Try this  For red color    lt string name  hello worldRed  gt  lt   CDATA  lt b gt  lt font color  FF0000 gt Hello world  lt  font gt  lt  b gt    gt  lt  string gt    For blue    lt string name  hello worldBlue  gt  lt   CDATA  lt b gt  lt font color  0000FF gt Hello world  lt  font gt  lt  b gt    gt  lt  string gt    In java code     red color text TextView redColorTextView    TextView findViewById R id redText   String redString   getResources   getString R string hello worldRed  redColorTextView setText Html fromHtml redString       Blue color text TextView blueColorTextView    TextView findViewById R id blueText   String blueString   getResources   getString R string hello worldBlue  blueColorTextView setText Html fromHtml blueString

Use CDATA in the below way for formatting your text   lt resources gt   lt string name  app name  gt DemoShareActionButton lt  string gt   lt string name  intro message  gt       lt b gt       lt   CDATA  This sample shows you how a provide a context-sensitive ShareActionProvider         gt       lt  b gt       lt  string gt      Just add any tag you want before the  lt   CDATA  and you will get your proper output

You do not set such attributes in strings xml type of files  You need to set it in your code  or  which is better solution  create style with colors you want and apply to your TextView

lt string name  hello world  gt  lt font fgcolor  red  gt Hello lt  font gt       lt  font fgcolor  blue  gt world  lt  font gt  lt  string gt    But note that this only works on a relatively short list of built-in colors  aqua  black  blue  fuchsia  green  grey  lime  maroon  navy  olive  purple  red  silver  teal  white  and yellow  See https   stackoverflow com a 31655150 338479 for a way to do it with arbitrary colors

You don t  strings xml is just here to define the raw text messages  You should  must  use styles xml to define reusable visual styles to apply to your widgets   Think of it as a good practice to separate the concerns  You can work on the visual styles independently from the text messages

If you want to support text formatting from within your strings xml file  you have to escape the tags     or use a CDATA section   Otherwise Android simply ignores them when reading the resource file   e g   lt string name  hello world  gt   lt   CDATA   lt p gt This is a html-formatted string with  lt b gt bold lt  b gt  and  lt i gt italic lt  i gt  text lt  p gt   lt p gt This is another paragraph of the same string  lt  p gt     gt   lt  string gt    OR  String styledText    This is  lt font color  red  gt simple lt  font gt     textView setText Html fromHtml styledText   TextView BufferType SPANNABLE

I would use a SpannableString to change the color    int colorBlue   getResources   getColor R color blue       String text   getString R string text       SpannableString spannable   new SpannableString text          here we set the color     spannable setSpan new ForegroundColorSpan colorBlue   0  text length    0     OR you may try this

Just add your text between the font tags   for blue color   lt string name  hello world  gt  lt font color  blue  gt Hello world  lt  font gt  lt  string gt    or for red color   lt string name  hello world  gt  lt font color  red  gt Hello world  lt  font gt  lt  string gt
