Android youtubePlayerFragmnet-无法创建用于播放youtube视频的片段

我需要在一个片段中播放youtube视频，即FragmentVideo。FragmentVideo是使用FragmentStatePagerAdapter创建的一个数量4

当我滚动到一个页面碎片视频应该显示视频形式的链接视频链接。 我真的在寻找如何完成这件事。大多数示例都是创建一个活动，但我需要在一个页面中使用它，其中相应的片段应该处理视频播放。 还基于片段状态暂停、恢复、onsavestateinstance视频播放应停止、恢复等

谁能帮帮我吗。 我已经有了所有的网络接入

我需要片段视频，应该播放youtube视频，播放/暂停等。。

如何实现这一点？

请查看mainactivity中的第278行。您是logcat，它清楚地告诉您链接278的问题代码在哪里是ifposition==3{fragment=new FragmentVideo；args.putinfragmentvideo.ARG_节号，位置+1；args.putStringVIDEOLINK，；}，其中fragment是fragment类型。它与创建其他片段的代码完全相同。我想我在FragmetnVideo的实现中弄乱了一些细节。还是我在这里遗漏了什么？
