EditText限制输入数字+字母+中文

//昵称仅支持10位字母/数字/中文
        //限制只能输入中文，英文，数字
        InputFilter typeFilter = new InputFilter() {
            @Override
            public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
                Pattern p = Pattern.compile("[0-9a-zA-Z|\u4e00-\u9fa5]+");
                Matcher m = p.matcher(source.toString());
                if (!m.matches()) return "";
                return null;
            }
        };


        //如果要限制输入字数，数组中加上new InputFilter.LengthFilter(maxLength)
        vEtNickName.setFilters(new InputFilter[]{typeFilter, new InputFilter.LengthFilter(10)});
