OLD:

Your best bet would be this:

Customize Android Fonts

So

    TextView text = (TextView) findViewById(R.id.custom_font);     Typeface font = Typeface.createFromAsset(getAssets(), "yourfont.ttf");     text.setTypeface(font); 

With your .ttf in the root of the "assets" folder.

Answer 2

You could do it like this. Create a custom textview and use that one everywhere

public class MyTextView extends android.widget.TextView {      public MyTextView(Context context)     {         this(context, null);     }      public MyTextView(Context context, AttributeSet attrs)     {         this(context, attrs, 0);     }      public MyTextView(Context context, AttributeSet attrs, int defStyle)     {         super(context, attrs);         if (this.isInEditMode()) return ;          final TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.SomeStyle);         final String customFont = a.getString(R.styleable.SomeStyle_font);          //Build a custom typeface-cache here!         this.setTypeface(             Typeface.createFromAsset(context.getAssets(), customFont)         );       } } 

Add this to attrs.xml

<declare-styleable name="SomeStyle">     <attr name="font" format="string" /> </declare-styleable> 

Then in your theme, do this: This will make sure all the textviews will use the style MyTextView

<item name="android:textViewStyle">@style/MyTextView</item> 

And now we can define your custom font using your custom attribute in this style.

<style name="MyTextView" parent="@android:style/Widget.TextView">     <item name="font">MyPathToFontInAssets.ttf</item> </style> 

So whenever you use MyTextView in the project, it will have your custom font.

IMPORTANT: Typefaces are not cached, so if you plan on using this code, you should also build a custom typeface-cache so you can re-use the custom typeface for all textviews. This will significantly speed-up the application!

UPDATE: As Amir was saying, this is almost the same as Custom fonts and XML layouts (Android) but i also use android styling to automatically use it on all textviews in the app.
