关于删除投影仪中的页码的问题

Question

我怎样才能在 Beamer 中为初始幻灯片编号，而让最后一张幻灯片不编号？我尝试指定最后一张幻灯片的样式为普通样式，因此不编号。但是，最后一张幻灯片的页码仍然显示，只是向下移动了。问题出在哪里？

梅威瑟：

\documentclass{beamer}
\usepackage[english]{babel}

\beamertemplatenavigationsymbolsempty

\addtobeamertemplate{navigation symbols}{}{\insertframenumber}

\begin{document}
    \begin{frame}
        This slide is numbered, as it should be.
    \end{frame}

    \begin{frame}[plain]
        This slide is also numbered, but I don't want it to be.
    \end{frame}
\end{document}

Answer 1

尝试一下这个代码。

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty

%\setbeamertemplate{footline}{% add only the frame number
%   \hfill%
%   \setbeamertemplate{page number in head/foot}[framenumber]%
%   \usebeamertemplate*{page number in head/foot}\kern1em\vskip3pt%
%}

\setbeamertemplate{footline}[frame number]% frame number /total frames

\begin{document}

    \begin{frame}
        This slide 1 is numbered, as it should be.
    \end{frame}
    
    \begin{frame}[plain]
    %   \addtocounter{framenumber}{-1} % OPTIONAL start next frame with #2
        This slide 2 is also numbered, but I don't want it to be.
        
        (Not anymore)   
    \end{frame}

    \begin{frame}
        This slide 3 is numbered, as it should be.
    \end{frame}

    \begin{frame}[plain]    
        This slide 4 is the last one and it is also not numbered.
    \end{frame}
    
\end{document}

帧的编号为帧号/总帧数。

如果你只想要帧号替换

\setbeamertemplate{footline}[frame number]

经过

\setbeamertemplate{footline}{% add only the frame number
        \hfill%
        \setbeamertemplate{page number in head/foot}[framenumber]%
        \usebeamertemplate*{page number in head/foot}\kern1em\vskip3pt%
    }

如果希望第三张幻灯片以数字 2 而不是 3 开头，请添加到第二帧

\addtocounter{framenumber}{-1}
