NO LONGER MAINTAINED
An android ViewPager extension allowing infinite scrolling.
You can use it with "standart"
PagerAdapter (inflating the pager with
but you can also use
FragmentPagerAdapter which allows you to fill the pager with
The ViewPager will actually create 2 additional Views/Fragments to fake the infinite loop.
To use it simply change
PagerAdapter is used only to create
Views (i.e. you don't use
then no more code changes are needed!
If you want to use
additional changes in the adapter must be done.
The adapter must be prepared to create 2 extra items e.g.:
- The original adapter creates 4 items:
- The modified adapter will have to create 6 items
- with mapping
[0->3, 1->0, 2->1, 3->2, 4->3, 5->0]
Sometimes "blinking" can be seen when paginating to first or last view (e.g. when you have a
NetworkImageView in your layout).
To remove this effect, simply call setBoundaryCaching( true ) on your
DEFAULT_BOUNDARY_CASHING to true, if you want to set boundary caching
LoopViewPager instances. This will prevent the first and last element from being destroyed,
and every time they need to be displayed the existing instances will be used.
