【问题描述】：
我已经开始了一个新项目，但我不断收到以下渲染器错误：
Rendering failed with a known bug. Please try a rebuild. The following classes could not be instantiated:
- android.support.v7.widget.AppCompatImageView (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.ActionBarContainer (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.Toolbar (Open Class, Show Exception, Clear Cache)
- android.support.constraint.ConstraintLayout (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.AppCompatTextView (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.ActionBarContextView (Open Class, Show Exception, Clear Cache)
- android.support.v7.app.WindowDecorActionBar (Open Class, Show Exception, Clear Cache)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE. If this is an unexpected error you can also try to build the project, then manually refresh the layout.

我也在使用最新的支持库和最新版本的 gradle 构建工具。我似乎无法让渲染器工作。

@XH6user 我正在使用 Android Studio 2.3.3

您是否尝试将 .Base 添加到主题？看起来它适用于很多人。
