搜索过滤器在MainActivity中暗示不同的三个Fragment

Question

我的问题与WhatsApp搜索功能完全相关。 我有MainActivity：在该活动中，我有3个片段： 片段首页 片段办公室 片段其他

对于所有片段，我都有单个适配器类。 我将所有数据加载到全部3个片段中，但仅在UI中显示，这取决于类型home / office / other。

现在，我想暗示搜索过滤器。显然，我在MainActivity上做了。但是现在的问题是，如果用户从主页片段中搜索，它应该仅从主页片段中搜索。

请注意：所有三个片段的数据均不同。而且我在MainActivity中什么也不做。
