android, seekbar drawable, what id/background, id/secondaryProgress and id/progress stand for?

I'm trying to make custom seekbar background. In examples I can find it is done via layer list with 3 layers. Layers' ids are:

@android:id/background
@android:id/secondaryProgress
@android:id/progress

What each item actually does?

Solution

  • secondaryProgress is an optional, additional progress in the bar. It is mostly used to display a buffering progress like you know it from streaming videos.

    progress and background should actually be self-explanatory. progress is the main progress, the loaded part, and background is the background of the SeekBar, the part that still needs to get loaded.
