There are lots of way to style ListViews to give them elegant look, but all of them involve modyfying the adapter or writing additional code.
With the release of Android 4.0, unfortunetely things have to change. Google polished their Holo theme and gave it new look. All of the developers are now encouraged to use it, in order to make all apps look the same.
And here's the problem. Google rolled out 4.0, but there are still people using older Android versions. We can't just leave our previous custom application themes and use Holo, because it will ruin visual experience for users with older devices. And we can't force 4.0 users just to use Holo, because let's be honest - it's still not perfect.
The goal is to use builtin themes system and prepare some alternatives for Holo, which will look great on all devices. Then we can just switch between Holo and our themes with just setTheme() and no additional problems. Unfortunetely it's not that simple. We are limited to the capabilities of existing theme system and some things are just hard to do. And here comes my question.
Taking everything I've mentioned into consideration, how can we control ListView look? I'm not able to figure out, how to:
- create list with rounded corners and make sure the selector background doesn't ruin it when selecting first/last element
- create rounded corners not for the list but sections separated by headers, something like here:
The solution should affect ListViews created by PreferenceActivity without any additional lines of code. Everything should be contained in the theme:
<theme name="SampleTheme" parent="android:Theme">
...
</theme>
I kindly ask not to post solutions that do not use styles & themes. They can be easily found in another questions, here on Stack Overflow.
