If using TextViews in tabs this selector definition worked for me  tried Klaus Balduino s but it did not     lt  xml version  1 0  encoding  utf-8   gt       lt selector xmlns android  http   schemas android com apk res android  gt      lt  --  Active tab -- gt     lt item     android state selected  true      android state focused  false      android state pressed  false      android color   000000    gt      lt  --  Inactive tab -- gt     lt item     android state selected  false      android state focused  false      android state pressed  false      android color   FFFFFF    gt    lt  selector gt

Have you tried setOnFocusChangeListener  Within the handler  you could change the text appearance   For instance   TextView text    TextView findViewById R id text   text setOnFocusChangeListener new View OnFocusChangeListener         public void onFocusChange View v  boolean hasFocus            if  hasFocus                  TextView v  setXXXX              else                 TextView v  setXXXX                          You can then apply whatever changes you want when it s focused or not  You can also use the ViewTreeObserver to listen for Global focus changes   For instance   View all   findViewById R id id of top level view on layout   ViewTreeObserver vto   all getViewTreeObserver    vto addOnGlobalFocusChangeListener new ViewTreeObserver OnGlobalFocusChangeListener         public void onGlobalFocusChanged          View oldFocus  View newFocus               xxxx             I hope this helps or gives you ideas

I always used the above solution without searching more after this   -   However  today I came across something and thought of sharing it      This feature is indeed available from API 1 and is called as ColorStateList  where we can supply a color to various states of Widgets  as we already know    It is also very well documented  here

In res color place a file  text selector xml     lt  xml version  1 0  encoding  utf-8   gt   lt selector xmlns android  http   schemas android com apk res android  gt       lt item android color   color blue  android state focused  true    gt       lt item android color   color blue  android state selected  true    gt       lt item android color   color green    gt   lt  selector gt    Then in TextView use it    lt TextView     android id    id value 1      android layout width  match parent      android layout height  wrap content      android text  Text      android textColor   color text selector      android textSize  15sp        gt    And in code you ll need to set a click listener   private var isPressed   false  private fun TextView setListener         this setOnClickListener   v - gt          run               if  isPressed                    v isSelected   false                 v clearFocus                 else                   v isSelected   true                 v requestFocus                             isPressed    isPressed                    override fun onResume         super onResume       textView setListener      override fun onPause         textView setOnClickListener null      super onPause       Sorry if there are errors  I changed a code before publishing and didn t check

In order to make it work on selection in a list view use the following code     lt selector xmlns android  http   schemas android com apk res android  gt       lt item android state pressed  true  android color   fff   gt       lt item android state activated  true  android color   fff   gt       lt item android color   000    gt   lt  selector gt    Apparently the key is state activated  true  state

And selector is the answer here as well   Search for bright text dark focused xml in the sources  add to your project under res color directory and then refer from the TextView as  android textColor   color bright text dark focused

Here is the example of selector  If you use eclipse   it does not suggest something when you  click ctrl and space both    you must type it    lt selector xmlns android  http   schemas android com apk res android  gt   lt item android drawable   drawable btn default pressed  android state pressed  true    gt   lt item android drawable   drawable btn default selected      android state focused  true      android state enabled  true      android state window focused  true     gt   lt item android drawable   drawable btn default normal    gt      You can look at for reference   http   developer android com guide topics resources drawable-resource html StateList
