Android, this works fine, but in UWP it shows a blank box.
On Platform should be using "UWP" instead of the ""Windows""
<On Platform="UWP" Value="Assets/Fonts/FontAwesome5Free-Solid-900.otf#Font Awesome 5 Free Solid" />
Font Awesome does not contain Solid in the Font Name. Try removing Solid from the name as below:
<On Platform="Windows" Value="Assets/Fonts/FontAwesome5Free-Solid-900.otf#Font Awesome 5 Free" />
EDIT:
If you are using Xamarin.Forms 2.3.4 or greater than replace Windows with UWP as below:
<On Platform="UWP" Value="Assets/Fonts/FontAwesome5Free-Solid-900.otf#Font Awesome 5 Free" />
I have tried this in blank solution and got it working as follows:
Added the font in the Assets/Fonts folder in UWP project and made sure it has the correct name (in my case I renamed the font to FontAwesome5.otf) and Build Action of Content:
Used the following to reference the font (note - this sample only sets UWP path, so you should add the other platforms as in your question):
XAML:
<Label Text=""
FontSize="40"
HorizontalOptions="Center"
VerticalOptions="CenterAndExpand">
<Label.FontFamily>
<OnPlatform x:TypeArguments="x:String">
<On Platform="UWP" Value="Assets/Fonts/FontAwesome5.otf#Font Awesome 5 Free" />
</OnPlatform>
</Label.FontFamily>
</Label>
The proper # suffix can be found out using some font viewer apps, like dp4 Font Viewer:

Hi I am new to Xamarin Forms and am from native iOS development.
For showing alerts / action sheets I am using this https://github.com/aritchie/userdialogs.
For implementing this I followed this How to use Acr.UserDialogs.
I am getting alert successfully by following this, but now I need to customise the OK / Cancel Button's background color, alignment, frame values, hide and show the buttons..
Thanks in advance.
I need to customise the OK / Cancel Button's background color, alignment, frame values, hide and show the buttons.
As the author said, you could do this by creating a style and apply it in AlertConfig.
For example:
In the style.xml:
<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
<!-- Used for the buttons -->
<item name="colorAccent">#AAAAAA</item>
<!-- Used for the title and text -->
<item name="android:textColorPrimary">#FFFFFF</item>
<!-- Used for the background -->
<item name="android:background">#DDDDDD</item>
<!-- Used for the Alignment -->
<item name="android:gravity">center_horizontal</item>
</style>
And you could find this style Id in the Resource.Designer.cs.
// aapt resource value: 0x7f0b0189
public const int AlertDialogCustom = 2131427721;
Then in the code create a AlertConfig to config the alertdialog:
AlertConfig alertConfig = new AlertConfig();
alertConfig.OkText = "OKOK";
alertConfig.Message = "Message";
alertConfig.Title = "Title";
alertConfig.AndroidStyleId=2131427721;
UserDialogs.Instance.Alert(alertConfig);
With Rg.Plugins.Popup Nuget you can customize the popup.
Finally I am not using any nugget packages. Now I created my own CustomAlert class. I hope it will helpful for any one.
#Miguel Angel please look at below code
In my CustomAlert.xaml file
<?xml version="1.0" encoding="UTF-8"?>
<ContentView xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="wwww/2009/xaml" x:Class="MY.UserControls.CustomAlert">
<Grid RowSpacing="0" ColumnSpacing="0">
<Grid BackgroundColor="#656565" Opacity="0.5">
</Grid>
<StackLayout BackgroundColor="{StaticResource WhiteColor}" VerticalOptions="Center" Margin="10" Padding="10" >
<Label Text="Title" FontSize="18" HorizontalTextAlignment="Center" Margin="0,0,0,0" TextColor="Black"></Label>
<Label Text="Descrption." FontSize="14"
HorizontalTextAlignment="Start"
Margin="10,10,5,5"
VerticalOptions="Center" TextColor="Gray"></Label>
<Button Text="OK" TextColor="{StaticResource WhiteColor}"
Command="{Binding DismissCustomAlertCommand}"
HorizontalOptions="Center" VerticalOptions="Center"
BackgroundColor="Red" Margin="30,0,30,0" WidthRequest="400" HeightRequest="40"></Button>
</StackLayout>
</Grid>
</ContentView>
Thank you
