章节标题和框架标题之间的进度条上的框架编号 - Metropolis Beamer

Question

我希望框架结构如下：

-- 章节标题 --

-- 进度条上的帧编号分数（最右端）--

-- 框架标题 --

-- 框架内容 --

通过 metropolis，利用 StackExchange 上的旧问题，我得到了以下信息：

\documentclass[lualatex]{beamer}
\usetheme[progressbar=head]{metropolis} 
\metroset{numbering=fraction}

\makeatletter
\setlength{\metropolis@progressinheadfoot@linewidth}{1em}

\setbeamertemplate{headline}{% 
    \begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}
    \end{beamercolorbox}
    \begin{beamercolorbox}{section in head/foot}
        \vskip2pt\insertnavigation{\paperwidth}\vskip2pt
    \end{beamercolorbox}%
    \begin{beamercolorbox}[colsep=1.5pt]{lower separation line head}
    \end{beamercolorbox}
}

\def\beamer@writeslidentry{\clearpage\beamer@notesactions}  
\makeatother

\setbeamercolor{section in head/foot}{fg=black, bg=white}

\begin{document}

\section{section title}

\begin{frame}{frame title}

first line

second line

\end{frame}

\end{document}

此代码设法将部分和进度条放在顶部，后者元素被前者覆盖，并使用帧号分数。

主题moloch（主题的更现代分支metropolis）使用标题模板来显示进度条。如果您使用，\setbeamertemplate{headline}{...}则不会覆盖进度条，而是将其完全删除。您可以改为使用\addtobeamertemplate{headline}{<before>}{<after>}在标题中添加内容，而无需主动删除已经存在的进度条：

\documentclass{beamer}
\usetheme[progressbar=head]{moloch}% modern fork of the metropolis theme

\setbeamertemplate{page number in head/foot}[totalframenumber]

\usepackage{tikz}

\makeatletter
\setlength{\moloch@progressinheadfoot@linewidth}{1em}

\addtobeamertemplate{headline}{% 
    \begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}
    \end{beamercolorbox}
    \begin{beamercolorbox}{section in head/foot}
        \vskip2pt\insertnavigation{\paperwidth}\vskip2pt
    \end{beamercolorbox}%
    \begin{beamercolorbox}[colsep=1.5pt]{lower separation line head}
    \end{beamercolorbox}
    \par
}{}

\setbeamertemplate{footline}{
    \begin{tikzpicture}[remember picture,overlay]
      \node[anchor=north east] at ([yshift=-5.5ex]current page.north east) {\usebeamercolor[fg]{page number in head/foot}\usebeamertemplate{page number in head/foot}};
    \end{tikzpicture}
}

\def\beamer@writeslidentry{\clearpage\beamer@notesactions}  
\makeatother

\setbeamercolor{section in head/foot}{fg=black, bg=white}

\setbeamercolor{page number in head/foot}{fg=mLightBrown}

\begin{document}

\section{section title}

\begin{frame}
\frametitle{frame title}

first line

second line

\end{frame}

\begin{frame}
\frametitle{frame title}

first line

second line

\end{frame}

\end{document}
