How can I create a list where I can rearrange list items with dragging list rows to another row and so on (to change to order)?
Just like on the HTC Hero in the clocks app where you can rearrange the order of clocks?

The Android drag and drop framework enables you to add interactive drag and drop capabilities to your app. With drag and drop, users can copy or move text, images, objects—any content that can be represented by a URI—from one View to another within an app or, in multi-window mode, between apps.
A double tap and hold allows you to grab and then drag. A two-finger tap acts as a right click. A two-finger drag reproduces the mouse wheel scrolling action.
FrameLayout is a ViewGroup where if you add a child view to it, the child view will be positioned to the top left corner of the screen. So you can wrap all the UI components in a ViewGroup e.g LinearLayout or ScrollLayout and add it under the FrameLayout. Then add button/view which you want to drag.
Even though this question is already answered. I struggled using the music app as an example, so I created a simple Drag and Drop List project to help others that can be found here

You can also try my recent implementation here:
It gives smooth scrolling while dragging and supports list items with arbitrary heights. Lots of jumpy behavior has also been removed as compared to the TouchInterceptor.

It's in platform/packages/apps/Music/src/com/android/music/TouchInterceptor.java. Here's a direct link:

Hint: download the android sources and have a look how the Music app (packages\apps\Music) implements this functionality.
