How to use Font Awesome icons in Xamarin.Forms Accordion (SfAccordion)?
You can use FontAwesome icons in Xamarin.Forms Accordion. Please follow the steps below to work with FontAwesome icons,
STEP 1: Download the font icons on FontAwesome.com. You can also refer to the document here.
STEP 2: Place the ttf/otf file in the shared code project and set the Build action as follows,
Project | Location | Build action |
|---|---|---|
Android | Assets | AndroidAsset |
iOS | Resources | BundleResource |
UWP | Assets | Content |
In addition, add the name of the font file to the info.plist file of iOS project.
<key>UIAppFonts</key> <array> <string>ExpanderIcons.ttf</string> </array>
To use custom fonts in Xamarin.Forms, refer to the document here.
STEP 3: Define the font as StaticResource, in the ResourceDictionary.
<ContentPage.Resources> <ResourceDictionary> <OnPlatform x:TypeArguments="x:String" x:Key="FontAwesome"> <On Platform="Android" Value="FontAwesomeRegular.otf#Regular" /> <On Platform="iOS" Value="FontAwesome5Free-Regular" /> <On Platform="UWP" Value="/Assets/FontAwesomeRegular.otf#Font Awesome 5 Free" /> </OnPlatform> </ResourceDictionary> </ContentPage.Resources>
STEP 4: Bind the FontFamily to the FontImageSource of Button.ImageSource using resource key. Also, bind the icon value to the Glyph property. You can also use Button.Command to update the icon at run time.
<accordion:SfAccordion x:Name="accordion" BindableLayout.ItemsSource="{Binding Info}" ExpandMode="SingleOrNone" HeaderIconPosition="Start">
<BindableLayout.ItemTemplate>
<DataTemplate>
<accordion:AccordionItem >
<accordion:AccordionItem.Header>
<Grid>
<Label TextColor="#495F6E" Text="{Binding Name}" VerticalOptions="Center" HorizontalOptions="StartAndExpand" HeightRequest="50" VerticalTextAlignment="Center"/>
<Button Grid.Column="1" HeightRequest="50" WidthRequest="50" Command="{Binding Path=BindingContext.FavouriteCommand, Source={x:Reference accordion}}" CommandParameter="{Binding .}" HorizontalOptions="EndAndExpand" VerticalOptions="CenterAndExpand" BackgroundColor="Transparent">
<Button.ImageSource>
<FontImageSource Glyph="{Binding FavouriteIcon}" FontFamily="{StaticResource FontAwesome}" Color="#ea2c62" Size="18" />
</Button.ImageSource>
</Button>
</Grid>
</accordion:AccordionItem.Header>
<accordion:AccordionItem.Content>
<Grid BackgroundColor="#e8e8e8" Padding="5,0,0,0">
<Label Text="{Binding Description}" VerticalOptions="Center"/>
</Grid>
</accordion:AccordionItem.Content>
</accordion:AccordionItem>
</DataTemplate>
</BindableLayout.ItemTemplate>
</accordion:SfAccordion>
STEP 5: Change the icon in the Button execution handler.
public class ItemInfoRepository
{
public Command<object> FavouriteCommand { get; set; }
public ItemInfoRepository()
{
FavouriteCommand = new Command<object>(OnFavouriteClicked);
}
private void OnFavouriteClicked(object obj)
{
var item = obj as ItemInfo;
item.FavouriteIcon = item.FavouriteIcon == "\uf005" ? "\uf004" : "\uf005";
}
}
