我猜问题出在 OnInfoListener 上，因为当我删除它时一切正常。
【问题讨论】：
请发布完整的堆栈跟踪和CustomVideoView 类。
@MikeM。我更新了我的问题
ClassNotFoundException: com.webtv.CustomVideoView。你确定它不应该是com.tibo.webtv.CustomVideoView？
我用xxxx隐藏包名
是的，我收集到了，但你的堆栈跟踪显示com.webtv.CustomVideoView。如果您最近更改了它（清理并）重建您的项目。
【参考方案1】：
问题在于包名。将您在 xml 中使用的完整限定类名称与您的类定义进行交叉检查。
简而言之，当您按下 ctrl+鼠标左键时，您应该被重定向到类定义。
应该是com.packagename.yourCustomclassName
【讨论】：
当我按下 CTRL+鼠标左键时，它会将我重定向到类定义，所以包名是正确的【参考方案2】：就我而言，我已经删除了该属性 android:background，从那时起我没有收到任何 inflate 异常。
