大家好我现在正在我的应用中集成youtube API，我必须从API解析视频ID列表，然后当我们点击视频时，我必须在列表视图中显示视频播放直到此工作正常
当用户选择横向模式的全屏模式后，我得到一些错误

这是我的片段
布局文件是
<merge xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment

当我尝试以全屏模式播放视频时，我收到以下错误
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
请指导我如何进一步行动。
提前致谢。
答案 0 :(得分：2)
问题是你正在用片段内的片段来扩充布局。你不能这样做，所以你得到了错误。但是你可以动态地添加它们。
注意：当布局包含a时，您无法将布局扩展为片段。只有动态添加到片段时才支持嵌套片段。
