Most likely you need to use TextWatcher that it pretty designated for your goal and allows you to manipulate with content of EditText in realtime.

Example:

edittext.addTextChangedListener(new TextWatcher() {

    public void onTextChanged(CharSequence s, int start, int before, int count) {           

    }

    public void beforeTextChanged(CharSequence s, int start, int count, int after) {    

    }

    public void afterTextChanged(Editable s) {

    }
});
