According to How to change fontFamily of TextView in Android

From android 4.1 / 4.2 / 5.0, 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

android:textStyle="normal|bold|italic"

this 14 variants are possible:

• Roboto regular
• Roboto italic
• Roboto bold
• Roboto bold italic
• Roboto-Light
• Roboto-Light italic
• Roboto-Thin
• Roboto-Thin italic
• Roboto-Condensed
• Roboto-Condensed italic
• Roboto-Condensed bold
• Roboto-Condensed bold italic
• Roboto-Medium

You can also do this programmatically using code as below:

textView.setTypeface(Typeface.create("sans-serif-thin", Typeface.NORMAL));

Using typeface

Available built-ibn fonts are:

• normal
• sans
• serif
• monospace

You can cobine them like below:

   android:typeface="sans" | "serif" | "monospace"

See android:typeface.

Using styles.xml

You set style in styles.xml` like that:

<style name="boldText">
    <item name="android:textStyle">bold|italic</item>
    <item name="android:textColor">#FFFFFF</item>
</style>

and to use this style in main.xml layout file just use:

style="@style/boldText"

Combining Text atrributes

 android:fontFamily="serif" 
 android:textStyle="italic"
