3 个解决方案

#1

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

尝试使用下面的代码更改基本应用程序主题 - 在res / values / styles.xml中

<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

您也可以尝试将预览的API级别切换为预览配置中的较低级别

#2

You can also update Gradle to version 1.2.3 as explained here: https://code.google.com/p/android/issues/detail?id=171417

您还可以按照此处的说明将Gradle更新为1.2.3版:https://code.google.com/p/android/issues/detail?id = 171417

Apparently this was a bug on version 1.2.2 of Gradle and from the next version of Android studio Gradle 1.2.3 will be the default on new projects.

显然,这是Gradle版本1.2.2的一个错误,从下一个版本的Android Studio Gradle 1.2.3将是新项目的默认设置。

At least it worked for.

至少它起作用了。

While Base.Theme.AppCompat.... is the superclass of Theme.AppCompat.... anyway, I prefer the fix using the new version of Gradle.

虽然Base.Theme.AppCompat ....是Theme.AppCompat的超类....无论如何,我更喜欢使用新版Gradle的修复。

Worked for me, hope it works for you.

为我工作,希望它适合你。

Also I had to Clean and Rebuild the Project.

我还必须清理并重建项目。

#3

The easiest way would be to change the theme of the application by clicking AppTheme.

最简单的方法是通过单击AppTheme来更改应用程序的主题。

This does not need to change anything in the code.

这不需要在代码中更改任何内容。
