You should take a look to the official guide for Dialogs usage in Android: http://developer.android.com/guide/topics/ui/dialogs.html

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

For a number picker if your target is > to API 11: you can use the existing Android widget NumberPicker -> http://developer.android.com/reference/android/widget/NumberPicker.html Use this widget in a custom dialog box and it's done.
