Android 无法使用片段访问布局元素

几周前我发布了一个类似的问题，但现在我的问题有点不同了。这基本上是一个重新发布，但有更新信息。这是我的主要活动。我的微调器过去是空的，但现在我似乎有它初始化，但没有填充。我花了相当长的时间在这个问题上，研究了很多在线帖子的解决方案，并尝试了一些修复。到目前为止，一切都不起作用。有什么想法吗

此外，请忽略日期创建/排序代码。这是非常混乱，我已经有了一个更整洁的方式来做它，但不会实现它，直到我有这个部分修复

注意：id在我的布局中都是正确的，我非常确定这不是问题所在

是的，如果你能发布相关的代码那就太好了…@tyczj你是什么意思？所有相关代码都在那里。
