问题 I have an application that has three fragments: Records, Chart, and PieChart. These fragments are stored in a ViewPager in a single activity and the user can swipe between them. The Records fragment has a table where the user can enter data. When the user enters data, the other two fragments need to be updated because they reference this data.

问题 Is there any way for me to invoke a callback when the user swipes from one pane to the next? As far as my experimentation has revealed, the present (primary) pane/fragment as well as the adjacent two (to the left and right) are all 'resumed', so none of the regular fragment lifecycle callbacks are invoked.
