更新后的Android Studio布局预览渲染问题 [英] Android Studio layout preview rendering issue after update
本文介绍了更新后的Android Studio布局预览渲染问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我很困惑.在Android Studio 3.0的最新更新之前，它运行良好.
I am so confused. It worked fine just before the most recent update to Android Studio 3.0.
我所有的xml文件都存在相同的呈现问题.我什么都看不到.
All of my xml files have the same rendering issue. I cannot see anything.
它说:
无法初始化类android.graphics.Typeface
" Could not initialize class android.graphics.Typeface
渲染期间引发异常:无法初始化类android.graphics.Typeface
Exception raised during rendering: Could not initialize class android.graphics.Typeface
提示:尝试刷新布局. "
Tip: Try to refresh the layout. "
无论我尝试刷新多少次，它都无法正常工作. 我重新启动了Android Studio，但仍然无法正常工作.
No matter how many times I try to refresh this thing, it just won't work. I restarted Android Studio, but it still won't work.
我什至不知道从哪里开始解决这个问题，因为我以前从未见过这样的问题.我用谷歌搜索，但是找不到任何有用的信息.
I have no idea where to even start with fixing this problem, because I've never seen such problem before. I googled it, but I couldn't find anything helpful.
我需要帮助.请救救我！
I need help. Please save me!
推荐答案
C:\ Program Files \ Android \ Android Studio \ plugins \ android \ lib \ layoutlib \ data \ fonts
C:\Program Files\Android\Android Studio\plugins\android\lib\layoutlib\data\fonts
以此替换fonts.xml文件并重新启动
Replace the fonts.xml file with this and restart
<?xml version="1.0" encoding="utf-8"?>
<!--
WARNING: Parsing of this file by third-party apps is not supported. The
file, and the font files it refers to, will be renamed and/or moved out
from their respective location in the next Android release, and/or the
format or syntax of the file may change significantly. You must not
parse this file for information about system fonts. Instead, you must
call android.text.FontManager#getSystemFonts(). For example, it can be
called as context.getSystemService(FontManager.class).getSystemFonts().
Note that the returned FontConfig includes data on all the defined font
families and all the details about weight, style, etc. It also provides
an open file descriptor to each font file. Note that callers of the API
should ensure they close the given file descriptors once they are done
using them.
In this file, all fonts without names are added to the default list.
Fonts are chosen based on a match: full BCP-47 language tag including
script, then just language, and finally order (the first font containing
the glyph).
Order of appearance is also the tiebreaker for weight matching. This is
the reason why the 900 weights of Roboto precede the 700 weights - we
prefer the former when an 800 weight is requested. Since bold spans
effectively add 300 to the weight, this ensures that 900 is the bold
paired with the 500 weight, ensuring adequate contrast.
