Valid values for android:fontFamily and what they map to?

0 Answers

Available fonts (as of Oreo)

The Material Design Typography page has demos for some of these fonts and suggestions on choosing fonts and styles.

For code sleuths: fonts.xml is the definitive and ever-expanding list of Android fonts.

Using these fonts

Set the android:fontFamily and android:textStyle attributes, e.g.

<!-- Roboto Bold -->
    android:textStyle="bold" />

to the desired values from this table:

Font                     | android:fontFamily          | android:textStyle
Roboto Thin              | sans-serif-thin             |
Roboto Light             | sans-serif-light            |
Roboto Regular           | sans-serif                  |
Roboto Bold              | sans-serif                  | bold
Roboto Medium            | sans-serif-medium           |
Roboto Black             | sans-serif-black            |
Roboto Condensed Light   | sans-serif-condensed-light  |
Roboto Condensed Regular | sans-serif-condensed        |
Roboto Condensed Medium  | sans-serif-condensed-medium |
Roboto Condensed Bold    | sans-serif-condensed        | bold
Noto Serif               | serif                       |
Noto Serif Bold          | serif                       | bold
Droid Sans Mono          | monospace                   |
Cutive Mono              | serif-monospace             |
Coming Soon              | casual                      |
Dancing Script           | cursive                     |
Dancing Script Bold      | cursive                     | bold
Carrois Gothic SC        | sans-serif-smallcaps        |

(Noto Sans is a fallback font; you can't specify it directly)

Note: this table is derived from fonts.xml. Each font's family name and style is listed in fonts.xml, e.g.

<family name="serif-monospace">
    <font weight="400" style="normal">CutiveMono.ttf</font>

serif-monospace is thus the font family, and normal is the style.


Based on the log of fonts.xml and the former system_fonts.xml, you can see when each font was added:

  • Ice Cream Sandwich: Roboto regular, bold, italic, and bold italic
  • Jelly Bean: Roboto light, light italic, condensed, condensed bold, condensed italic, and condensed bold italic
  • Jelly Bean MR1: Roboto thin and thin italic
  • Lollipop:
    • Roboto medium, medium italic, black, and black italic
    • Noto Serif regular, bold, italic, bold italic
    • Cutive Mono
    • Coming Soon
    • Dancing Script
    • Carrois Gothic SC
    • Noto Sans
  • Oreo MR1: Roboto condensed medium

In the answer to this question the user lists values for android:fontFamily and 12 variants (see below). Where do these values come from? The documentation for android:fontFamily does not list this information in any place (I checked here, and here). The strings are listed in the Android styles.xml file in various places, but how do these map back to the Roboto font?

From android 4.1 / 4.2, the following Roboto font families are available:

android:fontFamily="sans-serif"           // roboto regular  
android:fontFamily="sans-serif-light"     // roboto light  
android:fontFamily="sans-serif-condensed" // roboto condensed  
android:fontFamily="sans-serif-thin"      // roboto thin (android 4.2)  
android:fontFamily="sans-serif-medium"    // roboto medium (android 5.0)

in combination with this


12 variants are possible:

  • Regular
  • Italic
  • Bold
  • Bold-italic
  • Light
  • Light-italic
  • Thin
  • Thin-italic
  • Condensed regular
  • Condensed italic
  • Condensed bold
  • Condensed bold-italic

In the styles.xml file in the application I'm working on somebody listed this as the font family, and I'm pretty sure it's wrong:

<item name="android:fontFamily">Roboto-Regular.ttf</item>

I'd like to get the theme for our app set up correctly (which includes using fontFamily correctly) and remove all the redundancy that is in some of the styles that were created before I had a look at the file.
