onProgressChanged
abstract fun onProgressChanged(
seekBar: SeekBar!,
progress: Int,
fromUser: Boolean

Notification that the progress level has changed. Clients can use the fromUser parameter to distinguish user-initiated changes from those that occurred programmatically.
| Parameters |
seekBar |
SeekBar!: The SeekBar whose progress has changed |
progress |
Int: The current progress level. This will be in the range min..max where min and max were set by ProgressBar.setMin(int) and 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. |
onStartTrackingTouch
abstract fun onStartTrackingTouch(seekBar: SeekBar!): Unit
Notification that the user has started a touch gesture. Clients may want to use this to disable advancing the seekbar.
| Parameters |
seekBar |
SeekBar!: The SeekBar in which the touch gesture began |
onStopTrackingTouch
abstract fun onStopTrackingTouch(seekBar: SeekBar!): Unit
Notification that the user has finished a touch gesture. Clients may want to use this to re-enable advancing the seekbar.
| Parameters |
seekBar |
SeekBar!: The SeekBar in which the touch gesture began |
