我在Android Studio中加载小部件时遇到问题
我不知道为什么会发生此问题，因此我打开了android studio并没有加载RecyclerView和其他小部件的视图，因为我清理了缓存也使用了Rebuild Project，但是问题仍然存在，不胜感激支持

仅基于依赖项，这些依赖项已正确添加且代码未移动，我的buildgradle以这种方式对其进行了结构化，其中我使用library.gradle按版本调用了这些库，这是实现的特定代码RecyclerView。
ext.versions = [
supportLib : '28.0.0'
]
def version = ext.versions
ext.library = [
support_recyclerview : 'com.android.support:recyclerview-v7:' + version.supportLib
]
