You should take a look at the official guide on using Dialogs on Android: http://developer.android.com/guide/topics/ui/dialogs.html

And more specifically for collectors: http://developer.android.com/guide/topics/ui/controls/pickers.html

To select a number if your goal is → API 11: you can use the existing NumberPicker Android widget → http://developer.android.com/reference/android/widget/NumberPicker.html Use this widget in a special dialog box and do it.
