根据 Layout preview rendering problems in android studio(Android Studio 1.2)

Try changing your base application theme using below code - in res/values/styles.xml

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
</style>

OR

Also you can try Switching the preview's API level to lower one from the preview configuration

我认为还可以通过 Canary channel 将您的 Android Studio 更新到 2.0 Beta 2 可能会解决问题。

如果仍然不起作用，请尝试在设备上运行您的应用 - 此处的布局是否显示正确？

编辑:还要检查这些帖子中的解决方案:

在这篇文章中 Failed to load the LayoutLib: com.android.layoutlib.bridge.Bridge你会发现:

Possibly Classes With Identical names inside different projects.

I might know the issue. I just recreated a framework I made, and I called it number 2. A lot of the classes had the same name, and same method, inside packages of the same name. This seemed to really confuse the IDE and/or JRE.

I was able to sort of fix the problem, by making sure they weren't both being imported inside the same project! It is still giving me strange warnings, but it seems to be working correctly. What I would ultimately suggest if this is the case, would be to remove the duplicates from the project all together.
