android - ViewPager with Fragments inside PopupWindow (or DialogFragment) - Error no view found for id for fragment

Question

I created a FragmentActivity with this code below

public class Activity_principal1 extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_principal1);

        List<Fragment> fragments = getFragments();
        AcoesMuscularesAdapter ama = new AcoesMuscularesAdapter(getSupportFragmentManager(), fragments);
        ViewPager vp_contentAcoesMusculares_SequenciaExercicios = (ViewPager) findViewById(R.id.vp_contentAcoesMusculares_SequenciaExercicios);
        vp_contentAcoesMusculares_SequenciaExercicios.setAdapter(ama);

    }

    private List<Fragment> getFragments(){
        List<Fragment> fList = new ArrayList<Fragment>();
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 1",1));
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 2",2));
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 3",3));
        return fList;
    }

}

and this is my XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/framelayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white" >

<android.support.v4.view.ViewPager
    android:id="@+id/vp_contentAcoesMusculares_SequenciaExercicios"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    android:layout_marginTop="5dp"
    android:background="#fff" />

</RelativeLayout>

The FragmentAcoesMusculares (the code inside the method getFragments()) is this class below

public class FragmentAcoesMusculares extends Fragment{

    public static final String EXTRA_MESSAGE = "EXTRA_MESSAGE";

    public static final FragmentAcoesMusculares newInstance(String message,int item)
    {
        FragmentAcoesMusculares f = new FragmentAcoesMusculares();
        Bundle bdl = new Bundle(item);
        f.item = item;
        bdl.putString(EXTRA_MESSAGE, message);
        f.setArguments(bdl);
        return f;
    }


    private int item;
    private ImageView images;
    private String urlString = "";
    int i = 0;;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
         final View v = inflater.inflate(R.layout.linha_acoesmusculares_viewpager, container, false);

         images = (ImageView) v.findViewById(R.id.images);
         final Runnable r = new Runnable() {

            @Override
            public void run() {
            if(i == 0){
                urlString = "http://54.232.207.226/atlas.limittraining.com.br/thumb/grupo-muscular-sequencia/1/0/0/bb91e662b4fd6ffde74757ff9bd6e108.jpg";
            }else{
                urlString = "http://54.232.207.226/atlas.limittraining.com.br/thumb/grupo-muscular-sequencia/1/0/0/7730258ca72a75365d0c4b92a1a68a0a.jpg";
            }

            AQuery aquery = new AQuery(images);
            aquery.image(urlString);
            i++;
            if(i >= 2){
                i = 0;
            }
            images.postDelayed(this, 1500);
        }
    };
    images.postDelayed(r, 1500);

    return v;
}

}

and this is my Adapter

public class AcoesMuscularesAdapter extends FragmentPagerAdapter{

    private List<Fragment> fragments;

    public AcoesMuscularesAdapter(FragmentManager fm, List<Fragment> fragments){
        super(fm);
        this.fragments = fragments;
    }

    @Override
    public Fragment getItem(int position) {
        return this.fragments.get(position);
    }

    @Override
    public int getCount() {
        return this.fragments.size();
    }
}

All this code above it's working perfectly.

Now I'm trying to create a PopupWindow (or DialogFragment) who will have my ViewPager.

I modified my code for this (now my XML activity_principal1 have just a Button and the new XML popup have my ViewPager)

public class Activity_principal1 extends FragmentActivity {

private LayoutInflater inflater;
private View view;
private PopupWindow window;
private Button abrir;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_principal1);

    List<Fragment> 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<Fragment> getFragments(){
    List<Fragment> fList = new ArrayList<Fragment>();
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 1",1));
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 2",2));
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 3",3));
    return fList;
}

}

and FINALLY, this is the error that is occurring now.

Answer 1

I found a way to my problem.

Here we go

First I used DialogFragment instead of PopupView.

So in my main activity, I only created a Button who calls my DialogFragment.

public class Activity_principal1 extends FragmentActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_principal1);

        Button abrir = (Button) findViewById(R.id.botao);
        abrir.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                new DialogFragmentWindow().show(getSupportFragmentManager(), "");
            }
        });
    }

}

My adapter still the same as the question.

And here is where the magic occurs.

public class DialogFragmentWindow extends DialogFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.popup, container);

        ViewPager vp_contentAcoesMusculares_SequenciaExercicios = (ViewPager) view.findViewById(R.id.vp_contentAcoesMusculares_SequenciaExercicios);
        List fragments = getFragments();
        AcoesMuscularesAdapter ama = new AcoesMuscularesAdapter(getChildFragmentManager(), fragments);
        vp_contentAcoesMusculares_SequenciaExercicios.setAdapter(ama);

        getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);

        return view;
    }

    private List getFragments(){
        List fList = new ArrayList();
            fList.add(FragmentAcoesMusculares.newInstance("Fragment 1",1));
            fList.add(FragmentAcoesMusculares.newInstance("Fragment 2",2));
            fList.add(FragmentAcoesMusculares.newInstance("Fragment 3",3));
        return fList;
    }
}

The difference is the getChildFragmentManager(). This little piece of code saved my day.

The explanation to this is when I was using getSupportFragmentManager() and even indicating the view pager was in another Layout XML he thought being in the main Layout XML.

Now my app gets the child fragment so now he sees the ViewPager.

That's it.

Thanks, everyone.
