Constructor Detail

SliderPager

public SliderPager(android.content.Context context)

SliderPager

public SliderPager(android.content.Context context,
                   android.util.AttributeSet attrs)

Method Detail

onDetachedFromWindow

protected void onDetachedFromWindow()

Overrides:

onDetachedFromWindow in class android.view.ViewGroup

setAdapter

public void setAdapter(PagerAdapter adapter)

Set a PagerAdapter that will supply views for this pager as needed.

Parameters:

adapter - Adapter to use

getAdapter

public PagerAdapter getAdapter()

Retrieve the current adapter supplying pages.

Returns:

The currently registered PagerAdapter

addOnAdapterChangeListener

public void addOnAdapterChangeListener(SliderPager.OnAdapterChangeListener listener)

Add a listener that will be invoked whenever the adapter for this SliderPager changes.

Parameters:

listener - listener to add

removeOnAdapterChangeListener

public void removeOnAdapterChangeListener(SliderPager.OnAdapterChangeListener listener)

Remove a listener that was previously added via addOnAdapterChangeListener(OnAdapterChangeListener).

Parameters:

listener - listener to remove

setCurrentItem

public void setCurrentItem(int item)

Set the currently selected page. If the SliderPager has already been through its first layout with its current adapter there will be a smooth animated transition between the current item and the specified item.

Parameters:

item - Item index to select

setCurrentItem

public void setCurrentItem(int item,
                           boolean smoothScroll)

Set the currently selected page.

Parameters:

item - Item index to select

smoothScroll - True to smoothly scroll to the new item, false to transition immediately

getCurrentItem

public int getCurrentItem()

setOnPageChangeListener

@Deprecated
public void setOnPageChangeListener(SliderPager.OnPageChangeListener listener)

Deprecated. Use addOnPageChangeListener(OnPageChangeListener) and removeOnPageChangeListener(OnPageChangeListener) instead.

Set a listener that will be invoked whenever the page changes or is incrementally scrolled. See ##OnPageChangeListener.

Parameters:

listener - Listener to set

addOnPageChangeListener

public void addOnPageChangeListener(SliderPager.OnPageChangeListener listener)

Add a listener that will be invoked whenever the page changes or is incrementally scrolled. See ##OnPageChangeListener.

Components that add a listener should take care to remove it when finished. Other components that take ownership of a view may call clearOnPageChangeListeners() to remove all attached listeners.

Parameters:

listener - listener to add

removeOnPageChangeListener

public void removeOnPageChangeListener(SliderPager.OnPageChangeListener listener)

Remove a listener that was previously added via addOnPageChangeListener(OnPageChangeListener).

Parameters:

listener - listener to remove

clearOnPageChangeListeners

public void clearOnPageChangeListeners()

Remove all listeners that are notified of any changes in scroll state or position.

setPageTransformer

public void setPageTransformer(boolean reverseDrawingOrder,
                               SliderPager.PageTransformer transformer)

Sets a ##PageTransformer that will be called for each attached page whenever the scroll position is changed. This allows the application to apply custom property transformations to each page, overriding the default sliding behavior.

Note: By default, calling this method will cause contained pages to use #View#LAYER_TYPE_HARDWARE. This layer type allows custom alpha transformations, but it will cause issues if any of your pages contain a ##android.view.SurfaceView and you have not called ##android.view.SurfaceView#setZOrderOnTop(boolean) to put that ##android.view.SurfaceView above your app content. To disable this behavior, call setPageTransformer(boolean, PageTransformer, int) and pass #View#LAYER_TYPE_NONE for pageLayerType.

Parameters:

reverseDrawingOrder - true if the supplied PageTransformer requires page views to be drawn from last to first instead of first to last.

transformer - PageTransformer that will modify each page's animation properties

setPageTransformer

public void setPageTransformer(boolean reverseDrawingOrder,
                               SliderPager.PageTransformer transformer,
                               int pageLayerType)

Sets a ##PageTransformer that will be called for each attached page whenever the scroll position is changed. This allows the application to apply custom property transformations to each page, overriding the default sliding behavior.

Parameters:

reverseDrawingOrder - true if the supplied PageTransformer requires page views to be drawn from last to first instead of first to last.

transformer - PageTransformer that will modify each page's animation properties

pageLayerType - View layer type that should be used for SliderPager pages. It should be either #View#LAYER_TYPE_HARDWARE, #View#LAYER_TYPE_SOFTWARE, or #View#LAYER_TYPE_NONE.

getChildDrawingOrder

protected int getChildDrawingOrder(int childCount,
                                   int i)

Overrides:

getChildDrawingOrder in class android.view.ViewGroup

getOffscreenPageLimit

public int getOffscreenPageLimit()

Returns the number of pages that will be retained to either side of the current page in the view hierarchy in an idle state. Defaults to 1.

Returns:

How many pages will be kept offscreen on either side

See Also:

setOffscreenPageLimit(int)

setOffscreenPageLimit

public void setOffscreenPageLimit(int limit)

Set the number of pages that should be retained to either side of the current page in the view hierarchy in an idle state. Pages beyond this limit will be recreated from the adapter when needed.

This is offered as an optimization. If you know in advance the number of pages you will need to support or have lazy-loading mechanisms in place on your pages, tweaking this setting can have benefits in perceived smoothness of paging animations and interaction. If you have a small number of pages (3-4) that you can keep active all at once, less time will be spent in layout for newly created view subtrees as the user pages back and forth.

You should keep this limit low, especially if your pages have complex layouts. This setting defaults to 1.

Parameters:

limit - How many pages will be kept offscreen in an idle state.

                              int offsetPixels)

This method will be invoked when the current page is scrolled, either as part of a programmatically initiated smooth scroll or a user initiated touch scroll. If you override this method you must call through to the superclass implementation (e.g. super.onPageScrolled(position, offset, offsetPixels)) before onPageScrolled returns.

Parameters:

position - Position index of the first page currently being displayed. Page position+1 will be visible if positionOffset is nonzero.

offset - Value from [0, 1) indicating the offset from the page at position.

offsetPixels - Value in pixels indicating the offset from position.

beginFakeDrag

public boolean beginFakeDrag()

Start a fake drag of the pager.

A fake drag can be useful if you want to synchronize the motion of the SliderPager with the touch scrolling of another view, while still letting the SliderPager control the snapping motion and fling behavior. (e.g. parallax-scrolling tabs.) Call fakeDragBy(float) to simulate the actual drag motion. Call endFakeDrag() to complete the fake drag and fling as necessary.

During a fake drag the SliderPager will ignore all touch events. If a real drag is already in progress, this method will return false.

Returns:

true if the fake drag began successfully, false if it could not be started.

See Also:

fakeDragBy(float), endFakeDrag()

endFakeDrag

public void endFakeDrag()

End a fake drag of the pager.

See Also:

beginFakeDrag(), fakeDragBy(float)

fakeDragBy

Fake drag by an offset in pixels. You must have called beginFakeDrag() first.

Parameters:

xOffset - Offset in pixels to drag by.

See Also:

beginFakeDrag(), endFakeDrag()

isFakeDragging

public boolean isFakeDragging()

Returns true if a fake drag is in progress.

Returns:

true if currently in a fake drag, false otherwise.

checkV - Whether the view v passed should itself be checked for scrollability (true), or just its children (false).

dx - Delta scrolled in pixels

x - X coordinate of the active touch point

y - Y coordinate of the active touch point

Returns:

true if child views of v can be scrolled by delta of dx.
