我正在尝试在 BrowseFragment 之外重用 AndroidTV Leanback 提供的 RowsFragment，以在不同的布局上具有类似的行交互外观，但我遇到了无法调试的 XML 膨胀错误和解决。

实现本身与此处实现的类似：https ://medium.com/building-for-android-tv : //medium.com/building-for-android-tv，但在博客中，他在 BrowseFragment 中替换了相同类型的不同片段。我的方法有什么根本错误吗？如果是这样，为什么？我一直在阅读 Leanback 资源，但找不到任何我能理解的东西（尽管它是一个大型图书馆），可以将片段耦合到那种程度。

确保您的ChangePicActivity在 AndroidManifest.xml 中有正确的主题

将android:theme="@style/Theme.Leanback"添加到相关活动标签。像这样

 <activity
        android:name=".ChangePicActivity"
        android:theme="@style/Theme.Leanback"
 >
