title: Android. Default text color
body: <p>Hallo everybody,</p>
  
  <p>I'd like to use black color as default text color only in one activity. </p>
  
  <p>I guess, I should use Theme and Styles, but I didn't find any good information relating to my question or to only one activity.</p>
  
  <p>Is it possible to change default text color only for one activity?</p>
  
  <p>If yes, could you give me an example please, how to do this?</p>
