android 中限制 eidttext输入emjoy表情

最近项目中遇到个不让Edittext输入Emjoy表情的需求，查找很多资料后最后用CSDN上一个哥们的方法解决

EditText et = (EditText)findViewById(R.id.et);

et.setFilters(new InputFilter[]{emojiFilter});

/**

* 过滤emoj表情

*/

InputFilter emojiFilter = new InputFilter() {

Pattern emoji = Pattern

.compile("[\ud83c\udc00-\ud83c\udfff]|[\ud83d\udc00-\ud83d\udfff]|[\u2600-\u27ff]",Pattern.UNICODE_CASE | Pattern.CASE_INSENSITIVE);

@Override

public CharSequence filter(CharSequence source, int start, int end,

Spanned dest, int dstart,int dend) {

Matcher emojiMatcher = emoji.matcher(source);

if (emojiMatcher.find()) {

return "";

}

return null;

}

};
