Question

I have an activity holding a fragment, in this fragment there is a button , when it is clicked, a dialog is popped out.

In this dialog, there is a Viewpager, which

Answer 1

The error sounds like it's looking for the id pager in the xml file for DummyFragment (fragment_dummy_layout.xml). I wonder if this is due to calling View v = inflater.inflate(R.layout.fragment_dummy_layout, container, false); in the same file as setContentView(R.layout.dialog);. Have you tried separating DummyFragment into it's own file?

You could also try

View v = getActivity().getLayoutInflater().inflate(R.layout.fragment_dummy_layout, 
        container, false);
