As per the documentation

Android 8.0 (API level 26) introduces a new feature, Fonts in XML, which lets you use fonts as resources. You can add the font file in the res/font/ folder to bundle fonts as resources. These fonts are compiled in your R file and are automatically available in Android Studio. You can access the font resources with the help of a new resource type, font. For example, to access a font resource, use @font/myfont, or R.font.myfont. To use the Fonts in XML feature on devices running Android API version 14 and higher, use the Support Library 26.

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.

Creating a font family

A font family is a set of font files along with its style and weight details. In Android, you can create a new font family as an XML resource and access it as a single unit, instead of referencing each style and weight as separate resources. By doing this, the system can select the correct font based on the text style you are trying to use.

To create a font family, perform the following steps in the Android Studio:

1.Right-click the font folder and go to New > Font resource file. The New Resource File window appears.

2.Enter the file name, and then click OK. The new font resource XML opens in the editor.

3.Enclose each font file, style, and weight attribute in the element. The following XML illustrates adding font-related attributes in the font resource XML:

Using fonts in XML layouts

In the layout XML file, set the fontFamily attribute to the font file you want to access.

Open the Properties window to set the font for the TextView. Select a view to open the Properties window. Note: The Properties window is available only when the design editor is open. Select the Design tab at the bottom of the window.

Expand the textAppearance property, and then select the font from the fontFamily list.

Adding fonts to style

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