We love everything that makes the process of building beautiful applications easier. Using font Icons in Xamarin Forms apps makes this easier. Having to skip the process of creating and adding manually every icon for our application is just awesome. Font Icons are a great tool which we can leverage for this purpose.

Several months ago, I wrote this blog post about adding Font Awesome Icons in your Xamarin Forms applications. Now, here is a simple blog post about using Bootstrap and Material font icons in your Xamarin Forms apps.

Adding Font Icons in Xamarin Forms

The font icons should be added in the platform specific projects. There is a specific way to add font icons for each platform.

On iOS, you need to add the font icons to the Resources folder in the iOS project. Then, edit the info.plist file.

Accessing The Fonts in Your App

To display these fonts in your app, you can add it as a resource and call the resource as font style for a Label.

Bootstrap

After defining the Bootstrap resource, we use it as font style for any label which should contain bootstrap icons.

Material Design

Above we defined a Material Design font style resource. This will be designed a the Font style of every label which serves as icon in your app.

To get bootstrap icons code, you can follow this link. Select the icon you want to add and get its “Unicode HTML Entity”. This code will be added to your XAML preceding the “&#x” characters and ending with “;” character. As follows:

Material Design

To get Material design icon codes, you can navigate to this tool . Browse and upload your font icons file. It will generate the code for each font as used in C#. To use the code generated in XAML, replace the ‘\u’ character with ‘&#x’ and at the end add a ‘;’.
