Tips

Creation of models occurs through Builder pattern.
ModelBuilder requires two fields: icon and color. Title, badge title and selected icon is optional.

You can set selected icon. Resize and scale of selected icon equals to original icon.
Orientation automatically detected according to View size.

By default badge bg color is the active model color and badge title color is the model bg color. To reset colors just set AUTO_COLOR value to badge bg and title color.
By default badge sizes and title sizes is auto fit. To reset calculation just set AUTO_SIZE value to badge size and title size.
By default icon size fraction is 0.5F (half of smaller side of NTB model). To reset scale fraction of icon to automatic just put in method AUTO_SCALE value.

If your set ViewPager and enable swipe you can action down on active pointer and do like drag.

Init

Check out in code init:

final NavigationTabBar navigationTabBar = (NavigationTabBar) findViewById(R.id.ntb);
 final ArrayList<NavigationTabBar.Model> models = new ArrayList<>();
 models.add(

new NavigationTabBar.Model.Builder(

  getResources().getDrawable(R.drawable.ic_first),

  Color.parseColor(colors[0])

).title("Heart")

  .badgeTitle("NTB")

  .build() );
 models.add(

new NavigationTabBar.Model.Builder(

  getResources().getDrawable(R.drawable.ic_second),

  Color.parseColor(colors[1])

).title("Cup")

  .badgeTitle("with")

  .build() );
 models.add(

new NavigationTabBar.Model.Builder(

  getResources().getDrawable(R.drawable.ic_third),

  Color.parseColor(colors[2])

).title("Diploma")

  .badgeTitle("state")

  .build() );
 models.add(

new NavigationTabBar.Model.Builder(

  getResources().getDrawable(R.drawable.ic_fourth),

  Color.parseColor(colors[3])

).title("Flag")

  .badgeTitle("icon")

  .build() );
 models.add(

new NavigationTabBar.Model.Builder(

  getResources().getDrawable(R.drawable.ic_fifth),

  Color.parseColor(colors[4])

).title("Medal")

  .badgeTitle("777")

  .build() );
 navigationTabBar.setModels(models);
 navigationTabBar.setViewPager(viewPager, 2);
  navigationTabBar.setTitleMode(NavigationTabBar.TitleMode.ACTIVE);
 navigationTabBar.setBadgeGravity(NavigationTabBar.BadgeGravity.BOTTOM);
 navigationTabBar.setBadgePosition(NavigationTabBar.BadgePosition.CENTER);
 navigationTabBar.setTypeface("fonts/custom_font.ttf");
 navigationTabBar.setIsBadged(true);
 navigationTabBar.setIsTitled(true);
 navigationTabBar.setIsTinted(true);
 navigationTabBar.setIsBadgeUseTypeface(true);
 navigationTabBar.setBadgeBgColor(Color.RED);
 navigationTabBar.setBadgeTitleColor(Color.WHITE);
 navigationTabBar.setIsSwiped(true);
 navigationTabBar.setBgColor(Color.BLACK);
 navigationTabBar.setBadgeSize(10);
 navigationTabBar.setTitleSize(10);
 navigationTabBar.setIconSizeFraction(0.5);

If your models is in badge mode you can set title, hide, show, toggle and update badge title like this:

model.setTitle("Here some title to model");
 model.hideBadge();
 model.showBadge();
 model.toggleBadge();
 model.updateBadgeTitle("Here some title like NEW or some integer value");

To enable behavior translation inside CoordinatorLayout when at bottom of screen:

navigationTabBar.setBehaviorEnabled(true);

To deselect active index and reset pointer:

navigationTabBar.deselect();
