Adding fonts to style

Open the styles.xml , and set the fontFamily attribute to the font file you want to access.

Using fonts programmatically

To retrieve fonts programmatically, call the getFont(int) method and provide the resource identifier of the font you want to retrieve. This method returns a Typeface object. Although the system picks the best style for you from the fonts information, you can use the setTypeface(android.graphics.Typeface, int) method to set the typeface with specific styles.

Note: The TextView already does this for you.

Kotlin

Using the support library

The Support Library 26.0 provides support to the Fonts in XML feature on devices running Android 4.1 (API level 16) and higher.

Note: When you declare font families in XML layout through the support library, use the app namespace to ensure your fonts load.

To retrieve fonts programmatically, call the ResourceCompat.getFont(Context, int) method and provide an instance of Context and the resource identifier.

Using Custom and Downloadable Fonts in Android

At the Google I/O 2017, Android O or simple Android Oreo was launched and it came with a lot of cool features. One of the really interesting features for developers was the new way to apply fonts right in your XML files. Yeah, you heard it right. Now there is no need of writing some piece of code for using the fonts. Also, you can choose from any of the thousands of fonts on Google Fonts and use them in your app.

So, in this blog, you will understand how to use Custom and Downloadable Fonts in Android?

The Older way of using Fonts

Before we move forward to look for the new or the latest way of using the font, let’s revise the older way of using fonts. Before the release of Android O, fonts can be used in the following 2 ways :

• Using Typeface: One would typically need a custom view that extends the equivalent view were trying to apply a font to. In the custom view, one would create a Typeface and then call setTypeface (or a similar method, that, sets the typeface). One would also need to have the font file placed in the assets folder. The code in the custom view typically looks like:

• Calligraphy Library : You can use some existing libraries for various fonts used in Android. One of them is Calligraphy Library.

Using Custom Font in Android

To work with Custom Font, you need to install the latest version of Android Studio 3.x. This is important as some of the features are not supported on Android Studio 2.x — for example, the font resource directory. Once you are done with the installation of the latest version of Android Studio, create a project and add a text view in any of the activity(This is the text view on which we are going to apply custom font). Then follow the below steps :

• Add a font directory to your project: In the Android View, right click on the resfolder and go to New -> Android Resource Directory. Type fontas the name of the font and select fontas the resource type. Then click on Ok.
• Add the downloaded font to the font directory: Copy and Paste your font into res/font.I am using Pacifico font. You can get this font from FontSqirrel.
• Create a font-family XML file: You can create font families which contain a set of font files with their style and weight details. To create a new font family you need to create a new XML font resource. The benefit is that you can access it as a single unit instead of referencing individual font files for each style and weight. To create a font-family, right click on res/fontand choose New -> Font Resource File and give any name. In my case, I am using my_custom_font.xml.

Note: A really important thing to note is that we had to define attributes using both android and app namespaces. The app namespace is what ensures that the feature is backward compatible.

• Set the font in the XML: Now you can use the font-familyattribute to set the font in XML.

Below is the preview of the above code :

Downloadable Fonts

Now that we have seen how custom fonts work, let’s jump onto another novality — downloadable font . Android 8.0 (API level 26) and Android Support Library 26 introduce support for APIs to request fonts from a provider application instead of bundling files into APK or letting the APK download fonts. A font provider application retrieves fonts and caches them locally so that other apps can request and share fonts. How cool is that!

The feature is available on devices running Android API version 14 and higher through the Support Library 26.

Picture courtesy : Android Developer website

As you can see in the image above, apps using Downloadable Fonts make a FontRequest using the FontsContract API which retrieves the Typeface from the Font Provider. The Font Provider does not need to download fonts if it already exists in the Font Cache.

Benefits of downloadable fonts :

• Reduces the APK size
• Increase the app installation success rate
• Improves the overall system health as multiple APKs can share the same font through a provider. This saves users cellular data, phone memory, and disk space. In this model, the font is fetched over the network when needed.

In order to use the downloadable font in android studio, follow the below steps :

• If you want to use Android Studio to generate the required files, then you’ll need version 3.0+. Add the following (version 26+) to your module’s build.gradle:

• Select a text view in your app that you want to apply the font to and click on the fontFamily attribute under Attributes in the graphical layout

Select the “More Fonts…” at the bottom, which will open the dialog below.

• Make sure to have “ Create downloadable font” selected. This results in three files being downloaded — lato.xml, font_certs.xml and preloaded_fonts.xml.

This file contains the font attributes for loading a Typeface from the Google Fonts Provider Application.

The system uses these certificates to verify the font provider’s identity, to avoid getting fonts from an unknown source. If using the steps above, Android Studio should have automatically generated the string certificates for dev and prod in font_certs.xml below.

preloaded-fonts.xml
This file is referenced in the Android manifest which helps the framework pre-load fonts to avoid delays when the app is launched.

• Make sure this line is added to your app’s Manifest file, Android Studio should have done this automatically:

• Great, now you are ready to apply the fonts in XML!

All I had to do was set the font family in the app’s theme to get TextViews throughout the app to change to Lato, including parts that were bold or italicized. However, if you want to configure the weights, you can follow the same steps to get Lato Bold using Android Studio, and change the weight manually in lato_bold.xml that you can then apply in XML layouts:

That’s all about the custom and downloadable fonts in android. Hope you like the blog.

How to use custom font in a project written in Android Studio

I was trying to use custom font in Android Studio as we did in Eclipse. But unfortunately could not figure out where to put the ‘assets’ folder!

21 Answers 21

Update 2021:

Create a folder named font inside the res folder and copy your font

All font names must be only: lowercase a-z, 0-9, or underscore.

For programmatic use:

For Android Studio 4.2+ there’s even now a menu option:

Select File>New>Folder>Assets Folder

Click finish

Right click on assets and create a folder called fonts

Put your font file in assets > fonts

Use code below to change your textView’s font

There are many ways to set custom font family on field and I am using like that below.

To add fonts as resources, perform the following steps in the Android Studio:

1) Right-click the res folder and go to New > Android resource directory. The New Resource Directory window appears.

2) In the Resource type list, select font, and then click OK.

Note: The name of the resource directory must be font.

3) Add your font files in the font folder.

Add font in desired view in your xml file:

Note: But you required the following things for that:

Android Studio above to 3.0 canary.

Your Activity extends AppCompatActivity.

Update your Gradle file like that:

buildtoolsVersion above to 26 and minimum targetSdkVersion required 26

1. Add dependencies in build.gradle file:

1. gradle-wrapper.properties:

I think instead of downloading .ttf file we can use Google fonts. It’s very easy to implements. only you have to follow these steps. step 1) Open layout.xml of your project and the select font family of text view in attributes (for reference screen shot is attached)

step 2) The in font family select More fonts.. option if your font is not there. then you will see a new window will open, there you can type your required font & select the desired font from that list i.e) Regular, Bold, Italic etc.. as shown in below image.

step 3) Then you will observe a font folder will be auto generated in /res folder having your selected fonts xml file.

Then you can directly use this font family in xml as

or pro grammatically you can achieve this by using
