Android refresh list on resume

The swipe-to-refresh user interface pattern is implemented entirely within the SwipeRefreshLayout widget, which detects the vertical swipe, displays a distinctive progress bar, and triggers callback methods in your app. You enable this behavior by adding the widget to your layout file as the parent of a ListView or GridView , and implementing the refresh behavior that gets invoked when the user swipes. This lesson shows you how to add the widget to an existing layout. It also shows you how to add a refresh action to the action bar overflow area, so that users who may be unable to use the swipe gesture can trigger a manual update with an external device. The following example demonstrates how to add the SwipeRefreshLayout widget to an existing layout file containing a ListView :. However, explicitly declaring the ListView in this way supersedes the default ListFragment view structure.

I can use this intent to refresh the activity currently:. But I can't figure out how to properly use the onResume function to refresh my act A after going back to it. This works even if you terminate ActivityB by the press of the back button.

    The sometimes very restrictive and challenging assignment criteria helped me to step out of my comfort zone and learn, that yes indeed, I can write a believable and engaging story snippet, even if I do not at all identify with the framework I am required to follow.
