Customization
| Method | Attribute | Description |
|---|---|---|
setBarColor(int color) | rfs_barColor | Color of scrollbar. Defaults to colorControlNormal attribute. Alpha of ~22% is applied to the drawable to match stock ListView fast scroller. |
setHandleNormalColor(int color) | rfs_handleNormalColor | Color of handle. Defaults to colorControlNormal attribute. |
setHandlePressedColor(int color) | rfs_handlePressedColor | Color of pressed handle. Defaults to colorAccent attribute. |
setTouchTargetWidth(int width) | rfs_touchTargetWidth | Width of the touch target. Defaults to 24dp (while the Android docs recommend at least 48dp, 24dp is more practical considering it will block touch in the right of the RecyclerView). |

setHidingEnabled(boolean enabled) | rfs_hidingEnabled | Whether scrollbar is hidden after delay. Defaults to true. |
