ViewPager + FragmentPagerAdapter inside a DialogFragment gets “IllegalArgumentException:No view found…”

Try this:

In class AchGalleryDialog

MyFragmentAdapter adapter = new MyFragmentAdapter(getChildFragmentManager(),images);

instead of

MyFragmentAdapter adapter = new MyFragmentAdapter(getFragmentManager(),images); 

Because of this:

Hope this will help!
