Android EditText : How to avoid user enter smileys?


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

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

<blockquote> <blockquote>

</blockquote> </blockquote>

Or you can only accept some specific digits:

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 ""; } } });
