Refreshing Activity When Dialog Dismisses

Question

Actually in my list activity,when user taps on any item ,a dialog box is opened with two options of delete and cancel.When user select delete button the dialog dismisses with deleting value in database.And the old list activity comes in foreground with old values.Though it is deleted it is showing in listview.Is there a way to show the refreshed list.If yes,then How?

Answer 1

You can override activity method onWindowFocusChanged(boolean hasFocus) and track the state of your activity.

Normally, if some alert dialog is shown above your activity, the activity does not get onPause() and onResume() events. But it loses focus on alert dialog shown and gains it when it dismisses.

In your case you can refresh your data in onWindowFocusChanged() if hasFocus is true.
