Android中验证输入是否为汉字及手机号，邮箱验证

1，验证是否为汉字
		// 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
		// 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();
		    }
