How to set a particular font for a button text in android?

Question

I want my button text to be in the Copperplate Gothic Light font and I yet have not come across a simple clean code for a simple function as this. Help!

PS: Since android comes with ariel and a few other fonts on its own we need to import (apologies for the lack of a better word since I'm new to this) the font we wish to use. This is all I have been able to gather till yet and this is where the trail ends for me.

If you plan to add the same font to several buttons I suggest that you go all the way and implement it as a style and subclass button:

public class ButtonPlus extends Button {      public ButtonPlus(Context context) {         super(context);     }      public ButtonPlus(Context context, AttributeSet attrs) {         super(context, attrs);         CustomFontHelper.setCustomFont(this, context, attrs);     }      public ButtonPlus(Context context, AttributeSet attrs, int defStyle) {         super(context, attrs, defStyle);         CustomFontHelper.setCustomFont(this, context, attrs);     } } 

This is a helper class to set a font on a TextView (remember, Button is a subclass of TextView) based on the com.my.package:font attribute:

public class CustomFontHelper {      /**      * Sets a font on a textview based on the custom com.my.package:font attribute      * If the custom font attribute isn't found in the attributes nothing happens      * @param textview      * @param context      * @param attrs      */     public static void setCustomFont(TextView textview, Context context, AttributeSet attrs) {         TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CustomFont);         String font = a.getString(R.styleable.CustomFont_font);         setCustomFont(textview, font, context);         a.recycle();     }      /**      * Sets a font on a textview      * @param textview      * @param font      * @param context      */     public static void setCustomFont(TextView textview, String font, Context context) {         if(font == null) {             return;         }         Typeface tf = FontCache.get(font, context);         if(tf != null) {             textview.setTypeface(tf);         }     }  } 

And here's the FontCache to reduce memory usage on older devices:

public class FontCache {      private static Hashtable<String, Typeface> fontCache = new Hashtable<String, Typeface>();      public static Typeface get(String name, Context context) {         Typeface tf = fontCache.get(name);         if(tf == null) {             try {                 tf = Typeface.createFromAsset(context.getAssets(), name);             }             catch (Exception e) {                 return null;             }             fontCache.put(name, tf);         }         return tf;     } } 

In res/values/attrs.xml we define the custom styleable attribute

<?xml version="1.0" encoding="utf-8"?> <resources>     <declare-styleable name="CustomFont">         <attr name="font" format="string"/>     </declare-styleable> </resources> 

And finally an example use in a layout:

    <com.my.package.buttons.ButtonPlus         style="@style/button"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/button_sometext"/> 

And in res/values/style.xml

<style name="button" parent="@android:style/Widget.Button">     <item name="com.my.package:font">fonts/copperplate_gothic_light.TTF</item> </style> 

This may seem like an awful lot of work, but you'll thank me once you have couple of handfuls of buttons and textfields that you want to change font on.
