setSecondaryProgressTintList
Applies a tint to the secondary progress indicator, if one exists. Does not modify the current tint mode, which is SRC_ATOP by default.
The secondary progress indicator must be specified as a layer with id secondaryProgress in a LayerDrawable used as the progress drawable.
Subsequent calls to setProgressDrawable where the drawable contains a secondary progress indicator will automatically mutate the drawable and apply the specified tint and tint mode using setTintList.
