        et.addTextChangedListener( new TextWatcher()
        {
            @Override
            public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {

                try
                {
                    char currentChar = arg0.charAt(arg1); // currently typed character
                }
                catch(Exception e)
                {
                    // error
                }
            }

            @Override
            public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                    int arg3) {

            }

            @Override
            public void afterTextChanged(Editable arg0) {

            }
        });
