Cant define smoothScrollBy

Question

I'm trying to use the Android Music app's TouchInterceptor class to allow a user to reorder a ListView.

It can be found here.

I've copied the file and created the necessary resources.

However, I'm left with 1 error. The method smoothScrollBy is undefined.

I'm using API 7 (2.1). Does it not exist in 2.1? If so, what should I be using? I'd really like to target the application to users at least running 2.1.

smoothScrollBy is in API level 8, which is Froyo (2.2).

You may have to settle for scrollBy, which has been around since API level 1.

Edit: for this specific problem, perhaps take a look at an earlier version of TouchInterceptor.java that was written for 2.1.

Is there an alternative I can use? – Andrew Mar 02 '11 at 20:27
Not in ListView. You can create your own list class though if scrollBy won't work for you. – Matthew Willis Mar 02 '11 at 20:31

You could consider doing a backport, at least see if it's doable (or might there be license issues?). The source is here. Knowing how to implement fling could be useful too.
