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
.
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.
