  <p>All this code above it's working perfectly.</p>
  
  <p>Now I'm trying to create a PopupWindow (or DialogFragment) who will have my ViewPager.</p>
  
  <p>I modified my code for this (now my XML activity_principal1 have just a Button and the new XML popup have my ViewPager)</p>
  
  <pre><code>public class Activity_principal1 extends FragmentActivity {
  
  private LayoutInflater inflater;
  private View view;

      setContentView(R.layout.activity_principal1);
  
      List&lt;Fragment&gt; fragments = getFragments();
      AcoesMuscularesAdapter ama = new AcoesMuscularesAdapter(getSupportFragmentManager(), fragments);
  
      inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      view = inflater.inflate(R.layout.popup, null,true);
  
      ViewPager vp_contentAcoesMusculares_SequenciaExercicios = (ViewPager) view.findViewById(R.id.vp_contentAcoesMusculares_SequenciaExercicios);
      vp_contentAcoesMusculares_SequenciaExercicios.setAdapter(ama);
  
      window = new PopupWindow(view);
  
      abrir = (Button) findViewById(R.id.abrir);
      abrir.setOnClickListener(new OnClickListener() {
  
          @Override
          public void onClick(View v) {
              window.showAsDropDown(v);
          }
      });
  }
  
  private List&lt;Fragment&gt; getFragments(){
      List&lt;Fragment&gt; fList = new ArrayList&lt;Fragment&gt;();
