title: Textview text color not changing on click
body: <p>I have an activity in which I have created a table dynamically. The table is populated from a SQLite database. Onclick the table header the table is getting sorted accordingly.</p>
  
  <p>Everything is working fine, now my requirement is to change the text color of the table header textview when it is clicked. The text color is not getting changed.</p>
  
  <p>This is the a <strong>method which is populating the table</strong>:</p>
