从活动通话片段事件

问题描述

所以，我得到了我的片段，该事件传递给活动，所以我怎么让它如此轮流活动，通知B片段做一些事情。我想B片段来填充自定义列表时，片段A有一个列表项点击。因此，它发送事件的活动，现在我怎么活动在B片段称之为事件？

So, I got the event in my fragment to pass to the activity, so how do I make it so the activity in turns, notifies fragment B to do something. I want to fragment B to populate a custom list when fragment A has a list item clicked on. So, it sends the event to the activity, now how do I get the activity to call events in fragment B?

推荐答案

这样做会是这样在你活动的一种方式：

One way to do it would be like this in your activity:

FragmentB fragmentB = (FragmentB)getFragmentManager().findFragmentById(R.id.fragmentBId);
fragmentB.performSomeTask();

这是当然，假设你有FragmentB公开通俗易懂的方法称为performSomeTask（）的;

This is of course assuming that you have a publicly accessibly method in FragmentB called performSomeTask();
