SeekBar in Android
A SeekBar is a type of ProgressBar that allows users to change the progress value by dragging the bar left or right. It’s commonly used for tasks such as adjusting volume or scrubbing through media like songs and videos. SeekBar works with the setOnSeekBarChangeListener interface, which provides three key methods:
1. onProgressChanged: Triggered when the progress changes, allowing developers to apply logic based on the new value.
2. onStartTrackingTouch: Called automatically when the user begins dragging the SeekBar.
3. onStopTrackingTouch: Called automatically when the user stops dragging.
When an accessibility service is active, the SeekBar can typically be controlled via swipe gestures (up or down) or the volume keys. To ensure accessibility, developers should use the standard Android SeekBar instead of creating custom versions and make sure to add an accessible label to it.
