i'm trying to set text of text view in a while loop as 

 t = (TextView)findViewById(R.id.textView1);  
    while(true)  
    {  
     t.setText(hr+":"+":"min+":"+sec);  
      try{  
          Thread.sleep(1000);  
         }  
      catch(Exception e){}  
    }

But while running the app text is not changing. when i removed the while loop then it was setting
text correctly.
why was so? Plz Help!!!!!!!!!strong text

you never change the values of hr, min and sec. Also you are calling Thread.sleep(1000); on the UI Thread, which is responsable to draw the text in your text view. Of course, it will be unable to do that while it is sleeping.

  • i'm calling a method logic() as a first line in while loop in which i'm changing the values of hr,min,sec accordingly. but nevertheless it is not changing. when i remove only while loop and remaining body same then it works fine. Why is it so? – Dhruvam Gupta Nov 17 '14 at 04:13
