I've implemented a simple search dialog that performs a custom search of the data within my app (Via a custom provider) as according to the guidelines here: http://developer.android.com/guide/topics/search/search-dialog.html
The problem is that the search bar's colors and size (exceeds the height of the action bar, etc) do not work within the design of my app. I know how to create a theme in my styles.xml file, but I do not know how to target the Android search dialog and suggestions listView. Does anyone know how I can do this?
After 13 hours spent on the question, it turns out it's not possible for some reason. Apps that do have visually customized search dialogs- even if it's just the colours - must implement them manually, and probably don't use the standard search interfaces.
as per google docs SearchDialog is
"The search dialog is a UI component that's controlled by the Android system."
So to have a control over search visuals use as for today :
ActionBarSherlock dev branch
https://github.com/JakeWharton/ActionBarSherlock/tree/dev
and this :
http://developer.android.com/guide/topics/search/search-dialog.html#ConfiguringWidget
to implement fully controlable search
