Meta标签上的Thymeleaf功能(Thymeleaf functionality on Meta tag)

 我不确定这是否是已知的情况。 但是我很困惑，因为我找不到任何讨论。 
 

 提高我的澄清。 基于thymeleaf的html页面是否允许meta标签位于其头部？ 
 

 我有这样的代码 ： 
 

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
   <head>
      <title>Data Services Platform Support</title>
      <div th:replace="fragments/header :: header-css" />
      <script
         src="https://cdnjs.cloudflare.com/ajax/libs/angular-smart-table/2.1.8/smart-table.min.js"></script>
      <link rel="stylesheet"
         href="https://fonts.googleapis.com/css?family=Open+Sans" />
      <link rel="stylesheet" type="text/css"
         href="webjars/bootstrap/3.3.7/css/bootstrap.min.css" />
      <link rel="stylesheet" th:href="@{/css/main.css}"
         href="../../css/main.css" />
      <script
         src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
      <script
         src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
   </head>
   <body>
      ...
   </body>
</html>

 

 它显示我正在寻找的页面。 
 

 但是，当我尝试添加meta标记来升级我的页面时，只有很少的功能（需要meta标记）， 所以白标错误页面就是我所得到的。 
 

 我修改的代码 ： 
 

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
   <head>
      <title>Data Services Platform Support</title>
      <meta charset="utf-8">
      <meta name="viewport" content="width=device-width, initial-scale=1">
      <div th:replace="fragments/header :: header-css" />
      <script
         src="https://cdnjs.cloudflare.com/ajax/libs/angular-smart-table/2.1.8/smart-table.min.js"></script>
      <link rel="stylesheet"
         href="https://fonts.googleapis.com/css?family=Open+Sans" />
      <link rel="stylesheet" type="text/css"
         href="webjars/bootstrap/3.3.7/css/bootstrap.min.css" />
      <link rel="stylesheet" th:href="@{/css/main.css}"
         href="../../css/main.css" />
      <script
         src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
      <script
         src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
   </head>
   <body>
      ...
   </body>
</html>

 

 有什么我需要考虑的吗？ 请帮忙。 

I'm not sure if this could be a known scenario. But I'm confused since I couldn't find any discussions on this.
 

Raising my clarification. Does thymeleaf based html page allow meta tags within its head?
 

I've this code:
 

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
   <head>
      <title>Data Services Platform Support</title>
      <div th:replace="fragments/header :: header-css" />
      <script
         src="https://cdnjs.cloudflare.com/ajax/libs/angular-smart-table/2.1.8/smart-table.min.js"></script>
      <link rel="stylesheet"
         href="https://fonts.googleapis.com/css?family=Open+Sans" />
      <link rel="stylesheet" type="text/css"
         href="webjars/bootstrap/3.3.7/css/bootstrap.min.css" />
      <link rel="stylesheet" th:href="@{/css/main.css}"
         href="../../css/main.css" />
      <script
         src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
      <script
         src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
   </head>
   <body>
      ...
   </body>
</html>

 

which displays the page I'm looking for.
 

But when I tried adding the meta tag to upgrade my page with few functionalities(which require a meta tag), Whitelabel Error Page is all what I get.
 

My modified code:
 

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
   <head>
      <title>Data Services Platform Support</title>
      <meta charset="utf-8">
      <meta name="viewport" content="width=device-width, initial-scale=1">
      <div th:replace="fragments/header :: header-css" />
      <script
         src="https://cdnjs.cloudflare.com/ajax/libs/angular-smart-table/2.1.8/smart-table.min.js"></script>
      <link rel="stylesheet"
         href="https://fonts.googleapis.com/css?family=Open+Sans" />
      <link rel="stylesheet" type="text/css"
         href="webjars/bootstrap/3.3.7/css/bootstrap.min.css" />
      <link rel="stylesheet" th:href="@{/css/main.css}"
         href="../../css/main.css" />
      <script
         src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
      <script
         src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
   </head>
   <body>
      ...
   </body>
</html>

 

Is there something I need to consider? Please help.

 事实证明，修复起来非常简单 
 

public class SpoilerSpan extends ClickableSpan {
    private boolean clicked = false;

    @Override
    public void onClick(View widget) {
        clicked = true;
        widget.invalidate();
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        if (!clicked){
            ds.setColor(Color.argb(255, 00, 00, 00)); //FF000000
            ds.bgColor = Color.argb(255, 00, 00, 00); //FF000000
            ds.setUnderlineText(false);
        }
    }
}


Turns out it was really simple to fix
 

public class SpoilerSpan extends ClickableSpan {
    private boolean clicked = false;

    @Override
    public void onClick(View widget) {
        clicked = true;
        widget.invalidate();
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        if (!clicked){
            ds.setColor(Color.argb(255, 00, 00, 00)); //FF000000
            ds.bgColor = Color.argb(255, 00, 00, 00); //FF000000
            ds.setUnderlineText(false);
        }
    }
}
