How to change fontFamily of TextView in Android

Question

So I d like to change the android fontFamily in Android but I don t see any pre-defined fonts in Android  How do I select one of the pre-defined ones  I don t really need to define my own TypeFace but all I need is something different from what it shows right now    lt TextView     android id    id HeaderText      android layout width  wrap content      android layout height  wrap content      android layout alignParentTop  true      android layout centerHorizontal  true      android layout marginTop  52dp      android gravity  center      android text  CallerBlocker      android textSize  40dp      android fontFamily  Arial     gt    It seems what I did up there won t really work  BTW android fontFamily  Arial  was a stupid attempt

Here you can see all the avaliable fontFamily values and it's corresponding font file's names(This file is using in android 5.0+). In mobile device, you can find it in:

/system/etc/fonts.xml (for 5.0+)

(For android 4.4 and below using this version, but I think that fonts.xml has a more clear format and easy to understand.)

For example,

    <!-- first font is default -->
20    <family name="sans-serif">
21        <font weight="100" style="normal">Roboto-Thin.ttf</font>
22        <font weight="100" style="italic">Roboto-ThinItalic.ttf</font>
23        <font weight="300" style="normal">Roboto-Light.ttf</font>
24        <font weight="300" style="italic">Roboto-LightItalic.ttf</font>
25        <font weight="400" style="normal">Roboto-Regular.ttf</font>
26        <font weight="400" style="italic">Roboto-Italic.ttf</font>
27        <font weight="500" style="normal">Roboto-Medium.ttf</font>
28        <font weight="500" style="italic">Roboto-MediumItalic.ttf</font>
29        <font weight="900" style="normal">Roboto-Black.ttf</font>
30        <font weight="900" style="italic">Roboto-BlackItalic.ttf</font>
31        <font weight="700" style="normal">Roboto-Bold.ttf</font>
32        <font weight="700" style="italic">Roboto-BoldItalic.ttf</font>
33    </family>

The name attribute name="sans-serif" of family tag defined the value you can use in android:fontFamily.

The font tag define the corresponded font files.

In this case, you can ignore the source under , it's using for fonts' fallback logic.

You can also do this by adding a font folder under the res directory like below     Then  selecting Font as the resource type    You can find avaliable fonts from https   www 1001fonts com   and then extracting the TTF files to this font directory     Finally  just change the XML file that contains your textview by adding android fontFamily   font urfontfilename

I use Letter Press lib for my NonTextView stuff like Buttons and kianoni fontloader lib for my TextViews cause of usage of style in this lib is more easy than Letter Press for me and i got ideal feedback with that  this is great for those who want to use custom font except Roboto Font  so it was my experience with font libs  for those who want to use custom class for change font i highly recommended to create this class with this snippet      public class TypefaceSpan extends MetricAffectingSpan           An  lt code gt LruCache lt  code gt  for previously loaded typefaces         private static LruCache lt String  Typeface gt  sTypefaceCache               new LruCache lt String  Typeface gt  12        private Typeface mTypeface                  Load the   link android graphics Typeface  and apply to a   link android text Spannable               public TypefaceSpan Context context  String typefaceName            mTypeface   sTypefaceCache get typefaceName            if  mTypeface    null                mTypeface   Typeface createFromAsset context getApplicationContext                        getAssets    String format  fonts  s   typefaceName                    Cache the loaded Typeface             sTypefaceCache put typefaceName  mTypeface                         Override     public void updateMeasureState TextPaint p            p setTypeface mTypeface               Note  This flag is required for proper typeface rendering         p setFlags p getFlags     Paint SUBPIXEL TEXT FLAG               Override     public void updateDrawState TextPaint tp            tp setTypeface mTypeface               Note  This flag is required for proper typeface rendering         tp setFlags tp getFlags     Paint SUBPIXEL TEXT FLAG             And use class like this    AppData   PreferenceManager getDefaultSharedPreferences this   TextView bannertv   TextView  findViewById R id txtBanner       SpannableString s   new SpannableString getResources   getString R string enterkey        s setSpan new TypefaceSpan this  AppData getString  font-Bold  null    0  s length                Spannable SPAN EXCLUSIVE EXCLUSIVE       bannertv setText s     maybe this help

With some trial and error I learned the following   Within the   xml you can combine the stock fonts with the following functions  not only with typeface    android fontFamily  serif    android textStyle  italic    With this two styles  there was no need to use typeface in any other case  The range of combinations is much more bigger with fontfamily amp textStyle

Android doesn t allow you to set custom fonts from the XML layout  Instead  you must bundle the specific font file in your app s assets folder  and set it programmatically  Something like  TextView textView    TextView  findViewById  lt your TextView ID gt    Typeface typeFace   Typeface createFromAsset getAssets     quot  lt file name gt  quot    textView setTypeface typeFace    Note that you can only run this code after setContentView   has been called  Also  only some fonts are supported by Android  and should be in a  ttf  TrueType  or  otf  OpenType  format  Even then  some fonts may not work  This is a font that definitely works on Android  and you can use this to confirm that your code is working in case your font file isn t supported by Android  Android O Update  This is now possible with XML in Android O  based on Roger s comment

The valid value of android fontFamily is defined in  system etc system fonts xml 4 x  or  system etc fonts xml 5 x   But Device Manufacturer might modify it  so the actual font used by setting fontFamily value depends on the above-mentioned file of the specified device   In AOSP  the Arial font is valid but must be defined using  arial  not  Arial   for example android fontFamily  arial   Have a qucik look at Kitkat s system fonts xml       lt family gt       lt nameset gt           lt name gt sans-serif lt  name gt           lt name gt arial lt  name gt           lt name gt helvetica lt  name gt           lt name gt tahoma lt  name gt           lt name gt verdana lt  name gt       lt  nameset gt       lt fileset gt           lt file gt Roboto-Regular ttf lt  file gt           lt file gt Roboto-Bold ttf lt  file gt           lt file gt Roboto-Italic ttf lt  file gt           lt file gt Roboto-BoldItalic ttf lt  file gt       lt  fileset gt   lt  family gt                                                                                There are three relevant xml-attributes for defining a  font  in layout--android fontFamily  android typeface and android textStyle  The combination of  fontFamily  and  textStyle  or  typeface  and  textStyle  can be used to change the appearance of font in text  so does used alone  Code snippet in TextView java like this       private void setTypefaceFromAttrs String familyName  int typefaceIndex  int styleIndex        Typeface tf   null      if  familyName    null            tf   Typeface create familyName  styleIndex           if  tf    null                setTypeface tf               return                      switch  typefaceIndex            case SANS              tf   Typeface SANS SERIF              break           case SERIF              tf   Typeface SERIF              break           case MONOSPACE              tf   Typeface MONOSPACE              break            setTypeface tf  styleIndex           public void setTypeface Typeface tf  int style        if  style  gt  0            if  tf    null                tf   Typeface defaultFromStyle style             else               tf   Typeface create tf  style                      setTypeface tf              now compute what  if any  algorithmic styling is needed         int typefaceStyle   tf    null   tf getStyle     0          int need   style  amp   typefaceStyle          mTextPaint setFakeBoldText  need  amp  Typeface BOLD     0           mTextPaint setTextSkewX  need  amp  Typeface ITALIC     0   -0 25f   0         else           mTextPaint setFakeBoldText false           mTextPaint setTextSkewX 0           setTypeface tf             From the code We can see    if  fontFamily  is set  then the  typeface  will be ignored    typeface  has standard and limited valid values  In fact  the values are  normal   sans   serif  and  monospace   they can be found in system fonts xml 4 x  or fonts xml 5 x   Actually both  normal  and  sans  are the default font of system   fontFamily  can be used to set all fonts of build-in fonts  while  typeface   only provide the typical fonts of  sans-serif   serif  and  monospace  the three main category of font type in the world   When only set  textStyle   We actually set the default font and the specified style  The effective value are  normal   bold   italic  and  bold   italic
