Android中驗證輸入是否為漢字及手機號，郵箱驗證，android漢字

1，驗證是否為漢字

// 驗證暱稱    private boolean verifyNickname() {        String nickname = edt_username.getText().toString();        if (nickname == null || nickname.length() == 0) {            edt_username.setError("不可為空");            return false;        }        int len = 0;        char[] nickchar = nickname.toCharArray();        for (int i = 0; i < nickchar.length; i++) {            if (isChinese(nickchar[i])) {                len += 2;            } else {                len += 1;            }        }        if (len < 4 || len > 15) {            edt_username.setError("正確的暱稱應該為\n1、4-15個字元\n2、2-7個漢字\n3、不能是郵箱和手機號");            return false;        }        return true;    }    private boolean isChinese(char c) {        Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);        if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS                || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS                || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A                || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION                || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION                || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {            return true;        }        return false;    }

2，驗證手機號，郵箱

// 判斷是否為手機號    private boolean isPhone(String inputText) {        Pattern p = Pattern                .compile("^((13[0-9])|(15[^4,\\D])|(18[0,5-9]))\\d{8}$");        Matcher m = p.matcher(inputText);        return m.matches();    }    // 判斷格式是否為email    public boolean isEmail(String email) {        String str = "^([a-zA-Z0-9_\\-\\.]+)@((\\[[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.)|(([a-zA-Z0-9\\-]+\\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\\]?)$";        Pattern p = Pattern.compile(str);        Matcher m = p.matcher(email);        return m.matches();    }
