Android Studio 3.0布局编辑器中的渲染错误 [英] Render error in Android Studio 3.0 Layout Editor
问题描述
我刚刚开始学习Kotlin进行android开发，并开始了一个空项目并添加了一个活动.如Kotlin文档中所述，我已经添加了必需的gradle依赖项.默认情况下，MainActivity的xml文件仅包含一个TextView.但是，当我尝试在布局编辑器中预览xml时，它显示了渲染错误"
I just started learning Kotlin for android development and started an empty project and added an activity. I have added the required gradle dependencies as said in Kotlin docs. By default the xml file of MainActivity contains only a TextView. But when I try to preview the xml in Layout Editor it shows a "Render Error"
Render problem
Failed to load AppCompat ActionBar with unknown error.
我也得到这个
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.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)
- android.support.v7.widget.ActionBarOverlayLayout (Open Class, Show Exception, Clear Cache)
Exception Details java.lang.ClassNotFoundException: android.support.v4.view.TintableBackgroundView
我尝试过手动重建项目并刷新布局.但是似乎没有任何作用.
I have tried rebuilding the project and refreshing layout manually. But nothing seems to work.
那我该怎么办?我正在将Kotlin与Android Studio 3.0 Canary 2配合使用
So what do I do? I'm using Android Studio 3.0 Canary 2 with Kotlin
已编辑
我已经取得了一些进展.我发现我的AppCompat主题均无效.
I have made some progress. I have found that none of my AppCompat Themes are working.
推荐答案
好吧，检查一下gradle，您是否在app/build.gradle文件中添加了support:appcompat依赖项?也是appcompat:design依赖项
Well, check your gradle , have you added support:appcompat dependency in app/build.gradle file ? also appcompat:design dependency
