Android中验证输入是否为汉字、手机号及邮箱

1，验证是否为汉字

Code// 验证昵称
private boolean verifyNickname() {
        String nickname = edt_username.getText().toString();
if (nickname == null || nickname.length() == 0) {
            edt_username.setError("不能为空");
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("正确的昵称应该为\n1、4-15个字符\n2、2-7个汉字\n3、不能是邮箱和手机号");
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，验证手机号，邮箱

Code// 判断是否为手机号
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();
    }  

// 判断格式是否为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();
    }
