Android：如何在另一个片段上更新微调器数据

Question

So I have 2 fragments Fragment1 and Fragment2. On an event in fragment 2 I would like to call the refreshSpinnerData method in Fragment1 to update the spinner in Fragment1. I'm a novice, but being that Fragment1 is an object I'd think that I could just put the following line in Fragment2. Fragment1.refreshSpinnerData();....but evidently that would just be too easy. So how do I go about doing this? Thanks for the help.

Try taking a look at Communicating with Other Fragments . In your case you would define the interface & callback in Fragment2, have your activity implement the interface, then find Fragment1 in your activity and call .refreshSpinnerData() on it.
