Minimal working example

In your adapter file implement IVolxAdapter and return your data as a list of objects:
public class UsersOwnAdapter extends RecyclerView.Adapter<UsersOwnAdapter.ViewHolder> implements IVolxAdapter {
private List<UserModel> mDataset;
public List<Object> getList() {
return new ArrayList<Object>(mDataset);
In your model file add @ValueArea annotation for the field that be rendered as a fast-scroll list
public class UserModel {

         new Volx.Builder()
Don't forget to sort your list before building Volx

More On Customization

If you want to customize colors, text sizes and layout sizes you can call it like:
	new Volx.Builder()
.setActiveColor(Color.CYAN) // the lightened color of right bar
.setBackgroundColor(Color.BLACK) // the color of right bar
.setTextColor(Color.WHITE) // the color of right bar letters
.setBarWidth(24) // the width of right bar in dp
.setBarHeightRatio(1f) // the height of right bar between 0 and 1 according to screen height
.setTextSize(Volx.FIT_NICELY) // the size of letters in right bar, FIT_NICELY handles it well , other values are also ok
.setMiddleTextSize(16) // the size of the letter in center circle
.setMiddleLayoutSize(48) // the size of the center circle in dp
.setMiddleBackgroundColor(Color.rgb(67, 67, 67)) // the color of the center circle
.setMiddleTextColor(Color.WHITE)  // the color of the letter in center circle
.setMiddleStrokeWidth(4) // the width of center circle stroke in dp
.setMiddleStrokeColor(Color.BLACK) // the color of right bar stroke
.setRightStrokeWidth(3) // the width of right bar stroke in dp
.setRightStrokeColor(Color.rgb(204, 204, 204)) // the color of middle circle stroke
.setMinItem(0) // the min amount of item required to show right bar
.setDelayMillis(3000) // the amount of time if there is no interaction on right bar, Volx.NEVER_CLOSE for never close
If you want to make volx invisible and remove it's listeners you can call method with your object:
Later you can activate volx again:
	if (volx.isInactive())
If your data updated , sort your data again and call the notifyValueDataChanged method:
