Using Kotlin and Extensions you can add colored text really easy and clean  Create a file TextViewExtensions kt with this content fun TextView append string  String    ColorRes color  Int        if  string    null    string isEmpty              return            val spannable  Spannable   SpannableString string      spannable setSpan          ForegroundColorSpan ContextCompat getColor context  color            0          spannable length          Spannable SPAN EXCLUSIVE EXCLUSIVE            append spannable     Now is really easy to append text with color textView text    quot  quot     Remove old text textView append  quot Red Text quot   R color colorAccent  textView append  quot White Text quot   android R color white   Basically is same as  Abdul Rizwan answer but using Kotlin  extensions  some validations and getting color inside extension

You can use Spannable to apply effects to your TextView   Here is my example for colouring just the first part of a TextView text  while allowing you to set the color dynamically rather than hard coding it into a String as with the HTML example        mTextView setText  Red text is here   BufferType SPANNABLE       Spannable span    Spannable  mTextView getText        span setSpan new ForegroundColorSpan 0xFFFF0000   0   Red  length                 Spannable SPAN INCLUSIVE EXCLUSIVE     In this example you can replace 0xFFFF0000 with a getResources   getColor R color red

Awesome answers  I was able to use Spannable to build rainbow colored text  so this could be repeated for any array of colors   Here s my method  if it helps anyone   private Spannable buildRainbowText String pack name            int   colors   new int   Color RED  0xFFFF9933  Color YELLOW  Color GREEN  Color BLUE  Color RED  0xFFFF9933  Color YELLOW  Color GREEN  Color BLUE  Color RED  0xFFFF9933  Color YELLOW  Color GREEN  Color BLUE  Color RED  0xFFFF9933  Color YELLOW  Color GREEN  Color BLUE           Spannable word   new SpannableString pack name           for int i   0  i  lt  word length    i                  word setSpan new ForegroundColorSpan colors i    i  i 1  Spannable SPAN EXCLUSIVE EXCLUSIVE                     return word          And then I just setText buildRainboxText pack name    Note that all of the words I pass in are under 15 characters and this just repeats 5 colors 3 times - you d want to adjust the colors length of the array for your usage

I don t know  since when this is possible  but you can simply add  lt font gt   lt  font gt  to your string xml which will automatically change the color per text  No need to add any additional code such as spannable text etc  Example  lt string name  quot my formatted text quot  gt       lt font color  quot  FF0707 quot  gt THIS IS RED lt  font gt       lt font color  quot  0B132B quot  gt AND NOW BLUE lt  font gt   lt  string gt

Use SpannableBuilder class instead of HTML formatting where it possible because it more faster then HTML format parsing  See my own benchmark  SpannableBuilder vs HTML  on Github Thanks

Since API 24 you have FROM HTML OPTION USE CSS COLORS so you can define colors in CSS instead of repeating it all time with font color    Much clearer - when you have some html and you want to highlight some predefined tags - you just need to add CSS fragment at top of your html
