Android: custom AlertDialog, viewPager : java.lang.IllegalArgumentException: No view found for id

Android 4.3.

My custom dialogFragment:

public class IntroductoryTourDialogFragment extends DialogFragment implements ViewPager.OnPageChangeListener {
private int totalPagesCount;
private Activity activity;

private static final String TAG = IntroductoryTourDialogFragment.class.getName();

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    this.activity = activity;
}

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    LayoutInflater inflater = activity.getLayoutInflater();
    View view = inflater.inflate(R.layout.introductory_tour_layout, null);
    AlertDialog.Builder builder = new AlertDialog.Builder(activity);
    builder.setView(view);
    setCancelable(false);
    init(view);
    return builder.create();
}

private void init(View view) {
    totalPagesCount = getResources().getStringArray(R.array.introductory_tour_images_names).length;
    SectionsPagerAdapter sectionsPagerAdapter = new SectionsPagerAdapter(getFragmentManager());
    ViewPager viewPager = (ViewPager) view.findViewById(R.id.introductory_tour_viewPager);
    viewPager.setAdapter(sectionsPagerAdapter);
    viewPager.addOnPageChangeListener(this);
}

public class SectionsPagerAdapter extends FragmentPagerAdapter {

    public SectionsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        Fragment fragment = new IntroductoryTourPageFragment();
        Bundle args = new Bundle();
        String introductory_tour_images_name = getResources().getStringArray(R.array.introductory_tour_images_names)[position];
        args.putString(IntroductoryTourPageFragment.TOUR_PAGE_NAME, introductory_tour_images_name);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public int getCount() {
        return totalPagesCount;
    }
}

@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

}

@Override
public void onPageSelected(int position) {

}

@Override
public void onPageScrollStateChanged(int state) {

}
}

My custom xml file:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:foo="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/bg">
    <android.support.v4.view.ViewPager
        android:id="@+id/introductory_tour_viewPager"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="parent" />
</android.support.constraint.ConstraintLayout>

But when try run this dialog fragment I get error: 

java.lang.IllegalArgumentException: No view found for id 0x7f0e026e
    (com.my_project:id/introductory_tour_viewPager)
    for fragment IntroductoryTourPageFragment{427e2d10 #2 id=0x7f0e026e android:switcher:2131624558:0}

The main problem is your dialog View is not created properly. Before creating View, you are trying to initialize ViewPager and set SectionsPagerAdapter to ViewPager.

SOLUTION:

1. First, remove overridden method onCreateDialog().

2. Override onCreateView() and inflate your layout introductory_tour_layout from here:

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

        return view;
    }

3. When view created successfully, initialize your ViewPager set SectionsPagerAdapter to ViewPager. To do this call method init(view) From onViewCreated():

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        init(view);
    }

4. When creating instance of SectionsPagerAdapter use getChildFragmentManager() instead of getFragmentManager():

SectionsPagerAdapter sectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager());

Here is the working code:

public class IntroductoryTourDialogFragment extends DialogFragment implements ViewPager.OnPageChangeListener {

    private int totalPagesCount;
    private Activity activity;

    private static final String TAG = IntroductoryTourDialogFragment.class.getName();

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        this.activity = activity;
    }

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

        return view;
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        init(view);
    }

    private void init(View view) {
        totalPagesCount = getResources().getStringArray(R.array.introductory_tour_images_names).length;
        SectionsPagerAdapter sectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager());
        ViewPager viewPager = (ViewPager) view.findViewById(R.id.introductory_tour_viewPager);
        viewPager.setAdapter(sectionsPagerAdapter);
        viewPager.addOnPageChangeListener(this);
    }

    public class SectionsPagerAdapter extends FragmentPagerAdapter {

        public SectionsPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {

            Fragment fragment = new IntroductoryTourPageFragment();
            Bundle args = new Bundle();
            String introductory_tour_images_name = getResources().getStringArray(R.array.introductory_tour_images_names)[position];
            args.putString(IntroductoryTourPageFragment.TOUR_PAGE_NAME, introductory_tour_images_name);
            fragment.setArguments(args);

            return fragment;
        }

        @Override
        public int getCount() {
            return totalPagesCount;
        }
    }

    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {

    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
}

To show IntroductoryTourDialogFragment , use below code in your Activity:

IntroductoryTourDialogFragment introductoryTourDialogFragment = new IntroductoryTourDialogFragment();
introductoryTourDialogFragment.show(getSupportFragmentManager(), introductoryTourDialogFragment.getTag());

This also work (without onViewCreated()):

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

        return view;
    }

Hope this will help~
