有没有办法摆脱它的子片段之一ViewPager适配器? [英] Is there a way to get the ViewPager adapter from one of its child fragments?
问题描述
从ListFragment我们可以称之为getListAdapter()从它的子片段中的一个访问列表的适配器。有没有从其子片段,类似getListAdapter()在ListFragment之一访问ViewPager适配器的简单和类原生的方式?
From a ListFragment we can call getListAdapter() to access the list's adapter from one of its child fragments. Is there a simple and class-native way to access the ViewPager adapter from one of its child fragments, similar to getListAdapter() in ListFragment?
如果没有的话,是正确的做法,包括它的子片段的每一个参考ViewPager适配器?
If there isn't, is the correct approach to include a reference to the ViewPager adapter on every one of its child fragments?

类。
从子片段来实现这个目的。
From child fragment class do this
((YourParentClass)getActivity()).mAdopter.WHAT_EVER_YOU_WANT_THIS_FOR;
