  - setRecyclerViewPosition
```
protected void setRecyclerViewPosition(float y)
```
  - getTargetPos
```
protected int getTargetPos(float currY)
```
    Computes the index where the RecyclerView should be scrolled to based on the currY (y-coordinate of the touch event in the scrollbar).
    
    Parameters:
    
    currY - y-coordinate of the touch event in the scrollbar
    
    Returns:
    
    index position in the RecyclerView
  - updateBubbleText
```
protected void updateBubbleText(int position)
```
    Update the text in the bubble based on the provided index.
    Override this method if you want to do something different when displaying the text in the bubble e.g. display a different text when the result of onCreateBubbleText is empty; OR apply different format depending on the result of onCreateBubbleText.
    The text can be set by calling:
```
 ...
 String bubbleTextString = bubbleTextCreator.onCreateBubbleText(index);
 bubble.setText(bubbleTextString);
 ...
 
```
    Parameters:
    
    position - position of the object that will be reflected in the bubble
  - getValueInRange
```
protected static int getValueInRange(int min,
                                     int max,
                                     int value)
```
  - setBubbleAndHandlePosition
```
protected void setBubbleAndHandlePosition(float y)
```
    Sets the y-position of the bubble and the handle based on the current y-position. Override this method if you want to adjust the min and max position of the handle and the bubble. E.g. the max position of the bubble is the same as the max position of the handle.
    
    Parameters:
    
    y - current active y height in the scrollbar
  - showBubble
```
protected void showBubble()
```
  - hideBubble
```
protected void hideBubble()
```
  - isHidden
```
public boolean isHidden()
```
  - isAutoHideEnabled
```
public boolean isAutoHideEnabled()
```
  - setAutoHideEnabled
```
public void setAutoHideEnabled(boolean autoHideEnabled)
```
    Allows to auto hide the FastScroller after x-milliseconds.
    Default value is true.
    
    Parameters:
    
    autoHideEnabled - true to enable auto Hide, false to disable

  - getAutoHideDelayInMillis
```
public long getAutoHideDelayInMillis()
```
  - setAutoHideDelayInMillis
```
public void setAutoHideDelayInMillis(long autoHideDelayInMillis)
```
    Sets the delay in milli-seconds to auto hide the scroller when untouched.
    Default value is 1000ms.
    
    Parameters:
    
    autoHideDelayInMillis - value in milli-seconds
  - setIgnoreTouchesOutsideHandle
```
public void setIgnoreTouchesOutsideHandle(boolean ignoreFlag)
```
    If enabled, it ignores touches outside handle.
    Default value is false.
    
    Parameters:
    
    ignoreFlag - true to ignore touches outside handle
    
    Since:

  - setHandleAlwaysVisible
```
public void setHandleAlwaysVisible(boolean enabled)
```
    If enabled, it will keep handle always visible with 50% transparency.
    Default value is false.
    
    Parameters:
    
    enabled - true to keep the handle always visible, false to hide always
    
    Since:
    
    5.0.5
  - setMinimumScrollThreshold
```
public void setMinimumScrollThreshold(int dy)
```
    If set, it ignores small scrolls, so scroller will be shown if enough amount of scroll is reached (it mimics fling gesture).
    - It works only if AutoHide is enabled.
    - Good values are between 60 and 100 pixel on real devices.
    Default value is 0 (scroller is always shown at each scroll amount).
    Parameters:
    
    dy - minimum scroll amount to show the scroller.
    
    Since:
    
    5.0.0-rc2
  - showScrollbar
```
public void showScrollbar()
```
    Shows the scrollbar with animation.
    
    Since:

    See Also:

  - hideScrollbar
```
public void hideScrollbar()
```
    Hides the scrollbar with animation.
    
    Since:
    
    5.0.0-rc2

  - toggleFastScroller
```
public void toggleFastScroller()
```
    Displays or Hides the FastScroller.
    The action is animated.

    setEnabled in class android.view.View
    
    Parameters:
    
    enabled - true to enable and show, false to hide with animation.
