Android的＆QUOT; iPod的滚轮＆QUOT;搜索栏

我试图创建一个搜索栏是每一位同在Android上的标准搜索栏，但有一个重要区别：我希望它是圆形的操作方式类似于iPod的点击式转盘。我到处找网上，但似乎无法找到正确的解决方案。有没有人有一个想法？我见过有暂存盘DJ应用程序，所以我知道这样的事情都是可能的。你的帮助是非常AP preciated。

I'm trying to create a seekbar that is every bit the same as the standard seekbar in Android, but with one major difference: I want it to be circular and operate similarly to the iPod clickwheel. I've looked everywhere online, but can't seem to find the correct solution. Does anyone have an idea? I've seen DJ apps that have scratch disks, so I know such things are possible. Your help is much appreciated.

谢谢！
