在 Beamer 中使框架标题和块的宽度相同，尝试 2

Question

在我的一些Beamer 主题我使用的答案是在 Beamer 中使框架标题和块宽度相同。

然而现在一个问题已经提出，这由以下 MWE 证明：

\documentclass{beamer}
\setbeamertemplate{block begin}{
    \begin{beamercolorbox}[wd=\textwidth, ht=0.5cm, dp=0.2cm, leftskip=0.2cm]{block title}%
    \usebeamerfont*{block title}%
        {\rule[-0.4ex]{0mm}{2ex}\insertblocktitle}%
            \end{beamercolorbox}%
    {\ifbeamercolorempty[bg]{block body}{}{\nointerlineskip\vskip-0.5pt}}%
    \usebeamerfont{block body}%
    \begin{beamercolorbox}[wd=\textwidth, ht=0.5cm, dp=0.2cm, leftskip=0.2cm]{block body}%
        \ifbeamercolorempty[bg]{block body}{\vskip-.25ex}{\vskip-.75ex}\vbox{}%
}
\setbeamertemplate{block end}{
    \end{beamercolorbox}
    \vspace*{.25cm}
}
\setbeamertemplate{frametitle}{
\vspace*{0.3cm}
\begin{beamercolorbox}[wd=\textwidth, dp=0.3cm, ht=0.9cm, leftskip=0.2cm]{frametitle}
      \usebeamerfont{frametitle}\insertframetitle%
\end{beamercolorbox}
}
\setbeamercolor{block title}{bg=yellow}
\setbeamercolor{frametitle}{bg=yellow}

\begin{document}
\begin{frame}{Block}
This is text before the block.
\begin{block}{blocktitle} some text here 
\begin{itemize} 
\item This is an item in the block.
\end{itemize}
This is text after the itemize.
\end{block}
This is text after the block.
\end{frame}
\end{document}

如您所见，块标题、块主体和周围的文本都变得混乱和重叠。请帮我解决这个问题！同样重要的是，包含框架标题的彩色框和包含块标题的彩色框（以及包含块主体的彩色框，如果有的话）的宽度保持不变。

我确信这段代码有问题，但它似乎解决了眼前的问题。链接的解决方案为块设置了一个固定高度，与为块和框架标题设置的高度相同。您不需要逐项显示来显示问题 - 只需多行文本即可。

\documentclass{beamer}
\setbeamertemplate{block begin}{
  \vskip\baselineskip
  \begin{beamercolorbox}[wd=\textwidth, ht=0.5cm, dp=0.2cm, leftskip=0.2cm]{block title}%
    \usebeamerfont*{block title}%
    {\rule[-0.4ex]{0mm}{2ex}\insertblocktitle}%
  \end{beamercolorbox}%
  {\nointerlineskip\vskip-0.5pt}%
  \usebeamerfont{block body}%
  \begin{beamercolorbox}[wd=\textwidth, leftskip=0.2cm]{block body}%
    \vskip-.75ex\vbox{}%
  }
  \setbeamertemplate{block end}{
  \end{beamercolorbox}
  \vspace*{.25cm}
}
\setbeamertemplate{frametitle}{
  \vspace*{0.3cm}
  \begin{beamercolorbox}[wd=\textwidth, dp=0.3cm, ht=0.9cm, leftskip=0.2cm]{frametitle}
    \usebeamerfont{frametitle}\insertframetitle%
  \end{beamercolorbox}
}
\setbeamercolor{block title}{bg=yellow}
\setbeamercolor{frametitle}{bg=yellow}

\begin{document}
  \begin{frame}{Block}
    This is text before the block.

    \begin{block}{blocktitle} some text here
      \begin{itemize}
        \item This is an item in the block.
      \end{itemize}
      This is text after the itemize.
    \end{block}
    This is text after the block.
  \end{frame}
\end{document}
