Implementing fragments

[snajdovski]

Could someone provide a sample code on how I can insert fragment I have seen issue #107 but didn't help I get tons of errors, so can someone make for me an example file with horizontal bottom nav bar with those 5 fragments?
I know that this is like begging but I am quite new to this stuff.

I dont know why.Bec. idont se your error.But this code work for me

private void initUI() {
final ViewPager viewPager = (ViewPager) findViewById(R.id.vp_vertical_ntb);
viewPager.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {
// Returns total number of pages
@OverRide
public int getCount() {
return 8;
}

        // Returns the fragment to display for that page
        @Override
        public Fragment getItem(int position) {

            switch (position) {
                default:
                    return new Fragment();///Your FRAGMENTS
            }
        }

        // Returns the page title for the top indicator
        @Override
        public CharSequence getPageTitle(int position) {
            return "Page" + position;
        }

    });

    final String[] colors = getResources().getStringArray(R.array.vertical_ntb);

    final NavigationTabBar navigationTabBar = (NavigationTabBar) findViewById(R.id.ntb_vertical);
    final ArrayList<NavigationTabBar.Model> models = new ArrayList<>();
    models.add(
            new NavigationTabBar.Model.Builder(
                    getResources().getDrawable(R.drawable.ic_first),
                    Color.parseColor(colors[0]))
                    .title("ic_first")
                    .selectedIcon(getResources().getDrawable(R.drawable.ic_eighth))
                    .build()
    );
    models.add(
            new NavigationTabBar.Model.Builder(
                    getResources().getDrawable(R.drawable.ic_second),
                    Color.parseColor(colors[1]))
                    .selectedIcon(getResources().getDrawable(R.drawable.ic_eighth))
                    .title("ic_second")
                    .build()
   );
    models.add(
            new NavigationTabBar.Model.Builder(
                    getResources().getDrawable(R.drawable.ic_third),
                    Color.parseColor(colors[2]))
                    .selectedIcon(getResources().getDrawable(R.drawable.ic_eighth))
                    .title("ic_third")
                    .build()
    );
    models.add(
            new NavigationTabBar.Model.Builder(
                    getResources().getDrawable(R.drawable.ic_fourth),
                    Color.parseColor(colors[3]))
                    .selectedIcon(getResources().getDrawable(R.drawable.ic_eighth))
                    .title("ic_fourth")
                    .build()
    );
    models.add(
            new NavigationTabBar.Model.Builder(
                    getResources().getDrawable(R.drawable.ic_fifth),
                    Color.parseColor(colors[4]))
                    .selectedIcon(getResources().getDrawable(R.drawable.ic_eighth))
                    .title("ic_fifth")
                    .build()
    );
    models.add(
            new NavigationTabBar.Model.Builder(
                    getResources().getDrawable(R.drawable.ic_sixth),
                    Color.parseColor(colors[5]))
                    .selectedIcon(getResources().getDrawable(R.drawable.ic_eighth))
                    .title("ic_sixth")
                    .build()
    );
    models.add(
            new NavigationTabBar.Model.Builder(
                    getResources().getDrawable(R.drawable.ic_seventh),
                    Color.parseColor(colors[6]))
                    .selectedIcon(getResources().getDrawable(R.drawable.ic_eighth))
                    .title("ic_seventh")
                    .build()
    );
    models.add(
            new NavigationTabBar.Model.Builder(

                    Color.parseColor(colors[7]))
                    .selectedIcon(getResources().getDrawable(R.drawable.ic_eighth))
                    .title("ic_eighth")
                    .build()
    );

    navigationTabBar.setModels(models);
    navigationTabBar.setViewPager(viewPager, 4);

[IckycHIk]

AND i have some idea. But i think that is very bad code but why not...
I create view fragment_container
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/containerFragment"

/>

And than add Fragment in this view. By position you can add Fragment

final ViewPager viewPager = (ViewPager) findViewById(R.id.vp_vertical_ntb);
viewPager.setAdapter(new PagerAdapter() {
@OverRide
public int getCount() {
return 8;
}

        @Override
        public boolean isViewFromObject(final View view, final Object object) {
            return view.equals(object);
        }

        @Override
        public void destroyItem(final View container, final int position, final Object object) {
            ((ViewPager) container).removeView((View) object);
        }

        @Override
        public Object instantiateItem(final ViewGroup container, final int position) {
            final View view = LayoutInflater.from(
                    getBaseContext()).inflate(R.layout.fragment_container, null, false);


                FragmentManager fragmentManager = getSupportFragmentManager();
                fragmentManager.beginTransaction()
                        .replace(R.id.containerFragment,new ListFragment()//Your Fragment)
                        .commit();
            container.addView(view);
            return view;
        }
    });

[snajdovski]

@IckycHIk Can you just open up android studio and quickly type the code with some placeholder fragments and post it on Mega or Google Drive?
Or the harder way I will post the errors and you correct me 👍 xD

Can you Add to your gid project? If its not posible . I have 1 question .What type of NavTab Bar you want use.I make some example for you

[snajdovski]

@IckycHIk I made it work thanks mate
