问题
In res/values-v11/styles.xml, I can't use Theme.Holo.Light.NoActionBar because it was added in API level 13. Can I use Theme.Light.NoTitleBar instead, with no visual differences? As far as I can tell, they should both have a white background, status and navigation bars, and nothing else.
回答1:
Theme.Light.NoTitleBar is slightly different. The easiest way to resolve this and stay compatible back to Honeycomb is to create your own style that extends Theme.Holo.Light, but removes the Action Bar. Just create a style with the following definition:
false
true
回答2:
As far as I know, the Theme.Light.NoTitleBar is based on older API level. You will get the style of Android 2.3. But Theme.Holo.Light.NoActionBar can give you the style of 4.0 or upper.
