如何使用选项卡视图片段将RecyclerView中的数据绑定

Question

我的应用程序中有3个Tab。假设第一个是A，B和C.我的MainActivity声明并设置一个Tab Listener，我的每个Tab再次有3个Activity。我的问题是，在标签A中我用Volley加载数据。在标签B中我也加载不同的数据。但有时我的RecyclerView，数据很奇怪（标签B或标签B中显示的标签B中的数据成功加载数据，但标签A没有显示任何内容）。我在每个活动选项卡中加载数据，如下面的代码。我做错了吗？或者我应该加载MainActivity中的所有数据？任何答案对我都有帮助。

之前谢谢

编辑：

这低于我的标签

在第一个标签中，应该显示带有文字Popularity的文字视图，但是在App首次打开时始终显示Top Rated内容
