@Override
public void afterTextChanged(Editable s) {
    if(s.trim.length() > 0)
            {
                 int start = s.toString().length() - 1;
                 int a = (int) s.charAt(start);
                 if (!(a >= 48 && a <= 57 || a == 44))
                    s = s.delete(start, start + 1);
            }
}

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

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