If you have got SeekBar working and EditText initialized then you must know that the values would change with the method below.

And this is what you should do,

public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
               yourEditText.setText("changing values are "+progress);
            }

Call the above function inside onprogresschanged as I have shown above http://stackoverflow.com/a/6124165/1503130 this might solve your problem. But all you need to do inside the above function. – Prateek Feb 23 '13 at 07:56
