Well  after seven years you can change whole app textView or what you want easily by using android support libraries 26     E g   Create your font package app src res font and move your font into it     And in your app theme just add it as a fontFamily        lt style name  AppTheme  parent  Theme AppCompat Light DarkActionBar  gt                    lt item name  android fontFamily  gt  font demo lt  item gt   lt  style gt    Example for use with textView only    lt style name  fontTextView  parent   android style Widget TextView  gt       lt item name  android fontFamily  gt monospace lt  item gt   lt  style gt    And add into your main theme    lt item name  android textViewStyle  gt  style fontTextView lt  item gt    Currently it s worked on 8 1 until 4 1 API Jelly Bean And that s a wide range

Since I was not satisfied with all the presented solutions on SO  I ve come up with mine  It s based on a little trick with tags  i e  you can t use tags in your code   I put the font path there  So when defining views  you can do either this    lt TextView         android id    id textViewHello1          android layout width  wrap content          android layout height  wrap content          android text  Hello World 1          android tag  fonts Oswald-Regular ttf   gt    or this    lt TextView         android id    id textViewHello2          android layout width  wrap content          android layout height  wrap content          android text  Hello World 2          style   style OswaldTextAppearance   gt    lt style name  OswaldTextAppearance  gt           lt item name  android tag  gt fonts Oswald-Regular ttf lt  item gt           lt item name  android textColor  gt  000000 lt  item gt   lt  style gt    Now you can either explicitly access   setup the view as   TextView textView   TextViewHelper setupTextView this  R id textViewHello1  setText  blah      or just setup everything via   TextViewHelper setupTextViews this   ViewGroup  findViewById R id parentLayout       parentLayout is the root view group  relative layout in my case    And what is the magic class you ask  Mostly glued from another SO posts  with helper methods for both activity and fragments   import android app Activity  import android content Context  import android graphics Typeface  import android view View  import android view ViewGroup  import android widget TextView   import java util HashMap  import java util Map   public class TextViewHelper       private static final Map lt String  Typeface gt  mFontCache   new HashMap lt  gt          private static Typeface getTypeface Context context  String fontPath            Typeface typeface          if  mFontCache containsKey fontPath                 typeface   mFontCache get fontPath             else               typeface   Typeface createFromAsset context getAssets    fontPath               mFontCache put fontPath  typeface                     return typeface             public static void setupTextViews Context context  ViewGroup parent            for  int i   parent getChildCount   - 1  i  gt   0  i--                final View child   parent getChildAt i               if  child instanceof ViewGroup                    setupTextViews context   ViewGroup  child                 else                   if  child    null                        TextViewHelper setupTextView context  child                                                        public static void setupTextView Context context  View view            if  view instanceof TextView                if  view getTag      null     also inherited from TextView s style                               TextView textView    TextView  view                  String fontPath    String  textView getTag                    Typeface typeface   getTypeface context  fontPath                   if  typeface    null                        textView setTypeface typeface                                                        public static TextView setupTextView View rootView  int id            TextView textView    TextView  rootView findViewById id           setupTextView rootView getContext   getApplicationContext    textView           return textView             public static TextView setupTextView Activity activity  int id            TextView textView    TextView  activity findViewById id           setupTextView activity getApplicationContext    textView           return textView

Unfortunately there is no good solution for this   I ve seen the many articles about using a custom TextView but what they forget it that it s not only textviews that can implement fonts  amp  there are textviews hidden away in other views inaccessible to the developer  I m not even going to get started on Spannable   You could use an external font utility like   Calligraphy Font Tool  BUT This loops over every view in the application on it s creation and even this utility misses some views  ViewPager renders normal font  then you have the problem that is when Google updates their build tools this will occasionally crash because it needs to target deprecated properties  It s also a little slow as it uses Java s Reflection   It s really up to Google to fix this  We need better font support in Android  If you look at the solution from iOS they literally have 100 s of fonts built in to select from  Want a custom font  Simply drop a TFF in and it s usable    For now were now limited to the offering that Google offers us which is extremely limited but fortunately mobile optimized

Yes  downloadable fonts are so easy  as Dipali s said   This is how you do it      Place a TextView  In the properties pane  select the fontFamily dropdown  If it isn t there  find the caret thingy  the   and click on it to expand textAppearance  under the  Expand the font-family drop down  In the little list  scroll all the way down till you see more fonts This will open up a dialog box where you can search from Google Fonts Search for the font you like with the search bar at the top Select your font  Select the style of the font you like  i e  bold  normal  italic  etc  In the right pane  choose the radio button that says Add font to project Click okay  Now your TextView has the font you like    BONUS  If you would like to style EVERYTHING with text in your application with chosen font  just add  lt item name  android fontfamily  gt  font fontnamehere lt  item gt  into your styles xml

After trying most of the solutions described in this thread  I accidentally found Calligraphy  https   github com chrisjenx Calligraphy  - a library by Christopher Jenkins that lets you easily add custom fonts to your app  The advantages of his lib comparing to approaches suggested here are    you don t have to introduce your own overriden TextView component  you use the built-in TextView   you can easily include the library using gradle   The library doesn t limit your choice of fonts  you just add your preferred ones to the assets dir you not only get custom text views     all the other text-based Android compontents will also be displayed using your custom font

With Android 8 0 using Custom Fonts in Application became easy with downloadable fonts  We can add fonts directly to the res font  folder in the project folder  and in doing so  the fonts become automatically available in Android Studio     Now set fontFamily attribute to list of fonts or click on more and select font of your choice  This will add tools fontFamily   font your font file  line to your TextView   This will Automatically generate few files   1  In values folder it will create fonts certs xml   2  In Manifest it will add this lines      lt meta-data             android name  preloaded fonts              android resource   array preloaded fonts    gt     3  preloaded fonts xml   lt resources gt       lt array name  preloaded fonts  translatable  false  gt           lt item gt  font open sans regular lt  item gt           lt item gt  font open sans semibold lt  item gt       lt  array gt   lt  resources gt

The best way to do it From Android O preview release is this way     It works only if you have android studio-2 4 or above     Right-click the res folder and go to New   Android resource directory  The New Resource Directory window appears  In the Resource type list  select font  and then click OK  Add your font files in the font folder The folder structure below generates R font dancing script  R font la la  and R font ba ba  Double-click a font file to preview the file s fonts in the editor    Next we must create a 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  Enclose each font file  style  and weight attribute in the font tag element  The following XML illustrates adding font-related attributes in the font resource XML                   Adding fonts to a TextView       lt TextView     android layout width  wrap content      android layout height  wrap content      android fontFamily   font hey fontfamily   gt    As from the documentation      Working With Fonts   All the steps are correct

Provided that you placed the font in the right place and there is no error in the font file itself  your code should work like that  RATTLESNAKE   However  it would be a lot easier if you could just define a font in your layout xml  like this    lt LinearLayout xmlns android  http   schemas android com apk res android      xmlns tools  http   schemas android com tools      xmlns app  http   schemas android com apk res-auto      android orientation  vertical      android layout width  match parent      android layout height  match parent      tools context   MainActivity   gt        lt  -- This text view is styled with the app theme -- gt       lt com innovattic font FontTextView         android layout width  wrap content          android layout height  wrap content          android text  This uses my font in bold italic style    gt        lt  -- This text view is styled here and overrides the app theme -- gt       lt com innovattic font FontTextView         android layout width  wrap content          android layout height  wrap content          app flFont  anotherFont          android textStyle  normal          android text  This uses another font in normal style    gt        lt  -- This text view is styled with a style and overrides the app theme -- gt       lt com innovattic font FontTextView         style   style StylishFont          android layout width  wrap content          android layout height  wrap content          android text  This also uses another font in normal style    gt    lt  LinearLayout gt    With the accompanying res values styles xml    lt  xml version  1 0  encoding  utf-8   gt   lt resources xmlns android  http   schemas android com apk res android  xmlns tools  http   schemas android com tools  gt        lt  -- Application theme -- gt       lt  -- Use a different parent if you don t want Holo Light -- gt       lt style name  AppTheme  parent  android Theme Holo Light DarkActionBar  gt           lt item name  android textViewStyle  gt  style MyTextViewStyle lt  item gt       lt  style gt        lt  -- Style to use for ALL text views  including FontTextView  -- gt       lt  -- Use a different parent if you don t want Holo Light -- gt       lt style name  MyTextViewStyle  parent   android style Widget Holo Light TextView  gt           lt item name  android textAppearance  gt  style MyTextAppearance lt  item gt       lt  style gt        lt  -- Text appearance to use for ALL text views  including FontTextView  -- gt       lt  -- Use a different parent if you don t want Holo Light -- gt       lt style name  MyTextAppearance  parent   android style TextAppearance Holo  gt           lt  -- Alternatively  reference this font with the name  aspergit  -- gt           lt  -- Note that only our own TextView s will use the font attribute -- gt           lt item name  flFont  gt someFont lt  item gt           lt item name  android textStyle  gt bold italic lt  item gt       lt  style gt        lt  -- Alternative style  maybe for some other widget -- gt       lt style name  StylishFont  gt           lt item name  flFont  gt anotherFont lt  item gt           lt item name  android textStyle  gt normal lt  item gt       lt  style gt    lt  resources gt    I created a couple of tools specifically for this purpose  Refer to this project from GitHub  or take a look at this blog post which explains the whole thing

On Mobiletuts  there is very good tutorial on Text formatting for Android  Quick Tip  Customize Android Fonts  EDIT  Tested it myself now  Here is the solution  You can use a subfolder called fonts but it must go in the assets folder not the res folder  So     assets fonts   Also make sure that the font ending I mean the ending of the font file itself is all lower case  In other words it should not be myFont TTF but myfont ttf this way must be in lower case
