public class NumberPicker
extends android.widget.LinearLayout
R.style.Theme the
widget presents the current value as an editable input field with an
increment button above and a decrement button below. Long pressing the
buttons allows for a quick change of the current value. Tapping on the input
field allows to type in a desired value.R.style.Theme_Holo
or R.style.Theme_Holo_Light the widget presents the current
value as an editable input field with a lesser value above and a greater
value below. Tapping on the lesser or greater value selects it by animating
the number axis up or down to make the chosen value current. Flinging up or
down allows for multiple increments or decrements of the current value. Long
pressing on the lesser and greater values also allows for a quick change of
the current value. Tapping on the current value allows to type in a desired
value.
For an example of using this widget, see TimePicker.
