Summary
Public methods
public abstract void onProgressChanged (SeekBar seekBar,
int progress,

to distinguish user-initiated changes from those that occurred programmatically.
| Parameters |

ProgressBar.setMax(int), respectively. (The default values for
min is 0 and max is 100.) |
fromUser |
boolean: True if the progress change was initiated by the user. |
public abstract void onStartTrackingTouch (SeekBar seekBar)

to disable advancing the seekbar.
| Parameters |
|---|
seekBar |
SeekBar: The SeekBar in which the touch gesture began |
public abstract void onStopTrackingTouch (SeekBar seekBar)
Notification that the user has finished a touch gesture. Clients may want to use this
