SeekBarpublic class SeekBar extends AbsSeekBar | A SeekBar is an extension of ProgressBar that adds a draggable thumb. The user can touch
the thumb and drag left or right to set the current progress level or use the arrow keys.
Placing focusable widgets to the left or right of a SeekBar is discouraged.
Clients of the SeekBar can attach a {@link SeekBar.OnSeekBarChangeListener} to
be notified of the user's actions. |
