I'm developing an app with a ViewPager for lateral scrolling tables, sometimes i need to change the adapter to load a different set of tables. I've tried to do the following:

mViewPager.setAdapter(new pagerAdapterPushed(getSupportFragmentManager()));
mViewPager.getAdapter().notifyDataSetChanged();
indicator.setViewPager(mViewPager);
indicator.invalidate();
mViewPager.invalidate();

but it always reload the previous data. Isn't it possibile to change the adapter of a ViewPager?

android adapter android-viewpager

You need to override public int getItemPosition (Object object) in pager adapter. For every element in the viewpager, you need to return POSITION_UNCHANGED (if it is still in the pager) or POSITION_NONE (if it was removed). Otherwise the view pager won't know something has changed. I wouldn't recommend setting a new adapter, just clearing out the data in the old one.
