android - Toast.makeText 给出 "Error inflating class Textview"异常

Question

我的应用程序中的每个 Toast.makeText 都会给我一个类似于此的堆栈跟踪:

这些是导致它的一些示例 Toast.makeText 调用

Toast.makeText(ReportActivity.this, "Reported for "+ reportType, Toast.LENGTH_SHORT).show();

Toast.makeText(this, R.string.network_unavailable, Toast.LENGTH_SHORT).show();

这一切都始于我们升级 Gradle 库并开始使用这些版本

compileSdkVersion 27
buildToolsVersion '27.0.1'

该错误显然是在 API 25 及更低版本上使用支持库 26+ 时出现的，据推测已在 Oreo 中修复。

在我的案例中，解决方法是更改​​在我的默认主题中定义的 fontFamily，方法是将 sans-serif-light 提取到一个字符串资源，这是从这里开始的:

<style name="AppCompatTheme" parent="android:...">
  <item name="fontFamily">sans-serif-light</item>
</style>

对此:

   <style name="AppCompatTheme" parent="android:...">
     <item name="fontFamily">@string/default_font</item>
   </style>

在我的 strings.xml 中:

   <string name="default_font" translatable="false">sans-serif-light</string>
