Class Overview

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 SeekBar.OnSeekBarChangeListener to be notified of the user's actions.

Summary
