java - AndroidBoostrap预览模式: Font not properly registered

Question

我正在使用 AndroidBootstrap 2.0.0 在我的 Android 应用程序中实现按钮和图标，但在 AndroidStudio 中，由于渲染问题，我总是遇到恼人的异常图形布局编辑器。此外，该按钮未显示在图形布局编辑器中，但当我在设备上运行该应用程序时，按钮会显示并正常工作。所以这个错误只发生在预览模式下。

这是异常(exception):

我在 list 中添加了 AndroidBootstrap 作为依赖项，将 TypefaceProvider.registerDefaultIconSets(); 添加到我的 Application 类中，并导入了 fontawesome-webfont-v440.ttf 字体文件复制到我的项目 assets/fonts 文件夹中。

我错过了什么吗？ 感谢您的帮助。

不要 panic ，一切都正确。 :)

这是库中的一个错误，图标应该在编辑模式下隐藏。我已将此问题提交给 Jamie@BeardedHen 并在 GitHub 存储库下进行。

这个问题将在 2.0.1 版本中得到解决，我已经提出了一个 fork 请求，将 View.isInEditMode() 添加到实例化方法中。
