我想换个思路:为什么要将活动用作选项卡?您所做的只是增加开销和复杂性.只需对选项卡使用视图即可.

I'd flip it around: why would you want to use activities as tabs? All you do is add overhead and complexity. Just use Views for the tabs.

如果您有一些东西必须既是选项卡又是单独的独立活动，请重用视图.

If you have something that just has to be both a tab and a separate standalone activity, reuse the View.
