How to create the same google documentation custom dialog example of text message limit?

I'd want to create exactly the same custom dialog that you can find on Google documentation.

The dialog is this one:

Text Limit Dialog of Documentation

How I can do?

I need this dialog because I want that users can choose an integer to use it for something in my app.

Please help me.

I need exactly the same dialog.

Many Thanks

Its not a scroll list. It's a NumberPicker. You'll need API 11+ to implement this. http://developer.android.com/reference/android/widget/NumberPicker.html
