java - update notification text every second -

-

I want to update every notification text I have written this code 

  New handler () Post Delayed (New Runnabel) {@Override public void run () {// TODO Auto-Generated Method Stub Builder.SetSamLicon (R.drawable. IC_Luncher); Builder.Sent ContentTitle ("text"); Builder.ContentText ("Value updated every 1 second");}}}, 1 * 1000);   
 But the price is not updated every 1 second, but only once. Why? How can I do this?   
 
 
 His code starts a thread that sleeps 1000 milliseconds each round.  
  Thread T = New thread () {@ Override Public Wide Run) {try {while (! Interrupt ()) {Thread.sleep (1000); RunOnUiThread (New Runnabel) {@ Override Public Wired Run ()} // // Update Text Here!}}); }} Grip (interrupted e) e} {}}}; T.start ();

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
