how to update the textview variable for every 5 seconds [duplicate]

Answer 1

use Handler or TimerTask(with runOnUiThread()) instead of for loop for updating text after every 5 seconds as :

Handler handler=new Handler();  

handler.post(runnable);  
Runnable runnable=new Runnable(){  
  @Override  
    public void run() {  
      settext(string.valueof(Hr));  //<<< update textveiw here
      handler.postDelayed(runnable, 5000);  
     }  
 };
