Android Studio布局编辑器主题不'；不匹配装置

希望这是一个很好的简单的一个，但它目前的UI设计更吸比平常

当我在Android Studio的布局编辑器中查看片段的XML文件时，它显示如下：

但是，当我在设备/仿真器上查看时，它正确地显示如下：

我在编辑器顶部选择了我的自定义主题，因此理论上应该使用它来呈现UI。我唯一的想法是，大多数无法渲染的组件都是

com.google.android.material

的一部分，AS没有正确处理这些组件

有没有办法解决这个问题，或者说这只是使用自定义组件的乐趣

谢谢

Path.op() not supported

---

您必须将您的材料实现替换为

implementation'com.google.android.material:material:1.2.0-alpha02'

---

Path.op（）在比alpa02更新的版本上不起作用-这可能是一个bug，或者他们刚刚弃用了它。

您没有类似于

渲染失败

的警告吗？Android studio有时无法正确渲染视图-通常会重新启动整个IDE。其次，你的设备和模拟器之间的API有什么不同？（如果有的话）它可以在设备和模拟器上工作（并且它们是相同的版本）。有一些渲染错误（我已经用它们更新了问题）。我尝试过重新启动并使缓存无效，但没有任何帮助。感谢您的帮助解决Path.op（）错误的一个方法是将

implementation'com.google.android.material:material:1.2.0-alpha02'

添加到您的依赖项中（如果您已经有了该实现，仍然-用该alpa02替换您的实现）嗯，这已经解决了（我在alpha04上）。所以我猜这只是他们在某个阶段打破的东西？谢谢你的帮助是的，这可能是一个bug或者他们刚刚删除了对它的支持。我会将此作为答案发布，因此请将其标记为正确答案。干杯感谢您的帮助，当您可以看到元素时，UI设计会稍微容易一些：）
