Android Studio 3.0 的渲染問題

Question

我剛剛將 Android Studio 更新到 3.0，但我看不到 xml 文件的預覽。它說

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

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

Answer 1

將 Android Studio 更新到 3.0 后，我也遇到了顯示布局預覽的問題。 這就是幫助我的原因：

1. 轉到菜單“文件”
2. 選擇“使現金無效/重新啟動”
3. 在打開的窗口中單擊“無效並重新啟動”

希望它會有所幫助

Answer 2

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

用這個替換 fonts.xml 文件並重新啟動

 <?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

對我來說同樣的問題。

你以前有沒有編輯過 fonts.xml，（可能是韓文字體或編輯過的東西）

1. 打開“\\plugins\\android\\lib\\layoutlib\\data\\fonts\\fonts.xml”文件
2. 就我而言，474~475 行已損壞。 你必須修復

    '<family lan' 到 '</familyset>'

或重新安裝android studio 3.0

Answer 4

類似的事情發生在我身上，我覺得這是一個 Android Studio 錯誤？ 我不得不更改應用程序主題以使用Base.Theme.AppCompat而不僅僅是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 布局呈現良好。

源於此解決方案的一個問題是，我無法將父主題與 NoActionBar 一起使用，因此如果使用工具欄，我必須手動隱藏它：

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

Answer 5

我遇到了相同的渲染錯誤消息的相同問題。

經過數小時的研究並嘗試了這個和那個......在我按照以下指南完全卸載后，我最終重新安裝了Android Studio 3.0： 如何完全卸載Android Studio？

結果呢？ 它運作良好:)

Answer 6

我也有預覽 xml 布局的問題。 但現在它修復了。

因為您可能已經更新了 Android Studio 安裝目錄中的任何文件。

我的情況我更新了 font.xml 文件以預覽韓文字符目的(Android Studio\\plugins\\android\\lib\\layoutlib\\data\\fonts\\fonts.xml) 。

並且 Android Studio 3.0 已對該文件進行了更新以預覽韓文字符，因此安裝后我不再需要更新我的 font.xml。

我的解決方案是非常簡單的步驟：

• 卸載當前安裝的Android Studio 3.0
• 再次下載並安裝最新版本的 Android Studio 3.0。

卸載后安裝目錄中的所有內容都將被刪除，並在安裝下載文件時完全更新 Android Studio 3.0。

在這里查看我的評論以獲取詳細信息： Android Studio layout preview rendering issue after update

希望我的解決方案對您有所幫助。
