DroidUX Gallery Pack consists of the DroidUX GalleryFlow™ components collection. The GalleryFlow components are
extension of the Gallery widgets with fixes, enhanced features, and other improvements to boost
the performance and polish the behavior of the widgets. Using the
GalleryFlow widgets, you can
achieve a lot more interesting effects which are not readily available or a lot more difficult to achieve with the stock Gallery widget.
Some of the enhancements implemented in these widgets includes:
GalleryFlowwidgets add a reflection effect to the views returned by the adapter's getView(int, View, ViewGroup) method. If you want to turn off the reflection effect, just set the
false. You can customize the reflection by changing certain attributes, e.g.
dux_floorGapto adjust the distance to the 'floor',
dux_reflectionHeightto set the height of the reflection, etc.
GalleryFlowwidget has its own particular flow behavior which you can customize to achieve certain effects, such as cover/album flow effect (using com.droidux.widget.gallery.GalleryFlowCover), zoom flow (com.droidux.widget.gallery.GalleryFlowZoom), scale flow (com.droidux.widget.gallery.GalleryFlowScale), carousel flow (com.droidux.widget.gallery.GalleryFlowCarousel), wall effect (com.droidux.widget.gallery.GalleryFlowWall), etc.
GalleryFlowwidgets has a working implementation of the view recycling/caching mechanism, which means improved performance. As discussed here and here, the Android stock Gallery widget doesn't have a working view recycling/caching mechanism . It's either broken or not (yet) fully implemented (see Issue #3376). This will slow down the performance of the application using the Gallery widget, because that means the Adapter will have to create new View for every item in the data set, instead of reusing an unused view (like the ListView).
com.droidux.widget.adapters.UrlImageAdapter. (New in version 1.5) When the adapter implements the com.droidux.widget.adapters.UrlImageAdapter, the web images will be downloaded using an internal downloader which has been optimized to efficiently manage the tasks/threads to download the images.
GalleryFlow widgets wrap their adapter views with a com.droidux.interfaces.WrapperViewInterface to add certain effects such as reflection, etc.
Therefore, functions that return adapter views, such as getChildAt(int), getSelectedView(), etc,
will return the com.droidux.interfaces.WrapperViewInterface instead of the original adapter views. To get the original view, you need to call the
GalleryFlow widgets use a proprietary optimization mechanism which is not compatible with hardware acceleration (introduced in Honeycomb, API-11).
Therefore, if you're using the
GalleryFlow widgets, please make sure that the hardware acceleration is disabled at least on the
by setting the
hardwareAccelerated attribute to
