我正在用波斯语写一本书（其方向是从右到左），我希望页码像下面的代码一样显示：
\documentclass[12pt,twoside]{book}
\usepackage{tikz}
\usepackage{lipsum}
\usepackage{fancyhdr}
%\usepackage{xepersian} % If this enables problem occurs
%\settextfont{Adobe Arabic} % Or \settextfont{Yas}
\fancypagestyle{myfancy}{%
\fancyhf{}%
\fancyfoot[OL]{%
\begin{tikzpicture}[overlay,baseline={(0,0)},anchor=center]
\node[
rectangle,
outer sep=0pt,
text=white,
fill = black!30,
draw = black!20,
anchor=west,
]
(pageno)
{\phantom\thepage};
\draw[
fill = black!30,
draw = black!20,
]
([xshift=-\oddsidemargin-1in]pageno.north west)
rectangle
(pageno.south east);
\node[
anchor=east,
font=\color{white}
]
at (pageno.east)
{\thepage};
\end{tikzpicture}%
}%
\fancyfoot[ER]{%
\begin{tikzpicture}[overlay,baseline={(0,0)},anchor=east]
\node[
rectangle,
outer sep=0pt,
text=white,
anchor=east,

(pageno)
{\phantom{\thepage}};
\draw[
fill = black!30,
draw = black!20,
]
([xshift=\paperwidth-\textwidth-\oddsidemargin-1in]pageno.north west)
rectangle
(pageno.south west);
\node[
anchor=west,
font=\color{white}
]
at (pageno.west)
{\thepage};
\end{tikzpicture}%
}%
\renewcommand{\headrulewidth}{0pt}%
\renewcommand{\footrulewidth}{0pt}%
}%
%% without the following the chapter pages won't have fancy page style

代码在没有xepersian包的情况下编译完美，但使用此包后，偶数页码不合适。有人知道这个吗？

第二个答案中的代码产生了这样的结果：
答案1
由于从左到右变为从右到左，Tik是对东和西的解释不同。因此，您需要重新配置 tikzpicture 部分中的锚点。
我稍微简化了您的代码，east并west在适当的地方进行了相应的切换，以便现在的代码适合从右到左的排版：
\documentclass[12pt,twoside]{book}
\usepackage{tikz}
\usepackage{lipsum}
\usepackage{fancyhdr}
\usepackage{xepersian}
\settextfont{Amiri} % I didn't have the other fonts
\fancypagestyle{myfancy}{%
\fancyhf{}%
\fancyfoot[OL]{%
\begin{tikzpicture}[overlay,baseline={(0,0)}]
\node[
rectangle,
outer sep=0pt,
text=white,
fill=black!30,
draw=black!20,
anchor=east,
]
(pageno)
{\thepage};
\draw[
fill=black!30,
draw=black!20,
]
([xshift=\oddsidemargin+1in]pageno.north east)
rectangle
(pageno.south east);
\end{tikzpicture}%
}%
\fancyfoot[ER]{%
\begin{tikzpicture}[overlay,baseline={(0,0)}]
\node[
rectangle,
outer sep=0pt,
text=white,
fill=black!30,
draw=black!20,
anchor=west,
]
(pageno)
{\thepage};
\draw[
fill=black!30,
draw=black!20,
]
([xshift=-\oddsidemargin-1in]pageno.north west)
rectangle
(pageno.south west);
\end{tikzpicture}%
}%
\renewcommand{\headrulewidth}{0pt}%
\renewcommand{\footrulewidth}{0pt}%
}
\begin{document}
\pagestyle{myfancy}
\chapter{تست ۱}
\lipsum[1-5]
\section{تست ۲}
\lipsum[1-5]
\end{document}
当然，这意味着如果您xepersian再次注释该包，该解决方案将再次不起作用。

第二次编辑
不知何故，所使用的软件包的不同版本在解释东方和西方方面表现不同。上述答案目前适用于我用于测试的 Overleaf。
以下内容应适用于最新的软件包（截至 2019 年 2 月 5 日）：
