Android Studio 3.0 的渲染问题

Question

我刚刚将 Android Studio 更新到 3.0，但我看不到 xml 文件的预览。它说

Exception raised during rendering: Could not initialize class android.graphics.Typeface

java.lang.NoClassDefFoundError: Could not initialize class android.graphics.Typeface

Answer 1

将 Android Studio 更新到 3.0 后，我也遇到了显示布局预览的问题。 这就是帮助我的原因：

1. 转到菜单“文件”
2. 选择“使现金无效/重新启动”
3. 在打开的窗口中单击“无效并重新启动”

希望它会有所帮助

Answer 2

C:\\Program Files\\Android\\Android Studio\\plugins\\android\\lib\\layoutlib\\data\\fonts

用这个替换 fonts.xml 文件并重新启动

 <?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. --> <familyset version="22"> <!-- first font is default

Answer 3

对我来说同样的问题。

你以前有没有编辑过 fonts.xml，（可能是韩文字体或编辑过的东西）

1. 打开“\\plugins\\android\\lib\\layoutlib\\data\\fonts\\fonts.xml”文件
2. 就我而言，474~475 行已损坏。 你必须修复

    '<family lan' 到 '</familyset>'

或重新安装android studio 3.0

Answer 4

类似的事情发生在我身上，我觉得这是一个 Android Studio 错误？ 我不得不更改应用程序主题以使用Base.Theme.AppCompat而不仅仅是Theme.AppCompat 。

 <!-- Base application theme. -->
    <style name="AppTheme" parent="Base.Theme.AppCompat.Light">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

在此之后，xml 布局呈现良好。

源于此解决方案的一个问题是，我无法将父主题与 NoActionBar 一起使用，因此如果使用工具栏，我必须手动隐藏它：

<item name="windowActionBar">false</item>

Answer 5

我遇到了相同的渲染错误消息的相同问题。

经过数小时的研究并尝试了这个和那个......在我按照以下指南完全卸载后，我最终重新安装了Android Studio 3.0： 如何完全卸载Android Studio？

结果呢？ 它运作良好:)

Answer 6

我也有预览 xml 布局的问题。 但现在它修复了。

因为您可能已经更新了 Android Studio 安装目录中的任何文件。

我的情况我更新了 font.xml 文件以预览韩文字符目的(Android Studio\\plugins\\android\\lib\\layoutlib\\data\\fonts\\fonts.xml) 。

并且 Android Studio 3.0 已对该文件进行了更新以预览韩文字符，因此安装后我不再需要更新我的 font.xml。

我的解决方案是非常简单的步骤：

• 卸载当前安装的Android Studio 3.0
• 再次下载并安装最新版本的 Android Studio 3.0。

卸载后安装目录中的所有内容都将被删除，并在安装下载文件时完全更新 Android Studio 3.0。

在这里查看我的评论以获取详细信息： Android Studio layout preview rendering issue after update

希望我的解决方案对您有所帮助。
