How to get notified when when action items get into the overflow menu?

Question

When you put a lot of action items on the action bar, some of them get to be inserted into the overflow menu, or become available by clicking on the menu button (if present).

Is there a way to be notified when this occurs? Maybe even know which items got to be into the overflow menu (or available via the menu button) ?

Again, I don't ask how to put items there and I don't need to get explanation about how to define action items. I ask how to know when and which items get to be there.

Answer 1

You cannot decide which item to be into Action overflow menu but you can decide which to be shown always on Action bar.

You can also use "always" to declare that an item always appear as an action button. However, you should not force an item to appear in the action bar this way. Doing so can create layout problems on devices with a narrow screen. It's best to instead use "ifRoom" to request that an item appear in the action bar, but allow the system to move it into the overflow when there's not enough room. However, it might be necessary to use this value if the item includes an action view that cannot be collapsed and must always be visible to provide access to a critical feature.
