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();  

    }
