How to show a long list without using a ListView

I am working on an exercise program, and one part is to pick an exercise, then how often you do it, with how much weight.

So, I want all this information on one screen, so going to a ListView would be annoying, I believe.

But, there may be over 100 exercises, so my current approach of using a Spinner has a problem.

It would seem that if my list is 开发者_JAVA技巧sorted, then if you can hit a key and jump to that letter then it would speed up searching for the user.

So, would it make sense to have a custom component that is basically just a dropdown list (http://msdn.microsoft.com/en-us/library/aa511458.aspx) or is there a better way to allow users to navigate a long list without going to a new screen?

You can try autocomplete widget that is described here
