Android EditText : How to avoid user enter smileys?

Question

I would like to avoid to the user to put a smiley with the keyboard into an EditText. Is it possible ?

enter image description here

you just want to avoid smilies and allow every thing or you just to allow text + numbers only (not special characters)? please clarify. — SMR, Jun 27 '14 at 09:23

Editing answer from here.

This will allow only ASCII characters to be entered in EditText.

edittext.setFilters(new InputFilter[] {
 new InputFilter() {
    public CharSequence filter(CharSequence src, int start,
            int end, Spanned dst, int dstart, int dend) {
        if(src.equals("")){ // for backspace
            return src;
        }
        if(src.toString().matches("[\\x00-\\x7F]+")){
            return src;
        }
        return "";
    }
 }
});

I simply did: `return source.toString().matches("\\S") ? source : "";` and it is working. The \S allows anything but white-space (line breaks, tabs, spaces, hard spaces). – Dick Lucas Nov 01 '16 at 16:05

but when you click emoji, then click backspace, 2 characters will be deleted from the current text – HendraWD May 29 '17 at 13:30

You can define your input type and only accept letters or change your keyboard type:

Or you can only accept some specific digits:
