I have 2 activities in my application. In activity1, I set some configuration and I modify the state of some component (ex: set button state disabled). And I navigate to activity2. In activity2 I do some stuff and at end, I finish this activity and come back to activity1. But In activity1, my components state are the same when I leave this activity. How to reset the components state with valuesdeclared in XML file (layout) ?
