We are working on an Android application for industrial uses. We have increased the size of the action bar, text, etc to help improve visibility and touch target size. Eve
I actually just uncovered it while working on something else. The height of the items in the overflow action menu is controlled by the android:listPreferredItemHeightSmall item in the application theme. So:
<style name="MyTheme" parent="@android:style/Theme.Holo">
<item name="android:listPreferredItemHeightSmall">72dp</item>
</style>
Gives us:
Changing android:listPreferredItemHeightSmall will possibly impact on some other things, but since in my case we are happy to have everything large, it works well.
