Is there any tested and usable component we can use to show "Count selector" like this?
Our target is to get it working from API v7 .
(Taken from DatePickerDialog)
After some deep testing and using, this is a list of usable Picker widget libraries
- Android Wheel http://code.google.com/p/android-wheel/
- Number Picker from Michael Novak https://github.com/mrn/numberpicker
- Date Slider (which can be easily adjusted) http://code.google.com/p/android-dateslider/
- Horizontal slider widget http://blog.sephiroth.it/2012/01/28/android-wheel-widget/
- Backport of Android 4.2 NumberPicker https://github.com/SimonVT/android-numberpicker
When kindly omitted the solution in accepted answer, these widget libraries are very usable if you need alter the design, and you like the way iOS does the wheel slider picker.
I think this one is better:
https://github.com/SimonVT/android-numberpicker
it has the same look of android 4.2 number picker:
another alternative is using the HoloEverywhere library, which has plenty of native look&feel of android jelly bean
