How to limit limit the users input in an edittext to everything but numbers

I would like to know how to stop the user from inputting numbers into my edittext programmatically, so that it has a similar effect as doing this would 

android:digits="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ#$%......"

I have looked at edittext.setInputType(InputType.something) but I could not find an input type which stops the user inputting numbers.

Does anyone know how I can do this either through an input type or some other method?

pavki_a's answer worked perfectly, but there were just a few bugs with the backspace and with the word suggestion. I fixed those by adding : 

edittext.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

This might be a problem if you want auto correct, but for me it worked fine

InputFilter filter = new InputFilter() {
    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
        String output = "";
        for (int i = start; i < end; i++) {
            if (!Character.isDigit(source.charAt(i))) { 
                    output += source.charAt(i); 
            }
        } 
        return output;
    } 
}; 
edit.setFilters(new InputFilter[]{filter});

assume edit is your EditText

According to http://developer.android.com/reference/android/widget/TextView.html#attr_android:inputType you can use

number - A numeric only field. Corresponds to TYPE_CLASS_NUMBER | TYPE_NUMBER_VARIATION_NORMAL.

Have you tried:

edit.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_NORMAL);
