如何解决这个问题,尽管我将相同的代码放在服务依赖项的其他项目中 com.android.support:support-v4:21.0.3
并且看起来不错
现在我正在使用 com.android.support:appcompat-v7:25.3.1
com.example.com.kada.view.pzv.PullToZoomScrollViewEx
不是 com.example.com.kada.view.pzv.PullToZoomListViewEx
的子 class,因此无法转换。这就是异常消息明确试图告诉您的内容。
您的布局使用 PullToZoomScrollViewEx
,但您将 findViewById()
returns 转换为 PullToZoomListViewEx
。修复转换以使用正确的 class 或确保 class 具有相同的祖先。
此外,如果您切换到使用 SDK 26 进行编译,请参阅 ,但是如果您使用错误 classes.
,这仍然会抛出异常
