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 regularandroid:fontFamily="sans-serif-light"     // roboto lightandroid:fontFamily="sans-serif-condensed" // roboto condensedandroid:fontFamily="sans-serif-black"     // roboto blackandroid: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 16 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-Black
• Roboto-Black italic
• Roboto-Medium
• Roboto-Medium italic

fonts.xml

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="font_family_light">sans-serif-light</string>    <string name="font_family_medium">sans-serif-medium</string>    <string name="font_family_regular">sans-serif</string>    <string name="font_family_condensed">sans-serif-condensed</string>    <string name="font_family_black">sans-serif-black</string>    <string name="font_family_thin">sans-serif-thin</string></resources>

This is the way to set the font programmatically:

TextView tv = (TextView) findViewById(R.id.appname);Typeface face = Typeface.createFromAsset(getAssets(),            "fonts/epimodem.ttf");tv.setTypeface(face);

put the font file in your assets folder. In my case I created a subdirectory called fonts.

EDIT: If you wonder where is your assets folder see this question

Starting from Android-Studio 3.0 its very easy to change font family

Using support library 26, it will work on devices running Android API version 16 and higher

Create a folder font under res directory .Download the font which ever you want and paste it inside font folder. The structure should be some thing like below

Note: As of Android Support Library 26.0, you must declare both sets of attributes ( android: and app: ) to ensure your fonts load on devices running Api 26 or lower.

Now you can change font in layout using

<TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:fontFamily="@font/dancing_script"app:fontFamily="@font/dancing_script"/>

To change Programatically

 Typeface typeface = getResources().getFont(R.font.myfont);   //or to support all versions useTypeface typeface = ResourcesCompat.getFont(context, R.font.myfont); textView.setTypeface(typeface);  

To change font using styles.xml create a style

 <style name="Regular">        <item name="android:fontFamily">@font/dancing_script</item>        <item name="fontFamily">@font/dancing_script</item>        <item name="android:textStyle">normal</item> </style>

and apply this style to TextView

  <TextView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    style="@style/Regular"/>

you can also Create your own font family

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

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

Write your own font family here , for example

<font-family xmlns:android="http://schemas.android.com/apk/res/android">    <font        android:fontStyle="normal"        android:fontWeight="400"        android:font="@font/lobster_regular" />    <font        android:fontStyle="italic"        android:fontWeight="400"        android:font="@font/lobster_italic" /></font-family>

this is simply a mapping of a specific fontStyle and fontWeight to the font resource which will be used to render that specific variant. Valid values for fontStyle are normal or italic; and fontWeight conforms to the CSS font-weight specification

1. To change fontfamily in layout you can write

 <TextView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:fontFamily="@font/lobster"/>

2. To Change Programmatically

 Typeface typeface = getResources().getFont(R.font.lobster);   //or to support all versions useTypeface typeface = ResourcesCompat.getFont(context, R.font.lobster); textView.setTypeface(typeface);  

To change font of entire App Add these two lines in AppTheme

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">     <item name="android:fontFamily">@font/your_font</item>     <item name="fontFamily">@font/your_font</item>  </style>
