In my app, I want to count the number of charters in the edittext..,and after the character count has reached to a limit, counter should again start with 140 and I want to display it in the format of " 140/1 ",after character limit reached to 0 .,it again stat with 140 but with increment in 1 by 1,and display as "140/2".how can i do that any suggestion..??

edMessage.addTextChangedListener(new TextWatcher() {

            public void onTextChanged(CharSequence s, int start, int before, int count) {
                // TODO Auto-generated method stub

            }

            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
                // TODO Auto-generated method stub

            }

            public void afterTextChanged(Editable s) {

                // Display Remaining Character with respective color
                 count = MAX_COUNT - s.length();
               Word_counter.setText(Integer.toString(count) + "/" + Integer.toString(word)  );

               Word_counter.setTextColor(Color.BLACK);
                if(count < 10)
                {
                     Word_counter.setTextColor(Color.YELLOW);
                }


            }
        });
