Android: On EditText Changed Listener

up vote60down votefavorite 14

In my project I have a EditText. I want to show how many characters are there in the EditText and show it in the TextView. I have written following code and it works fine. However, my problem is when I click Backspace it counts up. I need to decrement the number. What should I do? How can I take Backspace Key? tv = (TextView)findViewById(R.id.charCounts); textMessage = (EditText)findViewById(R.id.textMessage); textMessage.addTextChangedListener(new TextWatcher(){ public void afterTextChanged(Editable s) { i++; tv.setText(String.valueOf(i) + " / " + String.valueOf(charCounts)); } public void beforeTextChanged(CharSequence s, int start, int count, int after){} public void onTextChanged(CharSequence s, int start, int before, int count){} }); android listener edittext onchange share|improve this question
