不能再查看JetPack组成预览。无法实例化一个或多个类（ComposeViewAdapter）

Question

最近，我有一个错误，可以防止任何JetPack组成的预览显示如下：

Failed to instantiate one or more classes
The following classes could not be instantiated:
     -androidx.compose.ui.tooling.ComposeViewAdapter(Open Class, Show Exception, Clear Cache)

if this is an unexpected error you can also try to build the project, then manually refresh the layout

我尝试清除缓存，重建项目，按建议清洁项目，但没有任何帮助。我在Android Studio Bumblebee 2021.2.1补丁3以及Chipmunk 2021.2.1 beta 4中都遇到了相同的问题

。没有任何帮助。

implementation 'androidx.core:core-ktx:1.7.0'
implementation "androidx.compose.ui:ui:1.1.1"
implementation "androidx.compose.material:material:1.1.1"
implementation "androidx.compose.ui:ui-tooling-preview:1.1.1"
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.3.1'
implementation 'androidx.activity:activity-compose:1.1.1'

我认为这里有几个问题问类似的事情，但是它们都很老，并且使用了长期过时的作曲和Android Studio，因此它们并不是很有帮助。

这是一个已知的错误： https://issuetracker.google.google.com/issues/issues/22777777363

当前正在处理修复程序，但已经有一个解决方法：将这些依赖项添加到使用Compose Preview的每个模块中：

debugImplementation "androidx.customview:customview:1.2.0-alpha01"
debugImplementation "androidx.customview:customview-poolingcontainer:1.0.0-alpha01"

如果您有一个共同的Core/base/us/UI模块，则可以在此处添加并使用api 而不是实现避免将其添加到每个模块中：

debugApi "androidx.customview:customview:1.2.0-alpha01"
debugApi "androidx.customview:customview-poolingcontainer:1.0.0-alpha01"

伪像释放参考

Answer 2

我正在迁移一个简单的项目来撰写，并且面临着这个问题。然后我意识到我忘记了添加“ androidx.compose.ui：ui-tooling：1.1.1”

这些都是我的JetPack组成的依赖性。添加最后一行可以解决问题。花了20分钟才意识到这一点...

implementation("androidx.compose.ui:ui:1.1.1")
implementation("androidx.compose.material:material:1.1.1")
implementation("androidx.compose.ui:ui-tooling-preview:1.1.1")
debugImplementation("androidx.compose.ui:ui-tooling:1.1.1")
