Infinite ViewPager
android, android-viewpager, infinite-scroll
Solution
I was able to implement this using a little magic in my `MonthView`s, my `PagerAdapter`'s `OnPageChangeListener`, as well as with editing the source code of `ViewPager` itself. If anyone is interested in how I achieved it, check out the source code or comment with a specific question.
Problem
This seems possible, but I'm having a little trouble figuring out how to implement a `ViewPager` that can page indefinitely. My use case is for a calendar that shows a month at a time, but would be able to switch to any month by paging enough times. Currently I'm just `extending PagerAdapter`, and 3 custom `MonthViews` are added like so: ``` @Override public Object instantiateItem(View collection, int position) { final MonthView mv = new MonthView(HistoryMonthActivity.this); mv.setLayoutParams(new ViewSwitcher.LayoutParams( android.view.ViewGroup.LayoutParams.MATCH_PARENT, android.view.ViewGroup.LayoutParams.MATCH_PARENT)); mv.setSelectedTime(mTime); ((DirectionalViewPager) collection).addView(mv, 0); return mv; } ``` I would like to keep only 3 `MonthView`s in memory at a time, so that there isn't a huge delay in displaying data from my database on each `MonthView` when the user is tabbing. So every time a new page is shown, I will need to remove one `MonthView` and add one `MonthView`. If anyone has a better idea for the same functionality , I'd love to hear it! I'm thinking of trying to use a `FragmentStatePagerAdapter`.
