  - setFastScrollEnabled
```
public void setFastScrollEnabled(boolean enabled)
```
    Enables fast scrolling by letting the user quickly scroll through lists by dragging the fast scroll thumb. The adapter attached to the list may want to implement SectionIndexer if it wishes to display alphabet preview and jump between sections of the list.
    
    Parameters:

Fast scrollers shown in this way will not fade out and will be a permanent fixture within the list. Best combined with an inset scroll bar style that will ensure enough padding. This will enable fast scrolling if it is not already enabled.
    
    Parameters:
    alwaysShow - true if the fast scroller should always be displayed.
    See Also:
    View.setScrollBarStyle(int), setFastScrollEnabled(boolean)
  - isFastScrollAlwaysVisible
```
public boolean isFastScrollAlwaysVisible()

  - setVerticalScrollbarPosition
```
public void setVerticalScrollbarPosition(int position)
```
    Description copied from class: View
    
    Set the position of the vertical scroll bar. Should be one of View.SCROLLBAR_POSITION_DEFAULT, View.SCROLLBAR_POSITION_LEFT or View.SCROLLBAR_POSITION_RIGHT.
    
    Overrides:
    
    setVerticalScrollbarPosition in class View
    
    Parameters:
    position - Where the vertical scroll bar should be positioned.
  - isVerticalScrollBarHidden
```
protected boolean isVerticalScrollBarHidden()
```
    If fast scroll is visible, then don't draw the vertical scrollbar.
    
    Overrides:
    
    isVerticalScrollBarHidden in class View
    
    Returns:
    whether to temporarily hide the vertical scrollbar
  - setSmoothScrollbarEnabled
```
public void setSmoothScrollbarEnabled(boolean enabled)
```
    When smooth scrollbar is enabled, the position and size of the scrollbar thumb is computed based on the number of visible pixels in the visible items. This however assumes that all list items have the same height. If you use a list in which items have different heights, the scrollbar will change appearance as the user scrolls through the list. To avoid this issue, you need to disable this property. When smooth scrollbar is disabled, the position and size of the scrollbar thumb is based solely on the number of items in the adapter and the position of the visible items inside the adapter. This provides a stable scrollbar as the user navigates through a list of items with varying heights.
    
    Parameters:
    enabled - Whether or not to enable smooth scrollbar.
    See Also:
    setSmoothScrollbarEnabled(boolean)
  - isSmoothScrollbarEnabled
```
public boolean isSmoothScrollbarEnabled()
```
    Returns the current state of the fast scroll feature.
    
    Returns:
    True if smooth scrollbar is enabled is enabled, false otherwise.
    See Also:
    setSmoothScrollbarEnabled(boolean)
  - setOnScrollListener
```
public void setOnScrollListener(AbsListView.OnScrollListener l)
```
    Set the listener that will receive notifications every time the list scrolls.
    
    Parameters:
    l - the scroll listener
  - sendAccessibilityEvent
```
public void sendAccessibilityEvent(int eventType)
```
    Description copied from class: View
    
    Sends an accessibility event of the given type. If accessibility is not enabled this method has no effect. The default implementation calls View.onInitializeAccessibilityEvent(AccessibilityEvent) first to populate information about the event source (this View), then calls View.dispatchPopulateAccessibilityEvent(AccessibilityEvent) to populate the text content of the event source including its descendants, and last calls ViewParent.requestSendAccessibilityEvent(View, AccessibilityEvent) on its parent to resuest sending of the event to interested parties.
    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.sendAccessibilityEvent(View, int) is responsible for handling this call.
    
    Specified by:
    
    sendAccessibilityEvent in interface AccessibilityEventSource
    
    Overrides:
    
    sendAccessibilityEvent in class View
    
    Parameters:
    eventType - The type of the event to send, as defined by several types from AccessibilityEvent, such as AccessibilityEvent.TYPE_VIEW_CLICKED or AccessibilityEvent.TYPE_VIEW_HOVER_ENTER.
    See Also:
    View.onInitializeAccessibilityEvent(AccessibilityEvent), View.dispatchPopulateAccessibilityEvent(AccessibilityEvent), ViewParent.requestSendAccessibilityEvent(View, AccessibilityEvent), View.AccessibilityDelegate
  - onInitializeAccessibilityEvent
```
public void onInitializeAccessibilityEvent(AccessibilityEvent event)
```
    Description copied from class: View
    Initializes an AccessibilityEvent with information about this View which is the event source. In other words, the source of an accessibility event is the view whose state change triggered firing the event.
    Example: Setting the password property of an event in addition to properties set by the super implementation:
```
 public void onInitializeAccessibilityEvent(AccessibilityEvent event) {
     super.onInitializeAccessibilityEvent(event);
     event.setPassword(true);
 }
```
    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.
    
    Note: Always call the super implementation before adding information to the event, in case the default implementation has basic information to add.
    Overrides:
    
    onInitializeAccessibilityEvent in class AdapterView<ListAdapter>
    
    Parameters:
    event - The event to initialize.
    See Also:
    View.sendAccessibilityEvent(int), View.dispatchPopulateAccessibilityEvent(AccessibilityEvent)
  - onInitializeAccessibilityNodeInfo
```
public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info)
```
    Description copied from class: View
    Initializes an AccessibilityNodeInfo with information about this view. The base implementation sets:
    Subclasses should override this method, call the super implementation, and set additional attributes.
    
    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfo) is responsible for handling this call.
    Overrides:
    
    onInitializeAccessibilityNodeInfo in class AdapterView<ListAdapter>
    
    Parameters:
    info - The instance to initialize.
  - performAccessibilityAction
```
public boolean performAccessibilityAction(int action,
                                 Bundle arguments)
```
    Description copied from class: View
    
    Performs the specified accessibility action on the view. For possible accessibility actions look at AccessibilityNodeInfo.
    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.performAccessibilityAction(View, int, Bundle) is responsible for handling this call.
    
    Overrides:
    
    performAccessibilityAction in class View
    
    Parameters:
    action - The action to perform.
    arguments - Optional action arguments.
    
    Returns:
    Whether the action was performed.
  - isScrollingCacheEnabled
```
public boolean isScrollingCacheEnabled()
```
    Indicates whether the children's drawing cache is used during a scroll. By default, the drawing cache is enabled but this will consume more memory.
    
    Returns:
    true if the scrolling cache is enabled, false otherwise
    See Also:
    setScrollingCacheEnabled(boolean), View.setDrawingCacheEnabled(boolean)
  - setScrollingCacheEnabled
```
public void setScrollingCacheEnabled(boolean enabled)
```
    Enables or disables the children's drawing cache during a scroll. By default, the drawing cache is enabled but this will use more memory. When the scrolling cache is enabled, the caches are kept after the first scrolling. You can manually clear the cache by calling ViewGroup.setChildrenDrawingCacheEnabled(boolean).
    
    Parameters:
    enabled - true to enable the scroll cache, false otherwise
    See Also:
    isScrollingCacheEnabled(), View.setDrawingCacheEnabled(boolean)
  - setTextFilterEnabled
```
public void setTextFilterEnabled(boolean textFilterEnabled)
```

    Parameters:
    textFilterEnabled - true to enable type filtering, false otherwise
    See Also:
    Filterable
  - isTextFilterEnabled
```
public boolean isTextFilterEnabled()
```
    Indicates whether type filtering is enabled for this view
    
    Returns:
    true if type filtering is enabled, false otherwise

  - getFocusedRect
```
public void getFocusedRect(Rect r)
```
    Description copied from class: View
    
    When a view has focus and the user navigates away from it, the next view is searched for starting from the rectangle filled in by this method. By default, the rectangle is the View.getDrawingRect(android.graphics.Rect)) of the view. However, if your view maintains some idea of internal selection, such as a cursor, or a selected row or column, you should override this method and fill in a more specific rectangle.
    
    Overrides:
    
    getFocusedRect in class View
    
    Parameters:
    r - The rectangle to fill in, in this view's coordinates.
  - isStackFromBottom
```
public boolean isStackFromBottom()
```
    Indicates whether the content of this view is pinned to, or stacked from, the bottom edge.
    
    Returns:
    true if the content is stacked from the bottom edge, false otherwise
  - setStackFromBottom
```
public void setStackFromBottom(boolean stackFromBottom)
```
    When stack from bottom is set to true, the list fills its content starting from the bottom of the view.
    
    Parameters:
    stackFromBottom - true to pin the view's content to the bottom edge, false to pin the view's content to the top edge
  - onSaveInstanceState
```
public Parcelable onSaveInstanceState()
```
    Description copied from class: View
    
    Hook allowing a view to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can not be reconstructed later. For example, you will never store your current position on screen because that will be computed again when a new instance of the view is placed in its view hierarchy.
    Some examples of things you may store here: the current cursor position in a text view (but usually not the text itself since that is stored in a content provider or other persistent storage), the currently selected item in a list view.
    
    Overrides:
    
    onSaveInstanceState in class View
    
    Returns:
    Returns a Parcelable object containing the view's current dynamic state, or null if there is nothing interesting to save. The default implementation returns null.
    See Also:
    View.onRestoreInstanceState(android.os.Parcelable), View.saveHierarchyState(android.util.SparseArray), View.dispatchSaveInstanceState(android.util.SparseArray), View.setSaveEnabled(boolean)
  - onRestoreInstanceState
```
public void onRestoreInstanceState(Parcelable state)
```
    Description copied from class: View
    
    Hook allowing a view to re-apply a representation of its internal state that had previously been generated by View.onSaveInstanceState(). This function will never be called with a null state.
    
    Overrides:
    
    onRestoreInstanceState in class View
    
    Parameters:
    state - The frozen state that had previously been returned by View.onSaveInstanceState().

                  Rect previouslyFocusedRect)
```
    Description copied from class: View
    
    Called by the view system when the focus state of this view changes. When the focus change event is caused by directional navigation, direction and previouslyFocusedRect provide insight into where the focus is coming from. When overriding, be sure to call up through to the super class so that the standard focus handling will occur.
    
    Overrides:
    
    onFocusChanged in class View
    
    Parameters:
    gainFocus - True if the View has focus; false otherwise.
    direction - The direction focus has moved when requestFocus() is called to give this view focus. Values are View.FOCUS_UP, View.FOCUS_DOWN, View.FOCUS_LEFT, View.FOCUS_RIGHT, View.FOCUS_FORWARD, or View.FOCUS_BACKWARD. It may not always apply, in which case use the default.
    previouslyFocusedRect - The rectangle, in this view's coordinate system, of the previously focused view. If applicable, this will be passed in as finer grained information about where the focus is coming from (in addition to direction). Will be null otherwise.
  - requestLayout
```
public void requestLayout()
```
    Description copied from class: View
    
    Call this when something has changed which has invalidated the layout of this view. This will schedule a layout pass of the view tree.

  - getTopFadingEdgeStrength
```
protected float getTopFadingEdgeStrength()
```
    Description copied from class: View
    
    Returns the strength, or intensity, of the top faded edge. The strength is a value between 0.0 (no fade) and 1.0 (full fade). The default implementation returns 0.0 or 1.0 but no value in between. Subclasses should override this method to provide a smoother fade transition when scrolling occurs.
    
    Overrides:

  - onMeasure
```
protected void onMeasure(int widthMeasureSpec,
             int heightMeasureSpec)
```
    Description copied from class: View
    
    Measure the view and its content to determine the measured width and the measured height. This method is invoked by View.measure(int, int) and should be overriden by subclasses to provide accurate and efficient measurement of their contents.
    
    CONTRACT: When overriding this method, you must call View.setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by View.measure(int, int). Calling the superclass' View.onMeasure(int, int) is a valid use.
    
    The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override View.onMeasure(int, int) to provide better measurements of their content.
    
    If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (View.getSuggestedMinimumHeight() and View.getSuggestedMinimumWidth()).
    
    Overrides:
    
    onMeasure in class View
    
    Parameters:
    widthMeasureSpec - horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
    heightMeasureSpec - vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
    See Also:
    View.getMeasuredWidth(), View.getMeasuredHeight(), View.setMeasuredDimension(int, int), View.getSuggestedMinimumHeight(), View.getSuggestedMinimumWidth(), View.MeasureSpec.getMode(int), View.MeasureSpec.getSize(int)

  - onAttachedToWindow
```
protected void onAttachedToWindow()
```
    Description copied from class: View
    
    This is called when the view is attached to a window. At this point it has a Surface and will start drawing. Note that this function is guaranteed to be called before View.onDraw(android.graphics.Canvas), however it may be called any time before the first onDraw -- including before or after View.onMeasure(int, int).
    
    Overrides:
    
    onAttachedToWindow in class View
    
    See Also:
    View.onDetachedFromWindow()
  - onDetachedFromWindow

  - onWindowFocusChanged
```
public void onWindowFocusChanged(boolean hasWindowFocus)
```
    Description copied from class: View
    
    Called when the window containing this view gains or loses focus. Note that this is separate from view focus: to receive key events, both your view and its window must have focus. If a window is displayed on top of yours that takes input focus, then your own window will lose focus but the view focus will remain unchanged.
    
    Overrides:
    
    onWindowFocusChanged in class View
    
    Parameters:
    hasWindowFocus - True if the window containing this view now has focus, false otherwise.

```
    Description copied from class: ViewGroup
    
    Bring up a context menu for the specified view or its ancestors.
    In most cases, a subclass does not need to override this. However, if the subclass is added directly to the window manager (for example, ViewManager.addView(View, android.view.ViewGroup.LayoutParams)) then it should override this and show the context menu.
    
    Specified by:
    
    showContextMenuForChild in interface ViewParent
    
    Overrides:
    
    showContextMenuForChild in class ViewGroup

  - onGenericMotionEvent
```
public boolean onGenericMotionEvent(MotionEvent event)
```
    Description copied from class: View
    Implement this method to handle generic motion events.
    Generic motion events describe joystick movements, mouse hovers, track pad touches, scroll wheel movements and other input events. The source of the motion event specifies the class of input that was received. Implementations of this method must examine the bits in the source before processing the event. The following code example shows how this is done.
    Generic motion events with source class InputDevice.SOURCE_CLASS_POINTER are delivered to the view under the pointer. All other generic motion events are delivered to the focused view.
```
 public boolean onGenericMotionEvent(MotionEvent event) {
     if ((event.getSource() & InputDevice.SOURCE_CLASS_JOYSTICK) != 0) {
         if (event.getAction() == MotionEvent.ACTION_MOVE) {
             // process the joystick movement...
             return true;
         }
     }
     if ((event.getSource() & InputDevice.SOURCE_CLASS_POINTER) != 0) {
         switch (event.getAction()) {
             case MotionEvent.ACTION_HOVER_MOVE:
                 // process the mouse hover movement...
                 return true;
             case MotionEvent.ACTION_SCROLL:
                 // process the scroll wheel movement...
                 return true;
         }
     }
     return super.onGenericMotionEvent(event);
 }
```
    Overrides:
    
    onGenericMotionEvent in class View
    
    Parameters:
    event - The generic motion event being processed.
    
    Returns:
    True if the event was handled, false otherwise.
  - draw
```
public void draw(Canvas canvas)
```
    Description copied from class: View
    
    Manually render this view (and all of its children) to the given Canvas. The view must have already done a full layout before this function is called. When implementing a view, implement View.onDraw(android.graphics.Canvas) instead of overriding this method. If you do need to override this method, call the superclass version.
    
    Overrides:
    
    draw in class View
    
    Parameters:
    canvas - The Canvas to which the View is rendered.
  - setOverScrollEffectPadding

                              int rightPadding)
```
  - requestDisallowInterceptTouchEvent
```
public void requestDisallowInterceptTouchEvent(boolean disallowIntercept)
```
    Description copied from class: ViewGroup
    
    Called when a child does not want this parent and its ancestors to intercept touch events with ViewGroup.onInterceptTouchEvent(MotionEvent).
    This parent should pass this call onto its parents. This parent must obey this request for the duration of the touch (that is, only clear the flag after this parent has received an up or a cancel.
    
    Specified by:
    
    requestDisallowInterceptTouchEvent in interface ViewParent
    
    Overrides:
    
    requestDisallowInterceptTouchEvent in class ViewGroup
    
    Parameters:
    disallowIntercept - True if the child does not want the parent to intercept touch events.
  - onInterceptTouchEvent
```
public boolean onInterceptTouchEvent(MotionEvent ev)
```
    Description copied from class: ViewGroup
    Implement this method to intercept all touch screen motion events. This allows you to watch events as they are dispatched to your children, and take ownership of the current gesture at any point.
    Using this function takes some care, as it has a fairly complicated interaction with View.onTouchEvent(MotionEvent), and using it requires implementing that method as well as this one in the correct way. Events will be received in the following order:
    1. You will receive the down event here.
    2. The down event will be handled either by a child of this view group, or given to your own onTouchEvent() method to handle; this means you should implement onTouchEvent() to return true, so you will continue to see the rest of the gesture (instead of looking for a parent view to handle it). Also, by returning true from onTouchEvent(), you will not receive any following events in onInterceptTouchEvent() and all touch processing must happen in onTouchEvent() like normal.
    3. For as long as you return false from this function, each following event (up to and including the final up) will be delivered first here and then to the target's onTouchEvent().
    4. If you return true from here, you will not receive any following events: the target view will receive the same event but with the action MotionEvent.ACTION_CANCEL, and all further events will be delivered to your onTouchEvent() method and no longer appear here.
    Overrides:
    
    onInterceptTouchEvent in class ViewGroup
    
    Parameters:
    ev - The motion event being dispatched down the hierarchy.
    
    Returns:
    Return true to steal motion events from the children and have them dispatched to this ViewGroup through onTouchEvent(). The current target will receive an ACTION_CANCEL event, and no further messages will be delivered here.
  - addTouchables
```
public void addTouchables(ArrayList<View> views)
```
    Add any touchable views that are descendants of this view (possibly including this view if it is touchable itself) to views.

    Parameters:
    position - Scroll to this adapter position.
  - smoothScrollToPositionFromTop
```
public void smoothScrollToPositionFromTop(int position,

                                 int duration)
```
    Smoothly scroll to the specified adapter position. The view will scroll such that the indicated position is displayed offset pixels from the top edge of the view. If this is impossible, (e.g. the offset would scroll the first or last item beyond the boundaries of the list) it will get as close as possible. The scroll will take duration milliseconds to complete.
    
    Parameters:
    position - Position to scroll to
    offset - Desired distance in pixels of position from the top of the view when scrolling is finished
    duration - Number of milliseconds to use for the scroll

    Smoothly scroll to the specified adapter position. The view will scroll such that the indicated position is displayed offset pixels from the top edge of the view. If this is impossible, (e.g. the offset would scroll the first or last item beyond the boundaries of the list) it will get as close as possible.
    
    Parameters:
    position - Position to scroll to
    offset - Desired distance in pixels of position from the top of the view when scrolling is finished
  - smoothScrollToPosition
```
public void smoothScrollToPosition(int position,
                          int boundPosition)
```
    Smoothly scroll to the specified adapter position. The view will scroll such that the indicated position is displayed, but it will stop early if scrolling further would scroll boundPosition out of view.
    
    Parameters:
    position - Scroll to this adapter position.
    boundPosition - Do not scroll if it would move this adapter position out of view.
  - smoothScrollBy
```
public void smoothScrollBy(int distance,
                  int duration)
```
    Smoothly scroll by distance pixels over duration milliseconds.
