提出问题和答案

这是该主题的延续显示编号的问题和答案。

我继续给背景上色，然后把问题和答案放在方框里，使用框架包裹。

第一个问题

如何设置标题位于页面的中间？

我添加了一个命令：

\begin{frame}
    \vspace{15pt}
    \titlepage
\end{frame}

但不起作用。

第二个问题

首府

在显示答案之前，有一个空白的文本框。

第一个问题

答案1

对于第一个问题，我重新定义了title page模板，只包含标题和作者。对于第二个问题，你可以\only使用\pause：

\documentclass{beamer}
\setbeamercovered{transparent=0}
\setbeamercolor{background canvas}{bg=lime!20}

\usepackage{xcolor}
\usepackage{transparent}

\usepackage[framemethod=TikZ]{mdframed}
\mdfdefinestyle{QueFrame}{%
    linecolor       = blue!30,
    outerlinewidth      = 2pt,
    roundcorner     = 10pt,
    leftmargin      = 10pt,
    rightmargin     = 80pt,
    innertopmargin      = \baselineskip,
    innerbottommargin   = \baselineskip,
    innerrightmargin    = 20pt,
    innerleftmargin     = 20pt,
    backgroundcolor     = red!20!white
}

\mdfdefinestyle{AnsFrame}{
    linecolor       = red!30,
    outerlinewidth      = 2pt,
    roundcorner     = 10pt,
    leftmargin      = 80pt,
    rightmargin     = 10pt,
    innertopmargin      = \baselineskip,
    innerbottommargin   = \baselineskip,
    innerrightmargin    = 20pt,
    innerleftmargin     = 20pt,
    backgroundcolor     = blue!20!white

答案2

问题在于\Que和的定义\Ans：

\newcommand<>\Que[1]{
    \leavevmode\par
    \stepcounter{num}
    \noindent
    \begin{mdframed}[style=QueFrame]    
        \hbox{          
        {\color{blue}\transparent{0.3}\Huge Q{\huge\thenum}} --- #1}
    \end{mdframed} 
}

\newcommand<>\Ans[2][]{
    \leavevmode\par
    \noindent
    \begin{flushright}
        \begin{mdframed}[style=AnsFrame]
            \textbf{#1} #2  --- {\Huge\color{blue}\transparent{0.3} A}
        \end{mdframed}
    \end{flushright}
}

您正在定义覆盖感知命令，但未明确使用覆盖规范。将定义更改为：

\newcommand<>\Que[1]{
    \leavevmode\par
    \stepcounter{num}
    \noindent
    \only#2{\begin{mdframed}[style=QueFrame]    
        \hbox{          
        {\color{blue}\transparent{0.3}\Huge Q{\huge\thenum}} --- #1}
    \end{mdframed}}
}

\newcommand<>\Ans[2][]{
    \leavevmode\par
    \noindent
    \begin{flushright}
        \only#3{\begin{mdframed}[style=AnsFrame]
            \textbf{#1} #2  --- {\Huge\color{blue}\transparent{0.3} A}
        \end{mdframed}}
    \end{flushright}
}

允许使用：

\begin{frame}
    \Que<1->{What is \LaTeX{}?}
    \Ans<2->{\LaTeX{} is a document preparation system and document markup language!}
\end{frame}

\begin{frame}
    \Que<1->{Why I should use \LaTeX?}
    \Ans<2->{\LaTeX{} provides very high quality. \LaTeX{} is free and Open Source!}
\end{frame}

完整示例：

\documentclass{beamer}
\usepackage{lmodern}
\setbeamercovered{transparent=0}
\setbeamercolor{background canvas}{bg=lime!20}

\usepackage{transparent}

\usepackage[framemethod=TikZ]{mdframed}

    roundcorner     = 10pt,
    leftmargin      = 10pt,
    rightmargin     = 80pt,
    innertopmargin      = \baselineskip,
    innerbottommargin   = \baselineskip,
    innerrightmargin    = 20pt,
    innerleftmargin     = 20pt,
    backgroundcolor     = red!20!white
}

\mdfdefinestyle{AnsFrame}{
    linecolor       = red!30,
    outerlinewidth      = 2pt,
    roundcorner     = 10pt,
    leftmargin      = 80pt,
    rightmargin     = 10pt,
    innertopmargin      = \baselineskip,
    innerbottommargin   = \baselineskip,
    innerrightmargin    = 20pt,
    innerleftmargin     = 20pt,
    backgroundcolor     = blue!20!white

    \noindent

        \only#3{\begin{mdframed}[style=AnsFrame]
            \textbf{#1} #2  --- {\Huge\color{blue}\transparent{0.3} A}
        \end{mdframed}}
    \end{flushright}
}

\setbeamercolor{background canvas}{bg=green!20}

\begin{frame}
    \Que<1->{What is \LaTeX{}?}

答案3

基于贡萨洛·梅迪纳答案，我做了一些调整：

标题

\usebeamerfont{title}
%\inserttitle\par % disabled
\begin{mdframed}[style=QueFrame]
    \inserttitle{\huge\color{blue} Questions and Answer}
\end{mdframed}

作者

\usebeamerfont{author}
    %\insertauthor % disabled
\begin{mdframed}[style=AnsFrame]
    \insertauthor{\Large\color{blue} Edy Wihardjo}
\end{mdframed}

和

%\title{The title} % disabled
%\author{The Author} % disabled

这就是我要的
