I think you need to use styles and themes. Check this out.

回答3:

You can either build custom (compound) views, look at Building Custom Components. Or you can use Fragments. Fragments are new in Honeycomb (Android 3.0), but there is a compatibility library that adds fragment support to lower android versions (can be found in your ANDROID_SDK/extras/android folder). Or you can mix both of course.
