Maybe something a bit simpler   public class Fonts     public static HashSet lt String Typeface gt  fonts   new HashSet lt  gt        public static Typeface get Context context  String file        if    fonts contains file           synchronized  this            Typeface typeface   Typeface createFromAsset context getAssets    name           fonts put name  typeface                     return fonts get file             Usage Typeface myFont   Fonts get  arial ttf       Note this code is untested  but in general this approach should work well

Another way to consolidate font creation     public class Font     public static final Font  PROXIMA NOVA      new Font  ProximaNovaRegular otf      public static final Font  FRANKLIN GOTHIC   new Font  FranklinGothicURWBoo ttf      private final String      assetName    private volatile Typeface typeface     private Font String assetName        this assetName   assetName         public void apply Context context  TextView textView        if  typeface    null          synchronized  this            if  typeface    null              typeface   Typeface createFromAsset context getAssets    assetName                               textView setTypeface typeface           And then to use in your activity     myTextView    TextView  findViewById R id myTextView   Font PROXIMA NOVA apply this  myTextView     Mind you  this double-checked locking idiom with the volatile field only works correctly with the memory model used in Java 1 5

First download the  ttf file of the font you need  arial ttf   Place it in the  assets  folder   Inside assets folder create new folder named fonts and place it inside it   Use the following code to apply the font to your TextView   Typeface type   Typeface createFromAsset getAssets    fonts arial ttf     textView setTypeface type

Best practice is to use Android Support Library version 26 0 0 or above   STEP 1  add font file   In res folder create new font resource dictionary Add font file   ttf   orf    For example  when font file will be helvetica neue ttf that will generates R font helvetica neue  STEP 2  create font family   In font folder add new resource file Enclose each font file  style  and weight attribute in the  element    For example    lt  xml version  1 0  encoding  utf-8   gt   lt font-family xmlns android  http   schemas android com apk res android  gt         lt font             android fontStyle  normal              android fontWeight  400              android font   font helvetica neue    gt   lt  font-family gt    STEP 3  use it  In xml layouts    lt TextView     android layout width  wrap content      android layout height  wrap content      android fontFamily   font my font   gt    Or add fonts to style    lt style name  customfontstyle  parent   android style TextAppearance Small  gt       lt item name  android fontFamily  gt  font lobster lt  item gt   lt  style gt    For more examples you can follow documentation      Working with fonts

You might want to create static class which will contain all the fonts  That way  you won t create the font multiple times which might impact badly on performance  Just make sure that you create a sub-folder called  fonts  under  assets  folder   Do something like   public class CustomFontsLoader    public static final int FONT NAME 1     0  public static final int FONT NAME 2     1  public static final int FONT NAME 3     2   private static final int NUM OF CUSTOM FONTS   3   private static boolean fontsLoaded   false   private static Typeface   fonts   new Typeface 3    private static String   fontPath          fonts FONT NAME 1 ttf        fonts FONT NAME 2 ttf        fonts FONT NAME 3 ttf              Returns a loaded custom font based on it s identifier           param context - the current context     param fontIdentifier   the identifier of the requested font         return Typeface object of the requested font      public static Typeface getTypeface Context context  int fontIdentifier        if   fontsLoaded            loadFonts context             return fonts fontIdentifier       private static void loadFonts Context context        for  int i   0  i  lt  NUM OF CUSTOM FONTS  i              fonts i    Typeface createFromAsset context getAssets    fontPath i              fontsLoaded   true         This way  you can get the font from everywhere in your application

First  the default is not Arial  The default is Droid Sans   Second  to change to a different built-in font  use android typeface in layout XML or setTypeface   in Java   Third  there is no Helvetica font in Android  The built-in choices are Droid Sans  sans   Droid Sans Mono  monospace   and Droid Serif  serif   While you can bundle your own fonts with your application and use them via setTypeface    bear in mind that font files are big and  in some cases  require licensing agreements  e g   Helvetica  a Linotype font    EDIT     The Android design language relies on traditional typographic tools   such as scale  space  rhythm  and alignment with an underlying grid    Successful deployment of these tools is essential to help users   quickly understand a screen of information  To support such use of   typography  Ice Cream Sandwich introduced a new type family named   Roboto  created specifically for the requirements of UI and   high-resolution screens       The current TextView framework offers Roboto in thin  light  regular   and bold weights  along with an italic style for each weight  The   framework also offers the Roboto Condensed variant in regular and bold   weights  along with an italic style for each weight    After ICS  android includes Roboto fonts style  Read more Roboto  EDIT 2     With the advent of Support Library 26  Android now supports custom fonts by    default  You can insert new fonts in res fonts which can be set to TextViews individually either in XML or programmatically  The default font for the whole application can also be changed by defining it styles xml The android developer documentation has a clear guide on this here

I finally got a very easy solution to this    use these Support libraries in app level gradle   compile  com android support appcompat-v7 26 0 2  compile  com android support support-v4 26 0 2   then create a directory named  font  inside the res folder put fonts ttf  files in that font directory  keep in mind the naming conventions  e g name should not contain any special character  any uppercase character and any space or tab  After that  reference that font from xml like this            lt Button         android id    id btn choose employee          android layout width  140dp          android layout height  40dp          android layout centerInParent  true          android background   drawable rounded red btn          android onClick  btnEmployeeClickedAction          android text   string searching jobs          android textAllCaps  false          android textColor   color white          android fontFamily   font times new roman test            gt     In this example  times new roman test is a font ttf file from that font directory
