In Kotlin I have created an extension function for the Context  It takes a  StringRes and optionally you can provide parameters as well  fun Context fromHtmlWithParams  StringRes stringRes  Int  parameter   String    null    Spanned        val stringText   if  parameter isNullOrEmpty                          this getString stringRes                    else                       this getString stringRes  parameter                         return Html fromHtml stringText  Html FROM HTML MODE LEGACY      Usage tv directors text   context  fromHtmlWithParams R string directors  movie Director

You could basically use html tags in your string resource like     lt resource gt       lt string name  styled welcome message  gt We are  lt b gt  lt i gt so lt  i gt  lt  b gt  glad to see you  lt  string gt   lt  resources gt    And use Html fromHtml or use spannable  check the link I posted    Old similar question  Is it possible to have multiple styles inside a TextView

As David Olsson has said  you can use HTML in your string resources    lt resource gt       lt string name  my string  gt A string with  lt i gt actual lt  i gt   lt b gt formatting lt  b gt   lt  string gt   lt  resources gt    Then if you use getText R string my string  rather than getString R string my string  you get back a CharSequence rather than a String that contains the formatting embedded

If you want to store formatted as a string variable and reuse it to text view isn t possible  If you aren t applying formatting  you can set TextView text directly by calling setText java lang CharSequence   In some cases  however  you may want to create a styled text resource that is also used as a format string  Normally  this doesn t work because the format String  Object     and getString int  Object     methods strip all the style information from the string  The work-around to this is to write the HTML tags with escaped entities  which are then recovered with fromHtml String   after the formatting takes place   by from docs so alternatively store the string id and everyttime bind get string from using Htlm fromHtml     method  ex  Kotlin extention fun Context getStringFromResource stringId  Int   Spanned       return if  Build VERSION SDK INT  gt   Build VERSION CODES N            Html fromHtml java lang String format resources getString stringId      Html FROM HTML MODE COMPACT        else           Html fromHtml java lang String format resources getString stringId             In code  getStringFromResource id
