onFragmentResult和RingtoneManager糟糕的爱情故事

Question

我想做什么，

我得到了一个包含3个片段的FragmentActivity，这些片段是通过一个ViewPager实现的.现在我想在RingtoneManager上显示铃声或Notification音调。为此，我创建了一个方法，它工作得很好。现在，当我想从RingtoneManger获得数据时，我选择一个音调，然后按OK键。在我的onFragmentResult()中什么都不会发生。

问题

我需要改变什么，才能从RingtoneManager中得到结果？

该守则如下：

诚挚的问候

什么是onFragmentResult.？如果两个片段都在同一个片段中，我认为它适用于onActivityResult...instead。
