大家好，我现在正在我的应用程序中集成youtube API，我必须解析API的视频id列表，然后当我们点击它时，我必须在列表视图中显示视频，视频必须播放直到这一切正常
之后，当用户选择全屏模式，即横向模式时，我会收到一些错误

这是我的碎片
布局文件是
<merge xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/container"

当我尝试在全屏模式下播放视频时，我得到以下错误
java.lang.IllegalArgumentException: Binary XML file line #42: Duplicate id 0x7f0d0117, tag null, or parent id 0x7f0d0115 with another fragment for com.mycristoparish.Fragments.VideoGallery$VideoFragment
请指导我怎样才能更进一步。
提前谢谢。
问题是您正在用片段中的片段来膨胀布局。你做不到，所以你得到了错误。但是，您可以动态添加它们。
更多详细信息
注意：当布局包含时，不能将该布局膨胀为片段。只有在动态添加到片段时才支持嵌套片段。
