Method Detail

onProgressChanged

void onProgressChanged(SeekBar seekBar,
                       int progress,
                       boolean fromTouch)

Notification that the progress level has changed. Clients can use the fromTouch parameter to distinguish user-initiated changes from those that occurred programmatically.

Parameters:

seekBar - The SeekBar whose progress has changed

progress - The current progress level. This will be in the range 0..max where max was set by ProgressBar.setMax(int). (The default value for max is 100.)

fromTouch - True if the progress change was initiated by a user's touch gesture.

onStartTrackingTouch

void onStartTrackingTouch(SeekBar seekBar)

Notification that the user has started a touch gesture. Clients may want to use this to disable advancing the seekbar.

Parameters:

seekBar - The SeekBar in which the touch gesture began

onStopTrackingTouch

void onStopTrackingTouch(SeekBar seekBar)

Notification that the user has finished a touch gesture. Clients may want to use this to re-enable advancing the seekbar.

Parameters:

seekBar - The SeekBar in which the touch gesture began
