How to add dropdown menu to ActionBar in Android project?

Question

I had been developing Android applications, but I don't know much about 4+ versions of Android well. Therefore, please help me - I have made Android application with tabs for navigation:

final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

But I also need to add dropdown menu to ActionBar for other goals. Can I do it? Please, if it's possible, give me an example. Thank you in advance.

You can use something called an android spinner. It looks like this:

You can customize it in many ways to suit your apps design too.

Here's a great tutorial by Google on how to use these:

http://developer.android.com/guide/topics/ui/controls/spinner.html

If you want to add this to an action bar, you can do it via a spinner adapter as detailed here: http://developer.android.com/guide/topics/ui/actionbar.html#Dropdown

If you want to add icons to do certain actions, then you can see this: http://developer.android.com/guide/topics/ui/actionbar.html#ActionItems

If you want to do certain actions in the bar itself (like search in the google search app) then see this: http://developer.android.com/guide/topics/ui/actionbar.html#ActionView

If you want to add navigation tabs, then see this: http://developer.android.com/guide/topics/ui/actionbar.html#Tabs
