Try this, I simply edited the code you provided....

InputFilter[] timeFilter = new InputFilter[1];

timeFilter[0] = new InputFilter() {
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {

        if (source.length() == 0) {
            return null;// deleting, keep original editing
        }

        String result = "";
        result += dest.toString().substring(0, dstart);
        result += source.toString().substring(start, end);
        result += dest.toString().substring(dend, dest.length());

        if (result.length() > 5) {
            return "";// do not allow this edit
        }

        boolean allowEdit = true;
        char c;
        if (result.length() > 0) {
            c = result.charAt(0);
            allowEdit &= (c >= '0' && c <= '2' && !(Character.isLetter(c)));
        }

        if (result.length() > 1) {
            c = result.charAt(1);
            allowEdit &= (c >= '0' && c <= '9' && !(Character.isLetter(c)));
        }

        if (result.length() > 2) {
            c = result.charAt(2);
            allowEdit &= (c == ':'&&!(Character.isLetter(c)));
        }

        if (result.length() > 3) {
            c = result.charAt(3);
            allowEdit &= (c >= '0' && c <= '5' && !(Character.isLetter(c)));
        }

        if (result.length() > 4) {
            c = result.charAt(4);
            allowEdit &= (c >= '0' && c <= '9'&& !(Character.isLetter(c)));
        }

        return allowEdit ? null : "";
    }
};

This works absolutely fine for me. Accepts time in format hh:mm only (no other character accepted)
