How to use NumberPicker in Android app with API 7?

Question

The minimum sdk of my app is 7, but I can use DialogFragment which is from sdk version 11, because it is in the support library which is in my lib directory.

I'd like to make something like this example: http://developer.android.com/guide/topics/ui/controls/pickers.html

But I want to use the NumberPicker widget, which is from sdk version 11 too, but my app does not allow this. Do I have to add other support library?

How can I use this component?

Thank you.

Do I have to add other support library?

The Android Support library does not offer NumberPicker. Other people have created their own backports of NumberPicker that you could use, such as SimonVT's one.
