问题

  • Crypto Tweets * 示例应用root分支为三个应用模块app、app-rx和app-simple模块实现了 * Android View Binding *。所有三个模块都按预期运行。但是，在app和app-rx模块中，Unresolved reference存在Lint错误。

例如，在app和app-rx模块中，fragment_feed.xml是未解析的，而在app-simple中，引用显示没有导入错误。

有相同的问题，添加

implementation "androidx.compose.ui:ui-viewbinding:1.2.1"

到module Gradle文件，import androidx.compose.ui.viewinterop.AndroidViewBinding上的错误消失

它肯定会晚，但只是以防万一其他人也面临同样的问题，这是我如何解决它：
在我的具体案例中，我在模块Gradle文件中有下一个实现：

implementation "androidx.core:core-ktx:+"

在更改为Kotlin特定版本后，如下所示：

implementation "androidx.core:core-ktx:1.8.0"

“未解析的引用”构建错误已消失。
