java.lang.Object
	android.view.View				Drawable.Callback KeyEvent.Callback
		android.view.ViewGroup			ViewManager ViewParent
			android.widget.FrameLayout
				android.widget.TimePicker

A view for selecting the time of day, in either 24 hour or AM/PM mode. The hour, each minute digit, and AM/PM (if applicable) can be conrolled by vertical spinners. The hour can be entered by keyboard input. Entering in two digit hours can be accomplished by hitting two digits within a timeout of about a second (e.g. '1' then '2' to select 12). The minutes can be entered by entering single digits. Under AM/PM mode, the user can hit 'a', 'A", 'p' or 'P' to pick.

Also see ViewGroup.LayoutParams for layout attributes.

For a dialog using this view, see TimePickerDialog.

Nested Classes

TimePicker.OnTimeChangedListener	The callback interface used to indicate the time has been adjusted.
TimePicker.OnTimeSetListener	The callback interface used to indicate the user is done filling in the time (they clicked on the 'Set' button).
