Question

this is a rough idea of what my program looks like

MainTabHost Activity (startup)

===> Tab1 (activity1.java)

         public void refresh();

===> Tab2 (activity2.java)

I have a refresh function on activity1 that repaints a listview. If I switch to Tab2, then switch back to Tab1, I need an event to call that function.

All the examples for OnTabChangeListener involve defining the event at the startup activity.. however at that level, I’m not sure how to invoke a function in activity1/2 ?

thanks in advance

Answer 1

I have not used TabActivity but I would assume that onResume() gets called when you switch to a new activity as per the android activity lifecycle. Could you do your refresh() in the onResume() of your tab1 activity?
