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?
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.
