Question

I\'m developing for android 3+

In my action bar i have a drop-down list(see how to hide/unhide the actionbar list on android 3? for the dropdown i intend). The probl

Answer 1

Method onNavigationItemSelected(int itemPosition, long itemId) will be called anyway by the action bar.

What you may want to do is to tell action bar what itemPosition it should pass to the method on the first call. (In other words, to tell action bar what navigation item should be set after activity is created). Here is the code:

mActionBarMenuSpinnerAdapter = ...;
mActionBar = getActionBar();
mActionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
mActionBar.setListNavigationCallbacks(mActionBarMenuSpinnerAdapter, this);
mActionBar.setSelectedNavigationItem(###your_default_navigation_item_here###);

After doing this you can solve your problem by applying changes in the onNavigationItemSelected(int itemPosition, long itemId) if only itemPosition is different.
