   /*Breaf into of Linkyfy class :Linkify take a piece of text and a regular expression and turns
    *all of the regex matches in the text into clickable links. This is particularly useful for
    *matching things like email addresses, web urls, etc. and making them actionable. Alone with
    *the pattern that is to be matched, a url scheme prefix is also required.
    *Any pattern match that does not begin with the supplied scheme will have the scheme
    *prepended to the matched text when the clickable url is created. For instance, if you
    *are matching web urls you would supply the scheme http://. If the pattern matches example.com,
    *which does not have a url scheme prefix, the supplied scheme will be prepended to create 
    *http://example.com when the clickable url link is created. 
    */
   Linkify.addLinks(TVAutoLink, Linkify.ALL); // linkify all links in text.
   //you can set link color with the help of text view property
   TVAutoLink.setLinkTextColor(Color.GREEN);
