在 beamer 中恢复嵌套枚举列表

Question

在 beamer 中，我想创建两个嵌套的枚举列表并继续数字，而不是像这样从头开始。

1. 
2. 
     3.
     4.   
5.
6. 

我的代码基于这个解决方案https://tex.stackexchange.com/a/531803/153274。

\documentclass{beamer}
\newcounter{currentenumi}
\begin{document}

\begin{frame}
    \frametitle{Plan}
    \begin{enumerate}
        \setbeamertemplate{enumerate items}[square]
        \item {\large Summary}
        \vskip1em
        \item {\large Research}
        \setcounter{currentenumi}{\theenumi}
        \vskip1em
        \begin{enumerate}
        \setcounter{enumi}{\thecurrentenumi}
            \item {\large Introduction}
            \vskip1em
            \item {\large Research During PhD}
            \vskip1em
            \item {\large Research During PostDoc}
        \end{enumerate}
        \vskip1em
        \item {\large Conclusions}
    \end{enumerate}
\end{frame}
\end{document}

我尝试过这个解决方案https://tex.stackexchange.com/a/55001/153274而且它也不起作用。

当您想要更改第二级枚举的计数器时，您enumii需要enumi：

\documentclass{beamer}
\newcounter{currentenumi}
\begin{document}

\begin{frame}
    \frametitle{Plan}
    \begin{enumerate}
        \setbeamertemplate{enumerate items}[square]
        \item {\large Summary}
        \vskip1em
        \item {\large Research}
        \setcounter{currentenumi}{\theenumi}
        \vskip1em
        \begin{enumerate}
        \setcounter{enumii}{\thecurrentenumi}
            \item {\large Introduction}
            \vskip1em
            \item {\large Research During PhD}
            \vskip1em
            \item {\large Research During PostDoc}
            \setcounter{currentenumi}{\theenumii}
        \end{enumerate}
        \vskip1em
        \setcounter{enumi}{\thecurrentenumi}
        \item {\large Conclusions}
    \end{enumerate}
\end{frame}
\end{document}
