You have to use Handlers to update your UI. A little modification here,

new Thread() 
            {
                @Override
                public void run()
                    {
                        try
                        {
                           //Instead of sleep, call your http request method here. 
                           handler.sendEmptyMessage(0);
                         } 

                         catch (Exception e)
                          {

                          Log.e("tag", e.getMessage());

                          }
                           // dismiss the progress dialog
                           progressDialog.dismiss();
                    }

              }.start();

And create a handler in onCreate(),

 Handler handler=new Handler()
{
public void handleMEssage(Message msg)
{
 if(msg.what==0)
editText2.setText(stringEr);
}
};
