To give an application a more android-like feeling I'd like to switch the style of choosing between two "ways" to something like the lockscreen-ring, where you can drag the center to the right/left. I've googled a lot, only thing I've "found" was that the Android code must be somewhere hidden in the framework APK file, so I thought maybe you guys know where I could find something like that, or an 3rd party "view" under free license?
Thank you.
You can use the open source GlowPadView for Android 3.0 and above. There is no implementation available for Gingerbread and below AFAIK, and you will have to make one yourself.
