I think you're looking for the SeekBar. That's a View derived from the ProgressBar, but with a "thumb" so it looks like a slider control. A user can use the thumb to move left or right from min to max. You don't have to use it like a progress bar to track the progress of something, and can receive notifications that the user is touching and moving the thumb using a SeekBar.OnSeekBarChangeListener.
