How do I reproduce the numbered items in a Beamer list in text?

Question

I wrote a theorem in beamer with \enumerate. Then I need to write "Idea of proof of 1", with "1" which should be written the same way it appears in the theorem, ie a blue dot with a 1 inside. Also "1" must be written next to "Idea of proof of" and not at the head.

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\title{example}
\author[...]{...}
\usetheme{AnnArbor}
\useoutertheme[right]{sidebar}
\setbeamercovered{dynamic}
\theoremstyle{definition}
\newtheorem{definizione}{Definizione}
\theoremstyle{plain}
\newtheorem{theoremmm}{Theorem}
\begin{document}
\begin{frame}
\begin{theoremmm}
\begin{enumerate}
\item ...
\item ...
\end{enumerate}
\end{theoremmm}
Idea of proof of 1
\end{frame}
\end{document}

What written here (enumerate in itemize environment, no new line) solves my problem in LaTex, but the proposed solutions use \ enumitem, which does not work in Beamer.

HI and welcome. Please give a MWE : How to make a “minimum example” — AndréC, Aug 10 '20 at 14:35
Your code is not compilable. I got these error LaTeX Error: File "beamerthemePisa.sty" not found. Where did you find this Pisa theme ? — AndréC, Aug 10 '20 at 15:26
Does this question solve your problem? Getting the theme's itemize bullet in beamer? — AndréC, Aug 10 '20 at 15:57
+1 It's a real question ! Change the title of your question so that it is easy to understand and indexed by a search engine. For example, "How do I reproduce the numbered items in a Beamer list in text?" — AndréC, Aug 10 '20 at 16:33
@TobiBS This question is not duplicated, you are mistaken. Please retract your closing request. — AndréC, Aug 10 '20 at 20:40

You can use \usebeamertemplate{enumerate item} to show item label, for numbering the template use enumi counter.

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\title{example}
\author[...]{...}
\usetheme{AnnArbor}
\useoutertheme[right]{sidebar}
\setbeamercovered{dynamic}
\theoremstyle{definition}
\newtheorem{definizione}{Definizione}
\theoremstyle{plain}
\newtheorem{theoremmm}{Theorem}
\newcommand{\itemnum}[1]{%
\setcounter{enumi}{#1}\usebeamertemplate{enumerate item}% 
}
\begin{document}
\begin{frame}
\begin{theoremmm}
\begin{enumerate}
\item ...
\item ...
\end{enumerate}
\end{theoremmm}
Idea of proof of \itemnum{1} ...
\end{frame}
\end{document}

The enumerate bullet is defined in the beamer source code in the file beamerbaseauxtemplates.sty. You can copy the code from there and use it in a new command, where you supply an argument instead of the enumerate counter. The commands are listed as \defbeamertemplate{enumerate item}{ball} for the sphere, \defbeamertemplate{enumerate item}{circle} for the circle, and \defbeamertemplate{enumerate item}{square} for the square template.

For the circle template there is an additional font setting (with a \usebeamerfont command). You need to add a group (a pair of {} within the command) to prevent the font setting from taking effect outside of the command.

MWE:

\documentclass{beamer}
% sphere shape
\newcommand{\enumbullet}[1]{%
\begin{pgfpicture}{-1ex}{-0.65ex}{1ex}{1ex}
    \usebeamercolor{item projected}
    {\pgftransformscale{1.75}\pgftext{\normalsize\pgfuseshading{bigsphere}}}
    {\pgftransformshift{\pgfpoint{0pt}{0.5pt}}
      \pgftext{%
        \usebeamerfont*{item projected}%
        \color{fg}#1}}
  \end{pgfpicture}%
}
% circle shape
\newcommand{\enumcircle}[1]{%
  {\usebeamerfont*{item projected}%
  \usebeamercolor[bg]{item projected}%
  \begin{pgfpicture}{-1ex}{0ex}{1ex}{2ex}
    \pgfpathcircle{\pgfpoint{0pt}{.75ex}}{1.2ex}
    \pgfusepath{fill}
    \pgftext[base]{\color{fg}#1}
  \end{pgfpicture}}%
}
\usepackage[english]{babel}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\title{example}
\author[...]{...}
\usetheme{AnnArbor}
\useoutertheme[right]{sidebar}
\setbeamercovered{dynamic}
\theoremstyle{definition}
\newtheorem{definizione}{Definizione}
\theoremstyle{plain}
\newtheorem{theoremmm}{Theorem}
\begin{document}
\begin{frame}
\begin{theoremmm}
\begin{enumerate}
\item ...
\item ...
\end{enumerate}
\end{theoremmm}
Idea of proof of \enumbullet{1} and \enumbullet{2}
\end{frame}
\setbeamertemplate{enumerate item}[circle]
\begin{frame}
\begin{theoremmm}
\begin{enumerate}
\item ...
\item ...
\end{enumerate}
\end{theoremmm}
Idea of proof of \enumcircle{1} and \enumcircle{2}
\end{frame}
\end{document}

Result:

+1 Very nice answer! Can you add the exact name of the command you are using in your answer? — AndréC, Aug 10 '20 at 18:20
Thank you very much. What if I had to draw a circle with a "1" inside instead of a sphere with a "1" inside? — user222167, Aug 10 '20 at 20:54
@user222167 that is defined in the same template file, see edit. — Marijn, Aug 11 '20 at 07:10
Thank you very much. Why is "and" on the last line written in blue and not black? — user222167, Aug 11 '20 at 07:24
@user222167 I didn't see that, but Teepeemm was right, an extra group prevents the font setting from having effects outside of the command. — Marijn, Aug 11 '20 at 14:00
