Android ViewPager (Working with Basic Tabs)

Step 1

Instantiate view pager id

viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);

Step 2

Setup View Pager adapter

 private void setupViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        /* Passing title to adapter */
        adapter.addFragment(new OneFragment(), "Featured");
        adapter.addFragment(new TwoFragment(), "Rentals");
        viewPager.setAdapter(adapter);
    }

    /* Fragment Adapter */
    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List mFragmentList = new ArrayList<>();
        private final List mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

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

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

        public void addFragment(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }

Step 3 Adding cool transition

  viewPager.setPageTransformer(true, new DepthPageTransformer());

Step 4 Transition Class

public class DepthPageTransformer implements ViewPager.PageTransformer {
    private static final float MIN_SCALE = 0.75f;

    public void transformPage(View view, float position) {
        int pageWidth = view.getWidth();

        if (position < -1) { // [-Infinity,-1)
            // This page is way off-screen to the left.
            view.setAlpha(0);

        } else if (position <= 0) { // [-1,0]
            // Use the default slide transition when moving to the left page
            view.setAlpha(1);
            view.setTranslationX(0);
            view.setScaleX(1);
            view.setScaleY(1);

        } else if (position <= 1) { // (0,1]
            // Fade the page out.
            view.setAlpha(1 - position);

            // Counteract the default slide transition
            view.setTranslationX(pageWidth * -position);

            // Scale the page down (between MIN_SCALE and 1)
            float scaleFactor = MIN_SCALE
                    + (1 - MIN_SCALE) * (1 - Math.abs(position));
            view.setScaleX(scaleFactor);
            view.setScaleY(scaleFactor);

        } else { // (1,+Infinity]
            // This page is way off-screen to the right.
            view.setAlpha(0);
        }
    }
}

Update Function Modal Box

I encountered the same problem, here is how i solved it. My modal is on the index.blade page, as follows:

<a data-toggle="modal" role="button" href="{{ URL::to('user/'.$user->id.'/edit') }}" class="btn btn-default"><i class="icon-pencil"></i></a>

Then the modal:

@if(!empty($user))
    <!-- Form modal -->
            <div id="edit_modal" class="modal fade" tabindex="-1" role="dialog">
                <div class="modal-dialog">
                    <div class="modal-content">
                        <div class="modal-header">
                            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                            <h4 class="modal-title"><i class="icon-paragraph-justify2"></i> Edit User</h4>
                        </div>

                        <!-- Form inside modal -->
                        {!! Form::model($user,array('route' => ['user.update', $user->id],'method'=>'PATCH')) !!}

                            <div class="modal-body with-padding">                               
                                <div class="form-group">
                                    <div class="row">
                                    <div class="col-sm-12">
                                        <label>First name</label>
                                        <input type="text" class="form-control" placeholder="Chinedu"
                                         name="name" value="{!! $user->name !!}">
                                    </div>
                                    </div>
                                </div>
                        {!! Form::close() !!}
@endif

@if(!empty($user))
<script>
$(function() {
    $('#edit_modal').modal('show');
});
</script>
@endif

My controller methods are:

public function index()
    {
        //View all users
        $users= User::orderBy('name', 'ASC')->paginate(10);
        return view('user.index',compact('users'));
    }

public function edit($id)
    {
        //
        $users= User::orderBy('name', 'ASC')->paginate(10);
        $user= User::findOrFail($id);
        return view('user.index',compact('users','user'));
    }

Hope this helps
