你好每一个我试图将视图转换为片段，但它显示错误的错误转换视图片段请给我解决方案我怎么能做到这一点。我在listview的baseadapter中使用它
谢谢，我的代码在这里
在pages.add（）;
中出现错误package okay.adapters;

View和Fragment个对象无法转换为另一个对象，因为它们具有非常不同的超类，也不是接口。如果您不明白为什么我建议继续阅读http://developer.android.com/develop/index.html。

在片段中，添加class ="...."。
答案 2 :(得分：0)
您不能执行此操作（将视图投射到片段），但是如果您需要获取添加的片段，请说您使用支持片段管理器添加了片段，然后可以通过TAG从UI中获取当前片段
