我很生气地从here
编译Yalintis的图书馆我每次都会收到错误。错误发生在，
com.yalantis.dracoagain.FriendsActivity $ FriendsAdapter.getPage（FriendsActivity.java:60）`
并且MainActivity的第60行是
holder.infoPage = getLayoutInflater().inflate(R.layout.friends_info, parent, false);
所以这意味着，它甚至无法设置视图。我确实在gradle（模块级别）中导入了库。
我真的想知道如何修复它。我遵循git中提到的每一步。
这是完整的错误logcat -
