java - 二进制 XML 文件行 #52 : Binary XML file line #52: Error inflating class com. Askira.loopingviewpager.LoopingViewPager

Question

我正在尝试使用askira.loopingViewPager 设置菜单。但是，当我运行该应用程序时，它崩溃了，因为它无法从登录 Activity 转到 HomeActivity；​显示我粘贴在下面的错误...我想我的 XML 文件中可能仍然有一些来自旧布局的元素，但我找不到一些？!我仍然认为问题出在 XML 文件中。我可以做什么来解决这个问题？代码编译良好且没有错误，Gradle 已更新到最新版本。如果您需要更多信息，请告诉我。谢谢。

您拼错了软件包名称:它是 com.askira，而不是 com.askira - 您缺少一个 s。

<com.asksira.loopingviewpager.LoopingViewPager
        android:id="@+id/viewpager"
