Beamer - 计数定理和块的颜色

Question

为什么它无法对我新定义的定理块进行计数。我可以更改块的颜色吗？

\documentclass{beamer}
\newtheorem{teorem}{Teorem}[section]
\newtheorem{definicija}{Definicija}[section]
\newtheorem{lema}{Lema}[section]
\newtheorem{primjer}{Primjer}[section]
\newtheorem{conjecture}{Konjektura}[section]
\usepackage[mathscr]{eucal}
\usepackage[utf8]{inputenc} 
\usepackage[croatian]{babel}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{latexsym}
\usepackage{hyperref}

Beamer 有一个内置数字定理选项，你可以使用以下命令激活它\setbeamertemplate{theorems}[numbered]

\setbeamertemplate{theorems}[numbered]

\AtBeginEnvironment{teorem}{%
    \setbeamercolor{block title}{fg=white,bg=red}
    \setbeamercolor{block body}{fg=black,bg=red!40}
}

评论

• 请不要加载两次包，例如\usepackage{amsfonts}, \usepackage{amssymb}

• 由于 beamer 本身已经提供了这些功能，因此无需加载hyperref, color, graphicx, graphics

要在标题中显示章节编号，请尝试

\usepackage{xpatch}
\makeatletter
\patchcmd\beamer@@tmpl@frametitle{\insertframetitle}{\thesection.~\insertframetitle}{}{}
\makeatother
