Android Question Menu "button"

[migrec]

Hey, I just wonder if this (marked in red) can be done:

When you click in the red marked area a click event is triggered, in the action/toolbar. note the thing that points up and down, it chages

Would be nice if anyone knew how to do this!

If you are using the holo theme then you can change the action bar icon with StdActionBar library.
You can handle the Activity_ActionBarHomeClick event and change it there. The icon will appear left to the title.

To set the holo theme:

SetApplicationAttribute(android:theme, "@android:style/Theme.Holo")
