We have an app using a slightly modified Holo theme (dark). On one screen you could have a number of Ti.UI.Picker controls, all with similar (or even identical) drop-down rows (simple one-column text). When you tap e.g. the topmost picker control and the drop-down list is displayed, the drop-down items can be pretty hard to distinguish from the other picker controls below (which the drop-down list temporarily hides) due to the very dark grey background color used by default (the background of the pickers is black). I would like to make the picker items stand out more, e.g. by using a lighter background color for them, but I cannot find a way using the properties of Ti.UI.Picker and Ti.UI.PickerRow. We do however have a custom styles.xml file in the project (under /platform/android/res/values), so if you could change the layout there somehow that would be fine as well. I have not done any such style modifications myself previously and I do not know what the Ti.UI.Picker control translates to in the Android theme, so any help would be much appreciated (preferably with a xml and/or Titanium JavaScript code example).
Application type: mobile, Titanium SDK: 3.1.1 GA, Platform & version: Android 4.x, Device: various Android devices, e.g. Samsung Galaxy SII
