ViewPager + Adapter in Fragment => laggy swiping

Question

I have a ViewPager with some fragments. Each fragment has a ListView in a SlidingDrawer (=invisible before swiping) with an Arra

Answer 1

My Question is, wether it is possible to set the Adapter after swiping when it Pager is idle?

There is the OnPageChangeListener that you could set on the ViewPager to monitor the swipe gestures. You could then use the onPageSelected()(or the onPageScrollStateChanged() to monitor the current state) method to get notified when a new page has been selected and start from that method the loading of data.

Also, make sure the ListView are responsible for the lag and not some other part of your code.
